Once fully abducted diabetes symptoms groin buy generic glimepiride 1 mg on-line, apply gentle longitudinal traction with slight external rotation diabetes prevention nih glimepiride 2 mg without a prescription. If reduction does not occur quickly diabetes mellitus type 2 cpt code buy 2 mg glimepiride amex, push the humeral head upward into the glenoid fossa diabetic blisters cheap glimepiride 2 mg buy line. Reduction can be facilitated by gently adducting the arm (after the assistant leans back to apply countertraction diabetes diet hindi discount glimepiride 1 mg buy on line. Eskimo Method With the patient supine, gently lift the arm toward the ceiling while applying gentle vertical traction. While the patient lies on the unaffected side, lift him a short distance off the ground by grasping the abducted arm of the injured side. Successful reduction is usually presaged by slight lengthening of the arm as relaxation occurs, and a noticeable "clunk" may occur at the point of reduction. A brief wave of fasciculations in the deltoid may also be seen at the time of reduction. This technique was first reported by Spaso Miljesic as a simple, single-operator technique requiring minimal force. Gently lift the affected arm vertically toward the ceiling and apply gentle vertical traction. In this technique the patient lies on the unaffected side and is lifted a short distance off the ground by grasping the abducted arm on the injured side. However, the author59 also postulated that this technique could place undue stress on the brachial plexus or axillary vessels. Use of this technique, when other options are available, should probably be reserved until more data are obtained. Noordeen and coworkers60 reported a simple method in which the patient sits sideways in a chair with the affected arm draped over the backrest. The operator holds the arm with the wrist supinated, and the patient is instructed to stand up. The patient sits in the chair, and an assistant may help support the patient by applying countertraction under the involved arm. Indirect evidence that the reduction has been successful includes an immediate decrease in pain, restoration of the round shoulder contour, and increased passive mobility of the shoulder. Alternatively, completion of this maneuver after an attempt at reduction provides strong evidence that the reduction was successful, even if the patient is still sedated. B, the best way to immobilize any reduced shoulder dislocation is uncertain and unlikely to be of consequence for a few days (see text). A typical shoulder immobilizer or a simple sling is appropriate pending orthopedic referral and follow-up. If the patient can tolerate placement of the palm from the injured arm on the opposite shoulder, it is quite likely that the shoulder reduction was successful. For patients with possible axillary nerve injury, close to 90% will recover with expectant management. Nevertheless, it is prudent to refer these patients for early orthopedic follow-up. Although most greater tuberosity fractures do not alter patient management, patients with greater tuberosity fractures displaced more than 1 cm after closed reduction almost always have an associated rotator cuff tear63 and should receive prompt orthopedic consultation because they may require operative repair. Traditional post-reduction treatment focuses on the importance of preventing the shoulder from dislocating again after the patient is discharged. This is best accomplished by immobilizing the joint with a commercially available shoulder immobilizer or a sling and swath to limit external rotation and abduction (see Chapter 50). Younger patients are usually immobilized for approximately 3 weeks and can be instructed to follow up within 1 or 2 weeks of the event. As mentioned earlier, young age confers risk of recurrent dislocation, but it is not clear if prolonged immobilization decreases recurrence rates. A 2010 meta-analysis found that immobilization for more than 1 week did not reduce recurrence rates. Several studies have shown that placing the arm in internal rotation actually increases labral detachment from the glenoid rim, whereas some degree of external rotation maximizes contact between the detached labrum and the glenoid rim. The authors of this study found that maximum contact force was actually generated in 45 degrees of external rotation, whereas no contact force was generated with the arm in internal rotation. When in doubt, a simple sling or the traditional shoulder immobilizer will certainly suffice pending 5- to 7-day follow-up. Discharge the patient with oral analgesics (either nonsteroidal antiinflammatory drugs or narcotics) to minimize discomfort and instruct them to return if the clinical condition worsens. Periodically, one may encounter a return visit from a successfully treated patient who is in severe pain from hemarthrosis. In one series of patients older than 60 years, Trimmings77 reported excellent pain relief by aspirating the hemarthrosis 24 to 48 hours after shoulder reduction. This can be accomplished by using the technique of arthrocentesis described in Chapter 53. In addition, intraarticular instillation of 10 to 20 ml of 1% lidocaine (or a longer-acting local anesthetic) may be helpful for further pain relief. Clinical Assessment Though clinically less obvious than anterior dislocations, posterior shoulder dislocations do occur in a typical, recognizable manner. The principal sign of a posterior dislocation is an arm that is somewhat fixed in adduction and internal rotation. Abduction and external rotation are limited, and attempts to perform these movements generally elicit pain. The shoulder is flattened anteriorly and rounded posteriorly, and the humeral head may be palpable. Perform a neurovascular assessment in the standard manner, but such complications are unusual with posterior dislocations. In the event of a posterior shoulder dislocation, Posterior Shoulder Dislocations Posterior shoulder dislocations account for less than 4% of all shoulder dislocations. Because the dislocation is directly posterior, there is no superior or inferior displacement of the humeral head. On superficial observation, the head of the humerus appears to maintain a normal relationship with the glenoid fossa and the acromion process. The space between the humeral head and the glenoid fossa is abnormal, and because of the extreme internal rotation of the humerus, the head and neck are seen end on and resemble a light bulb. B, On the scapular Y view it becomes obvious that the humeral head is posteriorly dislocated. It projects posteriorly under the scapular spine rather than in its normal location, centered over the glenoid fossa. The humeral head appears as a light bulb, which indicates internal rotation and is a subtle sign that a posterior dislocation might be present (arrow). B, On the axillary view the humeral head is seen to lie posteriorly and is impacted on the rim of the glenoid (arrow). When viewing axillary films, use the coracoid process to orient yourself to anterior and posterior (the coracoid is an anterior structure). Posterior shoulder dislocation causes internal rotation of the humeral head, which makes the head appear as a light bulb rather than its normal club-shaped appearance. In addition, note that the space between the articular surface of the humeral head and the anterior glenoid rim is widened (arrows), and there is a decrease in the overlap between the head and the fossa. Inferior Dislocation (Luxatio Erecta) Apply traction, internal rotation, and adduction to the affected arm. Instruct one assistant to apply countertraction (with a sheet wrapped around the waist) and another assistant to apply anteriorly directed pressure on the posterior aspect of the humeral head. As mentioned earlier in this section, ultrasound is being used increasingly for the diagnosis of shoulder dislocations, including posterior shoulder dislocations and may be useful as an adjunct to the physical exam when dislocation is clinically suspected but not radiographically apparent. Hawkins and colleagues79 suggested that posterior dislocations with an impression defect of the humeral head greater than 20% of the articular surface require open reduction. Posterior dislocations that have been diagnosed late are difficult to reduce in a closed manner, but an attempt with adequate premedication is generally indicated. Given the rarity of these injuries, orthopedic consultation is often sought early in the care of these patients. In a training environment, involvement of orthopedic residents is of benefit to their education and should be considered early. An analysis and review of the literature of posterior dislocations suggests the majority (65%) of posterior shoulder dislocations will have an associated injury (fracture, reverse Hill-Sachs injury, or rotation cuff tear) underscoring the importance of orthopedic consultation. After reduction, bring the abducted arm into adduction against the body and supinate the forearm. To perform this maneuver, place one hand on the medial condyle of the elbow and the other hand around the shaft of the humerus. Push anteriorly on the shaft of the humerus while stabilizing the medial condyle of the elbow, and rotate the humeral head from an inferior to an anterior position. The authors then describe using the external rotation method to reduce what is now a typical anterior dislocation. The coracoclavicular ligament, which has posterior (conoid) and anterior (trapezoid) components, anchors the distal end of the clavicle to the coracoid process of the scapula and therefore supports the joint in a superior-inferior direction. Unusual Shoulder Dislocations Luxatio Erecta Inferior dislocations of the shoulder, known as luxatio erecta, are quite rare but also quite obvious. The patient has the arm locked in marked abduction with the flexed forearm lying on or behind the head82. Occasionally, the humerus may have less abduction, thus potentially obscuring the diagnosis. Associated injuries include fractures of the greater tuberosity, acromion, clavicle, coracoid process, and glenoid rim. Neurovascular compression may be present, but this is usually reversed once reduction is accomplished. A, this is a rare inferior shoulder dislocation, and patients may hold their arm in marked abduction with the elbow flexed and the forearm resting on their head. Radiographs show little, if any change in position of the clavicle in relation to the acromion. Radiographs demonstrate a definite change in the relationship of the distal end of the clavicle to the acromion. The diagnosis is generally obvious, and radiographs are used mainly to rule out an associated fracture. Radiographic criteria for this degree of injury include the inferior border of the clavicle raised above the acromion or a discrepancy in the coracoclavicular distance between the normal and affected sides. Type V injury is characterized by inferior displacement of the scapula with a marked increase (two to three times normal) in the coracoclavicular interspace. Because this is usually the result of major trauma, other fractures are often present and should be sought. Radiographs are generally indicated to rule out associated fractures and to aid in assessing the degree of injury. A, Frontal chest radiograph showing asymmetry in the position of the medial margins of the clavicle, with the right clavicle (on the injured side) being located inferior to the left clavicle. B, An axial computed tomography scan confirms posterior dislocation of the right sternoclavicular joint. Weighted films are generally performed after routine "unweighted" radiographs and are obtained by strapping approximately 4. Anterior dislocations are much more common and usually the result of an indirect mechanism involving a blow thrusting the shoulder forward,63 or they may be atraumatic, caused by ligamentous laxity in teens and young adults. The clinical manifestation of these injuries is usually straightforward and consists of pain, swelling, tenderness, and deformity of the joint. Patients may complain of pain that is worse with arm movement and when they are supine. Plain radiographs of this joint are difficult to interpret and generally include an apical lordotic-type view with the radiographic tube angled 45 degrees cephalad. Children may have epiphyseal disruption with retrosternal displacement of the medial aspect of the clavicle. Apply traction on the 90-degree abducted, 10-degree extended arm in line with the clavicle and then push (anterior dislocation) or lift (posterior dislocation) the clavicle back into position. Therefore some authors recommend reduction in an operating suite unless complications necessitate immediate reduction. Once reduced, a clavicle strap may be used to immobilize both anterior and posterior dislocations for up to 6 weeks. Because of the stability of the elbow, any dislocation is expected to be accompanied by considerable soft tissue damage. Associated fractures of the radial head and coronoid process of the ulna are common. Elbow dislocations are usually simply divided into posterior and anterior dislocations. However, there are actually several additional types of elbow dislocations, including lateral, divergent, and isolated dislocations of the radius. This injury is possible with any type of elbow dislocation and is a frequent occurrence with open dislocations. The circulatory status of the arm must be carefully monitored even after successful reduction. Injury to the median and ulnar nerves may be the result of stretch, severance, or entrapment. It is difficult to clinically distinguish these causes; therefore management of nerve injuries is frequently expectant. The patient has a shortened forearm that is held in flexion, and the olecranon is prominent posteriorly. The normally tight triangular relationship of the olecranon and the epicondyles of the distal end of the humerus is disturbed in a posterior dislocation. A careful search for fractures of the distal end of the humerus, radial head, and coronoid process must be undertaken because they commonly occur in this injury. Post-reduction radiographs are also necessary to confirm reduction and disclose any associated fractures. In addition to or in lieu of parenteral sedation and analgesia, some clinicians inject the elbow joint with a local anesthetic.

A 10 to 20 mL syringe diabetes insipidus with head injury buy discount glimepiride, preferably a Luer-Lok type diabetes in dogs hypoglycemia glimepiride 2 mg buy low price, large enough to deliver the desired volume of drug solution plus an additional 5 mL of air diabetes symptoms mouth sores best purchase glimepiride. Most of the medications now prescribed for emergency situations come in prefilled syringes blood sugar 75 buy cheap glimepiride 1 mg on line. This type of apparatus does not usually allow one to draw up diluent or an additional volume of air to empty the syringe of solution blood glucose 48 glimepiride 4 mg order on-line. Keep an adequate volume of diluent available, such as normal saline or distilled water. If using a prefilled syringe, draw up an appropriate volume of diluent in a second syringe so that the total instillation volume (drug plus diluent) equals 10 mL (adults), 5 mL (children), or 1 mL (neonates). Hold the proximal end of the needle with one hand to prevent loss of the needle into the tube. If using a prefilled syringe, flush the tube immediately with the diluent in a second syringe. Use of a Catheter Draw the plunger back to add 5 mL of air to the liquid in the syringe. In addition, draw up the appropriate volume of diluent (normal saline or distilled water) plus 5 mL air into a second syringe to flush the catheter after instillation of the drug from the prefilled syringe. Rehan and colleagues36 determined that, when using a catheter in a neonatal model, more medication was delivered with an additional air flush than without an air flush. Inject the drug solution rapidly and forcefully through the catheter into the trachea followed by the 5 mL of air needed to flush the catheter of any remaining drug solution. If using a prefilled syringe, use the second syringe to promptly flush with the diluent and air. These tubes have two additional ports, one for monitoring or irrigation (opaque lumen) and one for jet ventilation (transparent lumen). If one has never seen the tube previously, determining which port is used for irrigation could prove to be time-consuming. Procedure the procedure of choice is one that will deliver the medication to the patient in the least amount of time. Dilute the drug to a final volume of 10 mL (adults), 5 mL (children), or 1 mL (neonates) with normal saline or distilled water. Advance the catheter through the endotracheal tube so that the distal end of the catheter extends 1 cm beyond the distal end of the tube. Inject the catheter with 5 mL of air to flush any remaining drug solution into the lungs. The advantage of these tubes is that the bag-valvemask device does not need to be disconnected during drug administration. As with the ported endotracheal tubes, the bag-valve-mask device does not need to be disconnected with this method. The instillation lumen opens into the tube at the Murphy eye (a hole approximately 1 cm from the end of the tube). This tube contains a separate monitoring lumen in the wall of the tube that opens inside the distal tip. A three-way stopcock with a Luer-Lok adapter provides access to the monitoring lumen. This tube is designed for bronchoscopy and has two additional ports, one for jet ventilation and one for irrigation. This tube is designed specifically for endotracheal drug administration and has two ports: one for balloon inflation and one for drug instillation. In addition to epinephrine, atropine and lidocaine also exhibit a depot effect when administered endotracheally. If total volumes are maintained between 5 and 10 mL in adults, the effect on pulmonary function appears to be minimal. Supplemental oxygen should always be administered to improve oxygenation and offset any transient drop in arterial oxygen content that might develop. This will produce a fixed dilated pupil, simulating brain death or, if unilateral, brain herniation. In adults, it has a volume of 15 to 20 mL and a total surface area of approximately 150 cm2. Each half consists of four anatomically and histologically distinct regions: the vestibule, atrium, and the respiratory and olfactory regions. The respiratory and olfactory regions are areas of high vascularity and good permeability. Olfactory Atrium Vestibule Respiratory medication has been shown for more than 30 years to be effective. Nebulized naloxone has also been used to treat opioid intoxication in the non-apneic patient. Thus, knowledge of this painless, needleless route of drug administration is important for practicing emergency physicians. Dexmedetomidine, an 2-agonist with sedative, anxiolytic, and analgesic properties can be given intranasally (2­3 mcg/ kg) to sedate children for nonpainful procedures. Onset of action is 10 to 25 minutes and its duration of action is 40 to 100 minutes (measured as ability to be discharged). Overall side effects of this medication are rare (bradycardia and hypotension) and have little effect on respiratory drive. Pediatric dosing is safe and most effective when given at a range of 1 to 3 mcg/kg. Contraindications There are no absolute contraindications to the intranasal administration of medication with the exception of medication allergy. Abnormal nasal anatomy or increased mucous production may reduce absorption and necessitate repeated dosing. Procedure Two methods to deliver drugs to the nasal mucosa can be used: drops or aerosol. Nasal drops require a cooperative patient and correct positioning to enhance drug delivery. Atomization of medication is much preferred to drops, in that much of the drug is lost to the environment by dripping out the nose or into the throat and then swallowed. If the volume is greater than 1 mL, split the dose and instill half into each naris. Position the patient properly to enhance delivery to the mucosa and prevent runoff or swallowing. One position is to place the patient on the back with the head down and nose pointing up. Slowly instill the drops into each naris along the nasal septum and allow the medication to flow into the turbinates. A second position is the lateral decubitus position with the head angled downward. Instill the drops into the naris that is "up" so that the medication runs along the nasal septum and turbinates. An alternative, though more uncomfortable position is to place the patient on the knees with the head down and the vertex parallel to the bed, essentially in a position similar to starting a forward roll. Atomization of midazolam was found to achieve higher plasma concentrations than nebulized midazolam. Draw up an appropriate volume of medication into a syringe with an additional amount to accommodate for the dead space of the device (0. An obvious advantage of an atomizer is that proper positioning is not necessary and the medication is instilled rapidly. As mentioned previously, midazolam has been noted to cause short-term local irritation. Rectal Administration Of Medication Indications Drug administration when more desirable routes are unavailable or impractical: Children frightened of intravenous catheterization Patients who refuse parenteral drug administration Patients with nausea/vomiting or inability to swallow Equipment Contraindications Immunosuppression Severe thrombocytopenia or coagulopathy Active gastrointestinal bleeding Diarrhea Chronic anorectal problems (fissures, hemorrhoids, fistulas. Most reports are anecdotal experience or case reports, and there are little data on the specific use. Weber and colleagues111 reported success with nebulized naloxone in approximately 80% of spontaneously breathing patients with suspected opioid intoxication when paramedics administered the medication. Empirical dosing is 2 to 4 mg of naloxone in 3 mL of saline, delivered by an oxygen driven nebulizer, such as those used to deliver aerosolized -agonists to asthmatics. The superior rectal vein drains into the portal circulation (by way of the inferior mesenteric vein), whereas the middle and inferior rectal veins drain into the caval system (by way of the inferior iliac vein). This pattern of venous drainage has a significant impact on the peak serum concentrations achieved by rectally administered drugs. Drugs administered high in the rectum (the area drained by the superior rectal vein) are carried directly to the liver via the portal vein and are subject to first-pass metabolism. In contrast, drugs administered low in the rectum are delivered systemically into the inferior vena cava, thereby avoiding first-pass elimination in the liver. In these situations, rectal administration may offer an alternative method of drug delivery. The major drawback to rectal drug administration is unpredictable and often erratic drug absorption. Drug absorption from the rectum is a simple diffusion process across the lipid membrane. In general, the rate of absorption rises with increasing lipid solubility of the drug and, when applicable, with increased rate of drug release from its carrier. Other factors affecting transmucosal rectal absorption include the volume of liquid, concentration of the drug, length of the rectal catheter. Patients who refuse parenteral drug administration may also benefit from rectal delivery, as will those with nausea and vomiting or an inability to swallow. Rectal administration should be avoided in immunosuppressed patients, in whom even minimal trauma could lead to abscess formation, and in patients with severe thrombocytopenia or coagulopathy to avoid difficult-to-control bleeding. Finally, patients with a variety of acute or chronic anorectal problems such as fissures, hemorrhoids, or perianal abscesses or fistulas may not tolerate rectal drug administration. Anatomy and Physiology the rectum is the terminal portion of the large intestine; it begins at the confluence of the three taeniae coli of the sigmoid colon and ends at the anal canal. In adults, the anal canal is approximately 5 cm in length and the rectum is approximately 10 to 15 cm in length. For liquid and gel formulations, use an appropriately sized syringe attached to a small. The catheter is a thin silicone tube 14-Fr in diameter with a 15-mL balloon at the tip, sized to allow secure retention, yet also provide for ready elimination in the event of need for defecation. A 3-inch piece of tape placed across the buttocks also works well and frees the clinician to perform other duties. Procedure Suppositories Place adults and large children in a lateral recumbent position on the stretcher or examination table. Place the lubricated suppository at the rectal opening and gently push it into the rectum toward the umbilicus until the gloved index finger has been inserted approximately 7. To help prevent expulsion of the suppository, do not allow the patient to get up for approximately 10 to 15 minutes after insertion. Most suppositories have an apex at one end (pointed end) and taper to a blunt base at the other end. However, in 1991, Abd-El-Maeboud and colleagues found that inserting suppositories blunt end first resulted in greater retention within the rectum and a lower expulsion rate. The goal is to deposit the drug in the low to mid-portion of the rectum to avoid first-pass elimination by the liver. When administering rectal medication to infants and young children, be sure to squeeze the buttock cheeks closed after withdrawing the catheter to Medications A variety of medications can be administered rectally. In emergency medicine practice the most common medications given rectally are analgesics and antipyretics, sedative-hypnotic agents, anticonvulsants, antiemetics, and cation exchange resins. Analgesics and Antipyretics Acetaminophen is frequently administered rectally in children for both fever and pain. Common reasons for rectal administration include refusal to take the medication orally, vomiting, and altered mental status. Acetaminophen is commercially available in suppository form and is easy to obtain and administer. Studies comparing oral and rectal administration of acetaminophen have demonstrated equal antipyretic effectiveness. For example, aspirin is commonly administered rectally to adults with symptoms of a transient ischemic attack, an acute stroke, or an acute coronary syndrome who may have an impaired swallowing mechanism or are too unstable to take medication orally. Like acetaminophen, the oral and rectal doses of aspirin are similar (see Table 26. Rectal administration of methohexital and thiopental is particularly useful for non-painful procedures such as sedating children before advanced imaging studies. To prepare a solution of methohexital for rectal administration, add 5 mL of sterile water or saline to a 500-mg vial of methohexital and mix well; this provides a methohexital solution of 100 mg/mL. Diazepam is commercially available in a gel formulation that is preloaded in a rectal delivery system (Diastat AcuDial). The preloaded rectal delivery system is available for both pediatric and adult use. The adult device contains 4 mL (20 mg) of diazepam gel and has a 6-cm tip for rectal administration. The recommended dose of diazepam rectal gel for treating actively seizing children and those in status epilepticus is 0. Prochlorperazine requires a higher dose when given rectally, whereas promethazine dosing is the same regardless of the route of administration (see Table 26. Cation Exchange Resin the most commonly available cation exchange resin is sodium polystyrene sulfonate (Kayexalate). Each gram of resin may bind as much as 1 mEq of potassium and release 1 to 2 mEq of sodium. Sodium polystyrene sulfonate may be given orally or rectally as a retention enema. Common reasons for rectal administration include an inability or refusal to swallow (the oral solution is not very palatable), vomiting, and altered mental status. The resin comes in two forms: a powder that must be reconstituted and a premixed suspension containing sorbitol.

No playing for 12 hours that requires normal coordination insulin or medication diabetes cheap 4 mg glimepiride with mastercard, such as bike riding or jungle gym activities diabetes type 1 celebrities glimepiride 4 mg buy with visa.

If you notice anything unusual about your child, call us for advice or return to the emergency department for reevaluation. The emotional state of a patient on induction strongly correlates with the degree of distress on emergence and in the days immediately after the procedure. Incorporating into the presedation preparation a discussion with the consultant about the sedation plan and the length of time required to safely prepare and sedate the patient can avoid the risks associated with hurried sedation. Wait the appropriate time for the medications to produce the intended effect before adding more doses. When using opioids, administer doses in 2- to 3-minute increments and observe for side effects such as miosis, somnolence, decreased responsiveness to verbal stimuli, impaired speech, and diminished pain on questioning as appropriate initial end points. For sedative-hypnotics, use similar incremental dosing and end points such as ptosis (rather than miosis), somnolence, slurred speech, and alterations in gaze. New drug delivery systems, however, are expanding the effectiveness and ease of use of these routes of administration. The refinement of intranasal drug delivery has significantly increased the efficacy of this route of administration. Furthermore, new drug formulations with concentrations appropriate for intranasal administration are becoming available for study. With the exception of ketamine, agents administered intramuscularly have erratic absorption and a variable onset of action. Accordingly, prolonged preprocedural and postprocedural observation may be necessary. This gas can either be delivered by a demand-flow system using a handheld mask or be delivered to young children using a nose mask in a continuous-flow system under close clinician supervision. Significant forward flexion might cause airway obstruction if the child falls asleep on the way home. Time of onset from injection to the initial observed effect must be appreciated, especially when using drugs in combination, to avoid stacking of drug doses and oversedation. The correct agent (or combination of agents) and the route and timing of administration depend on the following factors: How long will the procedure last Does the patient require sedation only for a noninvasive diagnostic imaging study The true ceiling dose of an agent is the level that provides adequate pain relief or sedation without major cardiopulmonary side effects such as respiratory depression, apnea, bradycardia, hypotension, or allergic reactions. Relative contraindications include hemodynamic or respiratory compromise, altered sensorium, or an inability to monitor for adverse events. However, even in many of these circumstances, appropriate agents can be given to provide analgesia and sedation while minimizing the chance for further deterioration. Isadelayinwaitingfora sufficient fasting time worth the time lost in performing the procedure From Krauss B, Brustowicz R, editors: Pediatric procedural sedation and analgesia. Skilled practitioners can frequently combine a calm, reassuring bedside manner with distraction techniques, careful local or regional anesthesia, or both. Despite a cooperative patient, for some procedures it is impossible to achieve effective pain control with local or regional anesthesia. Young children requiring repair of lacerations are frequently terrified, and older children and adults may be highly anxious in anticipation of such repairs in sensitive or personal regions. Immobilization is most commonly an issue with young children and the mentally challenged. The benefits of reducing anxiety and controlling pain should be carefully weighed against the risk for respiratory depression and airway compromise. Such procedures can usually be managed with topical, local, or regional anesthesia. Midazolam can be titrated intravenously to a relatively deep level of sedation, although as discussed previously, the risk for adverse effects increases with the depth of sedation. Ketamine (typically with coadministered midazolam when used in adults) can also provide the profound analgesia and immobilization necessary to perform painful procedures. However, in adults there is a risk for unpleasant hallucinatory recovery reactions. Although the pharmacopoeia is large, clinicians should familiarize themselves with a few agents that are flexible enough to be used for the majority of procedures. In all cases it is assumed that practitioners are fully trained in the technique, appropriate personnel and monitoring are used as detailed in this chapter, and specific drug contraindications are absent. Occasionally, procedures in extremely uncooperative adults or the mentally challenged are best managed in the operating room with general anesthesia. In other cases, supplementing nonpharmacologic techniques with topical or local anesthesia and anxiolysis with oral midazolam may be sufficient to permit successful wound repair. Although oral administration is most popular and least invasive, the nasal or rectal routes can also be used depending on operator experience and preference. Young children with facial lacerations at night, after their normal bedtime, may require only topical anesthesia and a quiet room for 20 to 30 minutes to achieve a painless laceration repair while the child sleeps. This can further increase hunger and irritability, especially if the child waits 1 to 2 hours to be seen by a clinician. A child who was frightened and uncooperative in triage may be calm and compliant during a procedure. An extremely anxious parent or a parent who must take care of other siblings during the procedure will find it difficult to assist in distracting the child or otherwise helping the child cope with the procedure. Direct experience is not the only way to create anxious, frightened, and uncooperative patients, though. Images from television, stories from peers, or previous witness of a sibling being forcibly restrained for repair of a laceration can leave a powerful and lasting impression. This type of influence should be especially suspected in children whose anxiety seems out of proportion to the present situation. Children manifest anxiety in many different ways, and emergency clinicians must be facile at recognizing the varying expressions of anxiety, especially in young children. A child with a facial laceration quietly sitting on the stretcher during the initial examination will not necessarily be a calm and cooperative patient during repair of the laceration Inquiring into how a child behaves during routine primary care visits can yield important information on how the child reacts to stressful situations, how cooperative the child will be with the anticipated procedure, and whether pharmacologic management is needed. Children who cry but hold still when vaccinated may be more compliant than children who are described by their parents as being "afraid of doctors" or "wild" during visits to the primary care physician. Ketamine may be the best option in such children because dissociative sedation can consistently provide immobilization and analgesia while maintaining protective airway reflexes and upper airway muscular tone. Do not attempt this procedure if the pulse oximeter, suction, oxygen, or bag-mask device is not working, the intravenous line is not secured, or the room is too small or not set up for procedural sedation and analgesia. Proceed slowly and patiently and allow the medication to take full effect before giving the next dose. An ageappropriate resuscitation cart with oral and nasal airways, endotracheal tubes, and a functioning laryngoscope must be nearby. Additionaldosesoffentanylor midazolam may be required if further pain or anxiety is noted based on the response and length of the procedure. Reversal agents should be considered if there is not a prompt response to assisted ventilation. The best choice is an agent whose pharmacologic properties are familiar to the operator, that is used frequently by the operator, is easily titratable, and has a short duration of action or is readily reversible. All drugs should be given in adequate doses because under-dosing of opioids or sedatives provides no useful purpose. Despite a wide margin of safety, chloral hydrate can cause airway obstruction and respiratory depression, especially at higher doses (75 to 100 mg/kg). When administered orally, the average time to peak sedation is approximately 30 minutes, with a recovery time of an additional 1 to 2 hours. Patients at Higher Relative Risk · Patientsolderthan55years,debilitated,orwithsignificant underlying illness. When the benefits of using propofol outweigh the risks, administer lower doses more slowly. Patients should ideally have their volume status optimized before receiving propofol. When available, consider adding a separate emergency clinician who is solely dedicated to drug administration and patient monitoring. Because it is a halogenated hydrocarbon, overdoses of chloral hydrate can be arrhythmogenic and produce ventricular dysrhythmias. Benzodiazepines are a group of highly lipophilic agents that possess anxiolytic, amnestic, sedative, hypnotic, muscle relaxant, and anticonvulsant properties. They lack direct analgesic properties and thus are commonly coadministered with opioids. Caution must be exercised when using benzodiazepines and opioids together because the risk for hypoxia and apnea is significantly greater than when either is used alone. The time to peak effect for midazolam is approximately 2 to 3 minutes when given intravenously. Unlike diazepam, midazolam and lorazepam are water soluble, thus making parenteral administration less painful and mucosal absorption faster. On occasion, the patient may move or be moved into a position that is self-maintaining. Intubation is unnecessary, but occasional repositioning of the head may be needed for optimal airway patency. Consider encouraging adults and older children to "plan" specific, pleasant dream topics in advance of sedation (believed to decrease unpleasant recovery reactions). Emphasize, especially to school-aged children and teenagers, that ketamine delivers sufficient analgesia, so there will be no pain. Avoid ketamine in patients who are already hypertensive and in older adults with risk factors for coronary artery disease. More rapid administration produces high central nervous system levels and has been associated with respiratory depression or apnea. Blood pressure measurements after the initial value are generally unnecessary because ketamine stimulates catecholamine release and does not depress the cardiovascular system in healthy patients. Supplemental oxygen is not mandatory but may be used when capnography is used to monitor ventilation. Midazolam may be used for the same indications and in the same manner as in adults. Some children require larger doses than would be typical for adults on a milligram-per-kilogram basis,85 and paradoxical responses. Individual dosages may vary when used in combination with other agents, especially when benzodiazepines are combined with opioids. When administered by skilled practitioners using standard precautions (see Box 33. Deaths from undetected apnea have occurred,84 thus underscoring the critical role of continuous interactive and mechanical monitoring. Although hypotension can occur, it is rare when the agents are carefully titrated. One reason that midazolam is ideal for painful procedures is its significant amnesic effect. Even though patients appear to feel pain during the procedure, it is often not remembered. Pentobarbital is a barbiturate capable of profound sedation, hypnosis, amnesia, and anticonvulsant activity in a dose-dependent fashion. When carefully titrated intravenously, sedation is evident within 5 minutes with a duration of approximately 30 to 40 minutes. Like other barbiturates, pentobarbital can lead to respiratory depression and hypotension because it is a negative inotrope. Critics have cited the level of continuous vigilance required to achieve a desired effect while simultaneously avoiding significant cardiopulmonary depression because these agents can result in rapid swings in levels of consciousness. It can be cautiously combined with the short-acting narcotic fentanyl or with ketamine. The pain of a propofol injection can be minimized by choosing a large vein not on the dorsum of the hand and slowly injecting 2 to 3 mL of 2% lidocaine into the vein before injection of propofol. The half-life for blood-brain equilibration is approximately 1 to 3 minutes, and its clinical effects typically resolve within 5 to 7 minutes. Propofol exhibits inherent antiemetic and perhaps euphoric properties, and patient satisfaction is typically high. Propofol should be avoided in patients with known or suspected allergy to eggs or soy products. Transient apnea and respiratory depression can occur with propofol but typically resolve spontaneously before intervention is necessary. Etomidate may be somewhat less effective overall than propofol and, given its additional adverse effect of myoclonus, appears to be a less desirable choice than propofol for deep sedation. The safety and efficacy profile of etomidate appears to be similar to that in adults. The primary adverse effects of etomidate are respiratory depression, myoclonus, nausea, and vomiting. It consists of transient jerking or twitching movements that can be mistaken for seizure activity. Clinical recovery is rapid (15 minutes) as a result of rapid redistribution from the central nervous system to the periphery. The effects of fentanyl can be reversed immediately with naloxone should excessive sedation or respiratory depression occur. The longerduration opioids morphine and meperidine are preferred for nonprocedural or preprocedural pain control and are frequently given initially for acute analgesia followed by fentanyl to facilitate the needed procedure. Fentanyl is 100 times more potent than morphine and has no intrinsic anxiolytic or amnestic properties. This increase in potency and onset of action is in part related to its greater lipid solubility, which facilitates passage of the drug across the blood-brain barrier. The effects of fentanyl can be rapidly and completely reversed with opioid antagonists. Because the opioid effect is most pronounced on the central nervous system respiratory centers, apnea precedes loss of consciousness.

A search for other more serious injuries should be undertaken when there is a high-energy mechanism of injury. Neurovascular assessment should be performed early in the evaluation and appropriately documented.

Immobilization is the mainstay of fracture therapy, but though intuitively beneficial, it is difficult to find firm scientific data that support the use of splinting for soft tissue injuries. Splinting Techniques Indications Immobilization of a variety of clinical conditions: Fractures and dislocations Deep lacerations that cross joints Tendon lacerations Inflammatory disorders. The impetus for this change is primarily related to the complications occasionally associated with circumferential casts, liability issues, and ease of application brought about by new technology. In most instances, properly applied splints provide short-term immobilization equal to that of casts while allowing continued swelling and thus reducing the risk for ischemic injury. Other obvious advantages of splints are that patients can take them off when immobilization is no longer needed or can remove them temporarily to bathe, exercise the injured part, or perform wound care. Details of the construction and application of commonly used custommade plaster splints are provided. Other benefits of splinting are specific to the particular injury or problem being treated. For example, in the treatment of fractures, splinting helps maintain bony alignment. Splinting deep lacerations that cross joints reduces tension on the wound and helps prevent wound dehiscence. Immobilizing tendon lacerations may facilitate the healing process by relieving stress on the repaired tendon. The discomfort of inflammatory disorders such as tenosynovitis or acute gout is greatly reduced by immobilization. Deep space infections of the hands or feet, as well as cellulitis over any joint, should similarly be immobilized for comfort. Hence, selected puncture wounds and mammalian or human bites of the hands and feet may be immobilized until the risk for infection has passed. Splinting large abrasions that cross joint surfaces prevents movement of the injured extremity and reduces the pain produced when the injured skin is stretched. Finally, victims of multiple trauma should have fractures and reduced dislocations adequately splinted while other diagnostic and therapeutic procedures. Immobilization decreases blood loss, minimizes the potential for further neurovascular injury, reduces the need for opioid analgesia, and may decrease the risk for fat emboli from longbone fractures. Splinting is traditionally thought of as a treatment of fractures, such as the comminuted distal radius fracture depicted in A. However, splinting is also beneficial in a wide variety of other conditions, such as B, acute gout, C, human and mammalian bites of the hand, and D, tendon injuries. Other indications include inflammatory disorders such as tenosynovitis, deep lacerations that cross joints, and deep space infections of the hands and feet. When gypsum is heated to approximately 128°C, most of the water of crystallization is driven off and a fine white powder is left behind-plaster of Paris. When water is added to the plaster, the reaction is reversed, and the plaster recrystallizes or "sets" by incorporating water molecules into the crystalline lattice of the calcium sulfate dehydrate molecules. The crinoline allows easy application, helps keep the plaster molded to the proper form during the setting process, and adds support to the finished splint. Plaster rolls and sheets are available in a variety of setting times and widths (2-, 3-, 4-, or 6-inch widths). In addition, plaster rolls and strips are generally less expensive than premade splints. Prefabricated Splint Rolls the use of plaster splints in the form of prefabricated splint rolls. These splint rolls have 10 to 20 sheets of plaster enclosed between a thick layer of protective foam padding on one side and a thin layer of cloth on the other. The major advantage of prefabricated splint rolls is that significant time is saved because the splint and padding come ready to apply. In addition, prefabricated splint rolls are ideal for intermittent splinting and can be removed and reapplied by the patient as needed. However, prefabricated plaster splint rolls are more expensive than simple plaster rolls, and they lack some of the versatility and custom-fit qualities of self-made plaster splints. Prefabricated splint rolls composed of layers of fiberglass between polypropylene padding. Fiberglass splint rolls offer the same time-saving aspect as prefabricated plaster splint rolls but require only 3 minutes to set, thus making application faster. In addition, splints made of prefabricated fiberglass rolls cure more rapidly (20 minutes), have no messy residue. Another advantage is the polypropylene padding, which wicks moisture away from the skin better than polyester, nylon, or cotton padding does. After heating, Woodcast splints are applied in the same manner as conventional splints. The material comes in slabs ranging from 1-to-4 mm thick from which the provider can cut out the desired shape for a specific splint. The composite material is easily molded to the contour of an extremity or digit by heating for 15 minutes to a temperature of 65°C using one of the Woodcast heating devices. The material takes approximately 15 minutes to set, providing sufficient time for applying and molding the splint. If needed, setting time can be reduced to 5 to 10 minutes with application of ice packs. Woodcast splints can be rewarmed and remolded after application and gloves are not required when handling the material. Compared to conventional splinting materials, Woodcast splints cause fewer skin reactions, and are associated with similar rates of healing and patient satisfaction. It protects the skin and, when folded back over the ends of the plaster, creates a smooth, professional-looking, padded rim. Padding Padding under the splint protects the skin and bony prominences and accommodates swelling of the injured extremity. Most commercially available splints contain adequate padding in the premade product, but in some instances, additional padding is prudent. Webril is soft cotton with a much coarser weave than sheet wadding; consequently, it has greater tensile strength, adheres better, and can be applied more evenly. A, Woodcast standard heating device is designed for heating all flat Woodcast materials. B, Woodcast express heating device can be used to heat flat material to create a new splint and to reheat a split that has already been applied to improve its fit. A, An elastic bandage is a popular home treatment of many painful conditions, such as sprains and contusions. B, Wrapping an extremity too tightly may cause additional injury or distal swelling. Note the grooves in the skin (arrows) indicating that the wrap was the culprit that caused the hand swelling. C, A markedly swollen foot after application of a useless elastic bandage on the lower part of the leg. This results in uniform, felt-like padding that conforms to the surface being wrapped. Some bandages use metal clips, whereas others use a Velcro-type mechanism to secure the bandage in place. Although applying an elastic bandage to an injured part is popular, it is of minimal benefit alone. The downside is that the bandage may be wrapped too tightly and cause additional injury or distal swelling. Adhesive Tape use adhesive tape to prevent slippage of the elastic bandages, to line the cut edges of a bivalved cast, and to buddy-tape digits. Coban tape can be used in a similar manner and has the advantage of adhering only to itself. Do not prepare the plaster in the sink unless it is equipped with a special drain designed to accept plaster residue without clogging. A bucket is not required for the minimal amount of water used to soften premade fiberglass splints. Roll out the appropriate layers of plaster (roughly 8 layers for upper extremities, 12­15 for the lower). The stockinette should extend 10­15 cm beyond both ends of the area to be splinted. Using warmer water may cause thermal injury, because the plaster releases heat when activated. Lay the plaster out on a table and smooth further to remove all wrinkles and ensure uniform lamination of all layers. A layer of Webril may be placed over the plaster to prevent it from sticking to the elastic wrap. Secure the splint to the extremity with an elastic wrap by proceeding in a distal-to-proximal fashion.
