Animal laboratories have been used for many years to teach procedures. Our department has a weekly swine laboratory devoted to training residents, interns and students in resuscitative procedures. Physicians who participated in our swine procedure laboratory over the past three years were queried as to their prelaboratory and postlaboratory comfort levels with six different resuscitative procedures, and 57 (76%) physicians responded. ⋯ Of these responders, 62% offer an animal procedure laboratory. Overall, 97% of the residency directors rated the laboratory successful, and 97% of the residents rated the laboratory successful. Therefore, we conclude that an ongoing emergency medicine animal procedure laboratory is a valuable tool for improving physician-in-training ability and confidence.

Intraosseous (IO) access in adults via the distal tibia has never been a widely accepted technique. Yet there have been occasional reports of the successful use of this procedure. This study was done to demonstrate the utility of IO infusions in the adult patient, including those patients in cardiac arrest. ⋯ This study shows that I. O. access can be quickly and easily obtained in adults in the medial supramalleolar position during cardiac arrest. This method of drug administration appears to hold promise as another useful modality for adults and older children during nontraumatic resuscitations.

Emergency physicians regularly encounter patients who require local or topical anesthesia in the course of their emergency department (ED) treatment for lacerations, abrasions, or mucosal surface pain. Rarely, patients disclose a history of allergy to lidocaine and its chemical analogues, and the physician is faced with the problem of achieving adequate anesthesia without the use of these drugs. ⋯ Infiltration with a 1% diphenhydramine solution provided adequate anesthesia without noticeable adverse effects. We feel that diphenhydramine has a place in emergency medicine practice as a second-line local anesthetic agent.

Most reports of penetrating chest wounds include all regions of the thoracic wall. Recent studies of abdominal wounds stratified by entrance site have demonstrated significant differences in injury pattern that influence initial assessment and management. This is an analysis of 135 consecutive patients admitted to the Denver General Hospital with penetrating injuries to the posterior chest, done in an effort to elucidate operative indications. ⋯ Overall, 28 patients (23%) with posterior penetrating chest wounds required early surgical intervention; 38% following a GSW compared to 20% due to a SW. Only 9 patients (8%) required thoracotomy while 19 (15%) underwent laparotomy. The most frequent indication for thoracotomy was persistent chest hemorrhage, and for laparotomy, positive diagnostic peritoneal lavage.

The emergency physician must be well versed in diagnosing forearm and wrist injuries. Although many of these injuries are readily apparent, others require more sophistication to appreciate. Careful attention to radiographic findings given the assistance of a well-directed history and physical examination is imperative. Both the more common and the more subtle injuries will be discussed.
