As the use of helicopters for air transport of critically ill patients increases, the availability of monitoring devices for physiological parameters during flight becomes important. It has long been known that arterial PO2 (PaO2) decreases during unsupplemented, non-pressurized flight. In this study, the authors examined the use of the transconjunctival oxygen (cjO2) monitor for assessing the adequacy of arterial oxygenation during helicopter flight in four healthy volunteers. ⋯ The relationship between cjO2 and PaO2 was linear with a regression coefficient of 1.147. The authors conclude that the transconjunctival O2 monitor may be useful for monitoring the adequacy of arterial oxygenation during helicopter flight in hemodynamically stable patients. The results of study also support the use of supplemental oxygen in all patients subjected to helicopter transport.

An unusual case of a misdirected nasogastric tube is described. An elderly woman was brought to an emergency department following intentional drug overdose. Initially unrecognized errant placement of a large-bore nasogastric tube resulted in tension pneumothorax, pneumonia, and subsequent death. Pertinent medical literature is reviewed, clinical considerations for the elderly patient are discussed, and suggestions for proper nasogastric tube placement are offered.

A case of massive degloving injury of the trunk, with open pelvic fracture, and evisceration of abdominal contents from blunt trauma is presented. The most significant aspect of this case was the transfusion of 173 units of packed cells and 176 units of fresh frozen plasma in the first thirty hours. The patient ultimately recovered and returned to work.

Boerhaave's syndrome represents a diagnostic dilemma for the emergency physician. The prognosis of this truly life-threatening emergency is darkened by any significant diagnostic delay. Unfortunately, classic or expected symptoms and signs are frequently absent at presentation, a circumstance that leads to frequent misdiagnosis. ⋯ However, emphasis should be placed on the fact that this entity may occur without emesis. The chest radiograph is the most helpful diagnostic aid. Undoubtedly, maintenance of a high degree of suspicion by the emergency physician for Boerhaave's syndrome will lead consistently to earlier diagnosis, and subsequent aggressive intervention should result in considerable reduction in rates of both morbidity and mortality.

Antibiotic prophylaxis in intraoral wounds.
This study of 100 patients was undertaken to determine the efficacy of penicillin/erythromycin prophylaxis in the management of intraoral lacerations in the pediatric population. Only six patients of the evaluable population developed infections (6.4%). Two of these patients received antibiotic prophylaxis (4%), and the other four were control patients (8%) who developed wound infections (P = 0.41). ⋯ Cross-product ratios for these small sample subgroups indicated that the likelihood of infection for non-prophylactically treated patient wounds of greater than 1 cm length and/or those requiring suturing was two to three times higher than that of patients treated prophylactically. Although no statistical significance could be ascribed to the observed differences of these post hoc categories, benefit from antibiotic prophylaxis may have been quantifiable in a study designed to assess only these major wounds utilizing a large sample size. In general, routine antibiotic prophylaxis appears unwarranted for simple intraoral lacerations in children, although it may be useful when the wounds are large enough to be sutured.
