Gastric lavage or ipecac-induced emesis are routinely recommended in the management of the acutely poisoned patient. Efficacy of either procedure has not been shown. ⋯ The role of these procedures requires careful controlled evaluation. Until the publication of supportive data, their efficacy is unproven.

Carbon monoxide (CO) remains the leading cause of death due to poisoning in the United States. CO produces toxicity by binding to hemoglobin, thereby reducing oxygen-carrying capacity, and by binding to myoglobin, which may impair cardiac output and result in cerebral ischemia. Severe CO poisoning results in coma or encephalopathy, but milder intoxication may occur with nonspecific symptoms suggestive of hysteria, hyperventilation, psychosis, or viral syndrome. ⋯ Hyperbaric oxygen can shorten the half-life of carboxyhemoglobin and can carry oxygen independent of hemoglobin. However, it is not known if either 100% oxygen or hyperbaric oxygen can actually alter mortality or improve neurologic outcome in survivors. Carefully controlled prospective studies should be carried out to assess the potential value of hyperbaric oxygen in CO poisoning.

Case Reports
Free intraperitoneal cholelithiasis--a sign of traumatic perforation of the gallbladder.
Traumatic perforation of the gallbladder is relatively infrequent and is rare as an isolated lesion. The unique aspect of this case is the diagnosis of traumatic gallbladder perforation based on plain abdominal roentgenographic evidence of free intraperitoneal cholelithiasis.

Comparative Study
The relationship of the level of training and area of medical specialization with registrant performance in an advanced trauma life-support course.
Approved advanced trauma life-support (ATLS) programs were given to 160 residents and practitioners of various specialties, utilizing a standardized 50-item, multiple-choice posttest. Level of training (practitioner v resident) and area of medical specialization with registrant performance on total score and in specific subcontent areas of ATLS were evaluated by subjecting total and subcontent percent scores to a two-way analysis of variance and Newman-Keuls pairwise comparisons. Practitioners outperformed the residents in the subcontent area of abdominal injuries, P less than .05. ⋯ In airway problems, surgeons and internists were outperformed by emergency medicine, whereas in burns, emergency medicine and family practitioners significantly outperformed the surgeons. Emergency medicine outperformed internal medicine, P less than .05, in subcontent area of extremity injuries. We conclude that registrants are likely to benefit from an ATLS course, but preliminary evidence would seem to justify some "tailoring" of the ATLS curriculum for different registrant specialty groups.

The incidence of abnormalities in 1,869 sets of radiographs was recorded, and the accuracy of the interpretation of these films by emergency physicians was assessed. Abnormalities were most frequent in hip/femur (52.5%), thoracic spine (46.7%), and shoulder (44.8%) films and least frequent in skull (5.7%), cervical spine (14.9%), and foot (15.7%) films. The accuracy of interpretation by emergency physicians for all categories of films was 93.6%, with 1.8% false positives and 4.6% false negatives. ⋯ The incidence of missing existing pathology was highest for abdomen (40.0%) and knee (31.6%) films. The overall accuracy of the emergency physicians in interpretation of emergency films was excellent. Increased didactics in particular areas of interpretive inaccuracies should be considered.
