The clinical findings of nine patients who suffered disruption of the subclavian artery following blunt thoracic trauma were reviewed. Seven patients were men, two were women. Their ages ranged from 16 to 43 years. ⋯ Thus four of the seven patients who survived to undergo chest roentgenograms had films that suggested injury to the arch of the aorta or its branches. Seven patients survived long enough to undergo operative repair; one of these patients died (14%). The following five criteria should alert the physician to the possibility of subclavian arterial injury following blunt thoracic trauma: 1) fractured first rib; 2) diminished or absent radial pulse; 3) palpable supraclavicular hematoma; 4) chest film evidence of hematoma over the area of the subclavian artery or a widened superior mediastinum; and 5) brachial plexus palsy.

Reported is a case of primary amebic meningoencephalitis diagnosed in the emergency department. The patient, a previously healthy teenager, developed Naegleria meningoencephalitis after swimming in a freshwater public pool. The Naegleria caused acute fulminating infection culminating in the death of the patient 36 hours after admission. Results of a spinal tap, together with the history of swimming in warm fresh water, led to the emergency department diagnosis.

Randomized Controlled Trial Clinical Trial
Efficacy of pneumatic trousers in refractory prehospital cardiopulmonary arrest.
Persons refractory to early application of advanced cardiac life support have a dismal prognosis. New modalities are needed to treat this almost universally lethal condition. We have evaluated pneumatic trousers in the treatment of refractory cardiopulmonary arrest. ⋯ The improvement in resuscitation rate with pneumatic trousers was statistically significant only for the initial rhythm of PIVR (P less than .05). The pneumatic trousers improved resuscitation and discharge rates for refractory VF, but not to a statistically significant degree. These somewhat enhanced resuscitation and discharge rates with the pneumatic trousers make it an adjunct to be considered in refractory arrest.

An annual survey of emergency medicine (EM) graduate physicians from 31 programs was conducted from 1977 through 1979. Results of the 1979 data are presented. Practice patterns show that 96% of the EM graduates are providing patient care, and almost half are working in the states in which they trained. ⋯ Other activities of EM graduates include teaching medical students and residents, administration, research, and community emergency medical services. Data are analyzed with attention to long-term commitment to emergency medicine. Implications for manpower needs are suggested.
