Impact of urban disaster on a university trauma center.

On the eve of the 1984 Summer Olympics, a deranged man drove his car at high speed onto a pedestriancrowded sidewalk in a suburb of Los Angeles. The UCLA Medical Center, located two blocks from the scene, received 17 of 51 casualties. One patient arrived in full cardiac arrest and could not be resuscitated. Six had minor injuries or temporary hysteria and did not require admission to hospital. The mean injury severity score of the 10 patients who were admitted was 13.6 (range 3 to 48). Three patients required immediate surgical procedures, and two had delayed orthopedic operations. Specialty consultations were needed in orthopedics, neurosurgery, plastic surgery, otolaryngology, pediatric surgery, and pediatric intensive care. There were no subsequent deaths, although two patients had substantial residual neurologic disability. This episode of unexpected urban violence underscores the need for dedicated trauma services in university centers. Functions of such services include disaster planning, deploying surgical personnel, managing injured patients, and analyzing outcomes.
