RESUMEN
Mountain climbing is a popular recreational activity with a growing number of participants and associated fatalities. To define the characteristics of these fatal incidents and the typical autopsy findings in the victims, we reviewed the autopsy and investigative findings of all fatalities that occurred on Mount Rainier from 1977 through 1997. A total of 50 deaths occurred in 29 separate incidents. Fifty-eight percent of accident victims died as the result of a fall; another 34% died as a result of an avalanche. The incidents leading to death occurred at an average altitude of 3652 m (11,977 feet); range, 2073 to 4389 m (6800-14,400 feet). The average age of the victims was 31.2 years (range, 17-55 years), and 47 of the 50 were men (94%). Bodies were not recovered in 13 cases (26%). Autopsies were performed in 30 of the remaining 37 cases. At autopsy, the cause of death was ascribed to multiple injuries in 12 cases (40%), isolated head and neck injuries in 7 cases (23%), and chest injuries in 1 case (3%). Asphyxia and hypothermia were the cause of death in 8 cases (27%) and 2 cases (7%), respectively. The frequency of specific injuries is presented by anatomic region. The unique autopsy and investigative features of mountaineering deaths are discussed.

Two college students developed symptoms of poisoning following ingestion of a salt solution during a college physiology laboratory exercise. Symptoms included nausea, vomiting, diarrhea, and altered consciousness. The ingested solution was identified as isotonic buffered saline containing sodium azide in a concentration of 1.0 g/L. The solution was commercially prepared for instrumentation use only and was used inadvertently for the exercise instead of freshly preparing sodium chloride in water. One student drank three sips of the solution and survived. The other student drank 700 to 800 mL and over several days became progressively ill, suffering myocardial damage and cardiac dysrhythmias, and, finally, died. Toxicologic studies confirmed the presence of azide in an antemortem urine sample from the deceased. Sodium azide is an uncommon but potent poison which can cause serious illness and death.
