Abstract:
Pasquier, Mathieu, Louis Marxer, Hervé Duplain, Vincent Frochaux, Florence Selz, Pierre Métrailler, Grégoire Zen Ruffinen, and Olivier Hugli. Indications and outcomes of helicopter rescue missions in alpine mountain huts: A retrospective study. High Alt Med Biol 18:355-362, 2017.
Aims:
This retrospective study describes the rescue indications and outcome of patients rescued by helicopter from mountain huts in the Swiss Alps. The hospital course and operational data were also studied.
Results:
Among 14,872 helicopter rescue missions undertaken during the 10-year study period, 309 (2.1%) were performed from mountain huts at a mean altitude of 2794 ± 459 m. The mean age of the patients was 43 ± 16 and 66% were male. Thirty-four percent of the patients had a National Advisory Committee for Aeronautics score ≥3. Most (89%) patients were transported to hospital and only 12 (3.9%) patients had to stay more than 48 hours. Hospital diagnoses were extremely varied. Trauma accounted for 50% and altitude diseases for 7% of the cases. A winching procedure was performed 18 times and 19 missions included a night flight.
Conclusions:
Helicopter rescue missions in mountain huts are a small part of all rescue missions. Our study provides a better understanding of medical emergencies arising in mountain huts. The diagnoses encountered are extremely varied in their type and severity. Hut keepers should be prepared for these situations as they will often have to act as first responders in the case of medical problems.
