Objective: The delivery of a safe an effective analgesia is a core principle and a priority of prehospital care. Analgesia in hostile environments (mountain settings, etc.) presents various challenges, and the benefit-risk ratio of the procedure should be evaluated. The objective of this study was to examine pain management strategies and the time spent on scene for analgesia provisions in an alpine environment. Methods: We undertook a retrospective study from a single physician-staffed helicopter emergency medical service in the Swiss Alps. Patients with isolated limb injuries were included. We examined the choice and route of analgesic medication, patient monitoring, medical co-treatments and time delays during the rescue mission. Results: Analgesia was provided to 657 (57%) of the 1156 included patients. Fentanyl was most commonly administered followed by ketamine, with or without fentanyl. Heart rhythm monitoring, oxygen administration, and saline infusion were used infrequently, but were used significantly more often in patients treated with ketamine. The median time on site was 6 minutes longer for patients receiving intravenous analgesia compared with those not receiving it. Conclusion: Analgesia in hostile environments seems to be limited to essential procedures. The safety of this approach must be confirmed.
