Helicopter Critical Care Retrieval in a Developing Country: A Trauma Case Series from Bhutan

Background: The care of victims of traumatic injuries requires an organized system to achieve the best outcomes. Dispatch of specialist physicians, paramedics, and nurses to the patient by helicopter can reduce mortality. Countries in the developing world share the challenge of providing timely medical care to trauma victims, while facing others such as a higher trauma burden, poor infrastructure, inadequate government resources, organizational constraints, a lack of technical expertise, and prohibitive costs. These challenges can severely limit the provision of critical prehospital trauma care. Methods: We reviewed the prehospital trauma database to identify victims of trauma who required aeromedical evacuation as determined by the national triage system of Bhutan during the 4-month period after the establishment of the national Bhutan Emergency Aeromedical Retrieval (BEAR) team. We collected the patients' age and gender, description of injuries, mechanism of injury, interventions undertaken by the critical care retrieval team, and patient outcomes (alive vs. dead). Results: During the first 4 months of service, BEAR cared for 16 trauma patients. Fourteen patients survived to hospital discharge; two died after hospitalization. No patient died on scene or during transport. The team successfully treated several challenging casualties, including a patient gored by a water buffalo leading to traumatic cardiac arrest with successful resuscitation, victims of a compressed gas cylinder explosion, a bear mauling, and a penetrating arrow injury to the head. The team performed a variety of critical care interventions, including induction and maintenance of anesthesia, orotracheal intubation, mechanical ventilation, tube thoracostomy, administration of blood products, and successful management of traumatic cardiac arrest. Conclusion: A critical care helicopter retrieval team can deliver trauma care in a developing country, such as Bhutan, with favorable outcomes at low cost.
