Evaluation of the helicopter in aeromedical transfers

Since the end of the Vietnam conflict, the technology of moving patients by helicopter has been applied to peacetime uses. There is doubt, however, that the helicopter has much to offer the patient when used as a routine and semi-emergency ambulance. This study reviewed 52 consecutive aeromedical evacuation requests which included both civilian and military patients. By comparing the patient's condition at both pickup, delivery and his subsequent course, it was determined that most patients would not have been unduly harmed by the slower methods of ground transfer. Only 33% of the patients were benefitted by rapid aeromedical transfer. Those patients benefitted can roughly be grouped as true surgical and medical emergencies. The use of the helicopter for routine transfers is to be discouraged.
