A study of "Doctor Heli" air ambulance utilization and perinatal outcomes in Fukushima Prefecture, Japan.

Many countries have adopted the use of helicopter emergency medical services (HEMS). One such system in Japan is called "Doctor Heli" (Doctor Helicopter), which is sometimes used as a means of maternal transport. Since 2008, there have been 18 cases of Doctor Heli maternal transport to Fukushima Medical University Hospital, the ultimate referral center of Fukushima Prefecture. Reasons for transport included umbilical cord prolapse (UCP), placental abruption, traffic accident, and fetal bradycardia. There were two cases of intrauterine fetal death upon arrival at the hospital. Although there is no specific requirement for an obstetrician to be on board, we encountered a case of UCP in which an obstetrician examined a patient and then traveled with her via helicopter ; the baby was successfully delivered at a tertiary care facility. In cases such as UCP, where immediate assessment of fetal condition is critical, involvement of an obstetrician prior to or during transport can be vital. Because aeromedical dispatch can connect doctors and patients more quickly, it may improve perinatal outcomes.
