Early Access to Patients with Life‑threatening Cardiovascular Disease by an Air Ambulance Service
2004
The purpose of this study was to determine whether use of an air ambulance service using a helicopter with a critical care physician and nurse on board(doctor helicopter service; DHS)could shorten the prehospital delay. We evaluated the initial treatment time and the transport time in 30 patients transported by DHS and 30 patients transported by ground ambulance service(GAS) . The initial treatment time was significantly shorter in the DHS group(11.3+ -5.4 min)than in the GAS group(29.5+ -15.3 min) . But the transport time in the DHS group(26.1+ -8.6 min)was not different from that in the GAS group. The difference in the initial treatment time was remarkable for patients transported from distant areas(12.7+ -5.6 min for DHS and 42.1+ -13.8 min for GAS)and DHS shortened the initial treatment time by 30 min compared with GAS. The transport time was shorter for DHS (30.5+ -9.9 min) than for GAS (42.1+ -13.8 min) for patients transported from distant areas but it was not significantly different for patients transported from nearby areas(22.3+ -5.0 min for DHS and 18.4+ -2.4 min for GAS) . In conclusion DHS is important in the management of life‑threatening cardiovascular diseases and has a significant impact when GAS cannot transport a patient to the hospital within 20 min.
