ABSTRACT
Using of airplane or helicopter could play an important role in decreasing patients' mortality regarding the importance of reducing time of transmission and treatment. This paper aims to study the transferred patients' demography to Imam Khomeini hospital of Tehran by relief helicopter in order to make good use of facilities for injured triage. In this research patients files transferred to the Imam Khomeini hospital by air rescue and relief, were studied in terms of trauma epidemiology and how emergency services were done since the established air emergency on June 2000 to the end of March. About 92% of 158 patients were hurt in the accident. According to the results, the most common injured organs were the extremities, head and neck. And the worst damage was seen in multiple trauma patients who suffered from the injury to head, neck and thorax. Also, it takes about 23 minutes between the arrival of a patient to the emergency and her/his first visit. Most patients were treated with general surgery and orthopedic services. It is necessary to use appropriate criteria for patients screening in air rescue and relief. The large number of patients are in urgent need of orthopedic and general surgery services, so it is essential that the air rescue and relief should be equipped with facilities
