Ground transport from a remote helipad at a trauma center may delay patient arrival in the ED and affect patient morbidity and mortality. Prehospital care providers must be aware of the magnitude of any delay when selecting the most expedient means of transport for trauma patients. This study quantifies the time required for a 0.6-mile ground transport from a remote trauma center helipad to an ED through two traffic signals along one city street.
The trauma registry was queried for all patients transported directly from the scene to the regional trauma center by helicopter between January 1993 and October 1996. Prehospital records were used to supplement missing time data; patients with incomplete data were excluded. Ground transport time was calculated by subtracting the time that the helicopter arrived at the remote helipad from the time the ambulance arrived at the ED. Mean ground transport time and standard deviation were calculated.
Three-hundred-eighty-nine trauma patients were transported directly from the scene to the regional trauma center by helicopter. Complete data were available for 345 patients (89%). Mean ground transport time was 5.2 +/- 2.3 minutes.
The need for ground ambulance transport from this remotely located trauma center helipad adds more than 5 minutes to total prehospital time. This delay in ED arrival may be significant for some patients and should be taken into account when selecting the most appropriate mechanism of patient transport and planning helipad construction.
从创伤中心的偏远直升机停机坪进行地面转运可能会延迟患者到达急诊科的时间，并影响患者的发病率和死亡率。在为创伤患者选择最便捷的转运方式时，院前护理人员必须了解任何延迟的程度。本研究量化了从偏远创伤中心直升机停机坪沿一条城市街道经过两个交通信号灯到急诊科进行0.6英里地面转运所需的时间。
查询创伤登记处，获取1993年1月至1996年10月期间所有通过直升机从现场直接转运至区域创伤中心的患者信息。院前记录用于补充缺失的时间数据；数据不完整的患者被排除。地面转运时间通过用救护车到达急诊科的时间减去直升机到达偏远直升机停机坪的时间来计算。计算平均地面转运时间和标准差。
389例创伤患者通过直升机从现场直接转运至区域创伤中心。345例患者（89%）有完整数据。平均地面转运时间为5.2±2.3分钟。
从这个偏远的创伤中心直升机停机坪进行地面救护车转运，使院前总时间增加了5分钟以上。急诊科到达时间的这种延迟对一些患者可能很重要，在选择最合适的患者转运方式和规划直升机停机坪建设时应予以考虑。
