To assess how soon rural emergency departments (EDs) call for helicopters to transport seriously injured patients, the records of all trauma victims (excluding isolated CNS trauma) transported by an emergency helicopter service from referring hospitals to a trauma center over an 18-month period were studied. Admission time to the referring ED was compared with the exact time a call for the helicopter was received and a time-to-request interval (TTR) was calculated. A total of 64 cases were studied. Fifty (78%) of the patients had blunt trauma; 14 (22%) had penetrating trauma. The average TTR for the helicopter was 69.8 minutes, with a range from 17 minutes before arrival at the referring ED to 337 minutes after arrival. Children (aged less than or equal to 16 years) had an average TTR of 34.1 minutes compared with 76.4 minutes for adults (aged greater than 16 years). Of the variables examined, patient age was the only factor significantly associated with TTR. These observations suggest that, except in children, there frequently is a lengthy time interval between the time trauma patients arrive at EDs in rural eastern North Carolina and the time an emergency helicopter service is called to transport them to a trauma center.
为评估农村急诊科（ED）呼叫直升机转运重伤患者的速度有多快，我们研究了一家紧急直升机服务机构在18个月期间将所有创伤受害者（不包括单纯性中枢神经系统创伤）从转诊医院转运至创伤中心的记录。将患者进入转诊急诊科的时间与接到直升机呼叫的确切时间进行比较，并计算请求时间间隔（TTR）。共研究了64例病例。其中50例（78%）患者为钝器伤；14例（22%）为穿透伤。直升机的平均TTR为69.8分钟，范围从到达转诊急诊科前17分钟到到达后337分钟。儿童（年龄小于或等于16岁）的平均TTR为34.1分钟，而成人（年龄大于16岁）为76.4分钟。在所检查的变量中，患者年龄是与TTR显著相关的唯一因素。这些观察结果表明，除儿童外，在北卡罗来纳州东部农村地区，创伤患者到达急诊科至呼叫紧急直升机服务将他们转运至创伤中心之间，通常存在较长的时间间隔。
