Extrication of entrapped patients from car accidents takes time. To save time a new technique based on reversing the forces of the original crash by anchoring the rear of the vehicle and pulling the steering wheel and the front window pillars forward with chains is developed. In an experimental randomised trial of extrication of volunteers from car wrecks after frontal/oblique impacts we wanted to evaluate the time spent with a new extrication technique (n=6) compared to standard (n=6). Main outcome measures were time to patient free and to patient on a stretcher. It took significantly longer (s) with the standard than the new technique to start extrication [(60 (45, 70) versus 30 (30, 40), confidence interval (CI) 5-40, P=0.009], to patient free in the front seat [514+/-102 versus 238+/-72, CI 163-389, P=0.001], backboard in place [543+/-102 versus 295+/-76, CI 132-363, P=0.001], and patient on the stretcher ready for transport to the hospital [617+/-112 versus 387+/-65, CI 112-347, P=0.001]. Avoiding uncontrolled movements in the wreck was not more difficult with the new than the standard technique.
从车祸中解救被困患者需要时间。为了节省时间，人们开发了一种新技术，即通过固定车辆后部并用链条向前拉动方向盘和前窗支柱，来逆转原始碰撞的力量。在一项关于在正面/斜向碰撞后从汽车残骸中解救志愿者的实验性随机试验中，我们想评估与标准技术（n = 6）相比，一种新的解救技术（n = 6）所花费的时间。主要结局指标是患者解脱的时间以及患者被抬上担架的时间。与新技术相比，标准技术开始解救所需的时间明显更长（秒）[（60（45，70）对30（30，40），置信区间（CI）5 - 40，P = 0.009]，在前排座位上使患者解脱的时间[514±102对238±72，CI 163 - 389，P = 0.001]，放置背板的时间[543±102对295±76，CI 132 - 363，P = 0.001]，以及患者被抬上担架准备送往医院的时间[617±112对387±65，CI 112 - 347，P = 0.001]。使用新技术避免在残骸中出现不受控制的移动并不比标准技术更困难。
