机械故障是飞行员紧急跳伞的主要原因[1]。自1944年德国空军飞行员首次使用弹射跳伞方式成功逃生以来,弹射跳伞已拯救上万名飞行员的生命,但弹射伤(ejection injury)的发生率仍高达50%~90%[2-4]。本文报道两名飞行员紧急弹射跳伞致伤的救治经验,并分析其可能的致伤机制。1病例资料1.1致伤原因两名飞行员在夜间训练中因飞机机械故障导致飞机失控而紧急弹射跳伞,当时飞行高度约 Mechanical failure is the main reason for pilot emergency parachuting [1]. Since the first flight of the German Air Force pilots using a catapult to parachute successfully in 1944, catapult parachutes have saved the lives of tens of thousands of pilots, but the incidence of ejection injuries is still as high as 50% to 90% [2-4]. This article reports two pilots emergency ejection parachuting injury treatment experience, and analyze its possible mechanism of injury. 1 Case Information 1.1 Causes of Injury Two pilots in the night training due to mechanical failure of the aircraft led to the uncontrolled flight emergency landing parachuting when the flight height of about
