重度心肌挫伤急诊诊断方法的探讨

Emergency diagnosis of severe myocardial contusion

目的:探讨重度心肌挫伤的急诊诊断方法。方法:对30例严重钝性胸部创伤患者分别在伤后1、2、4、8h行心肌标志物检测和超声心动图检查。结果:伤后8h肌钙蛋白T(Cardiac troponinT,cTn-T)和肌钙蛋白I(Cardiac troponinI,cTn-I)均明显高于伤后1h,伤后左心室心功能部分指标有明显改变。结论:心肌标志物联合超声检查对重度心肌挫伤有较高的急诊诊断价值。

Objective：To evaluate the emergency diagnosis of severe myocardial contusion. Methods：Thirty patients with serious blunt chest trauma underwent sonourethrography,all of whom underwent conventional myocardial markers simultaneously.All the observation time phases were set as 1 h,2 h,4 h and 8 h after injuries. Results：Both the concentrations of cardiac troponin T （cTn-T）and cardiac troponin I（cTn-I） at 8h after injuries were significantly higher than those at lh after injuries（P〈0.05orP〈 0.01）. Part of the left ventricular function was remarkably decreased（P〈0.05orP〈0.01）.Condusion：Using myocardial markers combined with sonourethrography may provide a more valuable way in the emergency diagnosis of severe myocardial contusion.
