【摘要】 目的探讨超声在应急事件现场诊断浅表组织异物的价值。方法应用超声检查了178例汶川地震造成的浅表组织损伤的患者,将超声诊断异物结果与手术对照。结果应急现场超声诊断浅表组织异物的阳性率为86.7%、敏感性100.0%、特异性88.0%、符合率93.3%,不同质地的异物超声诊断的阳性率从高到低依次为金属(100%)、玻璃(86.4%)、沙石(85.4%)、木屑(64.6%)(P<0.05)。异物的位置以距离损伤口1～3cm内者居多(57.7%)(P<0.05)。结论超声是应急事件现场诊断、定位浅表组织异物的可行方法。更多还原

【Abstract】 Objective To appraise the value of ultrasound to diagnose superficial tissue foreign body in emergency scence.Methods Total 178 patients in Wen Chuan earthquake who suffered from superficial tissue injury were enrolled,all of whom were checked by ultrasound. The ultrasound diagnosis and result of operation were compared.Results Positive rate of ultrasound to diagnose superficial tissue foreign body in emergency scence was 86.7%,sensitivity of which was 100.0%,specificity was 88.0% and coincidence was 93.3%. In all kinds of foreign bodies from high positive rate to low,one by one,first of which was mental(100%),then was glass(86.4%),third was sandstone(85.4%),and last was chip(64.6%)(P<0.05). Most of the foreign body were 1~3 cm distance from the wounds(57.5%,P<0.05).Conclusion Ultrasound was a reliable method to diagnose and locate superficial tissue foreign body in the scene of emergency.更多还原
