急诊超声检查在创伤性血胸诊断中应用168例分析

Analysis of Emergency Ultrasound Performed in 168 Traumatic Patients for Diagnosis of Haemothorax

目的:评估急诊超声检查在创伤性血胸诊断中的应用。方法:对168例胸部创伤病人进行了急诊胸部超声检查,并对其检查结果进行分析。结果:168例中26例阳性,142例阴性,无假阳性,假阴性2例。超声检查对创伤后血胸诊断的敏感性为93%,特异性为100%,阳性预测值为100%,阴性预测值为99%。检查时间明显短于胸片检查。结论:急诊超声检查能够迅速、准确地检查出胸部创伤病人中血胸的存在,对重症创伤病人的早期分类、诊断和治疗具有重要的参考价值,值得临床上推广应用。

Objective：To evaluate thoracic ultrasound for the diagnosis of haemothorax in patients with thoracic trauma. Methods：Thoracic ultrasound was performed in 168 patients with thoracic trauma to detect haemothorax. The findings and the time taken to diagnosis were analyzed. Results： In 168 eases, 26 cases were detected haemothorax by ultrasound and confirmed by computed tomography or intercostals drain or exploratory thoracotomy. There were 26 true positives, 140 true negatives, no false positives, and two false negative. The sensitivity of ultrasound was 93% and specificity was 100% with a positive predictive value of 100% and negative predictive value of 99% for the detection of haemothorax after trauma. The time taken by ultrasound was obvious shorter than it taken by supine chest radiography. Conclusions：Emergency ultrasound of the chest performed as part of the primary survey of the traumatized patient can rapidly and accurately diagnose haemothorax and is a valuable tool to augment the immediate clinical assessment of the patients.
