Patients in unstable condition with suspected blunt abdominal trauma require rapid evaluation to assess the need for laparotomy. Ultrasonography is fast and uses portable equipment, and it can be used in the resuscitation area to detect free intraperitoneal fluid as an indication of intraabdominal injury in the patient in unstable condition. To determine the utility of emergency abdominal sonography for evaluating patients with blunt abdominal trauma, a prospective study was designed to compare ultrasonography to diagnostic peritoneal lavage. Emergency sonography was performed prior to diagnostic peritoneal lavage on 54 acutely injured patients in the resuscitation area. Our results reveal that ultrasonography has a sensitivity of 87%, a specificity of 100%, and an overall accuracy of 96% for detecting free intraperitoneal fluid. We conclude that ultrasonography is a reliable method for the emergent evaluation of blunt abdominal trauma and can be used in place of diagnostic peritoneal lavage as the initial indicator of significant intraperitoneal injury requiring surgical intervention.
病情不稳定且疑似钝性腹部创伤的患者需要迅速评估，以确定是否需要进行剖腹手术。超声检查速度快且使用便携式设备，可在复苏区用于检测腹腔内游离液体，作为病情不稳定患者腹腔内损伤的指标。为了确定急诊腹部超声检查在评估钝性腹部创伤患者中的效用，设计了一项前瞻性研究，将超声检查与诊断性腹腔灌洗进行比较。对复苏区的54例急性受伤患者在进行诊断性腹腔灌洗之前进行了急诊超声检查。我们的结果显示，超声检查检测腹腔内游离液体的灵敏度为87%，特异性为100%，总体准确率为96%。我们得出结论，超声检查是钝性腹部创伤急诊评估的可靠方法，可作为需要手术干预的明显腹腔内损伤的初始指标，替代诊断性腹腔灌洗。
