目的　探讨腹腔邻近组织器官复合性外伤引起血性腹膜炎行保守治疗的条件。方法　回顾分析合并血性腹膜炎行保守治疗 2 2例。结果　通过CT检查损伤部位及血腹存在的具体位置 ,观察出血性休克的动态发展 ,行反复多次的腹腔诊断性穿刺及腹腔引流 ,并注意腹围的绝对尺寸、腹膜炎的进展 ,心率、血压的波动、中心静脉压等系列ICU的监护指标 ,以及血常规的动态观察 ,能为临床血性腹膜炎行保守治疗提供参考。结论　正确诊断腹腔邻近组织器官复合性外伤引起微量的血腹 ,并行保守治疗能提高复合外伤的抢救成功率。 Objective To investigate the conditions of conservative treatment of bloody peritonitis caused by traumatic complications in the adjacent tissues and organs of abdominal cavity. Methods Retrospective analysis of conservative treatment of bloody peritonitis in 22 cases. Results CT scan of the specific location of the site of injury and blood supply to observe the dynamic development of hemorrhagic shock, repeated repeated paracentesis and peritoneal drainage, and pay attention to the absolute size of abdominal circumference, peritonitis, heart rate, blood pressure Of fluctuations, central venous pressure and other series of ICU monitoring indicators, as well as the dynamic observation of blood can provide a reference for the conservative treatment of clinical bloody peritonitis. Conclusions Correct diagnosis of traumatic complications caused by traumatic complications in the adjacent tissues and organs of the peritoneal cavity results in a small amount of blood transfusions. Concurrent conservative treatment can improve the successful rescue rate of combined trauma.
