开腹术后早期腹腔残余气体影响因素的观察及分析

目的观察不同条件下开腹术后早期腹腔残余气体状况，探讨影响开腹术后早期腹腔气体残留的主要因素并分析原因。方法以切口部位、是否放置负压闭式引流为影响因素将纳入病例分组，在术后早期采用立位腹部平片方法，观察各组膈下游离气体存在情况。结果负压闭式引流下，术后早期立位腹部平片几乎未见膈下游离气体。无负压闭式引流者，下腹切口未见膈下游离气体，上腹切口均见游离气体且与切口大小无关。结论开腹术后腹部平片可见的残余气体与是否放置负压闭式引流、切口部位有关，与切口大小、年龄、性别及疾病类型无关。

Observation and Analysis of Influencial Factors of Residual Gas in Early Time after Abdominal Opration

ObjectiveTo observe the residual gas conditions of paitients after abdominal operation under different conditions, and to explore the main factors of all conditions affecting residual gas and analyze their causes. MethodsUsing the incision site and whether place closed suction drainage as the main influencing factors of the case groups, we observed subphrenic free gas of each case by upright abdominal plain film. ResultsAlmost no subphrenic free gas was observed in cases with closed drainage under negative pressure in early postoperative time,as well as lower abdominal incision cases without closed negative pressure drainage. But subphrenic free gas was found in almost all up- abdominal incision cases without closed negative pressure drainage, which was little correlated with the size of the incision.ConclusionThe residual abdominal gas in early post-abdominal-operation is correllated with the incision site and closed suction drainage, and is unrelated with the incision size, age, sex and disease type.
