Résumé
Objective To discuss application of double pipe for negative pressure drainage in reducing intra-abdominal infections after gastrointestinal operation.Methods 85 patients with intra-ahdominal drainage after gastrointestinal operation were randomly divided into the control group (43 patients) and the observation group(42 patients).The control group used traditional latex drainage,the observation group took the double cannula negative pressure continued drainage.The intra-abdominal infection and bacterial number distribution,patients drainage time,drainage volume and drainage tube occlusion were observed.Results 25 bacterial cultures were positive in two groups of patients.Compared between the two groups,the bacterial number detection rate were significant.31 pathogenic bacteria were detected in 25 specimens.Compared between these two groups,staphylococcus aureus,clearing time of drainage,drawing tube time after drainage liquid being clear,the total catheterization time,average daily drainage volume were all significantly different.Conchrsious Double pipe negative pressure drainage for postoperative abdominal drainage can effectively reduce abdominal infection,shorten drainage time,and its effect is very good.
