腹腔引流液监测对一次性引流袋更换时间影响探讨

To Investigate the Replacing Time of Drainage Pack for Monitoring the Liquid from Abdominal Cavity

目的探讨腹部手术后腹腔引流一次性引流袋更换的适宜时间。方法对照组30例,每日按照无菌操作方法更换一次性引流袋;观察组40例,于术后当日(置管24 h)、第3日更换一次性引流袋,两组均分别于置管24 h、第3天更换一次性引流袋时,取腹腔引流管内侧与引流袋接头处及引流袋内引流液做细菌培养监测。结果置管24 h,腹腔引流管内侧与引流袋接头处引流液的细菌培养阳性率对照组为3.3%,观察组为2.6%,引流袋内引流液的细菌培养阳性率对照组与观察组均为0;置管3 d腹腔引流管内侧与引流袋接头处引流液的细菌培养阳性率对照组为8.1%,观察组为14.2%,引流袋内引流液细菌培养阳性率对照组为6.7%,观察组为15%。两组比较,均无显著性差异(P>0.05)。结论在临床护理工作中,频繁的更换引流袋容易增加细菌污染的机会,间断更换引流袋并没有提高细菌阳性率,一次性引流袋的更换时间可以每3 d天更换1次。

Objective To investigate more suitable replacing time of drainage pack in the postoperative patients with intraperitoneal drainage.Methods In the control group,the drainage packs of 30 patients were replaced every day.In the experimental group,The drainage packs of 40 patients were replaced on the first day and the third day.The bacterial culture of the liquid which was collected from the connectors of drainage packs and tubes,the drainage packs and the drainage tubes was carried out on the first day and the third day.Results In the control group,The positive rate of bacterial culture of the liquid which was collected from the drainage tubes and the connectors of drainage packs and tubes being carried out on the first day was 3.3%,and it was 2.6% in the experimental group.The positive rate of bacterial culture of the liquid which was collected from the drainage packs being carried out on the first day was zero in the both groups.In the control group,the positive rate of bacterial culture of the liquid which was collected from the drainage tubes and the connectors of drainage packs and tubes being carried out on the third day was 8.1%.It was 14.2% in the experimental group.The positive rate of bacterial culture of the liquid which was collected from the drainage packs being carried out on the third day was 6.7% in the control group,and it was 15%.There is no difference between two groups（P〉0.05）.Conclusion Replacing drainage packs frequently increases the chance bacterial contamination.The bacterial positive rate is not raised with replacing drainage packs for long.The drainage pack can be replaced every 3 days.
