持续低流量生理盐水冲洗对持续负压封闭引流技术堵管情况的影响

摘要

目的：探讨持续低流量生理盐水冲洗对留置负压封闭引流技术（VSD）管道患者堵管情况的影响。方法：选择2014年1～5月在我科住院并使用 VSD 治疗软组织损伤的患者50例，随机分为对照组20例和观察组30例，观察组使用生理盐水以1 ml ／min 的速度持续低流量冲洗。对照组采用常规 VSD 引流。对两组患者的堵管情况、导管留置时间、护理导管与置管耗费时间、VSD 耗材费用进行观察及比较。结果：观察组发生堵管情况、留置管道时间、护理管道时间、置管耗费时间、VSD 耗材费用均少于对照组，差异有统计学意义（P 均＜0．05）。结论：持续低流量冲洗 VSD 管道，能有效的避免管道堵塞。%Objective:To investigate continuous low flow saline impact on retention vacuum sealing drainage (VSD) patients pipeline plugging conditions. Methods:From January to May 2014 in our hospital and using VSD treatment of soft tissue injuries of 50 patients were randomly divided into a control group of 20 cases and 30 cases of the observation group,the observation group using saline to 1 ml /min rate of sustained low -flow water.VSD control group with conventional drainage.For plugging in the two groups of patients,catheter time,catheters and catheter care takes time,VSD supplies costs were observed and compared.Results:The occurrence of plugging,the indwelling pipeline time,nursing pipeline time,catheterization time consuming,VSD supplies costs were less than the control group,the difference was statistically significant (P <0.05).Conclusion:The continuous low flow flush VSD pipeline, which can effec-tively prevent pipeline blockage.
