负压引流管在腹部急诊手术中预防切口感染的应用

The effect of negative pressure drainage tube for the prevention of incision infection in emergency abdominal surgery

目的探讨在腹部急诊手术中,放置切口皮下负压引流管对切口感染的预防作用。方法回顾分析本科145例腹部急诊手术患者的切口愈合情况,其中67例切口皮下放置负压引流管的患者作为实验组,78例无负压引流管的患者作为对照组,比较2组切口感染率、甲级愈合率、住院时间的差异。结果实验组67例患者中切口感染1例(1.49%),对照组78例患者中切口感染7例(8.97%),感染率差异有统计学意义(P<0.05);实验组66例切口愈合者中甲级愈合63例(95.45%),对照组71例切口愈合者中甲级愈合58例(81.69%),甲级愈合率差异有统计学意义(P<0.05);实验组平均住院时间(14.82±8.73)天,对照组(19.13±13.11)天,住院天数差异有统计学意义(P<0.05)。结论皮下负压引流管可以有效减少腹部急诊手术术后切口感染,促进切口甲级愈合,缩短住院时间。

Objective To investigate the effect of placing negative pressure drainage tube for the prevention of incision infection in emergency abdominal surgery.Method A retrospective analysis for incision healing of 145 emergency abdominal surgery patients was undertaken, including 67 patients with subcutaneous negative pressure drainage tube as the experimental group and 78 patients without the tube as the control group. The incidence rates of incision infection, grade-A healing and the length of hospital stay were analyzed.Result There was one case incision infection in the experimental group （incidence rate 1.49%） compared with seven cases in the control group （incidence rate 8.97%）, showing statistically significant difference （P〈0.05）.The number of grade-A healing included in the incision healing patients in the experimental group was 63（incidence rate 95.45%）, compared with 58（incidence rate 81.69%） in the control group, also showing statistically significant difference （P〈0.05）.The average length of hospital stay was （14.82±8.73）days for the experimental group, compared with（19.13±13.11）days for the control group, still showing statistically significant difference （P〈0.05）.Conclusion Placing subcutaneous suction drainage tube can effectively decrease the postoperative incision infection rate, promote incision healing and reduce the length of hospital stay for emergency abdominal surgery patients.
