高负压引流系统对腹部切口愈合的疗效研究

Clinical research on the effect of a high vacuum wound drainage on healing of abdominal incision

目的探讨高负压引流系统对腹部切口愈合的影响。方法回顾性分析行开放手术的126例腹部肿瘤患者,按术后腹部切口是否应用高负压引流系统分为高负压组(63例,术后常规放置皮下高负压引流器)和常规组(63例,单纯行传统换药)。比较两组术后切口引流量、术后疼痛评分、切口不良事件、拆线时间的差异。结果两组术后8天拆线例数比较差异有统计学意义(x^2=27.7,P<0.05);两组患者术后恢复过程中不良事件的发生例数比较差异有统计学意义(x^2=6.95,P<0.05);两组患者术后疼痛评分差异具有统计学意义(x^2=26.36,P<0.05);两组患者术后切口引流量比较差异有统计学意义(t=20.79,P<0.001)。结论高负压引流系统对腹部切口愈合有促进作用,有效的减少了切口不良事件的发生,降低了患者术后疼痛评分,增加了切口引流量、缩短拆线时间,有较高临床应用价值。

Objective To study the efficiencyof a high vacuum wound drainage on healing of ab- dominal incision. Methods A total of 126 patients with abdominal tumor with open surgery were retro- spective analyzed, including 63 cases with high vacuum wound drainage and 63 cases with traditional dressing change. The differences in the volume of drainage, pain scores, adverse events and the time of taking out stitches. Results There were significant differences in numbers of taking out stitches on the 8th day after operation （ χ2 = 27.7, P 〈 0.05 ）, the cases of adverse events in postoperative recovery process （χ2 = 6.95, P 〈 0.05 ）, pain scores （ χ2 = 26.36, P 〈 0.05 ）, and the volume of wound drainage e （ t＇= 20.79,P 〈 0.001 ） between the two groups. Conclusions The high vacuum wound drainage can ef- fectively promote the healing of abdominal incision, reduce the number of adverse events, lower the postop- erative pain scores,increase the volume of drainage and shorten the time of taking out stitches. It has a high clinical value.
