粘贴式负压冲吸器在治疗结直肠术后切口感染中的应用研究

Adhesive negative pressure suction apparatus in treatment of the wound infection after colorectal surgery

目的探讨应用粘贴式负压冲吸器治疗结直肠术后切口感染的效果。方法将2010年1月-2011年11月南京军区福州总医院普通外科收治的48例结直肠手术后m现切口感染的患者，按照抽签随机分组的方法，随机分为实验组和对照组，实验组24例，采用粘贴式负压冲吸器治疗；对照组24例，采用传统处理方法治疗。对比2种方法的人均伤口处理时间、换药次数和换药总费用。结果实验组白开始处理感染切口至二期缝合所需要的人均伤口处理时间（6．12±1．19）d短于对照组（8．54±2．98）d，差异有统计学意义（P〈0．05），人均换药次数[（1．44±0．51）次]明显少于埘照组[（9．42±2．92）次]，差异有统计学意义（P〈0．01），人均换药总费用也少于对照组，差异有统计学意义（P〈0．05）。结论应用粘贴式负乐冲口发器治疗结直肠术后切口感染，能缩短伤口处理时间，减少了换药次数和换药总费用，具有较高的临床应用价值。

Objective To investigate the efficacy of adhesive negative pressure suction apparatus in treatment of wound infection after colorectal surgery. Methods From January 2010 to November 2011 , consecutive patients with wound infection after colorectal surgery were randomized to the experimental group （n = 24） and the control group （ u = 24）. The patients in experimental group were treated with the adhesive negative pressure suction appara- tus. The patients in the control group were treated with traditional wound therapy. The results of treatment were evaluated. Results Time from debriding the wound infection to secondary suture was significantly shorter in patients of the experimental group （P 〈 0.05 ）. The total number of dressing changes was very significantly less in patients of the experimental group （P 〈 0.01 ）. The total cost of dressing in experimental group was significantly Jess than the control group （P 〈 0.05）. Conclusions The application of adhesive negative pressure suction apparatus in treatment of the wound infection after colorectal surgery can shorten the wound processing time, reduce the number of dressing changes and the total cost of dressing, thus has a high clinical value.
