摘要
目的研究一期缝合的Ⅱ类腹部手术患者术后36-48h起暴露切口对切口感染率的影响。方法215例一期缝合的Ⅱ类腹部手术的患者随机分为两组，实验组于手术后36-48h起除去敷料暴露切口；对照组常规纱布覆盖至拆线日。在术后第1天、第3天、第5天和第7天采集手术切口皮肤表面标本作细菌培养，比较两组菌落数和两组患者住院期间的切口感染率。结果（1）术后第1天、第3天、第5天和第7天，实验组与对照组患者的切口表面细菌菌落数均无统计学差异（P〉0．05）；（2）患者住院期间，两组患者的切口感染率分别为5．65％、8．79％（P〉0．05）。结论手术36-48h后，切口局部防御屏障形成，纱布类敷料不再起到明显减少切口表面细菌数的作用，且对降低切口感染率无明显影响。认为一期缝合的Ⅱ类腹部手术患者术后36-48h后可除去切口敷料。
Objective To study the influence of dressing removal at 36 -48 h after surgery to the rate of wound infection on the surface of type Ⅱ incision of stage-one suture. Methods 215 patients with type Ⅱ incision of stage-one suture were randomly divided into 2 groups. The experimental group was undressing group with dressing removed 36 -48 h after surgery. The control group was dressing group with dressing covered till suture removal. The skin samples were obtained on the first, third, fifth and seventh postoperative day. The bacterial counts on the surface of incision and the rate of wound infection were compared between the 2 groups. Results （ 1 ） There was no statistical difference on the first, third, fifth or seventh postoperative day of the bacterial counts between the undressing group and the dressing group （ P 〉 0. 05）. （2）The incidence of wound infection was 4.84% in the undressing group and 7.70% in the dressing group without significant difference （ P 〉 0. 05 ）. Conclusion The closed primary clean-contaminated wound can be treated without dressing after the first 36 -48 h postoperatively. Since the skin defense barrier is shaped, dressing no longer plays an important role in decreasing bacterial counts on the surface of type Ⅱ incision of stage-one suture or decreasing the rate of wound infection.
