目的

评价术中冲洗在预防阑尾切口感染的作用。

方法

600例穿孔性阑尾炎随机分成三组。腹腔冲洗组189例(A组)、腹腔、腹壁肌冲洗组202例(B组)、腹腔、腹壁肌和皮肤三个层面冲洗组209例(C组)，冲洗均用生理盐水及甲硝唑。术后观察三组切口感染情况。

结果

切口感染率A组为18.52% (35/189)，B组为7.43%(15/202)，C组为3.35%(7/209)，三组差异有显著性（P<0.05）。

结论

腹腔、腹壁肌和皮肤三个层面清洁能显著降低阑尾切口感染率。

Objective

To evaluate the value of irrigating in operation to prevent infection of appendix incisional wound.

Methods

600 cases of perforating appendicitis divided into three groups in random：abdominal cavity irrigating(A group,189 cases),abdominal cavity and abdominalwallirrigating(B group,202 cases),abdominalcavity,abdominalwall and skin three layers irrigating(C group,209 cases).In all cases irrigation liquid used normal saline and arilin.Postoperative infection of incisional wound condition was observed.

Results

Infection rate of incisional wound is 18.52%(35/189)in A group，7.43%(15/202)in B group，3.35%/(7/209)in C group.Comparing three groups the difference is significant（P<0.05）.

Conclusion

Abdominal cavity,abdominal wall and skin three layers are all cleaned,which can reduce infection rate of incisional wound.
