化脓性阑尾炎术后切口感染的预防与处理

Infection factors after appendectomy of purulent appendicitis and its prevention

目的分析化脓性阑尾炎术后切口感染的因素及预防处理。方法回顾性分析我科2008—2011年间治疗的120例化脓性阑尾炎手术患者，对切口感染的相关危险因素进行回归分析。结果化脓性阑尾炎术后患者一期伤口愈合114例（占94％），切口感染7例（占6％），3例行二期缝合。危险因素分析结果显示：合并基础疾病、手术时间、手术方式、腹腔引流物、局部及全身抗厌氧菌药物的使用与切口感染有关，而性别、年龄、切口长度与切口感染无明显相关性。结论选择合适的手术方式，避免长时间的手术操作，正确使用腹腔引流物；合理选用抗生素，积极治疗全身基础疾病可以有效地将切口感染率降低到最低限度。
