短节段腰椎后路术中稀释聚维酮碘溶液冲洗术区预防感染的临床效果分析

Analysis of the short-term clinical effect of short segment posterior lumbar operation area of iodophor rinse to prevent infection

目的探讨在短节段（≤2节段）腰椎后路开放手术中应用稀释聚维酮碘溶液冲洗术野对于预防术后伤口感染的效果。方法选取2012年1月至2015年12月我院治疗的所有腰椎后路短节段（≤2节段）减压固定融合术患者164例，应用随机数字表分为两组，其中术中单独应用生理盐水冲洗87例（生理盐水组）；术中应用稀释聚维酮碘溶液冲洗77例（聚维酮碘组），通过随访记录术后3个月不同时间段内两组患者的感染发生率，并对相关数据进行Fisher精确概率法检验。结果生理盐水组感染发生率为8.05%（7/87），聚维酮碘组为1.30%（1/77），两组比较差异有统计学意义（P＝0.04）。结论在短节段（≤2节段）腰椎后路开放手术中应用稀释聚维酮碘溶液冲洗术野对于预防伤口感染有明显效果。

ObjectiveTo investigate the short segment （less than 2 segments） of lumbar posterior open surgery in the application of iodophor rinse operation field for the prevention of wound infection effect.MethodsOne hundred and sixty-four cases patients who underwent all lumbar posterior short segment（less than 2 segments） decompression and fusion in Shunyi District Hospital of Beijing from January 2012 to December 2015 were selected as study objects, and were randomly divided into two groups according to random number table method, including 87 cases of single application of physiological saline（saline group） and 77 cases with diluted iodophor rinse liquid during the operation（diluted iodophor group）. The incidence of infection in patients with different irrigation patterns during 3 months after the operation was followed up, and the results were analyzed by Fisher exact probability method.ResultsThe infection rate of saline group was 8.05%（7/87）, 1.30%（1/77） of iodophor group, there was significant difference between two groups（P=0.04）.ConclusionThe application of iodophor rinse operation field for the prevention of wound infection has obvious effect on lumbar posterior open surgery.
