普外科术前聚维酮碘皮肤预消毒的效果研究

Study on the effect of the preoperative pre-disinfection of the skin with the povidone iodine in the general surgery department

目的：探讨使用聚维碘酮进行普外科术前皮肤准备的方法及对不同类型手术切口的效果。方法：选择2013年9月~2014年8月在我院普外科进行手术的740例患者,随机分为观察组372例和对照组368例。对照组采用传统备皮方法,剔除毛发后用软皂清洁皮肤,观察组采用0.5%聚维酮碘预消毒的方法,剔除毛发后用0.5%聚维酮碘涂擦术区皮肤两遍。比较备皮后10 min及24 h两组患者不同切口类型的术区皮肤存菌量及术后切口感染率。结果：观察组感染率低于对照组,差异有统计学意义（P〈0.05）。备皮后10 min及24 h观察组不同部位存菌量低于对照组,差异有统计学意义（P〈0.05）。结论：普外科术前应用0.5%聚维酮碘对术区皮肤预消毒强化了手术常规消毒的效果,保障了患者手术和护理安全性,提高了工作效率,值得推广应用。

Objective：To explore the method of preoperative preparing the skin with the povidone iodine in the general surgery department and the effect of different types of surgical incisions. Methods：We chose 740 patients who received surgeries in the general surgery department in our hospital from Septem- ber,2013 to August 2014 ,and randomly divided into the observation group with 372 cases and the control group with 368 eases. The traditional method of skin preparation was applied in the control group：clean the skin with the soft soap after shaving the hairs ;0.5% povidone iodine pre - disinfection was ap- plied in the observation group：clean the skin twice with the povidone iodine after shaving the hairs compare the amount of bacteria and post - operative wound infection rate of different types of surgical incisions in the two groups 10 min and 24 h after the skin were prepared. Results：The infection rate in the observation group was lower than that in the control group ,and the difference was statistically significant （ P 〈0.05 ）. The amount of bacteria in the observa- tion group was lower than that of the control group 10 rain and 24 h after the skin were prepared, the difference was statistically significant （ P 〈 0.05 ）. Con- clusion ： The preoperative pre - disinfection of the skin with the povidone iodine in the general surgery department strengthens the routine disinfection, en- sures the safety of operation and nursing care, improves the working efficiency, and it is worth promotion and application.
