外来医疗器械不同清洗方法与医院感染分析

Correlation between cleaning of foreign medical instruments and incidence of nosocomial infections

目的探讨外来器械不同清洗方式与手术患者术后发生医院感染的关系。方法外来器械分别采取供应商清洗、消毒供应中心人员将外来器械直接机器清洗及工作人员采取手工预洗+超声酶洗+上机洗3种不同清洗方式处理的外来器械,经灭菌后使用,对术后患者感染发生率进行对比。结果采取手工预洗+超声酶洗+上机洗方式处理外来器械,术后感染率最低0.71%,直接上机清洗处理的外来器械,术后感染率稍高1.68%,由供应商清洗处理的外来器械,术后患者感染率最高3.14%,差异有统计学意义(P<0.05)。结论外来器械采取手工预洗+超声酶洗+上机洗方法为最优化,对提高清洗质量、确保灭菌效果、降低医院感染是一重要手段。

OBJECTIVE To explore the correlation between the different cleaning methods of foreign medical instruments and the incidence of postoperative nosocomial infections. METHODS The foreign instruments were respectively cleaned by the suppliers, the machine, and hand washing plus ultrasonic enzyme washing and machine, then the instruments were used after sterilization, and the incidence of postoperative nosocomial infections was observed. RESULTS The incidence rate of postoperative nosocomial infections was the lowest （0.71%） after the instruments were cleaned by hand washing plus ultrasonic enzyme washing and machine, 1.68% after the machine cleaning, 3.14% after the instruments were cleaned by the suppliers, the difference was statistically significant （P〈0.05）. CONCLUSION The hand washing plus ultrasonic enzyme washing and machine is the optimal method for the cleaning of foreign medical instruments and is an effective way to improve the cleaning quality, ensure the sterilization effect, and reduce the incidence of nosocomial infections.
