75%乙醇与0.5%碘伏眼部消毒后睑缘存菌的调查

Carrier State of Lid Margins after Eyes Area Disinfection by 75% Alcohol and 0.5% Iodine

目的了解75%乙醇与0.5%碘伏两种不同消毒方法眼部消毒后睑缘存菌状态,对比不同消毒方法眼部消毒效果,探讨采用碘伏消毒法作为眼科手术眼部消毒方法的可行性。方法以38例实施眼科手术的患者为研究对象,取手术侧眼为对照组采用75%乙醇进行外眼皮肤常规消毒,取对侧眼为实验组采用0.5%碘伏进行外眼皮肤消毒,消毒3 min后分别进行两眼睑缘细菌学培养。结果实验组合格率为81.58%,对照组合格率为60.53%;统计学分析显示,两组睑缘存菌状态差异有统计学意义(P<0.05),实验组优于对照组。结论采用0.5%碘伏消毒眼部皮肤范围可达睑缘,此方法可有效控制眼部术后感染、保证眼部消毒效果。

OBJECTIVE To investigate the carrier state of lid margins after eyes area disinfection by 75 % alcohol and 0. 5 % iodine and to compare the effect of different disinfectants, so we will know whether 0. 5 % iodine can be used for eyes area disinfection. METHODS Thirty eight patients （76 eyes） from our hospital in March-May 2005 were analyzed. The operated eyes area as control group were disinfected by 75% alcohol- the traditional disinfection method. The contralateral eyes area without operation as experimental group were disinfected by 0. 5 % iodine. Lid margins samples were obtained for culture after 3 minutes. RESULTS The qualification rate was 81.58% in the experimental group whereas 60. 53% in the control group（P〈0. 05）. The qualification rate was higher in the experimental group than in the control group. CONCLUSIONS The 0. 5 % iodine, whose disinfection range can reach the lid margins and get effective disinfection, can be used in eye area disinfection.
