摘要 目的探讨降低白内障超声乳化术后感染性眼内炎的预防措施。方法行白内障超声乳化术的患者100例(100眼),随机分为观察组和对照组,各50例(50眼)。所有患者使用加替沙星滴眼液点眼,每2 h 1次,共8次。观察组术前用0.5%聚维酮碘液点眼3 min,对照组用生理盐水冲洗结膜囊。所有患者在应用抗生素点眼前、点眼24 h后及术前予聚维酮碘液点眼或生理盐水冲洗结膜囊后采集结膜囊标本进行细菌培养,在超声乳化手术结束时抽取0.1~0.2 mL前房水进行细菌培养。结果两组加替沙星点眼24 h后结膜囊细菌培养阳性率明显低于用药前(P均<0.05)。观察组予0.5%聚维酮碘液点眼之后细菌培养阳性率与清洗前的阳性率相比,P<0.05。手术结束前两组前房水的培养阳性率为6.0%(6/100,其中表皮葡萄球菌5株),观察组1例,对照组5例,两组相比,P<0.05。结论表皮葡萄球菌是白内障患者结膜囊和术后前房水的主要细菌。白内障术前应用加替沙星滴眼液结合手术开始前使用0.5%聚维酮碘液进行结膜囊冲洗可进一步地降低结膜囊细菌培养阳性率。
