目的 探讨降低白内障术后前房液内细菌培养阳性的方法。方法对８２例（９５眼）白内障患者术中用庆大霉素８ｕｇ／ｍｌ的ＢＳＳ液行前房灌注、术毕取前房液０．１～０．２ｍｌ行细菌学检查。并随意选被研究者的另眼行结膜囊清洗，取结膜囊清洗液或未灭菌的馏水０．２ｍｌ一起参加细菌学检测。结果 前房液培养 ９５眼．阳性 ３眼，阳性率３．１６％；结膜囊清洗液培养３７眼，阳性６眼，阳性率１６．２２％；未灭菌馏水１０份，均为阳性。分离出的细菌主要为表皮葡萄球菌，对庆大霉素等多种抗生素均敏感。结论 用庆大霉素８ｕｇ／ｍｌ的ＢＳＳ 液作前房灌注液，可明显地降低白内障术后前房液内细菌培养的阳性率。有效地抑制术中可能被带入前房的细菌。
Objective To explore a method to reduce the positive bacterial culture in the anterior chamber fluid after cataract surgery. Methods 82 cases (95 eyes) of cataract patients were treated with intravenous injection of gentamicin 8ug / ml BSS solution. And randomly selected by the investigators eye line conjunctival cleaning, take conjunctival sac washing liquid or unsterile water 0.2ml together to participate in bacteriological tests. Results Anterior chamber fluid was cultured in 95 eyes. Positive 3 eyes, the positive rate of 3.16%; 37 conjunctival sac washing fluid, 6 were positive, the positive rate of 16.22%; 10 non-sterile distilled water were positive. Isolated bacteria mainly Staphylococcus epidermidis, gentamicin and other antibiotics are sensitive. Conclusion Gentamicin 8ug / ml BSS solution for the anterior chamber perfusion fluid, can significantly reduce the positive rate of bacterial culture in the anterior chamber after cataract surgery. Effectively inhibit the operation may be brought into the anterior chamber of bacteria.
