目的 探讨中国人群结膜囊细菌菌属分布规律及主要相关因素,为内眼术前结膜囊无菌化准备提供理论依据。方法 综合分析国内1992～2 0 0 4年正常人结膜囊细菌培养文献,对有相关因素研究的文献进行Meta分析。结果 G+ 球菌、G+ 杆菌、G-杆菌常见,三者合计占97. 85 %。G-球菌少见,偶见真菌。常见菌株有表皮葡萄球菌、金黄色葡萄球菌、微球菌、类白喉杆菌。相关调查因素合并比值比分别为:年龄(1 .89)、性别(1. 36 )、外眼病(2 . 84 )、眼别(1. 0 8)、地区(1. 32 )。结论 对内眼术前结膜囊的无菌化准备,应重视G+ 球菌、G+ 杆菌、G-杆菌等常见菌种以及年龄、性别、有无外眼病等影响因素
Objective To investigate the distribution and main relevant factors of bacterial genus of conjunctival sac in Chinese population and provide theoretical basis for the preparation of aseptic conjunctiva before endophthalmitis. Methods The literature on bacterial culture of normal conjunctival sac in China from 1992 to 2004 was analyzed. Meta-analysis was performed on the literature with related factors. 85%. Results G + cocci, G + bacteria, G-bacteria common, the three together accounted for 97.85%. G-cocci rare, occasionally fungus. Strain common Staphylococcus epidermidis, Staphylococcus aureus, Micrococcus, diphtheria-like bacteria. The relevant ratio of investigation factors were: age (1.89), gender (1.36), external eye disease (2.84), eye (1.08), area (1.32). Conclusion The preparation of aseptic conjunctival sac before intraocular surgery should pay attention to the influence of G + cocci, G + bacilli, G-bacilli and other common bacteria, as well as age, gender,
