预防白内障术后感染的问题受到关注,文献报告手术后前房吸取液中有29％～43％细菌培养阳性,我们也作了如下检查,现将结果报告于后。材料与方法病员全部为1992年6月至10月住院病例,选择单纯性白内障摘除术者(不含人工晶体植入术),共30例,男16例,女14例,年龄50～70岁,所选病例术前无局部或全身感染性疾病史,眼球无穿孔性外伤史,术中无明显晶体后囊膜破裂史,均无菌操作进行手术。在白内障术毕时,即抽取前房液约0.1ml,滴入血琼脂培养皿上,置入37℃温箱内孵育,每24小时观察一次,3天无菌落出现者为阴性,若有菌落生长,即做分离培养和药敏试验。结果 30例细菌培养中,阳性2例,金黄色葡萄球菌和表面葡萄球菌各1例,药敏试验表明,葡萄球菌对庆大霉素、新霉素极敏感,对青霉素、红霉素、链霉素出现耐受。随访阳性者3个月,未发生眼 Prevention of post-cataract infection is a concern, the literature reported after anterior chamber extract fluid in 29% to 43% of bacterial culture positive, we also made the following examination, the results are reported later. Materials and methods All the patients were hospitalized from June to October in 1992. Thirty patients with simple cataract extraction (excluding intraocular lens implantation) were selected. There were 16 males and 14 females, aged 50-70 years There was no history of local or systemic infectious disease, no history of perforation of the eyeball, no history of clear posterior capsular rupture during the operation, and the patients were aseptically operated. At the end of cataract surgery, about 0.1 ml of the drawn anterior chamber liquid was dripped onto a blood agar plate and incubated in a 37 ° C. incubator. The cells were observed every 24 hours. Negative colonies were found on day 3, Growth, that is, to do isolation and drug susceptibility testing. Results Among the 30 bacterial cultures, 2 were positive, 1 was Staphylococcus aureus and 1 were Staphylococcus aureus respectively. Susceptibility tests showed that Staphylococcus aureus was very sensitive to gentamicin and neomycin, to penicillin, erythromycin, Mycotoxins appear to be tolerant. Follow-up positive for 3 months, no eye occurred
