摘要
目的分析老年患者白内障围术期眼部感染的病原菌来源、构成及特点,探讨与之相对应的感染预防措施。方法回顾性分析我院2014年3月-2015年2月80眼(80例)老年(≥60岁)患者白内障围术期眼部感染的临床资料及感染控制措施的应用情况。结果 80例术前睑缘细菌培养阳性率(65%)高于结膜囊(37.5%),细菌构成基本相同,其中最常见的为G+球菌,以表皮葡萄球菌为主。局部用0.5%左氧氟沙星滴眼液后,睑缘及结膜囊细菌培养阳性率(40%/20%)较用药前有明显下降;联合应用聚维酮碘溶液、无菌眼科手术贴膜及妥布霉素溶液后,睑缘及结膜囊细菌培养均为阴性;手术结束撕除无菌手术贴膜后,睑缘细菌培养7例阳性且均为表皮葡萄球菌;手术结束时前房水及超声乳化机受水袋液体细菌培养均为阴性。结论从感染源着手进行白内障围术期的干预,是减少老年白内障手术感染的有效手段。
Objective To analyze the source and constitution of pathogens causing ocular infection in elderly patients during perioperative period of cataract surgery and explore its relative preventive measures. Methods In this retrospective study conducted in Chinese PLA General Hospital, clinical data about 80 eyes（80 patients aged ≥ 60 years） were collected from March 2014 to February 2015 and analyzed by SPSS 20.0 statistical software. Results The positive rate of bacteria culture was significantly higher in palpebral magin（65%） than conjunctival sac（37.5%）, while there were tiny differences in the components of pathogens in two sites with G＋ coccus as the most common seen bacteria; after the use of 0.5% levofloxacin eye drops, the positive rate of bacteria culture in palpebral magin and conjunctival sac decreased significantly（40%/20%）. With the application of PVP-iodine solution, surgical membrane and tobramycin solution, the bacteria culture turned to be negative. At the end of surgery, there were 7 cases with palpebral magin cultured to be positive, all of which was S.epidermidis, while it was found to be negative in the bacteria culture of anterior aqueous fluid. Conclusion The elderly patients are inferred to have a higher risk of infection. Taking control of source of infection reasonably is an effective way to decrease the incidence of infections.
