报道4组老年人人工晶体植入术前的结膜囊细菌状况。第1组术前正常结膜囊阳性率为45.7%;第2组术日结膜囊组阳性率为19.2%;第3组切口前结膜囊阳性率为19.2%;第4组结膜充血组阳性率为53.1%,与前3组比较差异显著(P<0.05)。前三组菌株多数是葡萄球菌结膜34例次(80.9%),表皮葡萄球菌最多22例(52.4%),金黄色葡萄球菌次之9例(21.4%)。结膜充血组菌种多,仍然是葡萄球菌较多。多数菌株对庆大霉素、先锋霉素和氟哌酸敏感。术前结膜囊有菌者术后眼内反应较重。
Reported 4 groups of elderly patients with intraocular lens implantation before conjunctival bacteria. The positive rate of normal conjunctival sac in group 1 was 45.7%. The positive rate of conjunctival sac in group 2 was 19.2%. The positive rate of conjunctival sac in group 3 was 19.2%. The positive rate of conjunctival hyperemia group in group 4 was 53.1%, which was significantly different from the former three groups (P <0.05). Staphylococcus aureus conjunctiva 34 cases (80.9%), Staphylococcus epidermidis 22 cases (52.4%) and Staphylococcus aureus 9 cases (21.4%). Conjunctival congestion group of bacteria and more staphylococcus is still more. Most strains are sensitive to gentamicin, cephamycin and norfloxacin. Preoperative conjunctival sac bacteria intraocular reaction after severe.
