摘要

目的

探讨聚维酮碘不同停留时间对老年白内障手术结膜囊消毒效果的影响。

方法

选取我院行白内障手术的老年患者396例为研究对象，随机分为长停留组和短停留组，每组198例。长停留组和短停留组患者术前分别使用一次性灌装5%聚维酮碘进行结膜囊消毒3 min和30 s。对2组患者的结膜囊内细菌检出情况、细菌分布和角膜上皮细胞损伤情况进行比较。记录患者消毒后眼部痒感、异物感、眼红和畏光等主观舒适度情况。

结果

在消毒前和消毒后，2组患者细菌检出率比较差异均无统计学意义（

0.05）。在消毒前和消毒后，短停留组检出的细菌均以表皮葡萄球菌占比最高，分别为28.79%和33.33%。消毒后短停留组患者的眼部痒感、异物感、眼红和畏光发生率均显著低于长停留组（

0.05），长停留组患者的角膜上皮细胞损伤率显著高于短停留组（

0.05）。

结论

术前使用一次性灌装5%聚维酮碘进行结膜囊消毒30 s的消毒效果与消毒3 min相当，且其对角膜上皮细胞影响更小，眼部舒适度更高。

Abstract

Objective

To investigate the effect of different residence time of povidone iodine on the disinfection effect of conjunctival sac in senile cataract surgery.

Methods

A total of 396 senile patients who underwent cataract surgery in our hospital were selected and randomly divided into the long-residence group and the short-residence group， with 198 cases in each group. The patients of the long-residence group and the short-residence group were disinfected with a disposable filling 5% povidone iodine on conjunctival sac for 3 minutes and 30 seconds before surgery， respectively. The bacterial detection and bacterial distribution on conjunctival sac，and corneal epithelial cell damage were compared between the two groups. The subjective comfort conditions such as ocular itching， foreign body sensation， erythema， and photophobia after disinfection were recorded.

Results

There was no significant difference in the bacterial detection rate before and after disinfection between the two groups （

0.05）. The most frequently detected bacteria in the short-residence group was Staphylococcus epidermidis，accounting for 28.79% and 33.33% before and after disinfection，respectively.The incidences of ocular itching， foreign body sensation， erythema， and photophobia after disinfection in the short-residence group were significantly lower than those in the long-residence group （

0.05）， while the rate of corneal epithelial cell damage in the long-residence group was significantly higher than that in the short-residence group （

0.05）.

Conclusion

The use of disposable filling 5% povidone iodine for disinfection on conjunctival sac for 30 seconds before surgery can achieve a comparable disinfection effect to disinfection for 3 minutes， which has less effect on corneal epithelial cells， and higher ocular comfort.
