白内障术前结膜囊细菌培养影响因素分析

目的:研究影响白内障人工晶状体植入术前结膜囊细菌培养阳性率的主要影响因素。方法:对2010-12/2012-12在本院住院行白内障人工晶状体植入术的老年患者,分别于入院时、滴眼药水后、术眼准备后3个时间点,采集结膜囊标本进行细菌培养,并将培养结果与年龄、性别、眼别、职业、滴眼天数、干预方法等因素相关关系进行比较分析。结果:年龄、性别、干预方法等因素对结膜囊细菌培养阳性率有显著性关联,职业、眼别、术前滴眼天数对结膜囊细菌培养结果影响不大。结论:影响结膜囊细菌培养因素有患者自身因素,也有外部因素,干预方法对结膜囊细菌培养阳性率影响至关重要,应引起重视。

Analysis of the influence factor on the bacterial culture of conjunctival sac before cataract

AIM: To investigate the main factors that affecting the positive rate of bacterial culture before the intraocular lens implantation.

METHODS:Conjunctival sac specimen form senile patients, who received cataract crystal implantation from December 2010 to December 2012 in our hospital, were collected and cultivated at the following 3 time points: on admission day, after the eye-drops and after the surgical eye preparation. Afterwards, a comparative analysis was made in terms based on of the following factors: age, gender, dominant eye, occupation, days for eye-drops as well as the intervention techniques.

RESULTS: Factors such as age, gender, intervention technique were significantly related with the rate of bacterial culture, while factors such as occupation, dominant eye and days for pre-operative eye-drops had few effects on the final results.

CONCLUSION: There are both internal factors and external factors affecting the bacterial culture. Inconjunctival sac intervention techniques play a crucial role in the bacterial culture in conjunctival sac, which deserves more attention.
