加温生理盐水在白内障术前结膜囊冲洗中的应用

Application of warmed saline solution for conjunctival sac flushing

目的探讨加温生理盐水在白内障术前结膜囊冲洗中的应用效果。方法白内障手术患者117例(117眼)分为对照组57例(57眼)和实验组60例(60眼)。对照组常规应用生理盐水术前结膜囊冲洗,实验组应用加温生理盐水术前结膜囊冲洗。采用无菌的棉拭子采集结膜囊标本进行细菌培养,对比2组患者结膜囊的充血程度。结果 2组患者结膜囊细菌培养阳性率差异无统计学意义(P>0.05)。冲洗后对照组患者结膜囊充血程度较观察组患者严重(P<0.05)。结论白内障术前运用加温生理盐水冲洗结膜囊,可降低患者不适感。

Objective To investigate the effect of warmed saline solution for conjunctival sac flushing. Methods A total of 117 patients（117 eyes） undergoing cataract surgery were assigned to the control group（n=57） and the study group（n=60）. Normal saline solution for conjunctival sac flushing was carried out in the control group,while the warmed saline solution was applied in the study group. The bacterial culture of conjunctiva sac was conducted,and the conjunctival hyperemia of patients was evaluated after flushing. Results There was no significant difference in positive ratio of bacterial culture between two groups（P〈0.05）. Patients in the control group had more severe conjunctival hyperemia compared with those in the study group（P〈0.05）. Conclusion Warmed saline solution is and safe and comfortable way of conjunctival sac flushing before cataract surgery.
