【摘要】 目的　探讨 1%丁卡因滴眼液采用一次滴眼表面麻醉法测量眼压的效果。方法　采用压陷式眼压计测量眼压 ,按随机方法将 2 0 0例患者分成两组 ,每组 10 0例 ( 2 0 0眼 ) ,观察组采用一次滴眼表面麻醉法 ,表面麻醉 5min后测量 ,对照组采用传统的多次滴眼表面麻醉法 ,15min后测量 ,观察两组表面麻醉效果及并发症情况。结果　两组表面麻醉效果满意。两组并发症经 χ2检验 ,χ2 =7.5 72 ,P <0 .0 1,有显著性差异。结论　一次滴眼表面麻醉法测量眼压效果满意 ,减少并发症 ,优于传统多次滴眼表面麻醉法。更多还原

【Abstract】 ObjectiveTo observe tetracaine eye drip surface anesthesia in examining intraocular pressure.MethodsThe eye pressure was taken with pressing ophthalmotonometer. 200 patients (400 eyes) were evenly put into 2 groups at random: the experimental group and the control group. In the former group, the one-time eye drip was used to conduct surface anesthesia and 5 min later the eye pressure was examined. In the latter, conventional multi-time eye drip to carry out surface anesthesia and 15 min later the pressure was taken. The anesthesia effect and complications were observed.ResultsThe effect of surface anesthesia was satisfactory in both groups. In the experimental group, 1 case complained about itch in one eye but in the control, palpebral edema occurred to 5 cases (7 eyes) and injuries in corneal epithelium to 3 cases (3 eyes). Chi-square test indicated χ 2 =7.572 and P <0.01, showing significance between the groups.ConclusionTetracaine eye drip for surface anesthesia to measure intraocular pressure, the effect is satisfactory and able to reduce complications, which thus is better than conventional multi-time eye drip anesthesia.更多还原
