目的观察两种不同的表面麻醉剂对基础泪液分泌试验(Schirmer I test,SIT)的影响。方法选取我院准分子门诊就诊患者84例(168眼),其中男51例(102眼),女33例(66眼),同一患者左右眼随机分别以5 g·L-1盐酸丙美卡因滴眼液和4g·L-1...目的观察两种不同的表面麻醉剂对基础泪液分泌试验(Schirmer I test,SIT)的影响。方法选取我院准分子门诊就诊患者84例(168眼),其中男51例(102眼),女33例(66眼),同一患者左右眼随机分别以5 g·L-1盐酸丙美卡因滴眼液和4g·L-1盐酸奥布卡因滴眼液1滴单次滴眼,观察滴眼后的眼部刺激症状及结膜充血情况,测量其SIT值,并对结果进行比较分析。结果盐酸丙美卡因组有15眼出现一过性眼部刺激症状,盐酸奥布卡因组有33眼,两组比较差异有统计学意义(P<0.05);盐酸丙美卡因组轻度结膜充血的眼数为54眼,明显多于盐酸奥布卡因组的39眼(P<0.05);盐酸丙美卡因组SIT值为(7.50±5.15)mm,盐酸奥布卡因组为(9.71±5.46)mm,两组间比较差异有统计学意义(P<0.05);盐酸丙美卡因组48眼SIT值小于10 mm,盐酸奥布卡因组为33眼,两者间差异有统计学意义(P<0.05);盐酸丙美卡因组30眼SIT值小于5 mm,盐酸奥布卡因组为21眼,两者间差异无统计学意义(P>0.05)。结论盐酸丙美卡因较盐酸奥布卡因有更好的眼部耐受性,且测量的SIT值短于盐酸奥布卡因组,说明盐酸丙美卡因眼表麻醉效果可能要强于盐酸奥布卡因。展开更多

At the end of surgery, tables were assigned to each patient indicating the degree of pain(0-3) felt during the operation.RESULTS: Thirty-two percent of patients in group 1 declared to have not felt any pain against the 77% of patients in group 2. Fifty-nine percent of patients in group 1 complained about only a slight discomfort against 20% of group 2 patients. Only a small percentage of patients in group 1(5%) admitted severe pain, while no patient in group 2 admitted severe pain. Four patients of group 2 reported an episode of transient amaurosis, lasting several hours after surgery.CONCLUSION: Intracameral administration of lidocaine is a simple and secure method able to increase the analgesia during the cataract surgery, eliminating the discomfort and increasing also the cooperation of the patients during the steps of manipulation.展开更多
