摘　　要：目的探讨盐酸丁卡因胶浆在泪道探通和扩张术中进行局部麻醉的效果。方法将100例已行泪道激光治疗或泪道激光联合泪道置管治疗后已拔管的泪道阻塞患者随机分成对照组和观察组。对照组患者在泪道探通时，先用9号泪道探针探通泪道，留针20min，更换12号泪道扩张针，再留针20min。观察组患者在泪道探通时，先用9号泪道探针探通泪道，边探通边注入适量盐酸丁卡因胶浆，留针20分钟min后，逆行退针，边退针边注入适量盐酸丁卡因胶浆，更换12号泪道扩张针，再留针20min。记录两组患者在行泪道探通和扩张术中的疼痛程度。结果对照组患者的疼痛发生率为90％，观察组患者的疼痛发生率为28％。结论盐酸丁卡因胶浆可以有效减轻患者在泪道探通和扩张术中的疼痛，值得推广。Objective To investigate local anesthetic effect of tetracaine hydrochloride jelly in probing and dilating lacrimal duct surgery.Methods 100 patients of lacrimal duct obstruction who have been given laser surgeries or tube implantation supplemented laser surgeries with extubation were randomly divide into control and observation group.For control group,we first used lacrimal probe No.9 and left the probe in the duct for 20 rain,and then used lacrimal dilation probe No. 12 and left the probe for 20 min.For observation group,we injected appropriate amount of tetracaine hydrochloride jelly while probing with lacrimal probe No.9;left the probe in the duct for 20 min and then injected appropriate amount of tetracaine hydrochloride jelly while retrograding the probe; we used lacrimal dilation probe No. 12 and left the probe for 20 min.We recorded the degree of pain of the two groups in probing and dilating lacrimal duct surgeries.Results The pain incidence in the control group is 90%, while that in the observed group is 28%.Conclusion Tetracaine hydrochloride jelly can effectively relieve patient＇s pain in probing and dilating lacrimal duct surgery and is worth popularizing.
