Study on local anaesthesia using Lidocain in induced abortion

目的 评价利多卡因宫颈内口麻醉在人工流产术中的镇痛效果。 方法 人工流产手术者 15 2 5例 ,采用 1.0 %利多卡因各 3ml分别注射在宫颈内口水平 3和 9点处 ,观察 2 m in后无反应再行人工流产手术 ,本组为利多卡因组。对照组 4 0 0例不用任何药物行人工流产术。 结果 利多卡因组镇痛效果 I级 (显效 )为 93.5 % (14 2 6 / 15 2 5 ) , 级 (有效 )为 5 .5 % (84 / 15 2 5 )和 级 (无效 )例为 1.0 % (15 / 15 2 5 ) ,对照组分别为 0 ,19.0 % (76 / 4 0 0 )和 81.0 % (32 4 / 4 0 0 ) ,人工流产综合征的发生率利多卡因组为 1.4 % (2 1/ 15 2 5 ) ,对照组为 16 .0 % (6 5 / 4 0 0 ) ,2组比较 ,差异均有显著性 (P<0 .0 1)。 结论 用 1.0 %利多卡因行宫颈内口麻醉行人工流产术 ,降低了受术者的痛苦 ,减少了人工流产综合征的发生。

Objectives To explore the efficacy of pain relief in induced abortion with Lidocain local application on cervix. Methods 1 525 cases,as a study group,received an injection with 3 ml 1 % Lidocaine at 3 and 9 point of (internal os of) cervix separately at the start of the procedure.Operation started after 2 minutes as long as patients felt no uncomfortable.400 cases.as control group,were operated without any pain relief measures. Results A significant differences in pain scores were found between two groups.The effects on relief of pain in study group were 93.5 % in stage I,5.5 % in stage Ⅱ and 1.0 % in stage Ⅲ respectively.The lower incidence of induced abortion syndrome was 1.4 % in study group vis-a-vis 16.0 % in control group (P<0.01). Conclusion This study demonstrated that the use of Lidocaine on local application improved in pain relief during induced abortion and reduced the incidence of abortion complications.
