氧化亚氮联合利多卡因行无痛人工流产术280例临床分析

目的: 探讨吸入 50%氧化亚氮 (N2O) 与 50%氧气 (O2 ) 的混合气体联合宫颈注射 2%利多卡因进行无痛人工流产术 (人流术) 的有效性和安全性。方法: 将人流术 580例分为A、B两组。其中A组 280例吸入 50%氧化亚氮 (N2O)与 50%氧气的混合气体联合宫颈注射 2%利多卡因进行无痛人流术, 称为联合组; B组 300例, 不用任何药物, 为对照组, 分析比较两组手术中镇痛效果, 宫口松弛情况, 手术出血量, 人流综合反应。结果: 联合组镇痛完全, 有效率达 97 5%。宫口完全松弛率 97 9%。两组比较有显著性差异 (P<0 05)。结论: 吸入氧化亚氮联合宫颈注射利多卡因进行无痛人流术, 镇痛效果确定, 人流时受术者意识处于朦胧状态, 安静, 无痛苦, 不良反应少, 苏醒快等。

The clinical analysis of N2O combined with lidocaine used in 280 cases of indolence-induced abortion

Objective:To explore the validity and safety of the inhalation of a mixture of 50% N 2O and 50% O 2 combined with 2% lidocaine for cervices injection in indolence-induced abortion Methods:Of 580 cases, 280 cases with the inhalation of a mixture of 50% N 2O and 50% O 2 combined with 2% lidocaine for cervices injection were combined group, then 300 cases without any drugs were control group The analgesic effect, dilation of cervix, bleeding volume and RAAS were compared and analyzed between two groups Results:The analgesic effective rate of inhalation of N 2O and O 2 combined lidocaine injection used in indolence-induced abortion was 97 5% The cervix relaxation rate was 97 9% There was significant difference between two groups ( P <0 05) Conclusion:The inhalation of N 2O and O 2 combined lidocaine injection used in indolence-induced abortion could achieve obvious analgesic effect
