目的观察笑气配合利多卡因在人工流产术中的应用效果。方法选择妊娠6～8周要求人工流产的初孕妇256例,随机分为两组,观察组与对照组各128例,观察组在人工流产术中吸入医用镇痛气体(氧气、笑气及其他医用气体)。消毒外阴、阴道、宫颈,以无菌棉签浸2%盐酸利多卡因1ml左右,插入宫颈管内1～2min取出,然后行人工流产术;对照组所用药物为2%盐酸利多卡因,方法同观察组。结果观察组镇痛效果明显优于对照组。宫颈口松弛:观察组为97.65%,对照组为69.53%,人工流产综合征发生率:观察组占2.34%,对照组占9.38%,术中平均出血量:观察组为(16.42±13.31)ml,对照组为(20.45±17.38)ml。结论笑气配合利多卡因用于人工流产,镇痛效果观察组明显优于对照组,观察组与对照组宫颈口松弛、人工流产综合征发生率差异有统计学意义(P<0.05),术中平均出血量无明显差异。
Objective To observe the effect of using laughing gas with lidocaine in artificial abortion. Methods Two hundred and sixty-eight first-trimester pregnant women requiring artificial abortion from 6 weeks to 8 weeks of gestation were randomly divided into two groups: observation group and control group, 128 cases each. The observation group received medical analgesia (oxygen, nitrous oxide and other Medical gas). Disinfection of the vulva, vagina, cervix, sterile cotton swab dip 2% lidocaine hydrochloride 1ml about 1 ~ 2min inserted into the cervical canal removed, and then artificial abortion; control group used 2% lidocaine hydrochloride, the same observation group. Results The observation group analgesic effect was significantly better than the control group. Cervical relaxation: the observation group was 97.65%, the control group was 69.53%, the incidence of induced abortion syndrome: the observation group accounted for 2.34%, the control group accounted for 9.38%, intraoperative blood loss: the observation group was (16.42 ± 13.31) ml , The control group was (20.45 ± 17.38) ml. Conclusion Laughter of lidocaine combined with lidocaine was used in induced abortion. Analgesic effect was better in the observation group than in the control group. The incidence of cervical relaxation and abortion syndrome in the observation group and the control group were significantly different (P <0.05) The average amount of bleeding in the no significant difference.
