为观察比较宫颈分神经阻滞麻醉和宫腔、宫颈管表面麻醉效果。将170例到我院门诊行人工流产术患者随机分为A、B两组，A组120例，行2％利多卡因5ml宫颈旁神经阻滞麻醉，B组50例，行2％利多卡因5ml宫颈、宫颈管表面麻醉。观察两组人流综合征发生率、宫颈松驰情况，止痛效果。结果表明，A组人流综合征发生率低，宫颈松弛好，止痛效果好，均较B组有显著性差异。提示，利多卡因宫颈分神经阻滞效果优于宫腔，宫颈管表面麻醉。
To observe and compare cervical nerve block anesthesia and uterine cervix surface anesthesia. 170 patients who came to our hospital for artificial abortion were randomly divided into A and B groups, 120 cases in group A and 2 ml lidocaine 5ml paraquiar nerve block were anesthetized. Group B, 50 cases were treated with 2% lidocaine Due to 5ml cervical, cervical canal surface anesthesia. Two groups were observed incidence of flow syndrome, cervical relaxation, analgesic effect. The results showed that A group of low incidence of flow syndrome, cervical relaxation, analgesic effect, compared with the B group had significant differences. Tip, lidocaine cervical nerve block superior to the uterine cavity, cervical surface anesthesia.
