目的：探讨利多卡因宫颈旁神经阻滞在人工流产术中的止痛效果。方法：选择１９ 岁～３０ 岁之间，妊娠６ ～９ 周的未产妇２０６ 例。随机分成试验组（ Ⅰ） 和对照组（ Ⅱ） 。Ⅰ组１１７ 例，人流术前行１ ％ 利多卡因宫颈旁神经阻滞。Ⅱ组８９ 例，不给镇痛药，按常规行人工流产术。观察镇痛、宫颈松弛及人工流产综合征反应等情况。结果：试验组与对照组比较，宫颈松弛程度明显提高（ Ｐ ＜ ０ ．０１） ，镇痛效果非常显著（ Ｐ ＜ ０ ．０１） ，人流综合征反应明显减少（ Ｐ ＜ ０ ．０１） ，出血量无明显变化。结论：利多卡因宫颈旁神经阻滞在人工流产术中镇痛效果可靠，宫颈松弛明显，明显减少人流综合征反应，药物作用时间短，毒性小，安全，方法又简单易掌握，值得在临床上广泛应用。
Objective: To investigate the analgesic effect of lidocaine-induced paraesthesic nerve block in artificial abortion. Methods: Choose 19 years old to 30 years old, pregnant 6 to 9 weeks of non-mothers 206 cases. Randomly divided into experimental group (Ⅰ) and control group (Ⅱ). Group Ⅰ 117 cases, abortion 1% lidocaine cervical paralysis before block. Group Ⅱ 89 cases, no analgesics, according to conventional abortion. Observed analgesic, cervical relaxation and induced abortion syndrome and so on. Results: Compared with the control group, the degree of cervix relaxation significantly increased (P <0.01), the analgesic effect was significant (P <0.01), the response to the flow syndrome was significantly reduced (P <0.01), the bleeding No significant change in the amount. Conclusion: The lidocaine-induced cervical para-parahippocampal nerve block has a reliable analgesic effect in abortion. The cervix relaxes obviously and significantly reduces the syndrome of human flow syndrome. The drug has short acting time, low toxicity and safety. The method is simple and easy to grasp. Widely used.
