摘　　要：目的探讨宫颈注射2%利多卡因进行人工流产术较常规手术的优势。方法选择2011年6月至2012年2月就诊的160例孕妇,将其随机分为无痛组90例和常规组70例,吸宫负压控制于400～500 mmHg(1 mmHg=0.133 kPa),无痛组在宫颈3、9点位置距宫颈外缘约0.5 cm处各注射2%利多卡因2.5 mL,30 s后用扩张器从小号到大号依次顺序通过宫颈,到7号半后行负压吸引术。常规组宫颈或静脉不用任何镇痛药物,即用传统人工流产手术方法。结果无痛组孕妇手术疼痛的总有效率(疼痛0～Ⅱ级)为84.4%(76/90),常规组为50.0%(35/70),无痛组明显高于常规组,差异有统计学意义(P<0.05);无痛组孕妇扩宫效果的有效率为95.6%(86/90),常规组为22.9%(16/70),无痛组明显高于常规组,差异有统计学意义(P<0.01);无痛组孕妇人工流产综合征(PAAS)发生率为2.2%(2/90),常规组为11.4%(8/70),差异有统计学意义(P<0.01);无痛组孕妇出血量为6.74～13.18 mL,常规组为7.55～14.75 mL,差异无统计学意义(P>0.05)。结论宫颈注射2%利多卡因迅速、有效,易于掌握,镇痛效果满意,安全、可靠,故明显提高了手术质量,适合在基层医院推广应用。Objective To investigate the superiority of cervical injection of 2% lidocaine for induced abortion over the routine operation.Methods 160 pregnant women in this hospital from June 2011 to February 2012 were randomly divided into the analgesia group（90 cases） and the routine group（70 cases）.The uterine suction negative pressure was controlled in 400-500 mmHg.In the analgsia group,2% lidocaine was injected at the cervical positions of 3,9 point and about 0.5 cm from the cervical outer margin.After 30 s,the dilator was passed throuth the cervix in sequence from small to large,until the type 7.5 the negative pressure suction was conducted.The routine group did not use analgesic drugs by cervical or intrvenous injection,i.e.used the traditional artificial abortion operation method.Results The total effective rate of operative pain（pain 0-Ⅱ）was 84.4% in the analgesia group and 50.0% in the routine group,the analgesia group was significantly higher than the routine group with statistical difference（P〈0.05）;the effective rate of the uterine dilation was 95.6% in the analgesia group and 22.9% in the routine group,the analgesia group was significantly higher than the routine group with statistical difference（P〈0.01）;the artificial abortion syndrome（AAS） occurrence rate was 2.2% in the analgesia group and 11.4% in the routine group with statistical difference（P〈0.05）;the bleeding volume was（6.74-13.18） mL in the analgesia group and（7.55-14.75）mL in the routine group without statistical difference（P〈0.05）.Conclusion Cervical injection of 2% lidocaine is rapidly effective and easy to master,with satisfactory,safe and reliable analgesia effect,which obviously improves the operation quality and is suitable for promotion and application in basic level hospitals.
