目的减轻人流时负压吸引的疼痛,缩短手术时间,预防人工流产反应综合征(RAAS)的发生。方法妊娠6～12周行人工流产孕妇402例,随机分为观察组214例,对照组188例。观察组将2%利多卡因5ml加阿托品0.5mg混合,分别在宫颈6、12点或3、9点处相当于宫颈内口水平呈35°进针,各注入药液半量,1～2min后行吸宫术。对照组按传统人工流产方法施术。结果观察组镇痛效果显效89.35%,有效7.14%,无效2.31%,恶心、呕吐甚至人工流产综合症的发生率比对照组明显降低(P<0.01)。结论利多卡因阿托品宫颈阻滞麻醉在人流术中,对宫颈平滑肌有良好的松弛作用,大大缩短了扩宫时间,且不增加出血量,值得推广应用。

The Application of Paracervical Block with Lidocaine and Atropine in Artificial Abortion

Objective:To alleviate the pain caused by negative pressure d uring suction curettage,reduce operation time and prevent the occurrence of RAAS .Methods:Four hundred and two gravidas in their 6~12 weeks pregnancy,who came to the outpatient of our hospital to have artificial abortion,were divided randoml y into two groups:214 in observation group and 188 in control group.In the obser vation group,2% lidocaine 5ml and atropine 0.5 mg were mixed together,and were i njected into the cervix at the points of 6,12 oclock or 3,9 oclock at the level of intracervical os with the needle at an angle of 350.Half amount of the drugs was injected into each points.Suction curettage was applied.Results:The analgesi c effect in the observation group was satisfactory.The incidence of nausea and v omiting,even RAAS was dramatically decreased.The significantly effective rate wa s 89.35%,the effective rate was 7.41% and no effective rate was 2.31%.There was significantly difference between the two groups(P<0.01).Conclusion:The para cervical block with lidocaine and atropine has good effects on the relaxation of cervical smooth muscle and largely reduces the time of cervical dilation,which result in a short operation time and less blood loss.
