宫颈冷刀锥切术对患者妊娠结局影响因素分析

目的 探讨宫颈冷刀锥切术对患者妊娠结局的影响和临床处理方案效果.方法 选择2014年1月至2017年1月行宫颈冷刀锥切术的患者进行电话随访,筛选出有生育要求的患者进一步随访,随访患者的一般情况及妊娠情况至2018年6月.对患者的手术情况,妊娠情况、分娩孕周、不良妊娠结局及新生儿情况等问题进行回顾性分析.结果 流产发生率、羊水异常、胎儿宫内窘迫和胎盘异常发生率差异与宫颈锥切高度无关,宫颈锥切高度≥20mm组的早产率为23.5%,胎膜早破发生率为29.4%,低出生体重儿发生率为25%,高于其他两组(P<0.05).结论 宫颈锥切高度≥20mm是导致患者早产和低出生体重儿的重要原因,宫颈锥切术对流产发生率无明显影响,但是增加了剖宫产率,可能是与社会心理因素相关.

Objective To investigate the effect of cold knife conization of cervix on pregnancy outcome and the effect of clinical treatment.Methods From January 2014 to January 2017,patients underwent cervical cold knife conization were followed up by telephone,and patients with fertility requirements were screened out for further follow-up.The general situation and pregnancy status of patients were followed up until June 2018.The operation,pregnancy,gestational weeks of delivery,adverse pregnancy outcomes and neonatal conditions of the patients were analyzed retrospectively.Results The incidence of abortion,amniotic fluid abnormality,fetal distress and placenta abnormality was not related to the cervical conization height.The premature delivery rate was 23.5%,the premature rupture rate of membranes was 29.4%,and the incidence of low birth weight infants was 25%,which was higher than the other two groups(P<0.05).Conclusion The height of cervical conization(>20mm)is an important cause of premature birth and low birth weight infants.Cervical conization has no significant effect on the incidence of abortion,but increases the rate of cesarean section,which may be related to psychosocial factors.
