Risk factors of puerperal morbidity in singleton pregnant with cervical cerclage terminating pregnancy after 36 weeks
Objective To investigate the risk factors of puerperal morbidity in singleton pregnant with cervical cerclage who terminate pregnancy after 36 weeks,so as to identify and intervene early,and improve the prognosis.Methods The relevant information of 255 singleton pregnant women who underwent cervical cerclage and gave birth after 36 weeks in Shengjing Hospital Affiliated to China Medical University from January 1,2016 to December 31,2018 were retrospectively collected.According to the incidence of puerperal morbidity,the patients were divided into the puerperal morbidity group(23 cases)and the non-puerperal morbidity group(232 cases).The risk factors of puerperal morbidity were determined by univariate and multivariate Logistic regression analysis.Results The incidence of puerperal morbidity was 9.02％.Multivariate Logistic regression analysis found that removal of cervix suture when labor initiation or after cesarean section after 36 weeks,abdominal delivery,labor transit cesarean section were independent risk factors for puerperal morbidity after cervical cerclage,and prenatal hyperhaemoglobin and vaginal delivery were the protective factors(P＜0.05).Conclusions In clinical work,attention should be paid to the prenatal hemoglobin level of singleton cervical cerclage patients,and the cervical cerclage should be electively removed at 36～37 weeks according to the cervical maturity,and the appropriate delivery mode should be selected based on the patient's condition and fetal intrauterine condition,so as to reduce the occurrence of puerperal morbidity.
