Analysis of clinical feasibility of vaginal trial of labor in second pregnancy with scarred uterus after cesarean section
Objective To study the clinical feasibility of vaginal trial of labor in second pregnancy with scarred uterus after cesarean section.Methods 66 women who underwent vaginal trial of labor for a second pregnancy after cesarean section were selected as the scarred group,and 66 women who underwent vaginal trial of labor for a non-scarred uterine pregnancy during the same period were selected as the non-scarred group.Comparison was made on outcome of vaginal trial of labor,duration of labor in women with successful vaginal trial of labor,postpartum hemorrhage,length of hospital stay,occurrence of postpartum residue placenta,occurrence of adverse pregnancy outcomes,and neonatal Apgar score between the two groups.Results There was no statistically significant difference in the success rate of vaginal trial of labor(78.79%VS 84.85%)and cesarean section(21.21%VS 15.15%)between scarred group and non-scarred group(P>0.05).There was no significant difference in the comparison of duration of first,second and third stages of labor and total labor time between the scarred group and the non-scarred group of women who had a successful vaginal trial of labor(P>0.05).In the scarred group,the incidence of postpartum hemorrhage was(210.28±56.36)ml,the length of hospital stay was(3.69±1.62)d and the incidence of postpartum residue placenta was 12.12%,which were not statistically significant when compared with(205.17±49.69)ml,(3.71±1.59)d,and 7.58%(5/66)in the non-scarred group(P>0.05).There was no statistically significant difference in the incidence of adverse pregnancy outcomes between the scarred group(13.64%)and the non-scarred group(10.61%)(P>0.05).Comparison of neonatal Apgar scores at 1,5,and 10 min after birth in the scarred group showed no statistically significant difference(P>0.05).The prognosis of neonates in both groups was good,and no transfer to the neonatal unit was recorded.Conclusion The success rate of vaginal delivery in post-cesarean section pregnant women with scarred uterus is basically the same as that of non-scarred uterus pregnant women,and there is no increase in the duration of labor,postpartum hemorrhage,and the incidence of adverse pregnancy outcomes.It is safe and reliable,which confirms the strong feasibility of vaginal delivery in such women,and has important application value in improving vaginal delivery rate and reducing cesarean section rate.
