Effect of labor induction by oxytocin and the cumulative time of labor in-duction by oxytocin on pregnancy outcomes of women with prolonged pregnancy(41 weeks ≤ gestational weeks<42 weeks)
Objective To investigate the effect of labor induction by oxytocin and the cumulative time of labor induction by oxytocin on pregnancy outcomes of women with prolonged pregnancy(41 weeks≤gestational age<42 weeks).Methods A total of 60 pregnant women with delayed pregnancy admitted to Luoding People's Hospital from June 2022 to May 2023 were selected as the research objects,and they were divided into group A(n=20),group B(n=20)and group C(n=20)by random number table method.The cumulative intravenous infusion time of oxytocin in group A was less than 20 hours,in group B was 20-30 hours,and in group C was more than 30 hours.The delivery mode,neonatal outcome,pregnancy outcome,post-partum hemorrhage and labor time were compared among the three groups.Results The vaginal delivery rate of group A and group B was higher than that of group C,and the fetal distress rate,neonatal asphyxia rate,amniotic fluid contamination rate,cervical lacturing rate and postpartum hemorrhage rate were lower than those of group C,and the differences were statisti-cally significant(P<0.016 7).The amount of postpartum hemorrhage in group C was higher than that in group A and group B,and the differences were statistically significant(P<0.05).The first stage of labor and the total stage of labor in group A and group B were shorter than those in group C,and the differences were statistically significant(P<0.05).Conclusion The relatively safe cumulative time limit of labor induction by oxytocin is<20 h and 20-30 h,and the pregnancy outcome of 20-30 h is better.The cumulative time of labor induction by oxytocin over 30 h will affect the neonatal and pregnancy out-comes.
