The effects of different timing of labor analgesia on maternal and infant outcomes
Objective To explore the effects of different timing of labor analgesia on maternal and infant outcomes.Methods A total of 120 parturients who underwent painless labor in the obstetrics department were divided into group A,group B and group C according to different timing of labor analgesia,with 40 cases in each group.Epidural labor analgesia(EA)was performed in group A when uterine dilation<2 cm,in group B when uterine dilation was 2-3 cm,and in group C when uterine dilation was>3 cm.The duration of labor,the utilization rate of oxytocin,the rate of cesarean section,and the maternal and infant outcomes of the three groups were compared.Results There was a significant difference in the comparison of the first stage of labor among the three groups(P<0.05);the first stage of labor in group A was(378.46±131.92)min,which was longer than(322.15±117.57)min in group B and(310.39±102.84)min in group C(P<0.05).Comparison of the second stage of labor,third stage of labor,and total stage of labor among the three groups showed no significant difference(P>0.05).The utilization rate of oxytocin and the rate of cesarean section were significantly different among the three groups(P<0.05),and the utilization rate of oxytocin in group C was 62.50%and the rate of cesarean section was 5.00%,which were lower than those in group A(85.00%and 25.00%)and group B(82.50%and 20.00%)(P<0.05).There were no significant differences in 24 h postpartum blood loss and incidence of adverse reactions among the three groups(P>0.05).There were no significant differences in Apgar score at 1,5 and 10 min and incidence of neonatal complications among the three groups(P>0.05).Conclusion When uterine dilation>3 cm,epidural analgesia can effectively shorten the first stage of labor,reduce the utilization rate of oxytocin and the rate of cesarean section,and has little effect on maternal and infant outcomes,so it is a good time to implement epidural analgesia.
