Application effect of combined spinal epidural anesthesia during latent period in vaginal delivery of primiparous women
Objective To observe the application effect of combined spinal epidural anesthesia during latent period in vaginal delivery of primiparous women.Methods Totally 98 primiparous women who delivered vaginally in our hospital from January 2021 to December 2022 were selected and divided into two groups using a random number table method.The control group(n=49)received combined spinal epidural anesthesia during the active phase,while the study group(n=49)received combined spinal epidural anesthesia during the latent phase.Analgesic effect,labor process time,Apgar score of newborn,blood gas analysis results of umbilical artery,maternal complications and postpartum depression were compared.Results There was no statistically significant difference in visual analogue scale(VAS)scores be-tween the study group and the control group before analgesia and during 7-8cm dilation of the cervix(P＞0.05).The VAS scores at 5 minutes,10 minutes,15 minutes,and 10cm dilation of the cervix were lower than those of the control group(P＜0.05).The time of the first stage of labor in the study group was shorter than that in the control group(P＜0.05),while the time of the second stage of labor,Apgar score at 1 min of birth,Apgar score at 5 min of birth,umbilical artery blood gas analysis indicators,and the total incidence of maternal complications were not significantly dif-ferent from those in the control group(P＞0.05).The incidence of depression at 7 days postpartum and 42 days post-partum in the study group was lower than that in the control group(P＜0.05).Conclusion The combined spinal epi-dural anesthesia has a definite analgesic effect in the incubation period during vaginal delivery of primipara,which can shorten the first stage of labor,reduce the incidence of postpartum depression,have no significant impact on Apgar score of newborns,umbilical artery blood gas analysis results,and do not increase the incidence of maternal complications.
