Abstract：ObjectiveTo study the clinical effect of combined spinal epidural anesthesia on labor analgesia during latent phase in parturients.MethodsAltogether 96 primiparas who were treated in our hospital from February 2015 to August 2016 were selected and divided into the control group and the observation group according to use or non-use of labor analgesia,with 48 cases in each group.The control group was not given labor analgesia,while the observation group was treated with combination of subarachnoid block anesthesia (lumbar anesthesia)and epidural anesthesia for labor analgesia.The blood pressure(BP),heart rate(HR),respiratory rate(RR),blood oxygen saturation(SpO2),fetal heart rate(FHR)as well as the stage of labor,mode of delivery and adverse reactions were compared between the two groups.ResultsThe level of BP and HR of the observation group were lower than those of the control group,with statistically significant difference (P＜0.05).There was no statistically significant difference between the level of RR,SpO2and FHR between the two groups(P＞0.05).The latency time of the first stage of labor of the observation group was significantly shorter than that of the control group,with statistically significant difference(P＜0.05).There was no statistical significance in the active phase of the first stage of labor,the second and third stage of labor as well as the mode of delivery between the two groups(P＞0.05).The incidence of adverse reactions was 6.25%(3/48)in the observation group and 0%(0/48)in the control group,without significant difference between the two groups (P＞0.05).ConclusionApplication of combined spinal epidural anesthesia for labor analgesia on maternal latency shows rapid and clear analgesic effect and less adverse reactions,and can effectively shorten the stage of labor to reduce the cesarean section rate,which is worthy of clinical application.
