Abstract：Objective:To study the clinical effectiveness of epidural labor analgesia by ultrasound-guided median approach.Methods:100 maternal cases admitted to the hospital from January 2020 to December 2021 were selected for the study and were divided into a control group(n=50)and a study group(n=50)using the random number table method.Epidural labor analgesia and epidural labor analgesia by ultrasound-guided median approach were administered respectively.The duration of labor,mode of de-livery,pain level,2-h postpartum bleeding,neonatal 1 min Apgar score,satisfaction and adverse effects were observed and com-pared between the groups.Results:The first stage of labor was significantly longer in the study group than in the control group,and the second stage of labor was significantly longer than in the control group,with statistically significant differences(t=2.758,8.653,P＜0.05).The composition ratio of the number of transvaginal deliveries was higher in the study group than in the control group,and the composition ratio of the number of cesarean deliveries was lower than in the control group,with statistically signifi-cant differences(χ2=6.139,4.574,P＜0.05).The results of the comparison of the observations at full opening of the uterus in both groups and the comparison of the observations after delivery showed that the VAS scores were significantly lower in the study group than in the control group,with statistically significant differences(t=17.455,8.384,P＜0.05).The results of the comparison of ma-ternal delivery satisfaction observations between the two groups showed that the study group scored significantly higher than the control group,and the difference was statistically significant(t=8.564,P＜0.05).Conclusion:Although epidural labor analgesia by ultrasound-guided median approach may prolong the first and second stage of labor to a certain extent,it can further reduce the rate of cesarean section and labor pain,and has no adverse effects on postpartum hemorrhage and the newborn,with fewer adverse effects,which is more conducive to improving labor satisfaction.
