Abstract To explore the effect of epidural double-tube block for labor analgesia of women with full-term pregnancy. Methods: A prospective study was conducted in 352 full-term pregnant women who wanted vaginal trial delivery From January 2021 to December 2022. These women were given labor analgesia and were randomly divide into two groups (176 cases in each group). The women in the observation group were given epidural double-tube block anesthesia, and the women in the control group were given epidural single-tube block anesthesia. The analgesic effect, the cesarean section rate, the labor process, the neonatal score, and the anesthesia complications of the women were compared between the two groups. Results: After labor analgesia, the VAS score of the women in the two groups at the cervix opened to 4cm, at the cervix opened to 10cm, or immediately after fetal delivery had decreased significantly, and which of the women in the observation group (4.20±0.48 points, 4.52±0.54 points, or 4.43±0.62 points) was significantly lower than that (5.81±0.87 points, 6.72±1.20 points, or 6.80±1.14 points) of the women in the control group (all P＜0.05). The rates of natural delivery and the delivery experience satisfaction (81.8% and 97.7%) of the women in the observation group were significantly higher than those (60.2% and 52.3%) of the women in the control group. The rates of the cesarean section and the use of oxytocin (17.1% and 56.8%) of the women in the observation group were significantly lower than those (36.9% and 80.1%) of the women in the control group. The duration of the first stage of labor (570.87±178.52 min), the duration of the second stage of labor (49.64±12.36 min), and the duration of the total labore (625.51±58.44 min) of the women in the observation group were significantly shorter than those (632.35±165.75 min, 62.48±13.29 min, and 712.49±64.87 min) of the women in the control group (all P＜0.05). There were no significant differences in the neonatal Apgar scores at 1, 5 and 10min after birth between the two groups. There were no significant differences in the rates of anesthetic complications, soft birth canal injury, neonatal asphyxia, and neonatal birth trauma of the women between the two groups (P>0.05). The incidences of postpartum hemorrhage (6.8%) and episiotomy (5.7%) of the women in the observation group were significantly lower than those (18.2% and 19.9) of the women in the control group (P＜0.05). Conclusion: Epidural double-tube block anesthesia for labor analgesia of the women with full-term pregnancy has good analgesic effect, which can speed up the labor process, promote the natural delivery, and improve the delivery quality.
