Comparison of Dural Puncture Epidural Block (DPE) and Combined Spinal-Epidural Anesthesia (CSEA) under Patient-Controlled Epidural Analgesia (PIEB) in Labor Analgesia for Parturients
Abstract：Objective: To investigate the effects of dural puncture epidural block (DPE) combined with patient-controlled epidural analgesia (PIEB) versus combined spinal-epidural anesthesia (CSEA) combined with PIEB in labor analgesia for parturients. Methods: A total of 112 primiparous women who delivered at Zhengzhou Maternal and Child Health Hospital from February 2023 to February 2025 were selected as study subjects and randomly divided into control group and observation group, 56 cases each. The control group received CSEA combined with PIEB, while the observation group received DPE combined with PIEB. The analgesic effects, pain levels at different stages of labor, duration of labor, and incidence of complications were compared between the two groups. Results: The onset time of analgesia in the observation group was shorter than that in the control group, with less ropivacaine usage and fewer effective presses on the analgesia pump, and a lower incidence of breakthrough pain, with statistically significant differences (P<0.05). There was no statistically significant difference in the rescue analgesia rate of ropivacaine between the two groups (P>0.05). At T2 (5 minutes after epidural administration), T3 (30 minutes after epidural administration), T4 (when the cervix was dilated to 8 cm), and T5 (1 hour after delivery), the visual analog scale (VAS) scores of the observation group were lower than those of the control group, with statistically significant differences (P<0.05). The duration of each stage of labor and the total labor duration in the observation group were shorter than those in the control group, with statistically significant differences (P<0.05). The overall complication rate in the observation group was lower than that in the control group, with statistically significant differences (P<0.05). Conclusion: DPE combined with PIEB can shorten the onset time of analgesia, reduce the use of anesthetic drugs, relieve pain in parturients, reduce the incidence of breakthrough pain and complications, and shorten the duration of labor.
