AbstractThis study aimed to investigate the effect of dural puncture epidural (DPE) combined with small-dose lidocaine for labor analgesia. Parturients were randomly divided into epidural anesthesia (EA), DPE1, and DPE2 groups. In the EA group, 5 mL of 1% lidocaine was administered via conventional L2-L3 puncture catheterization; in the DPE1 group, epidural drug was administered after catheterization using the DPE technique; in the DPE2 group, epidural puncture drug was administered through the epidural puncture needle before catheterization using the DPE technique. The primary outcome was the onset time of analgesia. The secondary outcomes included the numerical rating scale (NRS) scores during uterine contraction before bolus injection of experimental dose (T0) and the second time (T1), the fifth time (T2) and the tenth time (T3) after bolus injection of experimental dose; NRS scores at the second stage of labor (T4) and during perineal suture (T5); operation time of anesthesia; puncture related complications; anesthesia related complications; delivery outcome; use of local anesthesia during vaginal suture; and Apgar score of the neonates. There were 115 women included. The onset time in the DPE2 group was markedly shorter than in the EA and DPE1 groups (P < .001). The NRS scores in the DEP2 group at T1 and T4 were significantly lower than in the EA and DEP1 groups (P < .001). The overall incidence of puncture related complications in the DEP1 and DEP2 groups was markedly higher than in the EA group (P < .05). In dural puncture epidural analgesia, when the experimental dose was injected directly through the epidural puncture needle, the onset time was shorter and the analgesic effect was better as compared to the injection of test dose after inserting the epidural catheter.Copyright © 2023 the Author(s).
