BackgroundThe dural puncture epidural (DPE) technique has been associated with better sacral analgesia compared with a traditional epidural (EPL) technique in laboring parturients. The aim of this study was to investigate whether DPE with a 27-gauge pencil-point needle compared with a traditional EPL technique produces more rapid bilateral sacral blockade in nulliparous parturients.MethodsPatients were randomized to a DPE or EPL technique. Epidural analgesia in both groups was initiated with ropivacaine 0.1% and sufentanil 0.5 μg/mL (15 mL) and maintained via programmed intermittent epidural boluses. Analgesic blockade was tested bilaterally beginning 10 min after initiation, and then at predefined intervals until delivery. The presence of an S2 blockade at 20 min was the primary outcome.ResultsAmong 108 (54 per group) patients enrolled, bilateral sacral (S2) blockade at 20 min was significantly more common in the DPE than in the EPL group [47 (87%) vs. 23 (43%), absolute risk reduction (ARR) 44%, 95% CI 28 to 60; P < 0.001]. Time to a numeric pain rating scale score (0-10 scale) ≤ 3 (20 [20,30] min in both groups, HR 1.15, 95% CI 0.77 to 1.15; P = 0.50), number of rescue doses [0 (0, 1) vs 0 (0, 1); P 0.08], and presence of bilateral S2 blockade at delivery were not significantly different between groups.ConclusionsThe DPE technique with a 27-gauge pencil-point spinal needle more often provides bilateral sacral blockade at 20 min following block initiation compared with the EPL technique. The time to adequate analgesia and need for supplemental analgesia did not appear to differ between techniques.Copyright © 2024 The Author(s). Published by Elsevier Ltd.. All rights reserved.
