A pilot study comparing dural puncture epidural with 27G Whitacre needle and conventional lumbar epidural labor analgesia

Abstract

BackgroundThe dural puncture epidural (DPE) technique is relatively a new technique of labor analgesia and has been advocated with the advantage of faster onset of pain relief. However, there are differences of opinion regarding the efficacy of the DPE technique and the size of the spinal needle to be used for the DPE. Various studies have suggested that DPE can only be done with a larger gauge of a spinal needle; however, recent studies have variable observations. We have compared the conventional lumbar epidural analgesia and DPE using a 27G pencil-point needle to assess the efficacy of DPE and its possible side effects.ResultsThe time to achieve a 50% reduction in VAS was 7.06 ± 0.79 min in group CLE (n = 15) and 5.0 ± 1.06 min in group DPE (n = 15) (difference of two means was 2.06, 95% CI [1.36, 2.75], t = 5.99, p < 0.0001). The time to achieve VAS < 3 in group CLE was 14.93 ± 1.98 min, and in the group DPE, it was 10.13 ± 1.45 min (difference of two means was 4.8, 95% CI [3.52, 6.09], t = 7.55, p < 0.0001). The mode of delivery, APGAR scores, and side effects were comparable (p > 0.05).ConclusionsDPE provided faster relief of labor pain than the conventional labor epidural analgesia. There were no added side effects by DPE in conventional lumbar epidural analgesia for labor. A 27G Whitacre pencil-point needle can be used for DPE.Trial registrationCTRI, CTRI/2020/08/027060.
