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

Abstract

Abstract Background The 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. Results The 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 0.05). Conclusions DPE 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 registration CTRI, CTRI/2020/08/027060. Registered on 10/08/2020. Trial registered prospectively. CTRI website URL: http://ctri.nic.in
