Background: Dural puncture epidural (DPE) is a method in which a dural hole is created prior to epidural injection. This study was planned to evaluate whether dural puncture improves onset and duration of labor analgesia when compared to conventional epidural technique. Methods and Materials: Sixty term primigravida parturients of ASA grade I and II were randomly assigned to two groups of 30 each (Group E for conventional epidural and Group DE for dural puncture epidural). In group E, epidural space was identified and 18-gauge multi-orifice catheter was threaded 5 cm into the epidural space. In group DE, dura was punctured using the combines spinal epidural (CSE) spinal needle and epidural catheter threaded as in group E followed by 10 ml of injection of Ropivacaine (0.2%) with 20 mcg of Fentanyl (2 mcg/ml) in fractions of 2.5 ml. Later, Ropivacaine 10 ml was given as a top-up on patient request. Onset, visual analouge scale (VAS), sensory and motor block, haemodynamic variables, duration of analgesia of initial dose were noted along with mode of delivery and the neonatal outcome. Results: Six parturients in group DE achieved adequate analgesia in 5 minutes while none of those in group E (P < 0.05) achieved adequate analgesia. The mean VAS score was 4.97 ± 0.85 in group E and 4.33 ± 0.922 in group DE at 5 min (P < 0.05). Duration of analgesia of initial bolus dose was 99.37 ± 23.175 min in group E and 98.77 ± 24.955 min in group DE (P > 0.05). Conclusions: Both techniques of labor analgesia are efficacious; dural puncture epidural has the potential to fasten onset and improve quality of labor analgesia when compared with conventional epidural technique.
