Comparison of epidural, combined spinal epidural, and dural puncture epidural techniques for labor analgesia

Background: Lumbar epidural analgesia is a safe, effective, and beneficial technique for both the parturient and the fetus. Dural puncture epidural has been claimed to be better than combined spinal epidural and epidural techniques by many. We undertook this study to compare the three techniques regarding duration, quality of analgesia, and side effects. Debate regarding the best neuraxial technique for labor analgesia continues. Materials and Methods: The parturients of ASA grade I and II of age group 20–35 years were randomly divided into three groups of 20 each. Group E (epidural group) received 15 ml of 0.125% isobaric levobupivacaine with 30 μg fentanyl in the epidural space. Group CSE (combined spinal epidural group) received 2.5 mg of intrathecal isobaric levobupivacaine with 25 μg fentanyl and epidural top up of 15 ml of 0.125% levobupivacaine with 30 μg fentanyl. Group DPE (dural puncture epidural group) received 15 ml of 0.125% isobaric levobupivacaine with 30 μg fentanyl in epidural space; intrathecal medication was withheld. Epidural top-up doses were given as per Visual Analog Scale (VAS). Analgesic efficacy, extent of sensory and motor block, maternal and fetal outcome, duration of analgesia, and maternal satisfaction score were compared among three groups and analyzed statistically. Results: The onset and symmetry of sensory blockade and VAS score were better in CSE group. DPE group had better sacral coverage and less asymmetric blockade. Groups CSE and DPE had superior maternal and surgeon satisfaction scores in comparison to group E. Both groups E and DPE provided analgesia with minimal motor blockade and ambulation.
