Brief summary
Recently, the dural puncture epidural (DPE) technique has emerged as a novel method of labor analgesia. The DPE technique is a modification of the combined spinal epidural (CSE) technique, where a dural perforation is created from a spinal needle but intrathecal medication administration is withheld. The DPE technique has been shown to improve caudal spread of analgesia compared with epidural technique without the side effects observed with the CSE technique.
Detailed description
Investigators designed this prospective interventional study to determine if morbid obesity would influence DPE technique regarding labor analgesia onset and block characteristics.
Interventions
Parturients, between 18 and 45 years of age, with cervical dilation less than 5 cm were consented to receive a DPE technique, with a single dural puncture with a 26-gauge spinal needle. After successful placement of the epidural catheter and puncturing the dura; 20 mL of bupivacaine 0.25% was administered through the epidural catheter and a patient-controlled epidural infusion of bupivacaine was initiated.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Incidence of adequate analgesia | 5 minutes | The primary outcome of this study is the incidence of patients having adequate analgesia (VNRS \<30) at 5 minutes of epidural activation |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Verbal numerical pain score scale ( 0 being no pain and 100 being the worst pain ) | 6 hours | Verbal numerical pain score (VNRS) (pain) was recorded before epidural (0 min baseline), at 5 min, 10 min, 15 min and then every 15 min till 1 hour and then every 30 min till delivery. |
| Sensory level of DPE by pricking by blunt head of a pin | 6 hours | * Was recorded before epidural (0 min-baseline), at 5 min, 10 min, 15 min and then every 15 min till 1 hour and then every 30 min till delivery. * Sensory level of DPE was assessed by loss of sensation to prick by blunt head of a pin. |
| Motor block Bromage score (1 being complete motor block and 6 being no motor block) | 6 hours | * Motor strength was assessed with a modified Bromage score * Was recorded before epidural (0 min baseline), at 5 min, 10 min, 15 min and then every 15 min till 1 hour and then every 30 min till delivery. |
