Brief Summary

DPEA (Dural Puncture Epidural Analgesia) is an alternative to the conventional epidural analgesia and technically a Combined Spinal Epidural (CSE) with omission of intrathecal drugs administration. To date, literature has proved several advantages of the DPEA techniquecompared to conventional epidural. However, these advantages are supposed to be limited to the use of 25 Gauge spinal needles. The aim of this project is to compare the quality of analgesia achieved after a DPEA technique performed with a 25 Gauge spinal needle versus a 27 Gauge spinal needle versus a conventional epidural, with a PIEB pump installed for analgesia maintenance. The Primary outcome will be the quality of analgesia, defined as the area under the curve (AUC) of the Numeric Pain Rating Scale (NPRS 100-0) ≤ 30 measured throughout labor and divided by labor duration (TWA-NPRS). 240 nulliparous women between the 36th and 42nd gestational week in active labor and with a cervical dilation ≤ 5 cm will be randomized according to a computer-generated random number sequence to receive a DPEA with a 25 Gauge spinal needle, a DPEA with a 27 Gauge spinal needle, or a conventional epidural.

Outcome Measures

Primary Outcomes (1)

Study Arms (3)

DPEA 27G

EXPERIMENTAL

Patients in the DPEA 27G group will receive an intentional dural puncture with a 27 Gauge Whitacre spinal needle, using the needle-through-needle technique (the epidural space will be identified using a 18 Gauge Tuohy needle).

Device: Dural Puncture Epidural Analgesia 27G

DPEA 25G

EXPERIMENTAL

Patients in the DPEA 25G group will receive an intentional dural puncture with a 25 Gauge Whitacre spinal needle, using the needle-through-needle technique (the epidural space will be identified using a 18 Gauge Tuohy needle).

Device: Dural Puncture Epidural Analgesia 25G
