Ultrasound-guided bilateral pudendal nerve blocks of nulliparous women with epidural labour analgesia in the second stage of labour: a randomised, double-blind, controlled trial.

ABSTRACT:

Objective

To explore whether an ultrasound-guided pudendal nerve block (PNB) could decrease anaesthetic use, thereby shortening the length of the second stage of labour in women undergoing epidural analgesia.

Design

Prospective, single-centre, randomised, double-blind, controlled trial.

Setting

An obstetric centre in a general hospital in China.

Participants

72 nulliparous women were randomised, and 71 women completed the study.

Intervention

An ultrasound-guided bilateral PNB was administered to all study participants; the PNB group were given 0.25% ropivacaine 10 mL, while the control group were given 10 mL saline.

Main outcome measure

The primary outcome measure was the duration of the second stage of labour. Secondary outcomes included addition
