Repeated Pudendal Nerve Block and Physiotherapy for Prevention of Chronic Post-Episiotomy Pain
Sponsor: Vinmec Healthcare System
Summary
This prospective, single-center, open-label, randomized controlled trial will evaluate whether repeated ultrasound-guided pudendal nerve block combined with standardized physiotherapy and standard postpartum analgesic management reduces persistent post-episiotomy pain and postpartum dyspareunia compared with standard management alone. Women aged 18-40 years who have undergone vaginal delivery with episiotomy or a first-time perineal tear and who report postpartum pain greater than 3/10 within 24 hours after delivery will be randomized in a 1:1 ratio. The intervention group will receive standard management plus a repeated pudendal nerve block before hospital discharge and a second block on postpartum Day 10 if pain remains greater than 3/10. Pain and sexual function will be assessed through 3 months postpartum.

Interventions
Ultrasound-Guided Pudendal Nerve Block
A transperineal ultrasound-guided pudendal nerve block will be performed using a high-frequency linear ultrasound probe on the side of the episiotomy. The pudendal neurovascular bundle will be identified and the needle advanced under ultrasound guidance. After negative aspiration, a mixture of 0.5% ropivacaine 8 mL and dexamethasone 4 mg will be injected incrementally. Participants will be monitored for at least 30 minutes following the procedure
