No results posted yet for this study

Summary

The goal of this clinical trial is to compare the effects of single-level and bi-level erector spinae plane block in open inguinal hernia repair surgery. The main question it aims to answer are:

* Whether bi-level ESP block will improve pain control after open inguinal hernia repair surgery
* Whether bi-level ESP block will improve quality of recovery after open inguinal hernia repair surgery

Participants will receive erector spinae plane block, and will be randomised into 2 groups, single-level ESP block and bi-level ESP block, before open hernia repair surgery. They will be followed up after operation for assessment of pain control and quality of recovery.

Conditions

  • Hernia, Inguinal

Interventions

PROCEDURE

Erector spinae plane block

ESP block is a paraspinal fascial plane block that involves injection of local anesthetic underneath the anterior fascia of the erector spinae muscles. Local anaesthetic mixture (lignocaine 2% with adrenaline, bupivacaine 0.25%) will be delivered with insulated needle in bolus(es) to above-mentioned levels (L1 in 1ESP group, T12 \& L1 in 2ESP group)
