Erector Spinae Plane Block Versus Paravertebral Block

• Status: Unknown status
• Trial end date: 2020-12-01
• Target enrollment: 0
• Participant gender: All

Summary

This study aims to compare the effectiveness of paravertebral block and erector spinae plane block after mastectomy.

The primary objective of this randomized controlled trial is to demonstrate equivalent dermatomal spread for ultrasound-guided single-injection Erector Spinae Plane (ESP) block performed at T4-T5 level and ultrasound-guided single-injection (paravertebral) PVB block at the same level.

Secondary objectives are Numerical Rating Scale (NRS) pain scores in the first 24 post-operative hours, opioid analgesia use intra-operatively and in the first 24 post-operative hours, block procedural time and patient discomfort during block insertion.

The investigators hypothesize that ESP block efficacy is not inferior to PVB with reference to dermatomal sensory spread and analgesic efficacy, while being easier to perform with less associated discomfort during block insertion.
