Erector spinae plane block spread patterns and its analgesic effects after computed tomography-guided hepatic tumour ablation: a randomized double-blind trial.

ABSTRACT:

Introduction

Spread patterns of the erector spinae plane block (ESPB) in a larger cohort of living subjects remain inadequately understood. This study investigated the spread of local anaesthetics or saline with contrast in patients undergoing computed tomography-guided radiofrequency ablation of hepatic tumours.

Patients and methods

Thirty patients participated in a double-blinded randomized controlled trial, 14 April 2021 and 18 January 2023. These patients were randomized into two groups: the ESPB group, which received local anaesthetic with contrast, and the sham group, which received saline with contrast. The spread of the drug was assessed regarding vertebral levels and its correlation with the patient characteristics. Pain intensity and morphine consumption were also
