Lower thoracic paravertebral block via posterior pathway of medial arcuate ligament under direct visualization versus transmuscular quadratus lumborum block for postoperative analgesia following retroperitoneal laparoscopic nephrectomy: a randomized controlled trial.

ABSTRACT:

Background

The analgesic efficacy of transmuscular quadratus lumborum block (TQLB) as a means of decreasing the need for opioid use following laparoscopic nephrectomy has been demonstrated in several studies, but the effect of the lower thoracic paravertebral block via posterior pathway of medial arcuate ligament under direct visualization (LTPB-MAL) in this surgical context remains to be clearly elucidated.

Objectives

To juxtapose the pain-relieving potency of the TQLB and the LTPB-MAL in individuals receiving laparoscopic nephrectomy.

Design

A randomized controlled study.

Setting

University-affiliated tertiary care hospital.

Methods

One hundred and two individuals slated for laparoscopic nephrectomy under general anesthesia were assigned to acquire eit
