Analgesic efficacy of two approaches of ultrasound-guided quadratus lumborum block for laparoscopic renal surgery: A randomised controlled trial.

ABSTRACT:

Background

Moderate-to-severe pain exists in the early postoperative period after laparoscopic renal surgery.

Objective

We investigated the analgesic effect of quadratus lumborum block (QLB) via two approaches in patients undergoing laparoscopic renal nephrectomy.

Design

A randomised controlled trial.

Setting

An academic tertiary care hospital in Beijing, China.

Participants

Ninety-six patients aged 18 to 70 years who were scheduled for elective laparoscopic radical or partial nephrectomy.

Interventions

Eligible patients were allocated randomly to a control group (no block), lateral QLB group or posterior QLB group. Ultrasound-guided QLB was performed via either the lateral or posterior approach with 30 ml of 0.4% ropivacaine before surgery.
