Quadratus lumborum block (transmuscular approach) versus transversus abdominis plane block (unilateral subcostal approach) for perioperative analgesia in patients undergoing open nephrectomy: a randomized, double-blinded, controlled trial.

ABSTRACT:

Study objective

Patients undergoing open nephrectomy surgery experience severe perioperative pain, which is primarily due to incision of several muscles. Abdominal wall blocks are known to reduce pain without causing epidural-associated hypotension. We conducted this study to compare unilateral ultrasound-guided transmuscular quadratus lumborum block and posterior transversus abdominis block in combination with general anesthesia alone in terms of intraoperative and postoperative analgesics and hemodynamics and postoperative complications.

Methods

This was a randomized, double-blinded, controlled trial conducted in the operating room. This study included 48 patients aged 20-60 years, with ASA I and II, and a body mass index ≤ 30kg.m^-2 who were scheduled for open n
