Ultrasound guided quadratus lumborum block for postoperative analgesia after caesarean section under spinal anesthesia

Abstract

Background and Aims: Postoperative analgesia after caesarean section is important because 
it enables early ambulation. Several case reports have shown that local anaesthetic injection 
around the quadratus lumborum muscle is effective in providing pain relief after various 
abdominal operations and in patients with chronic pain. The aim of our trial was to access the 
analgesic efficacy of transmuscular quadratus lumborum block (TQLB) after caesarean 
section.
