Abstract

Objectives: Truncal blocks have a place within multimodal analgesia techniques in abdominal 
surgery. The quadratus lumborum block is an abdominal truncal block used for somatic analgesia of 
both the upper and lower abdomen. In this prospective, double blind, randomized study, we aimed to 
compare quadratus lumborum block and transversus abdominis plane block in pediatric patients 
undergoing laparoscopic lower abdominal surgery. Patient and methods: A total of 60 pediatric 
patients of both sex, ASA I and II, aged between 1 to 7 years, scheduled for laparoscopic lower 
abdominal surgery, under general anesthesia were included in the study. Patients were randomly 
allocated into 2 equal groups each containing 30 patient. Group (QLB) received bilateral ultrasound 
guided Quadratus Lumborum Block and group (TAPB) received bilateral ultrasound guided 
transversus abdominis plane block. Pain levels were assessed. Results: the patients who received 
quadratus lumborum block showed lower post-operative pain score and receive less rescue analgesia 
than TAP block group. Parent satisfaction scores were higher in the quadratus lumborum block group 
(P < 0.05). Conclusions: The results of this study showed that in pediatric patients undergoing 
elective laparoscopic lower abdominal surgeries the quadratus lumborum block provided longer and 
more effective postoperative analgesia compared with the transversus abdominis plane block.
