Open inguinal hernia repair can be associated with considerable postoperative discomfort and potentially lead to the development of chronic, debilitating pain. Transversus abdominis plane (TAP) blocks have shown some success in reducing pain following abdominal surgery. This study evaluated the analgesic efficacy of a continuous TAP block in reducing opioid consumption postoperatively compared to sham procedure. Secondary outcomes included pain scores, opiate related side effects, and activity assessment scores.
Randomized, double-blind, placebo controlled study.
72 patients undergoing open inguinal hernia repair recruited.
Catheters placed preoperatively under ultrasound guidance.
