Abstract

Background: This study investigated the optimal timing of analgesic transversus abdominis plane (TAP) block in the operating room for better recovery quality using the Korean version of the Quality of Recovery-40 (QoR-40K) questionnaire in patients who had undergone open inguinal herniorrhaphy. Methods: This single-centre, prospective randomised controlled study included adult male patients who had an ASA physical status of I–II. A total of 80 patients were analysed. The patients were randomly assigned and classified into pre-incisional TAP (pre-TAP) block (n = 40) and post-incisional TAP (post-TAP) block (n = 40) groups. The quality of postoperative functional recovery and complications were compared between the two groups during 24 h postoperatively. Results: Preoperative findings of the two groups were comparable. The global QoR-40K score was higher in the pre-TAP group than in the post-TAP group. Among sub-dimensions, scores of physical comfort and pain were higher in the pre-TAP group than in the post-TAP group. In the post-anaesthesia care unit, the pre-TAP group showed lower pain scores than the post-TAP block group. There was no severe pain in the pre-TAP group, but two patients (5.0%) in the post-TAP block group suffered severe pain. The pre-TAP group required lower doses of IV rescue opioid in the PACU than the post-TAP group. All patients were discharged from hospital on postoperative day 1 without surgical complications. Conclusions: The timing of analgesic TAP block may be of clinical importance to prevent postoperative pain and to improve the quality of early patient recovery following open inguinal herniorrhaphy.
