About this trial
The aim of this prospective randomized clinical study is to compare the analgesic efficacy and side effects of modified thoracolumbar interfascial plane block and quadroiliac plane block applied preoperatively in patients undergoing lumbar microdiscectomy surgery.The study will include a total of 80 patients aged 18-65 years with ASA I-III, with 40 patients in each group( Group mTLIP and Group QIPB) undergoing lumbar microdiscectomy surgery.
The primary objective of the study is to compare groups in terms of PCA opioid consumption during the 48-hour postoperative period. Secondary objectives are to compare groups in terms of QoR-15 recovery score, dynamic and static numerical rating scale scores, total rescue analgesic use, time to first request for rescue analgesia, length of hospital stay, block and opioid-related side effects and complications, and perioperative remifentanil infusion dose.
