Comparison of Thoracolumbar Interfascial Plane Block (TLIP-block) and Local Anesthetic (LA) Infiltration in Minimally Invasive Spine Surgery: A Randomized Controlled Trial

The goal of this clinical trial is to compare the effectiveness of the thoracolumbar interfascial plane block (TLIP block) versus local anesthetic (LA) infiltration in managing postoperative pain in minimally invasive surgery (MIS) for spine surgery. The primary outcome was total morphine consumption. Secondary outcomes included pain scores using the the numerical verbal scale (NRS), opioid-related side effects, time of the first request for rescue analgesia, time to ambulation and hospital length of stay.
