Lumbar Surgery

This randomized controlled trial evaluates the effectiveness of ultrasound-guided retrolaminar nerve block in addition to standard multimodal analgesia for postoperative pain management in patients undergoing lumbar spine surgery. Fifty patients will be randomly assigned to receive either the retrolaminar block combined with standard pain management or standard pain management alone. The primary outcome is total opioid consumption in the first 24 hours after surgery. Secondary outcomes include pain intensity at multiple time points, time to first rescue analgesia, duration of sensory block, incidence of postoperative nausea and vomiting, length of hospital stay, patient satisfaction, and chronic pain development at 3 and 6 months follow-up.

In this study, the researcher will examine the effects of preoperative mobilization training (video viewing with VR glasses and brochure methods) given to patients undergoing surgery in the lumbar region on pain, anxiety, fear of movement, fear of falling, and mobility levels in the postoperative period, using specific scales.

The aim of this study is to evaluate the incidence of myocardial injury after noncardiac surgery (MINS) in patients undergoing lumbar surgery, and to investigate the associated risk factors.
