Study on Ultrasound-Guided Spinal Anesthesia With or Without Sedation to Reduce Back Pain After Non-Obstetric Surgery in Adults

What this Trial Is About

Researchers are evaluating whether sedation given before spinal anesthesia, guided by ultrasound, can reduce the risk of developing back pain after surgery. The trial focuses on adults undergoing non-obstetric lower abdominal or lower limb surgery, comparing standard landmark-guided spinal anesthesia to ultrasound-guided techniques with and without sedation. The goal is to find safer and more comfortable anesthesia methods to lower acute and chronic back pain following surgery. The study includes three groups one receives ultrasound-guided spinal anesthesia without sedation another receives ultrasound-guided spinal anesthesia with pre-procedure sedation using midazolam and the third group receives traditional landmark-guided spinal anesthesia without ultrasound or sedation. All patients receive standardized anesthesia with intrathecal bupivacaine after local lidocaine infiltration. Sedation, when used, is given intravenously shortly before the spinal procedure. Oxygen and standard monitoring are provided during the procedure. Participants will be assessed for back pain incidence and severity shortly after surgery and at 1, 3, and 6 months later using pain scales and questionnaires. Other measures include the number of needle insertion attempts, procedure time, patient satisfaction, and complications such as headache or nausea. The study lasts through these follow-ups to track both immediate and long-term effects of the different anesthesia approaches.
