Effect of Sedation After Ultrasound-Guided Spinal Anesthesia on Back Pain

This study will evaluate whether giving sedation before spinal anesthesia, when performed with ultrasound guidance, reduces the risk of developing back pain after surgery. Spinal anesthesia is commonly used but may cause discomfort or persistent back pain in some patients. By comparing standard techniques, ultrasound guidance, and sedation, we aim to find safer and more comfortable approaches for patients undergoing non-obstetric surgery.
