Effect of Sedation After Ultrasound-Guided Spinal Anesthesia on Back Pain
Sponsor: Benha University
Summary
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.
Official title: Impact of Ultrasound-Guided Spinal Anesthesia and Pre-Procedure Sedation on Postoperative Acute and Chronic Back Pain in Non-Obstetric Surgery.

Interventions
Ultrasound-guided spinal anesthesia
Spinal anesthesia performed under real-time ultrasound guidance using a curvilinear ultrasound probe and 25-27G pencil-point spinal needle. Intrathecal injection of bupivacaine 0.5% hyperbaric (12-15 mg) following local infiltration with lidocaine 1% (2-3 mL).
Midazolam plus ultrasound-guided spinal anesthesia
Patients will receive midazolam (0.02-0.05 mg/kg IV; max 5 mg) 5-10 minutes prior to spinal anesthesia. Ultrasound guidance used for spinal needle placement. Intrathecal bupivacaine 0.5% hyperbaric (12-15 mg) after lidocaine 1% (2-3 mL) infiltration. Oxygen supplementation at 2 L/min and standard monitoring.
Landmark-guided spinal anesthesia
Spinal anesthesia performed using the traditional landmark palpation technique without ultrasound guidance or sedation. Intrathecal bupivacaine 0.5% hyperbaric (12-15 mg) after lidocaine 1% (2-3 mL) infiltration, using a 25-27G pencil-point spinal needle.
