New study aims to ease back pain from spinal anesthesia
NCT ID NCT07198412
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether giving sedation before ultrasound-guided spinal anesthesia can lower the chance of back pain after surgery. Spinal anesthesia is common for lower body surgeries, but some people develop discomfort or long-lasting back pain. The researchers will compare standard methods with ultrasound guidance and sedation in 180 adults to find a safer, more comfortable approach.
