Sitting or lying down? study tests best position for pain block before chest surgery
NCT ID NCT07387484
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at whether the position you are in when you get a nerve block for chest surgery changes how well it works. Researchers will compare sitting up versus lying on your side in 90 adults having video-assisted chest surgery. The goal is to see which position gives better pain relief and uses less pain medicine.
