Magnesium sulfate beats dexmedetomidine for Post-Surgery pain relief
NCT ID NCT07445451
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looked at 93 adults having bladder tumor surgery under spinal anesthesia. It compared two intravenous drugs—magnesium sulfate and dexmedetomidine—to see which better controlled pain after surgery. Magnesium sulfate led to lower pain scores, delayed the need for extra painkillers, and reduced total painkiller use, with no major safety issues.
