First seen Jun 27, 2026 · Last updated Aug 06, 2026 · Updated 2 times

Summary

This study tests whether a new painkiller called oliceridine fumarate can control pain after lumbar spine surgery while helping the gut recover faster. Standard opioids often cause constipation and slow digestion. The trial will compare oliceridine to the usual drug sufentanil in 428 adults undergoing back surgery. Researchers will measure how quickly patients can eat solid food and pass gas or have a bowel movement within 24 to 48 hours after surgery.
