Is this trial a fit for you?

Likely a good fit

Ideal candidates are adults scheduled for major noncardiac surgery requiring substantial opioid analgesia.

Probably not a fit

Patients with contraindications to oliceridine or those who have chronic opioid use may not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This study evaluates the side effects of oliceridine, a medication approved for treating acute pain, in patients undergoing major noncardiac surgery. The research aims to determine if oliceridine causes fewer side effects compared to standard opioids. Patients will be monitored for respiratory compromise using a device that continuously tracks their breathing, with data kept blinded from clinical staff. The primary goal is to assess the proportion of patients experiencing significant respiratory issues within 24 hours after the first dose.

Why it matters

Potential benefit: If successful, this study could lead to safer pain management options for patients undergoing major surgery.

How similar studies have gone: Limited information suggests that oliceridine may be more effective with fewer side effects than traditional opioids, indicating potential success in similar studies.
