Research Triangle Park, North CarolinaAges 18 years+ - NCT07217197Enrolling by invitation
A monitor to detect breathing problems after surgery
This trial tests a new respiratory monitoring system to see if it can detect and predict opioid-induced respiratory depression (OIRD) — when pain medicines slow your breathing too much — in patients recovering from surgery. The monitor uses a face mask, nasal cannula, and small sensors to track breathing continuously, so that doctors can step in early if there is a problem.
Philadelphia, PennsylvaniaAges 18 years+ - NCT06774274RecruitingPhase 4
Ketamine for pain after major orthopedic surgery: drip vs. pump
This study tests two ways of giving a medicine called ketamine to control pain after major bone or joint surgery. One method is a steady infusion (drip) through a vein, and the other is a patient-controlled pump (PCA) that lets you press a button for more medicine when you need it.
Medellín, AntioquiaAges 18 years+ - NCT07208305RecruitingPhase 3
Testing a drug combo for opioid-related nausea

Common questions
- Are there clinical trials studying Opioid?
- Yes. Clin2 currently lists 430 recruiting studies that include Opioid, drawn from the U.S. registry and rewritten for real people so you can see what each is testing and who it's for.
- How do I know if I qualify for a Opioid trial?
- Each study lists its own eligibility criteria — rules about condition, age, and prior treatments. On every Clin2 trial page we explain these in plain language and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Is Opioid an approved treatment?
- A drug being studied in a trial may be investigational (still being tested) or already approved and being studied for a new use. Each study page explains what phase it's in. Clin2 does not provide medical advice — talk with your doctor about whether Opioid or a specific trial is right for you.
