Gabapentin to help children use less opioid after surgery
This study tests whether gabapentin can reduce how much opioid pain medicine children need after certain major chest or heart surgeries. If it works, it may lower opioid-related side effects while still helping with postoperative pain.
Sacramento, CaliforniaAges Up to 17 years - NCT04725916Recruiting
Study of water exposure and drain-related risks after certain surgeries
This trial looks at how using water (like showers) affects risks related to surgical drains after specific cosmetic or reconstructive procedures. Your results may help improve post-surgery safety guidance for patients who go home with drains.
Danville, PennsylvaniaAges 18 years+ - NCT04912531Recruiting
Virtual reality and smell tools to ease surgery pain
This trial tests whether a combination of virtual reality and guided smells can reduce pain and anxiety around major heart and chest surgeries. If you’re scheduled for one of the listed operations, the study may help make recovery feel more comfortable by using sensory-based distraction.
Boston, MassachusettsAges 18 years+ - NCT07699601RecruitingPhase 2/Phase 3
Testing a pain tablet after orthopedic surgery
This trial tests an investigational tablet called HL-1186 for controlling pain after orthopedic surgery. It explores whether the drug can safely reduce moderate to severe pain when given after the procedure.
Changsha, HunanAges 18–75 - NCT07697222Recruiting
Pain block comparison for pectus excavatum repair
This trial compares two types of nerve blocks to control pain after a minimally invasive surgery to fix a sunken chest. It aims to see which block works better for recovery.
Istanbul, IstanbulAges 15–25 - NCT05009771Recruiting
Testing a pain-control method after C-section
This study looks at how to better manage pain after a C-section using spinal anesthesia and either a patient-controlled IV pain pump or a specific pain medicine (naldebaein). You may be able to join if you’re scheduled for a C-section at 37–40 weeks and can take the usual pain medicines.
New Taipei City, TaiwanAges 20–40 - NCT05010148RecruitingPhase 3
IV lidocaine after spinal fusion to reduce delirium and pain
This trial tests whether giving lidocaine through a vein after elective spinal fusion surgery can help prevent confusion (delirium) and reduce pain. It may help people recover more comfortably and think more clearly after surgery.
San Francisco, CaliforniaAges 60 years+ - NCT05124236Recruiting
Pre-surgery vs post-surgery focused radiation for brain metastases
This trial compares two ways of giving focused radiation for brain metastases: before surgery or after surgery. It aims to see which timing works better to control tumors while keeping you safe.
InnsbruckAges 18 years+ - NCT05140993Recruiting
Emotional and orientation support to prevent delirium after surgery
This study tests whether extra emotional help and re-orienting (helping you know where you are and what’s happening) can lower the risk of confusion called postoperative delirium after surgery. It is designed for older adults having certain types of non-heart, non-brain surgery.
Tel AvivAges 70–120 - NCT05146336Recruiting
CytoSorb registry for critically ill patients needing blood treatment
This registry collects information about critically ill patients who receive the CytoSorb 300 mL blood treatment. It may help doctors better understand when the treatment works best and when it should not be used.
KlagenfurtAges Any age - NCT05168280Recruiting
Dexmedetomidine during brain surgery to prevent confusion in seniors
This trial tests whether giving a medication called dexmedetomidine during selective brain surgery can help prevent postoperative delirium, a sudden episode of confusion, in older adults. If you qualify, the study team would give the medication during the operation and compare outcomes after surgery.
Beijing, Beijing MunicipalityAges 65 years+ - NCT05193227RecruitingPhase 2
Slow-release lidocaine patch for pain after pelvic surgery
This Phase 2 study tests a slow-release form of lidocaine to reduce pain after surgery that uses a pelvic incision. If you’re having a qualifying pelvic operation, the study may help see whether this medication improves postoperative pain control.
Vancouver, British ColumbiaAges 19 years+ - NCT05198635Recruiting
Cerebral oxygen checks to lower confusion after carotid surgery
This trial looks at whether monitoring oxygen levels in the brain during carotid endarterectomy (a surgery to reduce stroke risk) can help reduce postoperative delirium, a sudden period of confusion after surgery. It may help patients recover more clearly after the operation by identifying risks early and guiding care.
Beijing, Beijing MunicipalityAges Any age - NCT05272280Recruiting

Brain chemistry study after surgery in older adults
This study looks at how brain “metabolomics” (small chemical signals in the brain/body) relate to thinking or mood problems that can happen after surgery in people age 65 and older. It may help doctors understand who is more likely to have these side effects after an operation.
Shanghai, Shanghai MunicipalityAges 65 years+ - NCT05752071Recruiting

- Yes. Clin2 currently lists 1,411 recruiting postoperative studies from the U.S. registry, each rewritten for real people, not researchers, so you can see what it’s testing and who it’s for.
- How do I know if I qualify for a postoperative trial?
- Each study lists its eligibility criteria — rules about age, diagnosis, and prior treatments. On every Clin2 trial page we explain these in words written for real people and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Does it cost anything to join a postoperative trial?
- Using Clin2 is always free. Many trials cover the cost of the study treatment and related visits; some reimburse travel. The study team explains exactly what’s covered before you decide.
