Recruiting studies
- 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.

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
Stomach stimulation to help bowel recovery after major surgery
This trial tests a stomach (gastrointestinal) stimulation approach to help your bowels start working again after extensive surgery, which may cause a temporary problem called postoperative ileus. If it helps, it could mean faster recovery and less time with bowel-related complications.
AarhusAges 18 years+ - NCT05777824RecruitingPhase 2
Testing treatment after head and neck cancer response to chemo-immunotherapy
This Phase 2 study looks at what treatment is best after you first receive chemotherapy plus immunotherapy, then have surgery for head and neck squamous cell cancer. It tries to use how your tumor responds (shown in lab tissue after treatment) to guide the next steps, which may improve outcomes.

Pregabalin during weight-loss surgery to reduce pain
This trial tests whether pregabalin can help with pain control for people having laparoscopic sleeve gastrectomy (a weight-loss surgery). It may help reduce the discomfort around surgery and improve the overall recovery experience.
Warsaw, WarsawAges 18 years+ - NCT05847010Recruiting
Study program to prevent postoperative delirium in older adults
This study adds an extra scientific program to help prevent confusion (“delirium”) after surgery in older adults. If you were already planned to join the main prevention program, this may help improve how care is delivered and how outcomes are measured.
BerlinAges 70 years+ - NCT05898035Recruiting
Testing symptoms after root-end dental surgery
This study looks at what symptoms you feel after endodontic microsurgery (a type of root-end tooth procedure). It will help doctors understand what to expect after surgery in properly selected patients.
IrbidAges 18–65 - NCT05906134RecruitingPhase 1/Phase 2
Pain control plan after minimally invasive esophagus surgery
This trial tests a pain-control method (using an epidural/nerve pain-block through the back, called neuraxial anesthesia) for people having minimally invasive esophagus removal surgery. It may help reduce pain after surgery and improve comfort during recovery.
Seattle, WashingtonAges 18 years+ - NCT05917262Recruiting
Mindfulness breathing vs heart-rate training after shoulder surgery pain
This trial compares two non-drug techniques—mindful breathing and heart-rate (HR) biofeedback—to see which helps reduce pain after shoulder surgery. You may be able to join if you have ongoing shoulder pain after surgery and haven’t been using these practices very often.
TaoyuanAges 18 years+ - NCT05990946Recruiting
Smartphone monitoring after lung cancer surgery
This trial tests if using a smartphone app to track your symptoms after minimally invasive lung cancer surgery can help you stick to your recovery exercises. It aims to improve your recovery by keeping you connected with your care team.
Zhongshan, GuangdongAges 18–75 - NCT06005363Recruiting
Brain fluid study in shunt surgery patients
This study looks at brain fluid and drainage function in patients receiving a VP shunt for hydrocephalus. It may help understand how the brain clears waste products.
TaoyuanAges 60 years+ - NCT06023225Recruiting
Sex hormones, pain, and opioid use in girls after surgery
This study looks at how sex hormones affect pain and the use of pain medicine after orthopedic surgery in girls. It might help explain why some people need more pain relief than others.
St Louis, MissouriAges 11–16 - NCT06052397Recruiting
Sleep and body clock markers for confusion after surgery
This trial tests whether sleep patterns and body clock signals can help predict confusion after major orthopedic surgery. You would wear a watch that tracks movement to see how your sleep relates to recovery.
Boston, MassachusettsAges 70 years+ - NCT06053476Recruiting
Chest tube and pain care after lung surgery for collapsed lung
This study compares two ways to manage the chest tube and pain after surgery for a collapsed lung (pneumothorax). The goal is to find out which approach helps patients recover faster and with less pain.
VeldhovenAges 16 years+ - NCT06054360Recruiting
Predicting irregular heartbeat after heart bypass surgery
This study uses an ultrasound test of the heart's right atrium to see if it can predict who will develop an irregular heartbeat (atrial fibrillation) after planned coronary bypass surgery. If you are scheduled for this surgery and have no history of atrial fibrillation, you may be able to join.
AmiensAges 18 years+ - NCT06083558Recruiting

This study looks at pain and nausea in adults who had their first gallbladder surgery between 2016 and 2025. It uses a national registry to understand recovery and help improve care.
Sundsvall, XAges 18 years+ - NCT06088602Recruiting
Cold therapy for pain after knee replacement
This trial tests a cold treatment called cryoneurolysis to reduce pain after knee replacement surgery. It may help you move better and use less pain medication.
HvidovreAges 18 years+ - NCT07607262Recruiting
Comparing two injection methods for pain relief after gallbladder surgery
This trial tests two ways of giving pain medicine during gallbladder removal surgery. One method uses standard local anesthetic injection, the other uses a special injection technique that may provide better pain relief.
Sancaktepe, IstanbulAges 18–75 - NCT06145516Recruiting
Sleep program to ease pain after joint replacement

Calming medicine during brain tumor surgery
This trial tests if a calming medicine (dexmedetomidine) given during and after brain tumor surgery can help prevent confusion or delirium afterwards.
BeijingAges 18 years+ - NCT06170710RecruitingPhase 2
Immunotherapy after chemoradiation for high-risk head and neck cancer
This trial tests if adding immunotherapy after standard chemoradiation helps prevent cancer from returning in people with high-risk head and neck cancer. It is for those who have completed surgery and have certain high-risk features.
Beijing, Beijing MunicipalityAges 18–70 - NCT06176144Recruiting
Comparing two anesthetics for confusion after surgery in older adults

Common questions
- Are there clinical trials for postoperative?
- Yes. Clin2 currently lists 1,419 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.
