Recruiting studies
- NCT05331118Recruiting
Study of complications and long-term outcomes after major surgery

Colchicine for heart risk during major non-heart surgery
This study tests whether a low-cost, anti-inflammatory drug called colchicine can reduce heart complications after major non-heart surgery. If you have heart or blood vessel risk factors and are scheduled for a major operation, this trial may help protect your heart.
Sankt Gallen, Canton of St. GallenAges 45 years+ - NCT05738603Recruiting
Predicting low blood pressure during head and neck flap surgery
This study looks at a way to predict low blood pressure during head and neck free flap surgery (when tissue is moved from one place to another). If successful, it may help the surgical team prevent complications by preparing earlier.
Poznan, PoznańAges 18 years+ - NCT04256798RecruitingPhase 3
Respiratory care after high-risk abdominal surgery
This trial looks at a breathing-focused care plan given around the time of major abdominal surgery to improve recovery and outcomes. You may be eligible if you’re having a large midline abdominal incision and can be followed after surgery.
Botucatu, São PauloAges 10–100 - NCT07646730Recruiting
Wearable Watch to Detect Complications After Lung Surgery
This study tests whether a wearable device (a smartwatch-like device) worn after lung or chest surgery can help doctors catch complications early by monitoring your heart rate, activity, and other vital signs. The goal is to catch problems sooner so you can get help faster.
Wuhan, HubeiAges 18 years+ - NCT06445881RecruitingPhase 2
Herbal medicine for lung cancer before and after surgery
This trial is testing whether adding a traditional Chinese herbal formula (Modified Si Jun Zi Tang) to standard treatment before and after surgery can help people with early-stage non-small cell lung cancer. It aims to see if the herbs improve outcomes and reduce side effects.
Hangzhou, ZhejiangAges 18–75 - NCT06566053Enrolling by invitation
Predicting risks in thoracic surgery
This study is creating a tool to better predict risks and guide care during and after thoracic surgery. If you are having an operation in the thoracic surgery department, this research may help improve your safety and recovery.
Changsha, HunanAges 18 years+ - NCT06732193Recruiting
Fissios App for recovery after lung cancer surgery
This trial tests whether using a smartphone app (Fissios) after lung cancer surgery helps you recover with fewer complications. If you are scheduled for lung surgery for non-small cell lung cancer and have a smartphone, you may be eligible.
Madrid, MadridAges 18 years+ - NCT03954678Recruiting
Exercise program during hospital care for urologic surgery
This study looks at whether doing an exercise routine around the time of urologic (urinary tract) surgery is safe and helpful for recovery. It asks you to do daily steps, answer questionnaires, and allow routine bloodwork.
Atlanta, GeorgiaAges 18 years+ - NCT04266574Recruiting
Blood pressure–guided care for older or frail surgical patients
This study tests a goal-based blood pressure treatment approach during major surgery for people at higher risk (often older or frail with high blood pressure). The goal is to see if this BRAIN-targeted strategy can improve how patients do after surgery.
Rozzano, MilanAges 18 years+ - NCT04876950Recruiting
Remote check-ins after surgery using a tablet
This trial tests a virtual follow-up program after surgery, using remote automated monitoring and tablet-based check-ins. It may help with safer recovery by letting the care team follow how you’re doing after you leave the hospital.
Hamilton, OntarioAges 40 years+ - NCT06655506Recruiting
Enhanced Recovery for Gynecologic Cancer Surgery
This trial studies whether an enhanced recovery after surgery (ERAS) program improves outcomes for people with gynecologic cancer. It aims to help you recover faster and with fewer complications.
Athens, AthensAges 25–85 - NCT06962007Recruiting
Jaw clenching after sugammadex for muscle relaxation reversal
This trial tests whether a drug called sugammadex, which reverses muscle relaxation from anesthesia, might cause jaw clenching in some people. The study will watch for this effect during routine surgery to better understand the risk.
Iksan, Jeonbuk-doAges 19–70 - NCT07165236Recruiting
Bladder tumor surgery and memory changes study
This study looks at how bladder tumor surgery might affect thinking and memory. It checks blood markers to see if they are linked to any mental changes after the operation.
Osijek, CroatiaAges 18–80 - NCT06077422Enrolling by invitationPhase 2/Phase 3
Comparing two pain blocks for heart surgery recovery
This trial compares two types of pain blocks (Exparel vs. Marcaine) given during heart surgery to see which one provides better pain relief. If you are scheduled for a heart surgery through a small or full chest incision, you may be able to join.
New Brunswick, New JerseyAges 18 years+ - NCT07519733Recruiting
Exercise Testing Before High-Risk Surgery
This study tests whether a simple exercise test before surgery can help doctors better predict and prevent complications in older adults undergoing major operations. You'll do a gentle exercise test on a stationary bike or treadmill to measure your fitness level.
New Haven, ConnecticutAges 45 years+ - NCT05199025Recruiting
Study of blood and lab markers around major surgeries
This study checks blood and other lab “biomarkers” during the time before and after major surgeries to see if they can help guide perioperative care. You might be eligible if you are having certain planned heart, lung, GI, or blood-vessel surgeries and can give informed consent.
Breda, North BrabantAges 18 years+ - NCT05755230Recruiting
Study of health results around surgery

- Yes. Clin2 currently lists 50 recruiting perioperative complication 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 perioperative complication 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 perioperative complication 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.
