This study looks at how often older adults develop sudden confusion (delirium) after non-heart operations under general anesthesia. It may help doctors better predict who is at risk and improve care after surgery.
New Delhi, National Capital Territory of DelhiAges 65 years+ - NCT06096116RecruitingPhase 3
Trial of a blood product for heparin resistance during heart surgery
This study tests a blood-derived medicine (antithrombin) to help people who do not respond well to the blood thinner heparin during heart surgery. It aims to make surgery safer by improving blood thinning.
Stanford, CaliforniaAges 18–85 - NCT06788743Recruiting
Sevoflurane vs. propofol for preventing confusion after surgery in older diabetics
This trial compares two common anesthesia drugs (sevoflurane gas vs. propofol injection) to see which one lowers the risk of confusion or delirium after surgery in older adults with diabetes. It aims to find a safer way to give anesthesia for your operation.
Xi’an, ShanxiAges 60 years+ - NCT07632131Recruiting
Storytelling therapy to prevent PTSD after heart surgery
This study tests whether a special therapy called narrative exposure—where you talk through your surgery experience with a trained counselor—can help prevent PTSD (post-traumatic stress) in people recovering from heart surgery in the ICU. The goal is to help you process what happened so you feel less distressed afterward.
Fuzhou, FujianAges 18 years+ - NCT07012668Recruiting
Treatments for heart-brain conditions and post-surgery stroke
This trial is studying different treatments for people who have conditions that affect both the heart and brain, or who have had a stroke or other brain blood vessel problem after heart surgery. The goal is to find out which treatments work best and see what factors affect the results.
BeijingAges 18 years+ - NCT06066970Recruiting
Studying heart markers after valve surgery
This trial uses a special MRI and blood tests to see how heart muscle is affected after aortic or mitral valve surgery. It may help doctors better understand and monitor heart recovery.
Freiburg im Breisgau, Baden-WurttembergAges 18 years+ - NCT07232277Recruiting
Vein congestion and kidney injury after heart surgery
This trial looks at how fluid buildup in veins might relate to kidney injury after planned heart surgery. It aims to find ways to prevent kidney damage. Participants must be having planned (non-emergency) heart surgery, be 18 or older, and have healthy kidneys and overall health.
Yangzhou, JiangsuAges 18 years+ - NCT06336746Recruiting
Heart function during steep head-down position in robotic surgery
This study looks at how your heart performs during robotic surgery when you are placed in a steep head-down position. It may help doctors better understand how to keep you safe during the procedure.
Karlstad, Värmland CountyAges 18 years+ - NCT06802224RecruitingPhase 4
Medication to prevent kidney injury after major surgery
This study compares two medications given during surgery to see which one better protects the kidneys after the procedure. If you are having major non-cardiac surgery that lasts at least 2 hours and you need medication to support your blood pressure, this trial may be a good fit.
San Francisco, CaliforniaAges 18 years+ - NCT04973579Recruiting
Stent plus heart surgery for high risk carotid patients
This trial looks at whether doing carotid artery stenting at the same time as heart surgery is safe and effective for people at high risk of stroke around the time of surgery. It targets people with significant carotid narrowing who also need heart surgery for specific heart problems.
