This study looks at how common low body temperature (hypothermia) is after surgery in recovery rooms. It aims to help improve patient care by measuring temperature changes and related outcomes.
Madrid, MadridAges 18 years+ - NCT07744009Recruiting
Awake breathing support for heart valve surgery
This trial tests a new anesthesia method that lets you breathe on your own during heart valve surgery, instead of using a breathing tube. It aims to see if this approach is safer and helps you recover faster than standard anesthesia.
Guangzhou, GuangdongAges 18 years+ - NCT07746505Recruiting
Remimazolam vs midazolam for anesthesia in older adults
This study compares two sedative medicines used to start general anesthesia in patients 65 and older having non-cardiac surgery. The goal is to see which one is safer and works better for older patients.
HangzhouAges 65 years+ - NCT07713121Recruiting
Keeping blood pressure up during surgery to prevent confusion in older adults
This trial tests whether keeping blood pressure at 85 mmHg or higher during surgery can reduce confusion (delirium) after surgery. It is for older adults with high blood pressure who are having non-cardiac surgery.
HamburgAges 65 years+ - NCT07700459Recruiting
Exercise prehabilitation for congenital heart surgery
This study tests whether a supervised exercise program before heart surgery can help adults with congenital heart disease recover better. You would join an exercise class 2–3 times a week for several weeks leading up to your operation.
LiverpoolAges 18 years+ - NCT06178510Recruiting
Breathing support after heart surgery
This trial tests a new way to help patients breathe after heart surgery. It compares standard breathing support with a new device that might help you recover faster in the ICU.
Vienna, State of ViennaAges 18–120 - NCT07661940RecruitingPhase 2
SP16 for kidney protection during heart surgery
This trial tests a drug called SP16 to see if it can prevent acute kidney injury in people with chronic kidney disease who are having elective heart surgery with a heart-lung machine. It aims to help preserve kidney function after surgery.
Erlangen, BavariaAges 18 years+ - NCT07642765Recruiting
Frailty Score and Blood Pressure Changes During Surgery
This study looks at a simple scoring system (EASIX) that predicts whether older or frail patients will experience dangerous blood pressure drops when anesthesia is given before surgery. Understanding this risk might help doctors better protect vulnerable patients during their operations.
KonyaAges 18 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+ - NCT07625553RecruitingPhase 2
Relaxin Agonist to Protect Kidneys During Heart Surgery
This study tests whether a drug called R2R01 can help protect your kidneys during major heart surgery. Heart surgery can sometimes damage the kidneys, and this trial is looking to see if this new medication reduces that risk.
MilanAges 18 years+ - NCT07604402Recruiting
Aortic Valve Replacement Without On-Site Surgery
This study tests a catheter-based procedure to replace a narrowed aortic valve without traditional open-heart surgery. It's designed for patients who are at higher risk for surgery due to age, health conditions, or anatomy.
AndriaAges Any age - NCT07611045Recruiting
Understanding recovery and care after heart surgery
This study asks patients and their families about their experience after heart surgery (like bypass or valve repair) to help doctors improve follow-up care. You'll share your story through an interview, and your feedback could help future patients.
Bristol, BristolAges 18 years+ - NCT07611890RecruitingPhase 4
Comparing two medications to reduce heart stress during cardiac surgery
This trial tests whether dexmedetomidine or lignocaine better prevents dangerous heart-rate and blood-pressure changes when a breathing tube is placed during heart surgery. If you're having cardiac surgery and are at high risk for heart complications, this study may help protect your heart during the procedure.
Rawalpindi, Punjab ProvinceAges 18–65 - NCT05849597RecruitingPhase 3
Dexmedetomidine to prevent delirium after open-heart surgery
This trial tests whether a sedating medicine called dexmedetomidine can reduce the risk of “delirium” (sudden confusion) in the intensive care unit after open-heart surgery. If you’re having certain heart operations, it may help protect your thinking and alertness during recovery.
KamenitzAges 18 years+ - NCT06399536Recruiting
Individualized blood management for major non-cardiac surgery
This trial tests a personalized approach to managing your own blood during surgery, which may reduce the need for donor blood transfusions. It is for people having planned non-cardiac surgery expected to need a large amount of blood.
Chengdu, SichuanAges 18–75 - NCT07593794Recruiting
Quality of Recovery After Heart Surgery Study
This study measures how well patients recover after planned heart surgery by having them answer questions about their physical and emotional wellbeing. The goal is to understand what affects recovery so doctors can better support patients afterward.
KocaeliAges 18 years+ - NCT07588230Recruiting
