SURGERY--COMPLICATIONS

This study looks at 150 women having heart bypass surgery to see which second-best graft works better: a leg vein taken with a special 'no-touch' method or an arm artery. The goal is to find out which graft stays open longer and causes fewer complications. Results will help docto…

This study tests if giving intravenous (IV) iron before spinal fusion surgery can reduce the need for blood transfusions in teens with scoliosis who are also iron deficient. About 120 participants aged 10-19 will receive either IV iron or a placebo before their scheduled surgery.…

This study compares light versus deep general anesthesia in older adults (65+ or Indigenous 55+) having major surgery. The goal is to see if lighter anesthesia reduces delirium, cognitive decline, and disability. About 2,766 participants will be randomly assigned to one of two an…

This study tests whether taking CoQ10 and glutathione before and after heart surgery can prevent acute kidney injury. About 242 adults having elective bypass surgery will receive either the supplements or a placebo. The goal is to see if this simple approach can protect kidney fu…

This study tests if doing a home-based exercise program before surgery can reduce disability 90 days after the operation. About 902 adults scheduled for major surgery will be split into two groups: one that follows the online exercise program and one that receives usual care. The…

This study tests whether fluvoxamine, a drug typically used for depression, can reduce the risk of delirium (sudden confusion) in older adults after non-cardiac surgery. Researchers will enroll 46 people to see if the approach is feasible and safe. If successful, it could lead to…

This study follows 15,000 adults aged 45 or older who are having same-day noncardiac surgery. The goal is to find out how often heart problems or other serious events happen after these procedures and what factors increase the risk. By tracking unplanned hospital visits and admis…

This study looks at whether how active you are before surgery can help predict your risk of complications or death after the operation. Researchers will track 50,000 adults having planned non-cardiac surgery at two hospitals. The goal is to see if adding physical activity to stan…

This study is testing whether wearable devices like Fitbits and Apple Watches can help doctors catch complications early after heart or lung surgery. Researchers will use machine learning to analyze data from 1,200 patients to predict recovery quality and detect problems sooner. …

This study follows 150 adults for one year after ankle arthroscopy to track any complications. Participants will be checked by surgeons and physical therapists at 15 days, 3 months, 6 months, and 1 year. They will also fill out questionnaires and do physical tests. The goal is to…
