Heart rate variability and delirium after major abdominal surgery in older adults
Part of Brain & nervous system, Mental health clinical trials.
This study looks at whether heart rate variability (a measure of your heart's ability to adapt to stress) can help predict delirium (confusion or disorientation) after major abdominal surgery in older adults. You may qualify if you are 65-85 years old, having major abdominal surgery, and do not have serious heart, nervous system, or memory problems.
Summary written for real people, not researchers, by Clin2.
Who can take part
- Are 65 to 85 years old.
- Are scheduled for major abdominal surgery under general anesthesia.
- Expected to stay in the hospital for at least 7 days after surgery.
- Have a body mass index (BMI) between 18.5 and 28.0.
- Are classified as ASA I, II, or III (generally healthy to mild or moderate systemic disease).
- Are conscious, mentally competent, and able to cooperate with heart rate variability measurements and questionnaires.

This study looks at brain wave patterns during surgery in older adults to better understand and predict confusion after surgery. If you are 60 or older and having joint or spine surgery, you may be able to help.
This study tests a new way to predict delirium (sudden confusion) after heart surgery by using brain monitoring. It may help doctors detect early warning signs so they can act faster.
This study tests if a special heart monitor can predict confusion (delirium) after your surgery. It's for people having moderate to major leg or bone surgery, not on the spine.
This study looks at factors that may increase the risk of developing confusion or delirium after heart surgery. If you have had heart surgery before, researchers want to see if they can predict who might become confused afterward, which could help prevent it in the future.
This study measures how your heart rate varies after planned colorectal surgery to see if these changes can predict complications. Researchers will monitor your heart rhythm before and after your operation to understand whether certain patterns might warn of problems early.
This study is testing a new way to predict if a person will become confused or disoriented (delirium) after heart surgery. It looks at people having planned heart valve or bypass surgery while using a heart-lung machine, and who will stay in the ICU for more than two days.
