Predicting high blood pressure after surgery in older adults

This study uses ultrasound measurements of the carotid artery and vena cava to predict if older patients might experience low blood pressure after going under general anesthesia for elective surgery. If successful, it could help doctors take preventive steps.

This study tests special ways of analyzing blood-pressure recordings during major surgery to better understand why some people develop low blood pressure (hypotension). If you have high blood pressure and need invasive blood-pressure monitoring, your surgery team will use readings to study patterns that may help predict or prevent low blood pressure.

This study looks at how blood pressure medications affect low blood pressure episodes that happen during and after heart surgery. Researchers want to understand if the number of blood pressure drugs you take before surgery changes how your body handles blood pressure during the operation.

This study uses an ultrasound to measure blood flow in the neck's main artery to see if it can predict a dangerous drop in blood pressure after you are put to sleep for surgery. It is for adult patients with chronic liver disease who are having planned surgery.

This study is testing a new tool called the Hypotension Prediction Index to help predict and prevent dangerously low blood pressure during surgery. It may be especially helpful for older, frail patients having long abdominal surgeries.

This study tests a computer model that uses heart-rhythm measurements to predict whether your blood pressure will drop dangerously after anesthesia begins. If accurate, it could help doctors prepare and protect you during surgery.
