Ultrasound study to check blood flow before heart surgery
Part of Heart & circulation clinical trials.
This study uses a harmless ultrasound to take pictures of a large vein (inferior vena cava) in your belly before heart surgery. The goal is to see how well it shows changes in blood flow, which could help doctors monitor your heart and fluids during and after surgery.
Summary written for real people, not researchers, by Clin2.

- You are 18 years or older.
- You are scheduled for heart surgery at Sunnybrook Hospital.
- You are breathing on your own (not on a breathing machine).

This trial tests whether using ultrasound to measure a vein near your heart (the inferior vena cava) can help prevent low blood pressure (hypotension) when you go under anesthesia for surgery. It is for older adults (65-85) scheduled for non-cardiac surgery.
This study looks at blood flow patterns in patients after non-emergency heart surgery to see if they relate to recovery in the ICU. It uses a special ultrasound to check blood vessels in the belly and leg.
This trial uses ultrasound to measure blood flow and fluid levels in the body before brain surgery. It aims to help doctors manage fluids better during and after anesthesia.
This trial tests whether using a heart ultrasound before surgery can help doctors better manage your blood volume. If you are having surgery under general anesthesia and have a higher risk of heart problems, this study may help improve your safety.
This study tests if using ultrasound during heart bypass surgery can help doctors see how well blood flows through the new bypass tubes. This might improve the success of the surgery and recovery.
This study uses a simple ultrasound on the upper chest to check if children under general anesthesia need extra fluids. It aims to find a better way to manage fluid balance during surgery.
