Using vein size to predict blood pressure drops in older adults during hip or leg surgery
Part of Bones, joints & muscles, Heart & circulation clinical trials.
This study uses an ultrasound to measure the size of a vein in your leg before surgery to see if it can predict a drop in blood pressure during the procedure. If you are over 60 and having planned lower-limb surgery with spinal anesthesia, this non-invasive test might help your doctors prepare for your care.
Summary written for real people, not researchers, by Clin2.

This study tests whether checking how much the jugular vein (a vein in the neck) collapses can help predict drops in blood pressure during surgery. It's for older adults having laparoscopic colon or rectal surgery.
This study uses ultrasound to look at a vein in your neck before and after major abdominal surgery to understand how surgery affects your kidneys. Researchers hope this simple imaging technique might help predict and prevent kidney problems after surgery.
This study looks at whether using ultrasound to check the neck arteries before surgery can help doctors predict and prevent low blood pressure during hip replacement surgery done with spinal anesthesia. If you are 65 or older and having this surgery, this could help make your procedure safer.
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 trial uses ultrasound to check your internal jugular vein, which may help predict if your blood pressure will drop during spinal anesthesia. It aims to find better ways to keep you safe during surgery.
This study looks at whether a simple ultrasound of a neck vein can help predict if your blood pressure will drop too low during spinal anesthesia for your C-section. The goal is to make delivery safer and more comfortable for you and your baby.
