Neck Vein Ultrasound and Kidney Function After Abdominal Surgery
Part of Kidney & urinary, Women’s health & pregnancy clinical trials.
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.
Summary written for real people, not researchers, by Clin2.
Who can take part
- Planned (elective or urgent) major abdominal surgery lasting more than 1 hour under general anesthesia
- General anesthesia started with propofol (a common IV medication)
- Blood pressure monitored continuously during surgery with either an arterial line or regular cuff
- Recent kidney function test results (blood creatinine and eGFR) from the past 30 days
- Ability to be reached by phone 30 days after surgery
- Willingness to sign written consent before surgery

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 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.
This study tests an ultrasound method to help place a line in the neck vein while you’re under general anesthesia. It mainly aims to improve how safely and accurately the line is positioned.
This trial looks at the best spot to place an internal jugular (neck) catheter when you are having surgery under general anesthesia. It may help make catheter placement safer and more comfortable by comparing techniques.
This study tests whether an ultrasound measurement of a vein in your neck can predict whether your blood pressure will drop during gallbladder removal surgery. If successful, doctors could use this quick scan to identify patients at risk and take preventive steps.
This trial tests a new way to manage fluids during abdominal surgery by using ultrasound to check the internal jugular vein in your neck. The goal is to see if this approach reduces complications after surgery.
