Neck vein test to predict blood pressure drop during surgery
Part of Heart & circulation clinical trials.
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.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You must be 60 years old or older.
- You must be scheduled for laparoscopic (keyhole) surgery on your colon or rectum under general anesthesia.
- You must not have severe aortic stenosis (a heart valve problem).
- You must not have a very irregular heartbeat (like atrial fibrillation or constant extra beats).
- You must be able to safely have your legs lifted while lying down (passive leg raise) during the study.

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 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 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 new tool that warns doctors when your blood pressure might drop during lung surgery. If it works well, it could help prevent complications and keep you safer during the operation.
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.
This study looks at how the size and collapsibility of a vein in the neck changes after spinal anesthesia for cesarean section. It compares women with preeclampsia (high blood pressure during pregnancy) to healthy women to see if this vein measurement can help predict who might have low blood pressure after the anesthesia.
