Predicting low blood pressure in liver disease patients after anesthesia
Part of Blood & lymphatic, Heart & circulation clinical trials.
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.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are 18 years or older and have a chronic liver disease, such as cirrhosis.
- You are scheduled for a planned (not emergency) surgery that requires general anesthesia.
- You are considered an ASA class 2, 3, or 4 (a rating of your overall health before surgery) — if you are class 4, your starting blood pressure must be above 65 mmHg.
- You do not have a known heart problem (like severe valve disease or heart failure) or a history of neck surgery or injury.
- You are not taking certain blood pressure pills (ARBs or ACE inhibitors) by mouth, and your body mass index (BMI) is between 15 and 30.
- Your surgery will not be done while you are lying on your side, front, or in a feet-up position.

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 checks if a simple ultrasound test of the heart can predict whether your blood pressure will drop when you go under general anesthesia. If your blood pressure is likely to drop, your care team can be ready to manage it, making your anesthesia safer.
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 checks if a simple ultrasound of the neck's blood vessels can predict a sudden drop in blood pressure when you go under general anesthesia for a non-heart surgery. It may help doctors prevent and manage low blood pressure during procedures.
This study tests whether a simple leg-raising test during ultrasound of the neck arteries can predict if blood pressure will drop after anesthesia starts. This could help doctors prevent dangerous drops in blood pressure during surgery.
