Predicting low blood pressure after anesthesia in older patients
Part of Heart & circulation clinical trials.
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.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are 60 years or older (geriatric) and having planned (elective) surgery with general anesthesia.
- You have a normal health status (ASA class I or II) – for example, no serious heart or lung disease.
- You have not eaten or drunk anything for at least 6 to 8 hours before surgery.
- Your body mass index (BMI) is 30 or less.
- You do not have a history of peripheral artery disease, atherosclerosis, arrhythmia, cardiomyopathy, or chronic obstructive pulmonary disease (COPD).
- Your blood pressure before surgery is between 90 and 180 mmHg (systolic).

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.
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 a special blood pressure monitoring tool (called PPV) can help predict a condition called pregnancy-induced hypertension (high blood pressure during pregnancy) in older patients. If you are 65 or older and having planned surgery with an arterial line, you may be eligible to join.
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 tests a computer model that uses heart-rhythm measurements to predict whether your blood pressure will drop dangerously after anesthesia begins. If accurate, it could help doctors prepare and protect you during surgery.
