Predicting low blood pressure during gastrointestinal tumor surgery
This study tests whether a simple ultrasound of the neck's blood vessels, combined with a leg-raising maneuver, can help predict low blood pressure after you go under anesthesia for gastrointestinal tumor surgery. It aims to make anesthesia safer and more personalized.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are 18 years or older.
- You are scheduled for elective (non-emergency) surgery to remove a gastrointestinal tumor.
- Your surgery will be done under general anesthesia.
- You do not have certain severe heart, lung, or vascular conditions.
- You are not pregnant, not having an emergency surgery, and your blood pressure is within a certain range.

This study looks at what causes low blood pressure after anesthesia starts in older patients with cancer who are having surgery. It may help doctors prevent complications.
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 trial tests if noninvasive blood pressure cuff measurements before surgery can help predict low blood pressure during surgery for people having non-cardiac surgery.
This study looks at whether an ultrasound of the carotid artery in your neck, done before surgery, can help predict drops in blood pressure after you go to sleep for your operation. The goal is to improve safety for patients having non-cardiac surgery.
This trial is looking at whether two simple ultrasound measurements can better predict if a patient's blood pressure will drop after anesthesia begins during surgery for an intestinal blockage. This could help doctors keep patients safer during surgery.
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.
