Low blood pressure after anesthesia in older cancer surgery patients

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.

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 how blood pressure medications affect low blood pressure episodes that happen during and after heart surgery. Researchers want to understand if the number of blood pressure drugs you take before surgery changes how your body handles blood pressure during the operation.

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 looks at whether people who have low blood pressure after eating are also more likely to have low blood pressure after starting general anesthesia. It may help doctors better predict and manage blood pressure drops during non-heart surgeries in older adults.

This study looks at how often low blood pressure happens after surgery in the recovery room. It helps doctors understand and better manage blood pressure in patients who just had general anesthesia.
