Blood flow monitoring during day-case knee 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 tests a technique called controlled hypotension, where your blood pressure is intentionally lowered during spinal surgery to reduce bleeding. The goal is to see if this method makes surgery safer and improves recovery.

This study looks at whether a simple ultrasound measurement of blood flow in your neck can help predict if your blood pressure might drop during spinal anesthesia for a C-section. This could help doctors prevent dizziness and other side effects.

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 tests whether an AI tool can help doctors better manage low blood pressure during planned surgeries. If you are having an elective surgery with general anesthesia and need an arterial line for monitoring, this trial may be for you.

This trial looks at how a breathing maneuver during surgery can safely lower blood pressure and help doctors decide whether you need extra fluids. It may help guide your care during surgery to keep you stable and reduce complications.
