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 trial is testing a way to keep blood pressure lower on purpose during spinal surgery. This might help reduce blood loss and the need for blood transfusions during the operation. If you are having a specific type of spinal surgery and are generally healthy, you may be a good fit.

This trial uses an ultrasound measurement of blood flow in the neck to predict if a pregnant woman will experience low blood pressure after receiving spinal anesthesia for a C-section. This could help doctors take steps to prevent it.

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 tests a new, non-invasive way to predict drops in blood pressure during major hip, knee, pelvis, or spine surgery. The goal is to help doctors prevent low blood pressure, which can lead to complications.
