Can the change in internal jugular vein collapsibility from before to just after anesthesia predict low blood pressure during surgery and acute kidney injury after surgery?\n\nParticipants will have routine ultrasound scans of the neck before anesthesia and again shortly after they fall asleep for surgery.
