Arterial Pulse Waveform Contour Analysis for Intraoperative Goal Directed Therapy in Major Spine Surgery

This study evaluates whether using information from a special arterial blood pressure
monitor to guide how much fluid is given during surgery changes how long a patient stays in
the hospital after the surgery. There is scientific evidence from using similar information
from different devices that this technique might allow us to do a better job giving fluids
during surgery and that this may be associated with a shorter hospital stay after surgery.
