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

Evaluation of the Use of Arterial Pulse Waveform Contour Analysis for Goal Directed Therapy in Patients Undergoing 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.

Inclusion Criteria:

• Adult patients scheduled for major spine surgery at LLUMC University Hospital will be eligible for participation in this study

Exclusion Criteria:

• age under 18yr,
• coagulopathy, significant renal or hepatic dysfunction (creatinine or liver enzymes > 50% above normal values),
• congestive heart failure,
• cardiac arrhythmias producing irregular rhythms, and patient refusal.
