Brief Summary:
The purpose of this study is to obtain coagulation profiles of patients undergoing multi-level spine surgeries with ROTEM® and routine coagulation tests. The investigators will compare the data from ROTEM® and routine coagulation tests with each other and with blood loss and transfusion therapies used.

Patients undergoing multi-level spine surgery

Primary Outcome Measures :
  1. Coagulation profiles. [ Time Frame: One measurement before surgery, one after surgery is completed, and one measurement at each i-stat or 10% total blood volume loss. ]

Biospecimen Retention:   Samples With DNA
a small sample of blood will be obtained from a pre-existing arterial line.
