Use of ROTEM for Multi-level Spine Surgery (ROTEM)

This study has been completed.

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.


Study Type: Observational
Study Design: Observational Model: Case-Only
Time Perspective: Prospective
Official Title: A Prospective Observational Study to Evaluate Perioperative Coagulation Profiles Using Rotational Thromboelastometry (ROTEM®) in Patients Undergoing Multi-level Spine Surgery

Further study details as provided by Hugh Hemmings, Weill Medical College of Cornell University:

Primary Outcome Measures:
  • 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.

Enrollment: 41
Study Start Date: February 2009
Study Completion Date: December 2011
Primary Completion Date: December 2010 (Final data collection date for primary outcome measure)
