Comparison of Thromboelastography Devices TEG6S Point of Care Device vs. TEG5000 in Pediatric Patients Undergoing Cardiac Surgery.

Thromboelastography (TEG) can predict bleeding in pediatric patients undergoing cardiac surgery. We hypothesized that results obtained from TEG5000 correlate with the new point-of-care TEG6S system and that TEG6S rewarming maximum amplitude (MA) is associated with surrogate endpoints for perioperative bleeding in pediatric patients who underwent complex cardiac surgery. We describe a retrospective study of pediatric (≤18 years) patients who underwent complex cardiac surgery on cardiopulmonary bypass.

Thromboelastography During Rewarming for Management of Pediatric Cardiac Surgery Patients.

Background: Thromboelastography (TEG) predicts bleeding in pediatric patients undergoing cardiac surgical procedure. We hypothesize that TEG indicators at rewarming correlate with postprotamine values and that rewarming TEG is associated with surrogate end points for postoperative bleeding in pediatric patients undergoing complex cardiac surgical procedure.

Methods: In a retrospective study of 703 pediatric (≤18 years) patients undergoing complex cardiac surgical procedures, TEG results obtained during rewarming and after protamine administration were compared using linear regression.
