Objectives

Narrative objectives1

This study aims to evaluate whether fibrinogen levels and platelet counts measured immediately after separation from cardiopulmonary bypass are associated with time to surgical completion. The association between these hemostatic parameters and post-bypass blood loss will also be investigated.

Key inclusion criteria

Adult patients undergoing cardiovascular surgery with cardiopulmonary bypass through a median sternotomy.
Patients in whom both fibrinogen level and platelet count were measured within 30 minutes after separation from cardiopulmonary bypass.
