Fresh Frozen Plasma in Cardiac Surgery: Descriptive and Prognostic Study

Background

Fresh frozen plasma (FFP) transfusions recommendations are essentially based on experts' opinions. However, disparity in consumption of FFP by cardiac surgery centers in France probably reflects heterogeneous practices that are not well characterized. Furthermore, health outcomes of these strategies on morbidity and mortality are not documented.

Objectives

Primary: to describe transfusional strategies of FFP in patients undergoing cardiac surgery and either presenting a serious bleeding during pre, per or post-operative periods or transfused by FFP without a serious bleeding.

Secondary:

• To estimate the conformity of transfusion or lack of transfusion of FFP to French authorities recommendations.
• To describe the post-operative mortality and morbidity.
• To evaluate the prognostic role of FFP transfusion on mortality and morbidity

Study design

Prospective prognostic cohort study, with an exhaustive recruitment in participating cardiac surgery centers during the study period.

Eligibility criteria

Centers: 16 French cardiac surgery centers.

Patients:

• Coronary artery bypass grafting (CABG), valvular replacement, surgery for thoracic aorta aneurysm or dissection, heart graft.
• Serious bleeding or FFP transfusion during pre, per or post-operative period.
• Patient's consent for collecting medical data

Analysis

Descriptive analysis of transfusional strategies according to patients' characteristics, type of surgery and circumstances of transfusions.

Conformity to French authorities' current recommendations. Multivariate analysis of the prognostic role of FFP transfusion on 30-day mortality.

Inclusion criteria

• Coronary artery bypass grafting (CABG), valvular replacement, surgery for thoracic aorta aneurysm or dissection, heart graft.
• Serious bleeding or FFP transfusion during pre, per or post-operative periods.
• Patient's consent for collecting medical data

Exclusion criteria

• Congenital heart disease
