Severe bleeding related to cardiac surgery is associated with increased morbidity and mortality. Thromboelastography (TEG) and thromboelastometry (ROTEM) are point-of-care tests (POCT). Bedside ROTEM/TEG can rapidly detect changes in blood coagulation and therefore provide a goal-directed, individualized coagulation therapy. In this meta-analysis, we aimed to determine the current evidence for or against POCT-guided algorithm in patients with severe bleeding after cardiac surgery.
