Thromboelastography in guiding preventive platelet transfusion in patients with haematologic diseases.

Objective: This study analysed the relationships between the main thromboelastography (TEG) parameters, the platelet (PLT) count and clinical bleeding in patients with blood diseases. We explored the threshold of the relevant parameters in the pathological condition of bleeding, aiming to scientifically guide clinical prophylactic PLT transfusion.

Methods: In total, 268 patients with clear diagnoses of blood diseases and thrombocytopenia were enrolled and divided into five groups, A, B, C, D and E, corresponding to PLT counts of 0-10 × 10 /L, 11-20 × 10 /L, 21-30 × 10 /L, 31-50 × 10 /L and 51-100 × 10 /L, respectively.
