Clinical question: What is the recommended approach to platelet transfusion in several common clinical scenarios?
Background: The AABB (formerly American Association of Blood Banks) developed these guidelines from a recent systematic review on platelet transfusion.
Synopsis: One strong recommendation was made based on moderate-quality evidence. Four weak or uncertain recommendations were made based on low- or very low-quality evidence.
For hospitalized patients with therapy-induced hypoproliferative thrombocytopenia, transfusion of up to a single unit of platelets is recommended for a platelet count of 10x109 cells/L or less to reduce the risk of spontaneous bleeding (strong recommendation, moderate-quality evidence).
For patients undergoing elective central venous catheter placement, platelet transfusion is recommended for a platelet count of less than 20x109 cells/L (weak recommendation, low-quality evidence).
For patients undergoing elective diagnostic lumbar puncture, platelet transfusion is recommended for a platelet count of less than 50x109 cells/L (weak recommendation, very low-quality evidence).
For patients undergoing major elective non-neuraxial surgery, platelet transfusion is recommended for a platelet count of less than 50x109 cells/L (weak recommendation, very low-quality evidence).
For patients undergoing cardiopulmonary bypass surgery, it is recommended that surgeons not perform routine transfusion of platelets in non-thrombocytopenic patients. For patients who have peri-operative bleeding with thrombocytopenia and/or evidence of platelet dysfunction, platelet transfusion is recommended (weak recommendation, very low-quality evidence).
There is insufficient evidence to recommend for or against platelet transfusion in patients with intracranial hemorrhage who are taking antiplatelet medications (uncertain recommendation, very low-quality evidence).
