Purpose of review Spontaneous intracerebral hemorrhage (ICH) is the deadliest stroke subtype. Acute treatments necessitate rapid hemorrhage control to minimize secondary brain injury. Here, we discuss the overlap of transfusion medicine and acute ICH care relating to diagnostic testing and therapies relevant for coagulopathy reversal and secondary brain injury prevention. Recent findings Hematoma expansion (HE) is the largest contributor to poor outcomes after ICH. Conventional coagulation assays to diagnose coagulopathy after ICH does not predict HE. Given the testing limitations, empiric pragmatic hemorrhage control therapies have been trialed but have not improved ICH outcomes, with some therapies even causing harm. It is still unknown whether faster administration of these therapies will improve outcomes. Alternative coagulation tests (e.g., viscoelastic hemostatic assays, amongst others) may identify coagulopathies relevant for HE, currently not diagnosed using conventional assays. This provides opportunities for rapid, targeted therapies. In parallel, ongoing work is investigating alternative treatments using transfusion-based or transfusion-sparing pharmacotherapies that can be implemented in hemorrhage control strategies after ICH. Summary Further work is needed to identify improved laboratory diagnostic approaches and transfusion medicine treatment strategies to prevent HE and optimize hemorrhage control in ICH patients, who appear particularly vulnerable to the impacts of transfusion medicine practices.
