Mortality is high in intracranial hemorrhage, and even higher for anti-platelet associated ICH (AP-ICH). The Platelet Transfusion Versus Standard Care After Acute Stroke Due to Spontaneous Cerebral Hemorrhage Associated with Antiplatelet Therapy (PATCH) trial was shocking: it demonstrated platelet transfusion was associated with worse outcomes, excluding those patients who were planned to go to surgery in the next 24 hours. SCCM and the Neurocritical Care Society recommend AGAINST platelet transfusion in non-operative ICH, but encourage a dose of DDAVP.
But who knows who will go to surgery? If you've been giving platelets and DDAVP to non-operative AP-ICH, you're not alone. So in the July Issue of Crit Care Medicine, the authors of the PATCH trial published a retrospective study of 140 patients, excluding those who immediately had surgery. In this group in which a quarter eventually had decompressive craniectomy and a fifth had an external ventricular drain placed, half received platelets and DDAVP instead of DDAVP alone.
The result? Still no benefit to platelet transfusion (despite the inclusion of patients who went on to have surgery). We all WANT to give platelets to AP-ICH, but there is NO evidence of BENEFIT and we may cause HARM. A test of platelet function (like the TEG) should be performed at the very least to select for patients with actual platelet dysfunction, and transfusion should be limited to patients going to surgery.
