Measurements of platelet aggregation with the agonists adenosine diphosphate (ADPtest), arachidonic acid (ASPItest) and thrombin-receptor-agonist-peptide-6 (TRAPtets) from 100 patients on days 1 ± 1 (n = 87), 4 ± 1 (n = 74), 7 ± 1 (n = 44), and 14 ± 2 (n = 11) after initiation of extracorporeal membrane oxygenation therapy. Day 1* excluding patients treated with ADP inhibitor (n = 13), with platelet count < 100 × 109/L (n = 25) or both (n = 4). Day 1** excluding patients treated with acetylsalicylic acid (n = 14), with platelet count < 100 × 109/L (n = 23) or both (n = 6). Day 1*** excluding patients with platelet count < 100 × 109/L (n = 29).
