FGA and Pulmonary hemorrhage: Hemocoagulase, a thrombin-like enzyme, releases fibrinopeptide A, which forms fibrin clots.[1] It reduces the bleeding time and transfusion requirements in patients undergoing surgery or with trauma.[2,4] In addition, hemocoagulase administration in critical neonates reduces pulmonary hemorrhage and mortality.[8,9] In patients with pulmonary hemorrhage, hemocoagulase can be used as a systemic hemostatic drug.[5,7]
