Thrombus formation (compromising blood supply to various organs) Exhaustion of platelets and coagulation factors (as results of the overwhelming clot formation) Brief period of hyper coagulation: coagulation cascade is initiates. Causing widespread fibrin formation: micro thrombi are deposited. Throughout microcirculation: fibrin deposit result in tissue. Ischemia, hypoxia, necrosis: leads to multi organ dysfunction. Gi: excreta for melena, hematemesis, stool testing occult blood. Q 2h prn t&p pt (pu, statis, clotting risk) Ambulatory, assist x1 (fall, bump and bruising risk) O2: presence of sob, cyanosis, colour, anxiety and restlessness.
