A person with multiple injuries develops fever tachycardia tachypnea and a periumbilical rash. Diagnosis is?

c. Symptoms typically begin 1 to 3 days after injury, with sudden onset of tachypnea, dyspnea, and tachycardia.
d. Neurologic symptoms include irritability and restlessness, with progression to delirium or coma.
e. Patients may present with thrombocytopenia, presumably caused by platelets adhering to the myriad fat globules and begin removed from the circulation; anemia may result as a consequence of erythrocyte aggregation and hemolysis.
f. A diffuse petechial rash in nondependent areas (related to rapid onset of thrombocytopeniA. is seen in 30% to 50% of cases and is useful in establishing a diagnosis.
