Video Summary

A 27-year-old ICU patient with flu-induced ARDS on heparin for DVT develops severe thrombocytopenia and bleeding. Differential diagnoses include drug-induced thrombocytopenia, heparin-induced thrombocytopenia (HIT), sepsis, and autoimmune causes. The best immediate step is stopping heparin while awaiting HIT testing. Diagnosing HIT is complex, requiring clinical judgment and hematology consultation. Immune thrombocytopenia (ITP) is an autoimmune platelet disorder triggered by infections or malignancy, diagnosed by exclusion. Treatment begins with steroids and IVIG, advancing to thrombopoietin receptor agonists if needed. Expert hematology input is crucial for managing thrombocytopenia causes and treatment.
