What is the primary goal of DVT prophylaxis in ICU patients?

• A. Prevent venous thromboembolism; start early unless contraindicated.
• B. Decrease blood pressure variability
• C. Improve oxygen delivery by increasing hemoglobin
• D. Increase survival by reducing infection

Answer: (A)

Preventing venous thromboembolism in critically ill patients is the main aim of DVT prophylaxis. ICU patients are at high risk for clot formation because of immobility, systemic illness, and invasive devices, and a deep vein thrombosis can progress to a potentially fatal pulmonary embolism. The approach is to start preventive measures as early as safely possible unless there is a contraindication such as active bleeding or severe thrombocytopenia. Prophylaxis typically combines pharmacologic options (like low-dose heparin or low-molecular-weight heparin) with mechanical methods (such as compression devices) when anticoagulation is not appropriate. By lowering the incidence of DVT and PE, this strategy helps reduce morbidity and improve outcomes. Other options mentioned do not address clot prevention and thus are not the primary goal of DVT prophylaxis.
