Nomogramas iniciales de warfarina para tromboembolismo venoso

Resumen

Venous thromboembolism (VTE) is a common condition in hospital patients. Considerable controversy is ongoing regarding optimal initial warfarin dosing for patients with acute deep venous thrombosis (DVT) and pulmonary embolism (PE). Achieving a therapeutic international normalized ratio (INR) with warfarin as soon as possible is important because this minimizes the duration of parenteral medication necessary to attain immediate anticoagulation, and it potentially decreases the cost and inconvenience of treatment. Although a 5mg loadingdose nomogram tends to prevent excessive anticoagulation, a 10mg loadingdose nomogram may achieve a therapeutic INR more quickly.
