Thrombocytopenia in the Surgical Intensive Care Unit
Thrombocytopenia is the most prevalent hematologic disorder in the ICU. Defined as a as a platelet count ≤150 × 109/L, thrombocytopenia is observed in 30–50 % of critically ill patients . The consequences of thrombocytopenia range from a mild, asymptomatic phenomenon to microvascular failure. A drop in platelet count by >30 % is an independent risk factor for death and a stronger predictor of mortality than the Acute Physiology and Chronic Health Evaluation (APACHE) II score [2, 3]. Multiple etiologies may contribute to a low platelet count. This chapter will specifically review the diagnosis and management of thrombocytopenia in the surgical ICU patient.
