Approach to Thrombocytopenia in ICU

Thrombocytopenia frequently occurs in patients who are in the intensive care unit (ICU). It can arise from a variety of causes including pseudothrombocytopenia, dilution of blood, heightened platelet use, reduced platelet production, enhanced platelet sequestration, and immune-related thrombocytopenia, either individually or through a combination of factors. To diagnose and prognosticate thrombocytopenia in critically ill individuals, it is essential to start with a thorough review of the patient’s historical health records and symptoms at presentation. This background, along with a detailed examination of changes in platelet counts in relation to the patient’s ongoing clinical status and targeted laboratory tests, provides valuable insights.
