Explanation

Core Concept: Heparin is an anticoagulant that accelerates the action of antithrombin III, inhibiting thrombin and factor Xa. In cases of severe bleeding or overdose, a specific reversal agent is required.

Clinical Presentation:

  • Bleeding, bruising, hematuria, or prolonged aPTT.

Diagnosis:

  • *First-line:* Coagulation profile (prolonged aPTT).
  • *Gold Standard:* Clinical correlation with active bleeding.

Management:

  • *Acute:* Administer *Protamine sulfate*, which is a positively charged molecule that binds to the negatively charged heparin to form a stable, inactive complex, rapidly reversing its anticoagulant effect.
  • *Definitive:* Monitor aPTT and clinical signs of bleeding; adjust or discontinue heparin therapy.
