Bedside Reasoning

Heart failure · Shock · Sepsis · DIC — five steps each. See it, understand it, connect it, act on it, apply it.

04 · Disseminated Intravascular Coagulation — Step 01 of 05 · See it

Both faces at once

DIC shows thrombosis and bleeding simultaneously. When a septic or traumatized patient starts doing both, think DIC.

The clotting face

  • • Microvascular thrombosis and ischemia
  • • Mottled, dusky extremities
  • • Worsening organ dysfunction

The bleeding face

  • • Oozing from lines and puncture sites
  • • Ecchymosis and expanding bruises
  • • Mucosal or wound bleeding

Common triggers

  • Sepsis / severe infection
  • Trauma and massive tissue injury
  • Malignancy, especially acute promyelocytic leukemia
  • Obstetric catastrophes (abruption, amniotic fluid embolism, HELLP)
  • Severe pancreatitis
  • Transfusion reactions and hemolysis
  • Vascular catastrophes (aortic aneurysm, giant hemangioma)
