Questions and Answers

What is a common physiological sign of poor organ perfusion that can be a historical harbinger of low blood flow?

  • Gut dysbiosis
  • Acute kidney injury (correct)
  • Hypotension
  • Tachycardia

What is the range of in-hospital mortality associated with progression to septic shock?

  • 20% to 30%
  • 50% to 75%
  • 5% to 10%

Study Notes

Early Recognition and Diagnosis of Septic Shock

  • Other physiological signs of poor organ perfusion can serve as historical indicators of low blood flow or predictors of discharge with an arrhythmic event.
  • Acute kidney injury, characterized by a creatinine level >2 mg/dL, is a key indicator of poor organ perfusion.
  • Progression to septic shock is associated with an in-hospital mortality ranging from 12.5% to 49.7%.
  • It is essential to differentiate between community-acquired septic shock, healthcare-acquired septic shock, and hospital-acquired septic shock, as the causative bacteria may differ.
  • Identifying the bacteria causing the septic shock informs the choice of empirical broad-spectrum antibiotic therapy.
  • Recent treatment with antibiotics, such as amoxicillin or macrolides, may have eradicated vaginal bacterial anaerobes, leading to gut dysbiosis and bacteremias.

Diagnostic Criteria for Septic Shock

  • Septic shock diagnosis requires recognition of systemic infection and clinical signs of substantial tissue perfusion abnormalities.
  • The American College of Chest Physicians/Society of Critical Care Medicine (ACCP/SCCM) diagnostic criteria for septic shock, known as 'Sepsis-2', include:
    • Acute organ dysfunction
    • Hypotension (systolic arterial pressure <90 mmHg or a decrease of ≥40 mmHg from baseline)
    • Additional clinical or laboratory evidence of acute organ dysfunction
