Sepsis 6

The “Sepsis Six” is a bundle of medical therapies designed to reduce the mortality of patients with sepsis. Early intervention is critical in sepsis management to improve outcomes, and the Sepsis Six provides a straightforward and immediate approach that can be implemented within the first hour of recognizing sepsis.

The Sepsis Six bundle comprises three diagnostic and three therapeutic steps:

Diagnostic Steps:

  1. Blood cultures:
    • Before starting antibiotics, obtain blood samples to identify the causative organism.
  2. Lactate for acidosis, FBC, U&E, CRP, INR:
    • Provides insights into the patient’s physiological response, renal and liver function, electrolyte balance, and other parameters.
  3. Urine output measurement:
    • Either by ensuring a catheter is inserted or measuring output in another way, as renal function can be compromised in sepsis.

Therapeutic Steps:

  1. Intravenous (IV) antibiotics:
    • Administer broad-spectrum antibiotics within 1 hour of sepsis recognition, with adjustments made later based on culture results and clinical status.
  2. IV fluid resuscitation:
    • Provides rapid fluid resuscitation to improve perfusion and organ function (20ml/kg in children if lactate > 2)
  3. Administer high-flow oxygen:
    • To maintain oxygen saturation >94% or >88-92% in patients with risk of hypercapnic respiratory failure.

Implementing the Sepsis Six protocol within the first hour of diagnosing sepsis has been associated with reduced mortality. It offers a structured initial response to a complex condition that requires prompt action. However, individual patient needs may vary, and clinical judgment remains essential.

Further Management

Additional investigations may be performed depending on the suspected infection:

  • Chest xray if pneumonia is suspected
  • Abdominal and pelvic ultrasound if intra-abdominal infection is suspected
  • Lumbar puncture if meningitis is suspected
  • Meningococcal PCR blood test if meningococcal disease is suspected
  • Serum cortisol if adrenal crisis is suspected
