Sepsis Management in Pneumonia

Recognition and Initial Management

  • The Society of Critical Care Medicine recommends that septic shock be recognized when there is suspected or confirmed infection, and despite full fluid resuscitation, vasopressors are required to maintain a mean arterial pressure (MAP) ≥65 mmHg with lactate ≥2 mmol/L 2, 3, 4
  • If lactate cannot be measured, consider three manifestations: changes in mental status, oliguria, and poor peripheral perfusion with prolonged capillary refill time 2, 3

Antibiotic Therapy

  • The European Society of Intensive Care Medicine recommends administering broad-spectrum intravenous antibiotics within the first hour of septic shock recognition, using empirical combination therapy with at least two different classes of antimicrobials that cover all likely pathogens, including gram-negative and gram-positive bacteria 1
  • Obtain microbiological cultures (including at least two sets of aerobic and anaerobic blood cultures) before starting antimicrobials, but this should not delay the initiation of antibiotics 1

Fluid Resuscitation and Vasopressors

  • The Society of Critical Care Medicine recommends administering at least 30 mL/kg of isotonic crystalloids in the first 3 hours in adults 2, 3, 4
  • Use isotonic crystalloid solutions for resuscitation 2, 3
  • When septic shock persists after fluid resuscitation, administer norepinephrine as the first-choice vasopressor 2, 3, 4

De-escalation and Duration of Treatment

  • The European Society of Intensive Care Medicine recommends that combination empirical therapy should not be administered for more than 3-5 days 1, 5
  • De-escalation to the most appropriate single therapy should be done as soon as the susceptibility profile is known 1, 5
  • The typical duration of treatment is 7-10 days 1, 5

Supportive Care in ARDS

  • If pneumonia progresses to acute respiratory distress syndrome (ARDS), adopt conservative fluid management in patients with ARDS without tissue hypoperfusion 2, 3, 4
  • Avoid routine use of corticosteroids unless there are special reasons 2, 3, 4

Common Pitfalls to Avoid

  • Never delay antibiotics while waiting for cultures 1
  • The initial empirical coverage should be sufficiently broad 1, 5
  • Aggressively de-escalate based on cultures and clinical improvement 1, 5
