Management of Septic Shock in the ICU
Initial Resuscitation
- The Society of Critical Care Medicine recommends beginning treatment immediately upon recognition of septic shock, as it is a medical emergency, with aggressive fluid resuscitation (at least 30 mL/kg IV crystalloids within 3 hours) and broad-spectrum antibiotics within 1 hour of recognition 1, 2
- Administer at least 30 mL/kg of IV crystalloid fluid within the first 3 hours, as recommended by the European Society of Intensive Care Medicine 1, 2, 3
- Target mean arterial pressure (MAP) ≥65 mmHg, as recommended by the American College of Critical Care Medicine 2, 3
- Monitor urine output (target ≥0.5 mL/kg/hour), heart rate, blood pressure, oxygen saturation, respiratory rate, temperature, and mental status, as recommended by the Society of Critical Care Medicine 2
- Consider lactate normalization as a resuscitation target in patients with elevated lactate levels, as recommended by the European Society of Intensive Care Medicine 2
Vasopressor and Inotropic Support
- Use norepinephrine as the first-choice vasopressor to maintain MAP ≥65 mmHg, as recommended by the American College of Critical Care Medicine 3
Mechanical Ventilation
- Use low tidal volumes (6 mL/kg predicted body weight) in all ARDS patients, as recommended by the American Thoracic Society 5, 3
- Maintain plateau pressure ≤30 cm H2O, as recommended by the European Society of Intensive Care Medicine 3
- Use higher PEEP strategies in moderate-to-severe ARDS, as recommended by the American Thoracic Society 5, 3
- Consider prone positioning for patients with PaO2/FiO2 <150 mmHg, as recommended by the European Society of Intensive Care Medicine 5, 3
Supportive Care Measures
- Use protocolized insulin therapy when two consecutive blood glucose levels are >180 mg/dL, as recommended by the American Diabetes Association 7, 8, 9, 6
- Target upper blood glucose ≤180 mg/dL, NOT ≤110 mg/dL (tight control increases harm), as recommended by the American College of Critical Care Medicine 7, 8, 6, 3
- Avoid routine pulmonary artery catheter use, as recommended by the Society of Critical Care Medicine 7, 8, 9
- Do not use β-2 agonists for sepsis-induced ARDS without bronchospasm, as recommended by the American Thoracic Society 7, 8, 9, 5
Transfusion Thresholds
- Target hemoglobin 7-9 g/dL unless active myocardial ischemia present, as recommended by the American College of Critical Care Medicine 3
