Sepsis Management Guidelines
Initial Assessment and Diagnosis
- The American College of Critical Care Medicine recommends obtaining at least two sets of blood cultures before starting antimicrobial therapy, as long as this doesn't delay treatment >45 minutes 1
- A thorough clinical examination and imaging studies should be performed promptly to identify the source of infection, as suggested by the European Society of Intensive Care Medicine 3
- Measure serum lactate levels as a marker of tissue hypoperfusion, according to the Surviving Sepsis Campaign 1
- Monitor hourly urine output, lactate levels, and biochemical markers of renal function as indicators of microvascular perfusion, as recommended by the Society of Critical Care Medicine 4
Immediate Resuscitation
- Administer intravenous antimicrobials within one hour of recognizing septic shock and severe sepsis, as recommended by the Infectious Diseases Society of America 1, 2
- Provide aggressive fluid resuscitation with crystalloids and/or colloids for patients with tissue hypoperfusion, according to the European Society of Intensive Care Medicine 4, 3
- Initial fluid resuscitation with 30 mL/kg of crystalloid for hypotension or lactate ≥4 mmol/L, as suggested by the Surviving Sepsis Campaign 1
- More than 4 L during the first 24 hours may be required to adequately resuscitate the adult septic patient, as recommended by the Society of Critical Care Medicine 5
Hemodynamic Support
- Target a mean arterial pressure (MAP) of at least 65 mmHg in patients requiring vasopressors, according to the American College of Critical Care Medicine 1, 2
- Use norepinephrine as the first-choice vasopressor to maintain adequate blood pressure, as recommended by the European Society of Intensive Care Medicine 1
- Consider epinephrine when an additional agent is needed to maintain adequate blood pressure, as suggested by the Surviving Sepsis Campaign 1
- Vasopressin (0.01-0.04 units/min) or terlipressin (boluses of 1-2 mg) can be added as rescue therapies in cases of refractory shock, according to the Society of Critical Care Medicine 4, 1
Respiratory Management
- Apply oxygen to achieve an oxygen saturation >90%, as recommended by the European Society of Intensive Care Medicine 3, 1
- Place patients in a semi-recumbent position (head of bed elevated 30-45°), according to the American Thoracic Society 3, 1
- Consider non-invasive ventilation for patients with dyspnea and/or persistent hypoxemia despite oxygen therapy, as suggested by the European Society of Intensive Care Medicine 3, 6
- For patients with sepsis-induced ARDS, use low tidal volume ventilation (6 mL/kg predicted body weight), as recommended by the Surviving Sepsis Campaign 1
Antimicrobial Management
- Administer broad-spectrum antimicrobials with activity against all likely pathogens, according to the Infectious Diseases Society of America 1, 2
- Reassess antimicrobial regimen daily for potential de-escalation, as recommended by the Surviving Sepsis Campaign 1
- Consider combination empirical therapy for neutropenic patients and for difficult-to-treat, multidrug-resistant pathogens, as suggested by the Infectious Diseases Society of America 1
Source Control
- Identify and control the source of infection as rapidly as possible, according to the European Society of Intensive Care Medicine 3, 1
- Drain or debride the source of infection whenever possible, as recommended by the Society of Critical Care Medicine 3, 6
- Remove any foreign body or device that may potentially be the source of infection, according to the Infectious Diseases Society of America 3, 6
Blood Product Therapy
- In the case of acute anemia, target a hemoglobin between 8 and 9 g/dl, as recommended by the American Association of Blood Banks 4
- Consider different hemoglobin targets based on clinical tolerance or vena cava oxygen saturation (SvcO2), according to the Society of Critical Care Medicine 4
Metabolic Management
- Use a protocolized approach to blood glucose management, targeting an upper blood glucose level ≤180 mg/dL, as recommended by the American Diabetes Association 1, 2
- Monitor blood glucose every 1-2 hours until glucose values and insulin infusion rates are stable, then every 4 hours, according to the Surviving Sepsis Campaign 1, 2
- Avoid hypoglycemia, as suggested by the European Society of Intensive Care Medicine 8
Supportive Care
- Never leave the septic patient alone; ensure continuous observation, according to the American College of Critical Care Medicine 6
- Perform clinical examinations several times per day, as recommended by the European Society of Intensive Care Medicine 6
- Consider deep vein thrombosis prophylaxis, according to the American College of Chest Physicians 8
- Minimize continuous or intermittent sedation in mechanically ventilated patients, as suggested by the Surviving Sepsis Campaign 1
- Promote early mobilization, according to the European Society of Intensive Care Medicine 8
Special Considerations for Pediatric Patients
- Severe sepsis in children is more often characterized by cardiac failure and hypovolemia, as recommended by the Society of Critical Care Medicine 4
- Diagnosis is more difficult in children as hypotension develops later than in adults, according to the American Academy of Pediatrics 4
- Consider the use of colloid solutions for fluid resuscitation in children with severe Dengue shock syndrome, as suggested by the World Health Organization 3, 5
