How do you manage sepsis in a critical care setting?

Management of Sepsis in Critical Care Settings

The management of sepsis in critical care requires immediate implementation of a bundle of interventions including fluid resuscitation with 30 mL/kg of crystalloids within the first 3 hours, administration of broad-spectrum antibiotics within 1 hour of recognition, source control measures, and hemodynamic support targeting a MAP of 65 mmHg with norepinephrine as the first-line vasopressor. 1

Initial Resuscitation and Recognition

Fluid Management

• Administer up to 40-60 mL/kg (10-20 mL/kg per bolus) of crystalloids in the first hour, titrated to clinical markers of cardiac output 2
• Use balanced/buffered crystalloids rather than 0.9% saline 2
• Avoid starches for resuscitation (strong recommendation) 2
• Monitor for signs of fluid overload (pulmonary edema, worsening hepatomegaly) 2
• Reassess frequently using dynamic variables to predict fluid responsiveness 1

Hemodynamic Support

• Target MAP ≥65 mmHg using vasopressors if fluid-refractory hypotension occurs 1
• Use norepinephrine as first-line vasopressor 1
• Consider epinephrine or dopamine for inadequate tissue perfusion despite fluid resuscitation 2
• Add vasopressin as needed for refractory shock 1
• Consider hydrocortisone or prednisolone for patients requiring catecholamines 2

Infection Management

Antimicrobial Therapy

• Critical timing: Administer antimicrobials within 1 hour of recognizing septic shock and within 3 hours for sepsis without shock 1
• Collect at least two sets of blood cultures before starting antibiotics 1
• Use empiric multi-drug therapy when septic shock is present/suspected 2
• Optimize antimicrobial dosing based on pharmacokinetic/pharmacodynamic principles 2
• Perform daily assessment for de-escalation of antimicrobial therapy 2
• Determine duration based on infection site, microbial etiology, treatment response, and source control 2

Source Control

• Implement emergent source control as soon as possible 2
• Remove infected intravascular access devices after establishing alternative access 2
• Perform thorough clinical investigation for infectious source identification 2
• Obtain fluid/tissue sampling for microbiological work-up 2

Monitoring and Reassessment

• Monitor:

  • Mean arterial pressure (target ≥65 mmHg)
  • Mental status
  • Capillary refill time
  • Urine output
  • Serum lactate levels (repeat within 6 hours if initially elevated)
  • Oxygen saturation (target >90%)

• Use frequent reassessment to guide ongoing management 1

• Consider advanced monitoring in hemodynamically unstable patients 2

Supportive Care

Respiratory Support

• Administer oxygen to achieve saturation >90% 2
• Position patient semi-recumbent and/or lateral 2
• Consider non-invasive ventilation for increased work of breathing or hypoxemia despite oxygen therapy 2
• If intubation needed, use lung-protective ventilation strategies 2

Nutrition and Additional Care

• Provide early enteral feeding rather than complete fasting 1
• Resume oral food intake after resuscitation and regaining consciousness 2
• Implement deep vein thrombosis prophylaxis (pharmacological or mechanical) 2
• Avoid hypoglycemia 2
• Use opioids and sedatives carefully 2
• Implement early mobilization 2
• Actively wean invasive support when appropriate 2

Special Considerations

• Adjust approach based on resource availability (resource-limited vs. resource-rich settings) 2
• Consider specific management approaches for special populations (children, pregnant women, immunocompromised patients) 2
• For pediatric patients, follow specific guidelines for fluid resuscitation and antimicrobial therapy 2

Common Pitfalls to Avoid

• Delaying antimicrobial therapy beyond 1 hour in septic shock
• Inadequate fluid resuscitation or excessive fluid administration without proper monitoring
• Failure to identify and control the source of infection
• Neglecting daily reassessment for de-escalation of antimicrobial therapy
• Overlooking non-infectious causes of SIRS that may mimic sepsis
• Inappropriate vasopressor use without adequate fluid resuscitation

By implementing this structured approach to sepsis management in critical care settings, clinicians can significantly improve patient outcomes by reducing morbidity and mortality through timely intervention and appropriate supportive care.
