What are the current 2026 recommendations for early recognition, fluid resuscitation, antimicrobial therapy, vasopressor use, source control, and post‑acute care of sepsis and septic shock?

Sepsis Update 2026

Early Recognition and Risk Stratification

Use the NEWS2 scoring system to stratify risk and determine the urgency of antibiotic administration in suspected sepsis. 1

• Calculate NEWS2 scores based on six physiological parameters: respiratory rate, oxygen saturation, supplemental oxygen requirement, systolic blood pressure, pulse, consciousness level (CVPU), and temperature 1
• Risk stratification determines antibiotic timing:
  • NEWS2 score 0 = very low risk 1
  • NEWS2 score 1-4 = low risk 1
  • NEWS2 score 5-6 = moderate risk 1
  • NEWS2 score ≥7 = high risk 1
• A score of 3 in any single parameter may indicate increased sepsis risk and warrants immediate attention 1
• Implement routine screening protocols for potentially infected seriously ill patients to enable earlier treatment 1

Antimicrobial Therapy

Administer IV antimicrobials within one hour of recognizing sepsis or septic shock. 1

Initial Empiric Therapy

• Start broad-spectrum antimicrobials covering all likely pathogens (bacterial, fungal, or viral) that penetrate adequately into the presumed infection source 1
• Obtain blood cultures before antibiotics (at least two sets: one percutaneous, one through vascular access if present >48 hours) if this causes no substantial delay (>45 minutes) 1

Combination Therapy Considerations

• Use combination therapy (two different antimicrobial classes) for:
  • Initial management of septic shock (weak recommendation) 1
  • Multidrug-resistant pathogens (Acinetobacter, Pseudomonas species) 1
  • Pseudomonas aeruginosa bacteremia with respiratory failure/septic shock: extended-spectrum β-lactam plus aminoglycoside or fluoroquinolone 1
  • Bacteremic Streptococcus pneumoniae septic shock: β-lactam plus macrolide 1
• Do NOT use routine combination therapy for:
  • Neutropenic sepsis/bacteremia (strong recommendation against) 1
  • Most other serious infections without shock 1

De-escalation and Duration

• Reassess antimicrobial regimen daily for potential de-escalation 1
• Discontinue combination therapy within 3-5 days once susceptibilities are known 1
• Typical duration: 7-10 days; longer courses for slow clinical response, undrainable foci, S. aureus bacteremia, fungal/viral infections, or immunodeficiency 1
• Consider procalcitonin or similar biomarkers to guide discontinuation in patients without confirmed infection 1
• Optimize dosing based on pharmacokinetic/pharmacodynamic principles 1

Fluid Resuscitation

Administer at least 30 mL/kg of IV crystalloid fluid within the first 3 hours for sepsis-induced hypoperfusion. 1

Fluid Selection

• Use crystalloids as first-line fluid for initial resuscitation and volume replacement 1
• Balanced crystalloids or saline are both acceptable options (weak recommendation for balanced over saline in 2021 updates) 1, 2
• Add albumin to crystalloids when patients require substantial amounts of crystalloids 1
• Avoid hydroxyethyl starches (strong recommendation against) 1
• Use crystalloids over gelatins 1

Fluid Administration Strategy

• Continue fluid administration as long as hemodynamic factors improve based on frequent reassessment 1
• Use dynamic variables over static variables to predict fluid responsiveness when available 1
• Reassess hemodynamic status frequently using clinical examination, vital signs, urine output, and available monitoring 1

Vasopressor Therapy

Initiate norepinephrine as the first-choice vasopressor targeting a mean arterial pressure (MAP) of 65 mmHg. 1

Vasopressor Selection Algorithm

• First-line: Norepinephrine (strong recommendation) 1
• Second-line options when additional agent needed:
  • Add vasopressin (0.03 units/minute) to raise MAP or decrease norepinephrine dose 1
  • Add epinephrine if additional agent needed 1
• Dopamine only for highly selected patients (low tachyarrhythmia risk, bradycardia) 1
• Phenylephrine NOT recommended except when norepinephrine causes serious arrhythmias, cardiac output is high with persistent hypotension, or as salvage therapy 1

Vasopressor Administration

• Consider peripheral initiation over delaying for central access (new weak recommendation in 2021) 2
• Place arterial catheter as soon as practical for all patients requiring vasopressors 1
• Do NOT use low-dose dopamine for renal protection 1
• Reserve vasopressin >0.03-0.04 units/minute for salvage therapy only 1

Inotropic Support

• Consider dobutamine infusion (up to 20 μg/kg/min) for myocardial dysfunction with elevated filling pressures and low cardiac output 1

Source Control

Identify and implement source control as rapidly as possible, ideally within the first 6-12 hours. 1

• Rapidly identify or exclude anatomic diagnosis requiring emergent source control 1
• Use the least physiologically invasive intervention (e.g., percutaneous drainage over surgical) 1
• Remove intravascular access devices promptly if they are a possible source, after establishing alternative access 1
• Delay definitive intervention when adequate demarcation of viable/nonviable tissue has not occurred 1

Adjunctive Therapies

Corticosteroids

• Use IV corticosteroids for septic shock when there is ongoing vasopressor requirement (new weak recommendation in 2021) 2

Lactate-Guided Resuscitation

• Target lactate normalization in patients with elevated lactate levels as a marker of tissue hypoperfusion 1

Post-Acute Care and Long-Term Outcomes

Screen all sepsis survivors for physical, cognitive, emotional, economic, and social support needs. 1, 2

Discharge Planning

• Use shared decision-making in post-ICU and hospital discharge planning 1, 2
• Reconcile medications at both ICU and hospital discharge 1, 2
• Provide written and verbal information about sepsis and its sequelae in discharge summary 1, 2
• Arrange assessment and follow-up for physical, cognitive, and emotional problems after discharge 1, 2
• Make referrals for follow-up where available 1, 2

Goals of Care

• Discuss goals of care and prognosis with patients and families 1
• Incorporate goals into treatment planning using palliative care principles where appropriate 1
• Address goals of care within 72 hours of ICU admission 1

Key Practice Points

• The 2024 NICE guidance represents the most recent update, emphasizing NEWS2-based risk stratification for antibiotic timing 1
• The one-hour antibiotic bundle remains a strong recommendation, with additional nuance when diagnosis is uncertain 1, 2
• The 30 mL/kg fluid bolus recommendation was downgraded from strong to weak in 2021, emphasizing individualized reassessment 2
• Post-sepsis care and survivorship have gained prominence with 12 new recommendations in 2021 addressing long-term outcomes 2
• Precision medicine approaches using machine learning and biomarkers are emerging but not yet standard practice 3, 4
