Sepsis and septic shock
Bottom line
- Sepsis is a medical emergency. Start treatment and resuscitation immediately. No single test rules sepsis in or out.1,2
- Antibiotics within 1 hour for possible, probable or definite septic shock, and for probable or definite sepsis without shock. For possible sepsis without shock, investigate quickly and give antibiotics within 3 hours if the concern persists.1,2
- Antibiotic delay costs lives; fluid speed less clearly so. In 49,331 New York patients, each hour to antibiotics raised the odds of in-hospital death (OR 1.04 per hour). Time to complete the fluid bolus did not.3
- Give at least 30 mL/kg of crystalloid within 3 hours for hypoperfusion or septic shock. Prefer balanced crystalloids over saline.1,2
- Target a MAP of 65, or 60–65 if 65 or older. Norepinephrine is first-line. Start it through a peripheral IV rather than waiting for a central line.1,2
Recognize
- Screen with NEWS, NEWS2, MEWS or SIRS, not qSOFA. This is a strong recommendation (moderate certainty).1,2
- Diagnosis is clinical. Don't rule sepsis in or out on one biomarker or test.1,2
- Measure lactate (conditional, low certainty). Serial lactate can guide resuscitation, with capillary refill time as an adjunct.1,2
- Get blood cultures as soon as possible, ideally before antibiotics (strong, low certainty).1,2
First hour
- Decide how likely infection is, and whether there is shock. That decision sets the antibiotic clock (table below).1,2
- Draw blood cultures and lactate, without delaying antibiotics.1,2
- Give antibiotics within 1 hour for shock or probable sepsis.1,2
- Start crystalloid: at least 30 mL/kg within 3 hours for hypoperfusion or shock. Base the dosing weight on BMI.1,2
- If hypotension persists after the first bolus, start norepinephrine, peripherally if needed. In unstable shock, vasopressors can run alongside fluids.1,2
- Look for a source that needs control, and aim to control it within 6 hours.1,2
| Presentation | Antimicrobials | Strength |
|---|---|---|
| Possible, probable or definite septic shock | Immediately, ideally within 1 hour | Strong, very low certainty |
| Probable or definite sepsis, no shock | Immediately, ideally within 1 hour | Strong, very low certainty |
| Possible sepsis, no shock | Rapid, time-limited workup. Give within 3 hours if concern persists | Conditional, very low certainty |
| Low likelihood of infection, no shock | Defer and monitor closely | Conditional, very low certainty |
From the 2026 Surviving Sepsis Campaign adult guidelines.1,2 Use clinical evaluation, not procalcitonin, to decide whether to start antibiotics.2
Fluids
- Crystalloids first (strong, moderate certainty). Prefer balanced crystalloids over 0.9% saline (conditional, moderate). Saline is suggested instead in traumatic brain injury.1,2
- Crystalloid alone over adding albumin (conditional, moderate). Albumin may suit very large volumes or cirrhosis; avoid it in traumatic brain injury.1,2
- No starches (strong, high certainty) and no gelatin (conditional).1,2
- Beyond the first 30 mL/kg, use dynamic measures such as a passive leg raise or fluid challenge over static ones.1,2
What the trials show
- CLOVERS (n = 1,563, sepsis-induced hypotension after initial fluid): a restrictive, vasopressor-early strategy used about 2.1 L less fluid in 24 hours. Mortality by day 90 was 14.0% vs 14.9%, not significantly different.4,10
- SMART (n = 15,802 critically ill adults): balanced crystalloids lowered the composite of death, new dialysis or persistent kidney dysfunction (14.3% vs 15.4%).5
Vasopressors
| Step | Recommendation | Strength |
|---|---|---|
| Target | MAP 65 mm Hg (practical range about ±5) | Strong, moderate |
| Age ≥ 65 | MAP 60–65 mm Hg | Conditional, low |
| First line | Norepinephrine | Strong |
| Access | Start peripherally rather than waiting for a central line | Conditional, very low |
| Rising norepinephrine dose | Add vasopressin | Conditional, moderate |
| MAP still low on both | Add epinephrine | Conditional, very low |
| Cardiac dysfunction | Norepinephrine or epinephrine first; add an inotrope for persistent hypoperfusion | Conditional, very low |
| Avoid | Dopamine, terlipressin, beta-blockers in septic shock | Strong to conditional |
Support for the lower target in older adults: in the 65 trial (n = 2,463, age ≥ 65), permissive hypotension cut vasopressor exposure. Mortality at 90 days was 41.0% vs 43.8%, not significant.8 The guideline's new recommendation is MAP 60–65 for this group.2
Corticosteroids
The guideline suggests IV corticosteroids in septic shock (conditional, low certainty).1,2
Antimicrobials and source control
- Cover multidrug-resistant organisms only if the patient is at high risk for them. Skip routine empiric antifungal and anaerobic coverage unless risk factors are present.1,2
- Give beta-lactams as a prolonged infusion after a loading dose (strong, moderate certainty).1,2
- Evaluate quickly for a source needing emergent control (good practice), and control it early, ideally within 6 hours.1,2
- De-escalate once a pathogen and its susceptibilities are known.1,2
Other ED decisions
- Oxygen: for hypoxemic respiratory failure, high-flow nasal cannula over conventional oxygen and as first-line over noninvasive ventilation (conditional).1,2
- Bicarbonate: not for improving hemodynamics in lactic acidemia. Consider it when pH ≤ 7.2 with stage 2–3 acute kidney injury (conditional, very low).1,2
- Glucose: start insulin at ≥ 180 mg/dL (strong).1,2
- Not recommended: IV vitamin C, IV immunoglobulin, routine blood purification.1,2
- Transfusion: restrictive thresholds over liberal (strong).1,2
- Prehospital: screening en route and, where in-hospital evaluation will take over 60 minutes, antibiotics for septic shock once a structured screening process exists.1,2
Where experts disagree
A group of emergency and critical care physicians published a rebuttal to the 2026 guidelines. They argue the recommendations have drifted toward mandated bundles and metric-driven care, and they urge clinicians to individualize resuscitation rather than follow protocols by rote.9 Most 2026 recommendations rest on low or very low certainty evidence.2
Pitfalls
- Using qSOFA as the screening tool. The guideline recommends against it as a single screen.1,2
- Waiting for a central line before starting norepinephrine.1,2
- Holding antibiotics while cultures are drawn. Cultures should come first only if they don't delay treatment.1,2
- Pushing fluid past the first 30 mL/kg without checking whether the patient is still fluid-responsive.1,2,4
- Chasing a MAP above 65 in older adults by default.2,8
How strong is the evidence?
The 2026 update has 129 statements, 46 of them new, and covers evidence through June 2025. Most recommendations are conditional and rest on low or very low certainty evidence.2 The guideline's full text was not openly accessible, so the recommendations here come from the official SCCM summary and are cited to both.1,2 For a podcast discussion of CLOVERS, see REBEL EM.10
