Sepsis Resuscitation: What to Do in the First Hour

Sepsis is one of the most time-sensitive emergencies in the ED. Every hour of delay in treatment increases mortality. For rookies, the first 60 minutes are critical: this is where you either turn the tide — or watch the patient spiral.


What Is Sepsis?

  • A life-threatening organ dysfunction caused by a dysregulated response to infection.
  • In the ED, you don’t need perfect definitions — you need to recognize it fast.

Think: infection + abnormal vitals + organ dysfunction.


Step 1: Recognition (Minutes 0–5)

  • Suspect sepsis in any patient with:
    • Fever or hypothermia.
    • Tachycardia, tachypnea.
    • Hypotension or narrow pulse pressure.
    • Altered mental status.
    • Hypoxia, oliguria, mottled skin.
  • Use bedside tools (qSOFA, pediatric sepsis criteria) but don’t delay for scoring.

Rookie pearl: If the patient “just looks sick,” trust your gut and act.


Step 2: Immediate Actions (Minutes 5–15)

  1. IV/IO access ×2 large-bore (or central line if necessary).
  2. Labs & cultures: CBC, electrolytes, lactate, blood cultures ×2, urine, others as needed.
  3. Monitor: cardiac, SpO₂, BP, urine output.
  4. Oxygen: give supplemental O₂ if hypoxic.
  5. Start fluids:
    • Adults: 30 mL/kg isotonic crystalloids (NS or LR).
    • Children: 20 mL/kg bolus, reassess, repeat as needed.

Step 3: Antibiotics (Minutes 15–30)

  • Give broad-spectrum antibiotics within 1 hour of recognition.
  • Choice depends on source:
    • Pneumonia: ceftriaxone + azithromycin or cefepime + vancomycin if HAP.
    • Intra-abdominal: piperacillin-tazobactam or meropenem.
    • Sepsis unknown source: broad (e.g., vancomycin + cefepime).
  • Adjust when cultures return.

Step 4: Reassessment (Minutes 30–45)

  • Repeat vitals, exam, cap refill.
  • Lactate trend: if elevated, repeat in 2–4 hrs.
  • Look for signs of fluid overload (lungs, JVP, CXR).

Step 5: Vasopressors (Minutes 45–60)

  • If hypotension persists after fluids → start pressors.
  • First-line: norepinephrine (adults), epinephrine (children).
  • Can be started peripherally while central line arranged.
  • Goal:
    • Adults: MAP ≥65 mmHg.
    • Children: age-appropriate BP or good perfusion.

Adjuncts

  • Source control (drain abscess, remove infected line).
  • Correct hypoglycemia or electrolyte abnormalities.
  • Stress-dose steroids if adrenal crisis or refractory shock.

Common Rookie Mistakes

  • Waiting for hypotension before treating — sepsis can exist with normal BP.
  • Delaying antibiotics while waiting for cultures.
  • Giving maintenance fluids instead of aggressive resuscitation.
  • Forgetting to reassess after fluid bolus.
  • Not starting pressors early enough.

Rookie Pearls

  • The first hour is golden.
  • Cultures before antibiotics — but never delay antibiotics if unstable.
  • 30 mL/kg in adults, 20 mL/kg in kids — reassess frequently.
  • Pressors peripherally are safe — don’t wait for central line.
  • Reassess, repeat lactate, escalate early.

Take-Home Message

For rookies:

  • Sepsis resuscitation is about speed and structure.
  • In the first hour: fluids, cultures, antibiotics, reassessment, pressors if needed.
  • Admit all to ICU or monitored unit.

Remember: In sepsis, every minute counts — don’t lose the first hour.
