┌─────────────────────────────────────────────────────────────────────────────┐
│ HOUR-1 BUNDLE │
├─────────────────────────────────────────────────────────────────────────────┤
│ □ Obtain BLOOD CULTURES x2 (aerobic + anaerobic) — ideally BEFORE │
│ antibiotics; do NOT delay antibiotics by > 45 min to get cultures │
│ │
│ □ Measure SERUM LACTATE (repeat if initial > 2 mmol/L) │
│ │
│ □ Administer BROAD-SPECTRUM ANTIBIOTICS: │
│ - Septic SHOCK → within 1 hr of recognition (STRONG) │
│ - Sepsis (no shock)→ within 1 hr (STRONG) │
│ - Low risk, no shock → defer; reassess at 3 hrs │
│ │
│ □ IV ACCESS: 2x large-bore peripheral IV or central venous catheter │
│ │
│ □ Start IV CRYSTALLOID RESUSCITATION: │
│ At least 30 mL/kg in first 3 hrs (conditional, low evidence) │
│ → Use BALANCED crystalloids (LR/PlasmaLyte) over 0.9% NaCl │
│ │
│ □ If MAP < 65 mmHg despite fluids → START VASOPRESSORS │
