According to the Surviving Sepsis Campaign guidelines (2021), what is the maximum time window for initiation of broad-spectrum antibiotics in a patient with septic shock?

Explanation

## Antibiotic Timing in Septic Shock **Key Point:** The Surviving Sepsis Campaign 2021 guidelines mandate initiation of broad-spectrum antibiotics within **1 hour** of recognition of septic shock. This is a critical time-sensitive intervention. **High-Yield:** Every hour delay in antibiotic administration in septic shock is associated with a 7–8% increase in mortality. This makes the 1-hour window a non-negotiable quality metric in sepsis bundles. **Clinical Pearl:** The 1-hour bundle for septic shock includes: 1. Measure lactate level 2. Obtain blood cultures before antibiotics 3. Administer broad-spectrum antibiotics 4. Administer 30 mL/kg crystalloid for hypotension or lactate ≥4 mmol/L 5. Apply vasopressors if hypotension does not respond to fluid resuscitation **Mnemonic:** **1-HOUR SEPTIC SHOCK** = 1-hour antibiotic window is the gold standard (not 3 or 6 hours, which were older recommendations).
