Hour-1 Bundle in sepsis

For critically ill patients with sepsis or septic shock, time is of the essence.

Although the starting time for the Hour-1 bundle is recognition of sepsis, both sepsis and septic shock should be viewed as medical emergencies requiring rapid diagnosis and immediate intervention.

The Hour-1 bundle encourages clinicians to act as quickly as possible to obtain blood cultures, administer broad spectrum antibiotics, start appropriate fluid resuscitation, measure lactate, and begin vasopressors if clinically indicated.

Ideally these interventions would all begin in the first hour from sepsis recognition but may not necessarily be completed in the first hour. Minimizing the time to treatment acknowledges the urgency that exists for patients with sepsis and septic shock. The elements of Hour-1 Bundle of care are:

·         Measure lactate level; remeasure lactate if initial lactate is elevated (> 2 mmol/L).

·         Obtain blood cultures before administering antibiotics.

·         Administer broad-spectrum antibiotics.

·         Begin rapid administration of 30mL/kg crystalloid for hypotension or lactate level ≥ 4 mmol/L.

·         Apply vasopressors if hypotensive during or after fluid resuscitation to maintain MAP ≥ 65 mm Hg.
