The Bottom Line: The Surviving Sepsis Guideline states 30cc/kg within first 3 hours for sepsis or shock, as defined by new Sepsis definitions (Singer et al, 2016).

Summary: While some of the recent data on timing of IVFs (Seymour et al, 2017) suggest that completion of the initial IVF bolus within the first 3 hours is not associated with mortality improvement compared to completion of the initial IVF bolus beyond 3 hours, other data (Leisman et al, 2016) suggest that the earlier initiation of IVFs (within the first 30 minutes) is associated with improved mortality and reduced hospital length of stay.
The current guidelines, as listed in DynaMed Plus, call for fluids within 3 hours.
