Is 30 mL/kg always the right fluid amount in sepsis?

The 30 mL/kg guideline provides a standardized initial approach. After the initial bolus, fluid responsiveness should guide further resuscitation. Studies like CLASSIC and SMART suggest that excessive fluids after initial resuscitation are harmful, and many patients require less than 30 mL/kg total.

What fluid is preferred for sepsis resuscitation?

Balanced crystalloids (Lactated Ringer's, PlasmaLyte) are preferred over normal saline per the SMART and SALT-ED trials, which showed lower rates of AKI and MAKE-30 events with balanced crystalloids. Albumin may be considered as an adjunct in patients receiving large fluid volumes.

Sepsis Fluid Resuscitation Target Calculator

Calculates initial fluid resuscitation volume for sepsis-induced tissue hypoperfusion. Recommendation: 30 mL/kg IV crystalloid (normal saline or lactated Ringer's) within 3 hours of sepsis recognition. After initial bolus, reassess with dynamic measures (pulse pressure variation, passive leg raise, point-of-care echo) to guide further fluid administration and avoid fluid overload.
