There is no mortality difference between restrictive fluid strategy and liberal fluid strategy in septic patients


  • early study in 2013 found increased mortality with patients having high positive fluid balance. 1

Meta analysis

Meta analysis in 2020 showing liberal fluid therapy has worsening outcome.2

Classic trial

Published 6/2022.

Restrictive strategy (no fluid unless hypoperfusion) compared to liberal strategy (no upper limit of fluids) did not show improved mortality benefit.

Patients both received median 3 L prior to randomization. Total difference in fluid by day 5 was similar in both group (8.8L vs 10.8L).3

Clovers trial

Published Clovers trial 2/2023

In patients with sepsis induced hypotension, a restrictive fluid strategy (total up to 2L including pre-randomization) does not improve mortality, ventilator free days, days out of ICU, new intubation, new ARDS compared to liberal fluid strategy (immediate 2L at randomization after 1-3L pre-randomization and then 500 cc bolus PRN, with rescue vasopressor to be given after 5L total).

Patients with restrictive fluid strategy had higher ICU admission rates.4
