Warndorf MG, [49] | RC (n = 434) | NS (in 85% of cases) | Early FT: ≥ 1/3 of the total 72 h fluid volume administered in the first 24 h Late FT: < 1/3 administered in the first 24 h (2.403 ml/24 h) | / | Mortality, SIRS, OF, ICU, LOS | Less SIRS, ICU, OF associated with early FT |
De-Madaria E, [74] | RC (n = 247) | NS plus D5%/D10% | FT volume in first 24 h: Group A: < 3.1 L Group B: 3.1 – 4.1 L Group C: > 4.1 L | Ht < 44%, UO > 50 ml/h, low Cr, normal SBP | OF, PN, APFC, mortality | Group C had more RF and AKI rate |
