Effects of Fluid Resuscitation With Colloids vs Crystalloids on Mortality in Critically III Patients Presenting With Hypovolemic Shock The CRISTAL Randomized Trial

摘要

RESULTS Within 28 days, there were 359 deaths (25.4%) in colloids group vs 390 deaths (27.0%) in crystalloids group (relative risk [RR], 0.96 [95% Cl, 0.88 to 1.04]; P = .26). Within 90 days, there were 434 deaths (30.7%) iffcolloids group vs 493 deaths (34.2%) in crystalloids group (RR, 0.92 [95% Cl, 0.86 to 0.99]; P = .03). Renal replacement therapy was used in 156 (11.0%) in colloids group vs 181 (12.5%) in crystalloids group (RR, 0.93 [95% Cl, 0.83 to 1.03]; P = .19). There were more days alive without mechanical ventilation in the colloids group vs the crystalloids group by 7 days (mean: 2.1 vs 1.8 days, respectively; mean difference, 0.30 [95% Cl, 0.09 to 0.48] days; P = .01) and by 28 days (mean: 14.6 vs 13.5 days; mean difference, 1.10 [95% Cl, 0.14 to 2.06] days; P = .01) and alive without vasopressor therapy by 7 days (mean: 5.0 vs 4.7 days; mean difference, 0.30 [95% Cl, -0.03 to 0.50] days; P = .04) and by 28 days (mean: 16.2 vs 15.2 days; mean difference, 1.04 [95% Cl, -0.04 to 2.10] days; P = .03).
