Do hypooncotic fluids for shock increase the risk of late-onset acute respiratory distress syndrome?
OBJECTIVE: In patients with shock, late-onset acute respiratory distress syndrome (ARDS) carries poor prognosis. Hypooncotic fluids may improve kidney function preservation, whereas hyperoncotic fluids may in theory decrease the risk of late-onset ARDS. Our objective was to determine whether predominant or exclusive use of crystalloids and/or hypooncotic colloids for shock resuscitation influenced the risk of late-onset ARDS. PARTICIPANT AND SETTINGS: International prospective cohort of consecutive adults who were free of ARDS on admission and who received fluid resuscitation for shock in 115 intensive care units (ICUs) during a 4-week period. MEASUREMENTS AND RESULTS: Severity scores, hemodynamic status, indication for fluids, risk factors for ARDS, plasma expander use, transfusions, and late-onset ARDS were recorded prospectively. Logistic regression models were tested to determine whether predominant or exclusive use of hypooncotic fluids was associated with higher incidence of late
