Objective To determine the incidence of in‐hospital adverse outcomes including acute kidney injury (AKI) and death in a population of dogs admitted to the intensive care unit (ICU) receiving 10% hydroxyethyl starch (HES) [250/0.5/5:1] compared with the general ICU population, while controlling for illness severity. Design Cohort study conducted between January 2007 and March 2010. Setting Veterinary teaching hospital. Animals Consecutive sample of dogs receiving HES ( n = 180) were compared with a randomly selected sample of dogs ( n = 242) admitted to the ICU over the same period. Interventions None Measurements and Main Results AKI was defined as an at least 2‐fold increase in baseline creatinine concentration or new onset of oliguria/anuria persisting for ≥12 hours. The primary outcome was a composite of in‐hospital death or AKI. Unadjusted and adjusted analysis controlling for illness severity using the acute patient physiologic and laboratory evaluation (APPLE fast ) score and other confounders was performed. HES was administered either as incremental boluses (median dose 8.2 mL/kg/day, interquartile range [IQR] 5.0–11.3 mL/kg/day) or as a continuous rate infusion (CRI; median dose 26mL/kg/day, IQR 24.0–48 mL/kg/day). In unadjusted analysis, HES administration was associated with increased risk of mortality (odds ratio [OR] = 2.33, 95% confidence interval [CI] = 1.51–3.58, P < 0.001) or AKI (OR = 3.87, 95% CI = 1.21–12.37, P = 0.02). In an adjusted analysis after controlling for illness severity, admission type, and concurrent administration of blood products, HES administration remained an independent risk factor for the composite adverse outcome (OR = 1.98, 95% CI = 1.22–3.22, P = 0.005), with a number needed to harm (NNH) = 6 (95% CI = 4–23). Conclusions HES therapy is associated with increased risk of an adverse outcome including death or AKI in dogs. A randomized controlled trial investigating the safety of HES therapy in canine patients is warranted.
