Effects of Hydroxyethyl Starch 130/0.4 on Serum Creatinine Concentration and Development of Acute Kidney Injury in Nonazotemic Cats.J Vet Intern Med 2017; 31(6):1749-1756JV
Hydroxyethyl-starch (HES) solutions might have renal adverse effects in humans and dogs.
To determine if administration of 6% HES-130/0.4 is associated with an increase in serum creatinine concentration and development of acute kidney injury (AKI) in nonazotemic cats.
A total of 62 critically ill cats; 26 HES exposed and 36 unexposed.
Retrospective cohort study (2012-2015). Serum creatinine concentrations were recorded and changes in serum creatinine concentrations before exposure (baseline) and 2-10 and 11-90 days, respectively, were determined. Development of AKI was defined as a > 150% increase or >26 μmol/L increase in serum creatinine concentration from baseline. Risk factors, such as HES administration, cumulative volume of HES (mL/kg) and number of days of HES administration leading to development of AKI, and change in serum creatinine were analyzed.
Cats in the HES cohort received a mean volume of 98.5 ± 76.2 mL/kg (range, 8-278 mL/kg) HES over a median of 4 (range, 1-11) days, resulting in a median dose of 20.1 (range, 8-40.5) mL/kg per day. Short-term %change in serum creatinine concentration (P = 0.40) and development of AKI (P = 0.32) were not significantly different between cohorts. Multivariable logistic regression did not identify HES dose in mL/kg (P = 0.33) and number of days of HES application (P = 0.49) as a risk factor for development of AKI.
CONCLUSION AND CLINICAL IMPORTANCE
Hydroxyethyl-starch administration to critically ill nonazotemic cats seems to be safe. A larger prospective study is required to determine the effect of HES administration at higher dosages and for prolonged time periods.
