ObjectiveTo evaluate the ability of admission base excess (ABE) to predict blood transfusion requirement and mortality in dogs following blunt trauma.DesignRetrospective study 2007-2009.SettingUniversity Veterinary Teaching Hospital.AnimalsFifty-two dogs admitted to the intensive care unit for treatment following blunt trauma.Measurements And Main ResultsAnimals requiring red blood cell transfusion (N = 8) had significantly lower ABE than those not requiring transfusion (N = 44; median base excess [BE] = -8.4 versus -4.7, P = .0034), while there was no difference in admission packed cell volume (PCV) or age. Animals that died or were euthanized due to progression of signs (N = 5) had lower median ABE than those that survived (N = 47; median BE = -7.3 versus -4.9, P = 0.018). Admission PCV and age were not significantly different between survivors and nonsurvivors. Receiver operator characteristic curve analysis showed an ABE cutoff of -6.6 was 88% sensitive and 73% specific for transfusion requirement (P < 0.001), and a cutoff of -7.3 was 81% sensitive and 80% specific for survival (P < 0.001). Multivariate logistic regression analysis demonstrated that ABE was a predictor of transfusion requirement that was independent of overall severity of injury as measured by the Animal Triage Trauma (ATT) score, but a similar analysis showed that only ATT was an independent predictor of survival.ConclusionsThe ABE in dogs with blunt trauma was a predictor of mortality and blood transfusion requirement within 24 hours.© Veterinary Emergency and Critical Care Society 2012.
