Retrospective Evaluation of the Prognosis and Prevalence of Hyperchloremia in Dogs and Cats

Corrected hyper[Cl^-] was a common electrolyte abnormality identified in dogs and cats, and it was associated with higher case-fatality rates than normal corrected [Cl^-]. Hospital-acquired corrected hyper[Cl^-] was less common but was associated with a higher case-fatality rate than prehospital corrected hyper[Cl^-] in dogs. Further investigation of corrected hyper[Cl^-] in association with its morbidity and mortality and the role of therapy to target normal [Cl^-] is warranted.
