The rapid and aggressive administration of these fluids may lead to adverse results, including acute renal failure and hydroelectrolytic disorders which are highly associated with fatal outcomes.  Objectives: To establish the association between hyperchloremia and mortality in patients admitted to the intensive care unit (ICU) of Hospital Universitario de San José between August 2013 and January 2017, in addition to their demographic characteristics, the incidence of chloride abnormalities, and its association to renal failure.  Methods: Analytic retrospective cohort study in the adult ICU at the Hospital Universitario de San José from August 1, 2013 to January 31, 2017.  Results: A total of 839 patients were evaluated, 210 exposed and 629 not exposed. The relative risk of death for those who developed hyperchloremia was 3.12 (95% confidence interval [CI] 2.16&#94;.49) (P &lt;0.001). The multivariate analysis generated an hazard ratio of 2.31 (95% CI 1.47-3.63) adjusted for age, sex, APACHE II at admission, sepsis, neurocritical state, and development of renal failure.  Conclusion: Hyperchloremia is a frequent event in patients in the ICU; it may act as an independent variable for mortality in critical patients.]]></p></abstract>

Objetivos: Establecer la asociación entre hipercloremia y mortalidad en los pacientes hospitalizados en cuidados intensivos del hospital Universitario de San José entre agosto de 2013 y enero de 2017, así como sus características demográficas, incidencia de anormalidades del cloro y su asociación con falla renal.  Métodos: Estudio analítico de cohortes retrospectiva, en la Unidad de Cuidados intensivos (UCI) adultos del Hospital Universitario de San José, en el período comprendido entre el 1 de agosto de 2013 y el 31 de enero de 2017.  Resultados: Fueron evaluados 839 pacientes, 210 expuestos y 629 no expuestos. El riesgo relativo para muerte en los que desarrollaron hipercloremia fue 3.12 (IC95% 2.16-4.49) (p &lt;0.001). En el análisis multivariado se obtuvo un HR de 2.31 (IC95% 1.473.63) ajustado por las variables de edad, sexo, APACHE II al ingreso, sepsis, estado neurocrítico y desarrollo de falla renal.  Conclusiones: La hipercloremia es un evento frecuente durante la atención de los pacientes en la unidad de cuidados intensivos; puede actuar como una variable independiente de mortalidad en los pacientes críticos.]]></p></abstract>
