Abstract

Objective: To determine the association of dysnatremia in the first postnatal week and risk of acute kidney injury (AKI) and mortality. Study design: A secondary analysis of 1979 neonates in the AWAKEN cohort evaluated the association of dysnatremia with (1) AKI in the first postnatal week and (2) mortality, utilizing time-varying Cox proportional hazard models. Result: Dysnatremia developed in 50.2% of the cohort and was not associated with AKI. Mortality was associated with hyponatremia (HR 2.15, 95% CI 1.07–4.31), hypernatremia (HR 4.23, 95% CI 2.07–8.65), and combined hypo/hypernatremia (HR 6.39, 95% CI 2.01–14.01). In stratified models by AKI-status, hypernatremia and hypo/hypernatremia increased risk of mortality in neonates without AKI. Conclusion: Dysnatremia within the first postnatal week was associated with increased risk of mortality. Hypernatremia and combined hypo/hypernatremia remained significantly associated with mortality in neonates without AKI. This may reflect fluid strategies kidney injury independent of creatinine and urine-output defined AKI, and/or systemic inflammation.
