Avaliação do nível sérico de sódio em pacientes hospitalizados na enfermaria da clínica médica do Hospital Universitário da Universidade Federal de Sergipe

Abstract

Objective:To evaluate the frequency, impact on length of hospital stay, clinical progression, associated factors and deaths of this clinical condition in our setting. Methods:A descriptive observational cross-sectional study was conducted in a sample of 80 individuals, consisting of 39 (48.7%) female patients and 41 (51.3%) male patients. Demographic, clinical, laboratory data, comorbidities, medications in use and length of hospital stay were collected. Results:During the study period, 44 (55%) patients presentedhyponatremia. The length of hospital stay of patients admitted with hyponatremia (29.5 ± 29.7 days) was longer when compared to the length of hospital stay of patients admitted with eunatremia, who had a mean hospital stay of 20.8 days. No patient in the study died. Some type of treatment was proposed for 22 (50%) of the hyponatremic patients. At hospital discharge, 30 (37.5%) patients were hyponatremic. 20 (80%) of the 25 patients using diuretics had hyponatremia. 12 (70.5%) of the 17 patients using antidepressants had hyponatremia. Five (71.4%) of the seven patients diagnosed with Congestive Heart Failure were hyponatremic patients. Four (80%) of the five patients diagnosed with liver cirrhosis were hyponatremic. Four (80%) of the five patients diagnosed with Chronic Kidney Disease were hyponatremic. Conclusion:Hyponatremia is a common electrolyte disorder in patients hospitalized at HU-UFS, resulting in longer hospital stays and hospital readmissions. It is inferred that the use of diuretics, antidepressants and previous pathologies presented by patients such as Congestive Heart Failure, Chronic Kidney Disease and Cirrhosis contribute to the onset of hyponatremia.
