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 verify the prevalence rate, associated factors, and the impact of hyponatremia on in-patients length of stay (LOS) and in-hospital mortality. METHODS: A descriptive observational cross-sectional study was carried out in a sample of 80 individuals. 39 (48.7%) were females and 41 (51.3%) were males. Demographics, clinical and laboratory data were colected. Patient’s Comorbidities and their medications in use were also collected. RESULTS: During the study period, 44 (55%) patients had hyponatremia. Average length of stay of the patients admitted with community-acquired hyponatremia (CAH) was 29.5 days. It was a higher average when compared to the hospitalization time of patients admitted with eunatremia, who had an average length of stay of 20.8 days. None of the patients of the present research died. Some type of treatment was proposed for 22 (50%) of hyponatremic patients. 30 (37.5%) patients were in hyponatremia on hospital discharge. 20 (80%) of the 25 patients who took diuretics had hyponatremia. 12 (70.5%) of the 17 patients who took antidepressants had hyponatremia. Five (71.4%) of the seven patients with a previous diagnosis of Congestive Heart Failure (CHF) were hyponatremic patients. Four (80%) of the five patients with a previous diagnosis of hepatic cirrhosis were hyponatremic. Four (80%) of the five patients with a previous diagnosis of Chronic Kidney Disease (CKD) were hyponatremic. CONCLUSION: Hyponatremia is a common electrolyte disorder in patients hospitalized at HU-UFS. Patients diagnosed with CHF, CKD and cirrhosis, and patients who have used diuretics and antidepressants commonly presented this disorder. Finally, patients with hyponatremia presented longer hospital length of stay when compared to eunatremic patients.
