Prevalence and Impact of Hyponatremia in Icu Patients: A Comprehensive Study

Objective: Hyponatremia is the most frequently reported electrolyte disorder in hospitalized patients worldwide and occasionally in outpatients. Hyponatremia term is used when serum sodium concentration is less than 135meq/l. Therefore, the present study aimed to evaluate hyponatremia patients in ICU admission and its associated comorbidities. Methods: The study was conducted after getting due approval from the Institutional Ethics Committee. It was a cross-sectional, descriptive study comprised of 99 participants from medical and surgical ICUs of a tertiary care hospital. Results: The frequency of hyponatremia on ICU admission was 41.41 % of all ICU admissions P<0.0001. Females comprised 29.2% of hyponatremic patients and 39.6% of the normal serum sodium group. The mean age of patients with hyponatremia was 34.12±21.71 years. Conclusion: From this study, we can conclude that the prevalence of hyponatremia in exceptionally high in ICU-admitted patients and is associated with comorbidities such as T2DM, HTN, and CKD, in line with previous studies. Large multicentric studies are recommended to bring out the association with different variables.
