Introduction: The treatment of different electrolyte imbalances is an essential component of life-supporting care in an intensive care unit, especially for young patients. Pediatric intensive care units frequently experience electrolyte imbalances. Aims: To evaluate the electrolyte imbalance trend in pediatric critical care. to determine the many causes of electrolyte imbalances. To evaluate how electrolyte imbalances affect mortality, length of PICU admission, and after effects. Materials & Methods: This was a prospective, observational cohort study conducted in the Department of Pediatric Medicine at Calcutta National Medical College and Hospital, a tertiary care center. The study was carried, from 2021 to 2022, and included a total of 150 pediatric patients. Result: In 38 patients (25%) in our investigation, dyselectrolytemia was most frequently seen as mixed abnormalities. 36 patients (24%), 32 patients (21%), and 27 patients (18%) had hyponatremia, metabolic acidosis, and hypokalemia, respectively. Hyperkalemia (12 patients, 8%), hypocalcemia (9 patients, 6%), hypernatremia (6 patients, 4%), and hypercalcemia (5 patients, 3%), were less common anomalies. (p< 0.00001) It was statistically significant. Conclusion: We concluded that the bulk of the 150 pediatric patients in our study who were admitted to the PICU were male newborns between the ages of one month and one year. Central nervous system infections were the most common underlying cause, and mixed electrolyte imbalances were the most commonly found.
