BACKGROUNDTo study the incidence, aetiology and length of ICU stay in children admitted to Paediatric Intensive Care Unit with electrolyte disturbances.
MATERIALS AND METHODSDescriptive prospective study in children aged 1 month to 12 years.
RESULTSIncidence of hyponatraemia (< 135 mEq/L) was 16.8%, hypernatraemia (> 145 mEq/L) 4%, hypokalaemia (< 3.5 mEq/L) 11.9% and hyperkalaemia (> 5.5 mEq/L) 2% respectively; 01 month -4 years age (41.2%) group of our study population emerged as a susceptible age group to electrolyte disturbances with mean age of 4.36 ± 4.10 yrs. Hyponatraemia occurred in 64.7% of boys, hypernatraemia occurred in 75% boys, hypokalaemia and hyperkalaemia in 50% boys. Spectrum of illness in hyponatraemia includes CNS disorders (52.9%), GI disorders (17.6%) and sepsis (11.8%). In hypernatraemia all four children were diagnosed to have CNS disorders. In hypokalaemia group CNS disorders, GI disorders, sepsis and renal disorders were responsible for 58.3%, 16.7%, 8.3% and 8.3% respectively. In hyperkalaemia group, CNS and GI disorders were responsible for 50% each. Mean Length of Stay (LOS) in hyponatraemia was 8.18 ± 7.65 days, hypernatraemia 10.50 ± 4.65 days, hypokalaemia 9.0 ± 8.56 days and hyperkalaemia 9.50 ± 7.78 days. Mortality was 1.9 times higher in children with hyponatraemia and 1.2 times higher in children with hypokalaemia compared to normal serum levels.
CONCLUSIONDisturbances in the serum sodium and potassium levels during the ICU stay predicted an increased length of hospital stay. Early detection through regular monitoring and early correction may help in improving the outcome.
