Abstract
Objectives: Neonatal mortality rate is one of the key indicator in the health status of a nation, and directly reflects prenatal, intra
partum, and neonatal care.
Aim of this study: To find out the association of electrolyte and acid base disorder in critically sick neonates at the time of admission
in NICU as predictor of their mortality.
Methods: This retrospective study was conducted in the department of Neonatology, Bangladesh Shishu Hospital and Institute
(BSH&I), Sher-E-Bangla Nagar, Dhaka, from January 2023 to June 2023. Total 115 neonates were included in this study having serum
electrolyte and arterial blood gas with other basic biochemical parameter analyzed at the time of admission.
Results: Blood pH, HCO3-, Base excess were lower, Sodium (Na+) level and anion gap were higher in non-survivors than survivors
group which were statistical significant (p < 0.05). No statistical significant different regarding PCO2, PO2, potassium (K+) and chlo
ride level (p > 0.05). Multivariable logistic regression analysis identified a higher AG (OR 1.321, 95% CI 1.14-1.53; p < 0.001) at the
time of admission in NICU as predictor of mortality.
Conclusion: A higher AG (anion gap) at the time of admission in NICU identified as strongest predictor of mortality.
