In defined study period, neonates with serumsodium level >145mmol/L, who satisfies all the inclusion criteria are included in the study.' The data was collected using a proforma which included clinical symptoms, risk factors for neonatal hypernatremia in addition to laboratory data.
Results:
The results demonstrated hypernatremia in 63 neonates with mean age of presentation being 4.5 days, mean sodium level of 154.2 and average weight loss was 13.2%. Neonates admitted at older age >7days had higher sodium concentration with mean of 162.5mmol/L. Serumsodium levels correlates positively with percentage of weight loss and correlates negatively with birth weight and was statistically significant with p value <0.05. 41(65%) of mothers were primipara, 37(58%) had delivered by LSCS and 39(62%) had lactation issues postnatally. Most common presenting symptom was jaundice in 44(71%), followed by fever in 38(61%).
