Background: To assess serum sodium levels in liver cirrhosis patients. Materials & methods: A total of 100 patients were enrolled. Only those confirmed cases of cirrhosis of liver were enrolled. Complete demographic and clinical details were recorded. Grading of all the patients according to Child-Pugh Score grade was done as follows- Class A, Class B and Class C.serum levels were obtained and were the biochemistry lab where auto-analyser was used for evaluation of serum sodium levels. Results: Mean serum sodium levels were found to be 128.4 mmol/L. Hyponatremia was found to be present in 58 percent of the patients. While correlating the occurrence of hyponatremia with Child-Pugh score, significant results were obtained. Conclusion: Hyponatremia might indicate the existence of severe complications associated with liver cirrhosis.
