the purpose of this study will be explore the impact of data obtained for the arterial blood gas parameters and serum bicarbonate and electrolytes at the time of hospital admission on adverse clinical outcomes ,duration of length of hospital stay and mortality in patients with cirrhosis .Furthermore incorporation these parameters into model of end stage liver disease could help to improve the prognostic value of MELDscore in comparison to the prognostic value of traditional equation of original MELD and child score
1-to identify the prognostic value of serum bicarbonate and serum electrolytes at time of admission and their association with development of complications ,length of hospital stay ,prognosis and mortality in hospitalized cirrhotic patient
