Study on multiple acid-base disorders in patients with severe viral hepatitis / 第三军医大学学报

ABSTRACT

In order to evaluate the acid-hase disorders(ABD)in patients with severe viral hepatitis correctly,274 parameters of blood gas and electrolyte were analyzed.According to the combined analysis on the pre-estimated compensatory formula(PCF).anion gap(AG).and potential bicarbonate and chlorine,there were only 78 times of single ABD(28.5%),101 times of double ABD(36.7%),and 95 times of triple ABD(34.6%),which indicates that multiple ABD was quite common in patients with severe viral hepatitis.Among various forms of ABD.respiratory al-kalosis(222 times and 81.0%)was the commonest.then metabolic alkalosis(188 times and 68.6%).metabolic acidosis(136 times and 49.3%),and respiratory acidosis(20 times and 7.3%)occupied the 2nd.3rd.and 4th position on the list.The ratio between alkalemia and acidemia was 2.43 '?1.The incidences of complications and mortality were significantly higher in patients with mixed ABD than in those with simple ABD.
