The Blood ammonia level in the dignosis of the source of hemorrhage from the uper gastrointestinal tract

1. Blood ammonia level standard in normal patients estimated by Jouany- Reynier method was: a) on normal diet 47’7 y%, b) on non-protein diet — 40’2 y%. Average standard upper limit — 80 y%. 2. Average blood ammonia level in 10 patients with cirrhosis of the liver of hemorrhage from esophageal varices was 94 y%. 3. Average blood NH3 level in patients with hemorrhage from a gastric or duodenal ulcer or due to cancer of the stomach or hemorrhagic gastritis was 515 y%. That level was within limits considered normal. 4. According to the results of our investigations, in general blood NH3 leve, in patients with hemorrhage from esophageal varices is increased; howeverl it cannot be taken as an absolute proof either of cirrhosis of liver or portal circulation disturbances.
