The blood urea nitrogen was elevated to 30 mg. per cent or more in about two-thirds and to 50 mg. per cent or more in about one-fifth of one hundred and thirty-five cases of hematemesis or melena due to various causes. In no instance of hematemesis due to peptic ulcer, hepatic cirrhosis, gastritis, carcinoma, or undetermined cause, did death occur as the result of the hemorrhage in the absence of an increased blood urea nitrogen content. In the presence of azotemia five of eight patients with hepatic cirrhosis died as did seven among thirty-five patients with peptic ulcer (including one patient who died of perforation). In the presence of azotemia shock increased the mortality rate in patients with hematemesis or melena. The mean maximum blood urea nitrogen was higher in patients fifty years of age or over than in those below this age limit. In patients with repeated or continued hemorrhages which proved fatal the already elevated blood urea nitrogen generally continued to rise or fluctuated above normal limits instead of reaching a maximum concentration in twenty-four to forty-eight hours and then dropping to normal on the third or fourth day as in patients with a single non-fatal hemorrhage.
