Abstract
A survey has been made of 210 cases of acute renal failure. The overall mortality was 37.1 per cent. Of the patients, 128 were male and 82 female, ranging in age from 5 to 79 years. The clinical, biochemical and other data were compared statistically, and factors affecting the prognosis in these patients were evaluated prospectively. Some major factors have been identified as having an adverse influence on prognosis, namely age, sex, etiology of acute renal failure, maximal blood urea nitrogen, and complications. Mortality rate rose with age, being especially high in those patients over the age of sixty, and was twice as high for male as for female, probably due to the preponderance of females in the etiologic group with the lower mortality rate and maybe due to unknown factors. Mortality was high in post traumatic group and postsurgical group, especially gastrointestinal and brain surgery. Blood urea nitrogen. mortality rose with the daily rise of BUN, but was not statistically significant. Maximal level of BUN was high in the poor prognosis group. Complications: infections, especially septicemia and pneumonia, gastrointestinal hemorrhage, congestive heart failure, coma had an adverse influence on prognosis.
