[Prognostic factors in diffuse peritonitis].

In order to evaluate their prognostic relevance for survival 46 variables were submitted to univariate as well as multivariate analysis in a group of 184 patients with diffuse peritonitis. In the univariate analysis a significant correlation with the outcome was found for the following parameters: age greater than or equal to 70 years, preexisting hepatic or cardiac disease, no eradication of the primary source of infection at first laparotomy for peritonitis, cardiovascular instability, respiratory failure, hyperbilirubinemia, thrombocytopenia, elevated serum creatinine and diminished creatinine clearance at the beginning and proof of pseudomonas aeruginosa in the peritoneal exsudate and of candida albicans in the blood culture during the course of the peritonitis. In the multivariate analysis the surgical eradication of the primary source of infection at the first laparotomy for peritonitis, serum creatinine at the beginning of peritonitis, age greater than or equal to 70 years and a preexisting hepatic disease proved to be the independent variables with significant prognostic relevance for survival of the patients.
