To determine the predictive value of the index of peritonitis of Mannheim in patients with peritonitis in the Hospital Nacional Cayetano Heredia.A prospective study appears, of 103 patients, greater of 14 years, with I diagnose of peritonitis, between November 2004 to April 2005. For its analysis I am used the square test of chi with coefficient of Pearson, and the test of T of student. For the analysis of the data two modalities were used, the first patients were divided in 3 groups, according to the value of the index of Mannheim,21, of 21 to 29, and29, and in 2 groups, d 26 and26 points. I am made considered of survival of Kaplan the Meier, using statistical program STATA 8.0a mortality of 50% in patients with greater index of 26 points was obtained. One was a sensitivity 95.9%, a specificity of 80%, with positive a predictive value 98.9% and a negative predictive value of 50%. When considering 3 groups,21, 21-29 and29 points, was a mortality of 60% in patients with greater index of 29. I am made a survival curve obtaining itself a significant difference with a p=0, 0098. Figure 2.We found that the classification in 3 groups presents statistically significant difference, reason why recommended its use for the evaluation and beginning of aggressive measures. |
