RESUMEN
Seventy-two patients from one month to 15 years of age that according with the Modificated criterion of multiple organ failure (MCMOF) had two or more organ failures were studied. They were divided into two groups: Group I consisted of 55 patients that survived and group II of 17 patients that died. In both groups, the MCMOF was determinated upon admission and discharge, as well as the maximum obtained during the evolution. The comparison of both groups, with respect to the number of organic failures presented and the points of MCMOF showed highly significant differences with p less than 0.001, found in group I: 1.27 +/- 0.96 organ failures and a value of 4.84 +/- 2.92 of the MCMOF and in the group II: 3.84 +/- 1.59 organ failures and 25.68 +/- 7.57 points of the MCMOF respectively. The comparison between the number of organic failures at admission and discharge showed significant differences in both groups, having the tendency to decrease in group I from 1.87 +/- 1.01 to 0.56 +/- 0.60 and in the group II to increase from 3.41 +/- 1.46 to 4.35 +/- 1.45. The same phenomenon was observed for the values of the MCMOF with a qualification of 7.72 +/- 5.36 to 1.87 +/- 1.82 in a group I and from 18.94 +/- 10.31 to 33.38 +/- 8.27 in group II. Spearman correlation coeficient between the number of organic failures and values of the MCMOF showed and r = 0.99 and equivalent p less than 0.001, highly significant.
