OBJECT: The object of the present study is to examine how much the ferritin ratings could evaluate the maintenance of the nutritional balance in patients with heavy injuries (and under intestinal alimentation). For this purpose we have chosen multi-injured and burned patients. MATERIAL - METHOD: The sample study included a group of 66 patients. Thirty five (35) of them were multitraumatic patients and thirty one of them burned, taken care in hospitals in Athens. The duration of the study was two years. The method used for data collection was based on a specific protocol checking the effectiveness of enteral nutrition. Evaluation indexes of nutrition constituted total albumens, albumin, the absolute number of lymph cells, T.I.B.C. and ferritin. During the study blood specimens were taken for the evaluation of the above indexes. RESULTS: The data analysis has shown: * Significant increase in levels of total albumen -p<0,001 for multitraumatic patients and p<0,003 for the burned. * Significant increase in albumins p<0,005 in burned patients. In normal levels were the absolute number of lymph cells and T.I.B.C. The levels of ferritin were very increased up to 3000 mg in all counts and in both groups of sample study. CONCLUSION: The special increased levels of ferritn, which is a positive albumin of acute phase, would be followed by analogous decrease of the negative albumins of acute phase, the levels of which were remain normal. Therefore, ferritin could be a reinforcing evaluation index of the nutritional equilibrium in acute patients phase due to severe trauma.
