Very early nutrition supplementation in burned patients

We studied some metabolic and hormonal effects of a very early nutrition supplementation in burned patients. The patients were divided into two groups of 10 patients each. Supplementation in the first group, the very early nutritionally supplemented (VENS) group, was started immediately after admission, ie, after 4.4 +/- 0.5 h (mean +/- SEM) from the injury; it was started after 57.7 +/- 2.6 h from the injury in the second group (control group). Hormonal and metabolic indices were recorded every 4 d up to 28 d. In the VENS group, the nitrogen balance became positive in 8.8 +/- 4.1 d whereas it took 24.1 +/- 6.9 d in the control group (p less than 0.05). Urinary catecholamine excretion and plasma glucagon concentrations were lower during the first 2 wk of observation in the VENS group compared with the control group. Insulin concentrations were significantly higher on the fourth and eighth days in VENS patients and plasma cortisol concentrations were similar in both groups.
