Abstract: | The nutritional value of regimes enriched with branched chain amino acids has been evaluated in 22 adult patients suffering from acute post-traumatic renal failure. The study was carried out for 12 days. The following data were recorded and compared daily: nitrogen balance, daily blood urea nitrogen (BUN), BUN/creatinine ratio, and plasma albumin levels. Also after 6 days of dialysis and nutritional support, the plasma medium molecular weight compounds (uremic toxins) were studied. It was concluded that: (a) the combined use of parenteral and oral nutrition appears most adequate in this type of patient; (b) the nitrogen intake should provide an essential amino acid/total nitrogen ratio of greater than or equal to 4 and a branched chain essential amino acid ratio of greater than or equal to 0.5; and (c) caution is still necessary in interpreting analyses of middle molecular weight compounds in this type of patient. |
