Effects of total parenteral nutrition enriched with branched chain amino acid infusion on liver function and serum amino acid pattern in dogs undergoing hepatectomy.

In order to study effects of different total parenteral nutritional regimens on the recovery of liver function and on plasma amino acid pattern after major hepatectomy, twelve healthy mongrel dogs were submitted to 70% liver resection and randomly divided into three different groups: group I (control group) received only 10% glucose; group II received 10% glucose plus 8.5% Freamine; group III received 10% glucose plus 100% branched chain amino acid (BCAA) solution. Blood samples were analyzed for determining biochemical parameters, including plasma amino acid levels, before surgery and on 3rd and 7th postoperative day.
