Effects of early enteral feeding containing medium and long-chain triglyceride on improving protein catabolism of burned patients / 肠外与肠内营养

ABSTRACT

ObfectivesThe purpose of the present study was to compare the effects of different early enteral nutrition formula (containing either MCT/LCT or LCT only) on improving nutritional status of burned patients. Methods:This was a prospective,randomized,single blind and controlled study.Thirty cases of burned patients injured by varous causes with total burn surface area (TBSA) more than 30% were collected and randomized into two groups①Group Fenteral feeding with Fresubin 750 MCT containing MCT/LCT as fat source,②Group Nenteral feeding with Nutrison,containing only LCT as fat source.All of the thirty patients received isocaloric,isonitrogenous,and isolipidic enteral feeding,with intragastric tube and enteral feeding pump,started within 24 h postburn.The several parameters were observed on postburn day(PBD) 1,4,7 and 10,such as serum concentrations of transferrin and prealbumin and plasma concentrations of prostaglandin E 2(PGE 2) and insulin.Nitrogen in urine per day and excretion of 3 methylhistidine in urine on day 1,7 and 10 postburn were determined. Results:The results showed that the patients of F group had an increased blood concentration of transferrin,prealbumin and insulin,and a decreased plasma concentration of PGE 2.Excretion of nitrogen and 3 methylhistidine in urine was also markedly reduced in patients fed with nutrients containing MCT/LCT compared with LCT. Conclusions:We have shown that an enteral diet containing MCT/LCT can improve the nutrition status of burned patients more effectively.
