[A 5-year interval report on study of burn metabolism and nutrition]

This paper introduces the essential experiences concerning studies of burn metabolism and nutrition in our institute in the past five years. 1. Three new and practical animal models were developed for studying gastro-enteral nutrition in burns. 2. With indirect calorimetry, resting energy expenditure (REE) of 92 burn adult patients were measured and analyzed, and on the basis of which a new formula for calculating nutritional supplement in Chinese burn adults was proposed: kcal/day = 1,000 x M2 (body surface area) + 25 x % TBSA (total burn surface area). 3. Through experimental and clinical studies, it was found that antiouperoxide agents (such as SOD, CAT), tolbutamide, glutamine and Chinese herb decoction Sizunzituang all exhibited modulating effects on postburn metabolism and nutrition, e.g. decreasing catabolism, reducing negative nitrogen balance, stimulating secretion of insulin, enhancing tissue utilization of glucose, maintaining the mass of enteral mucosa and improving functions of viscerae. 4. A new less irritating, simple and easy-to-introduce nasal-enteral nutrition tube was devised, which could pass through the pylorus easily into the duodenum usually within 6hrs without using a stylet. It would be useful in the early postburn enteral nutrition supplementation.
