Selective versus standard hyperalimentation. A randomized prospective study.
Fifty consecutive surgical patients were included in a randomized prospective study to determine the relative advantages and disadvantages of two types of nutritional support systems: one, selective hyperalimentation, relies on a balanced substrate formula, while the other, standard hyperalimentation, depends on carbohydrate and protein to satisfy the energy requirements of the patient. The patients who received the balanced substrate formula had significantly fewer complications than those receiving standard hyperalimentation, even though both groups achieved positive energy and nitrogen balance. The enhanced safety of selective hyperalimentation suggests its therapeutic superiority as a basic nutritional support system for a busy surgical service.
