Nitrogen balance, Protein intake, Intensive careAbstract
This review aims to identify key findings regarding the optimal protein supply required to stimulate nitrogen balance and positive nitrogen balance in critically ill adult patients. This is an integrative review study, with the inclusion of 4 original articles selected from PubMed and Cochrane databases. The data were synthesized and organized in a table. The main findings evidenced are that a higher protein intake is associated with better results in nitrogen balance, lower mortality and increased survival. It is concluded that all studies included in this review agreed that a greater increase in protein supply stimulated positive nitrogen balance, however the ideal amount of protein intake is still controversial in the literature, indicating a gap for future research
