This study is an integrative review and aims to verify the main findings on the ideal amount of protein in the nutritional therapy of critically ill patients in order to stimulate positive nitrogen balance. The articles selected for this review indicated that a high-protein diet, with 1.2 to 2 grams of protein per kg of weight, is related to better results in nitrogen balance, as well as more favorable clinical outcomes, such as shorter mechanical ventilation time, ICU stay, hospital stay, in addition to reducing mortality. Thus, it can be concluded that a high-protein diet stimulates positive nitrogen balance. However, the ideal amount of protein for this stimulus is controversial in the literature, due to the multiple specificities of intensive care patients.
