Critical illness precipitates a marked catabolic response, with protein wasting and loss of lean body mass. Prolongation of this response leads to impaired immunity, poor wound healing, loss of intestinal barrier function and muscle weakness, thereby increasing morbidity and perhaps mortality. Conventional nutritional support only partially ameliorates this process. Disappointingly, specific anabolic and anticatabolic strategies have so far met with only limited success, although recent findings, in particular studies demonstrating the potential value of aggressive insulin therapy and the administration of growth hormone secretagogues, have been encouraging.
