Abstract:Urea production rate and cellular Immune reactivity measured by skin stamp tests were used to determine the extent of protein catabolism in 30 surgical patients with histologically diagnosed gastrointestinal carcinoma. All patients received high‐caloric total parenteral nutrition (TPN) preoperatively. In those patients with an urea production rate of less than 15 g/day (according to definition a non‐catabolic state) TPN was discontinued and the operation performed immediately, whereas the remaining 13 patients… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
