Randomized Controlled Trial
Effects of preoperative carbohydrate loading on glucose metabolism and gastric contents in patients undergoing moderate surgery: a randomized, controlled trial.
Despite contrary evidence, the practice of overnight fasting before elective surgery maintains its place in tradition. However, prolonged starvation, by its catabolic action, may increase the detrimental effects of surgery. In this study, we evaluated the effects of preoperative carbohydrate loading on the gastric contents of patients and perioperative metabolism. ⋯ The preoperative intake of carbohydrate-rich fluids does not appear to alter the amount or pH of gastric contents, suggesting that this is a safe procedure, in terms of aspiration risk. Furthermore, the intake of such fluid might prevent energy malnutrition.

We evaluated the practice of nutritional therapy (NT) by NT multiprofessional teams (NTMTs) in hospitals of the São Paulo metropolitan region to verify its adequacy in meeting the legislation that regulates NT in Brazil. ⋯ The number of NTMTs in the hospitals of the São Paulo metropolitan area is below the requirement established by law; the existence of a NTMT is more frequent in medium and large hospitals; the purchase of the necessary supplies and equipment for the NT practice is more adequate in hospitals with non-public reimbursement; the NTMTs in non-public hospitals were found to be more competent than those in public hospitals in implementing enteral and parenteral nutrition; private hospitals offer better conditions for professional growth for a NTMT staff compared with public hospitals.
