Impact of varying levels of protein intake on protein status indicators after gastric bypass in patients with multiple complications requiring nutritional support

35 and no multi-system organ failure or fistulas, had complications after surgery requiring nutrition support services (NSS). Serum albumin and TBPA were matched to fed levels of protein using random coefficient regression analysis. Mean incremental increases of 2.34 mg/dl (TBPA, P=0.0113) and 0.11...

Description
Summary:35 and no multi-system organ failure or fistulas, had complications after surgery requiring nutrition support services (NSS). Serum albumin and TBPA were matched to fed levels of protein using random coefficient regression analysis. Mean incremental increases of 2.34 mg/dl (TBPA, P=0.0113) and 0.11 g/dl (serum albumin, P=0.0272) were found with each 0.5 g protein intake increase/kg ideal body weight/day (kg/IBW/day). Patients required NSS for 23+/-21 (mean+/-SD) days, with 15+/-19 days fed at goal rate. Initial serum albumin was 2.3+/-0.5, with a final measure of 2.7+/-0.5 g/dl. Goal protein and calorie intake were 2.1 g and 17 kcal/kg IBW/day versus actual intake of 1.6 g and 13 kcal/kg IBW/day. Morbidly obese patients requiring NSS following RYGBP risk iatrogenic protein malnutrition. There was a positive linear relationship between protein status and protein intake that warrants further study of higher protein feeding in complicated post-RYGBP patients.
