SummaryBackground & aimsNutritional therapy is particularly important after major burn injury and specific nutritional guidelines have been developed. The study aimed at evaluating the impact of the changes in our nutritional practice, general compliance with the guidelines and potential consequences.MethodsRetrospective analysis of prospectively collected data in burn patients requiring intensive care (ICU) between 1999 and 2014. Inclusion criteria: admission on day 1, full treatment and length of ICU stay >7 days. Four periods (P) were defined by protocol changes (P1: 1999-2001, P2: 2002-2005, P3: 2006-2010, P4: 2011-2014). Collected data: demographic and nutritional data, infectious complications, weights, CRP and prealbumin concentrations during the first 21 days.Results240 patients were included (median age 43 years, burned area 25%). Measured energy expenditure (MEE) was stable through all periods but the prescribed caloric target decreased significantly, and below MEE (P1: 33 kcal/kg, IQR 7, P4: 28 kcal/kg, IQR 8, p < 0.001). Energy delivery ended decreasing below 30 kcal/kg/day (P1: 30 kcal/kg, IQR 23, P4: 25 kcal/kg, IQR 12, p < 0.001). Protein intakes increased due the use of high protein solutions and glutamine (P1: 1.04 g/kg, IQR 0.90, P4: 1.26, IQR 0.99, p < 0.001). Weight loss by day 21 increased significantly according to area under the curve (P1: 701, IQR 38, P2: 722, IQR 51, P4: 689 IQR 63, p = 0.02). Prealbumin levels decreased with energy decrease (P1: 150 mg/L, IQR 110, P4: 80 mg/L, IQR 70, p = 0.003).ConclusionsThe observed reduction of the energy delivery <30 kcal/kg was associated with a supplemental weight loss and lower prealbumin concentrations.
