Computer Optimization of Enteral Hyperalimentation

Abstract

A computer program has been developed to allow the generation of written orders for the logical progression of enteral hyperalimentation by the technique of continuous nasogastric infusion. Data required for entry include name, age, sex, height, usual and current weights, degree of stress, and if indicated, restrictions of nitrogen, fluids, sodium and potassium. A specific formulation may be requested, or the computer will pick a single nutrient solution or combination of two solutions that will best meet the requested constraints. Output includes entered data with English and Metric interconversion, surface area, and estimates of basal energy expenditure, protein wastage, protein and caloric requirements. If requested, daily orders are written to include a reasonable progression of infusion rates and concentrations of the solution (s). Daily values are printed for the total amounts to be infused of fluid, calories, protein, sodium, potassium, and mOsm. The programs have been demonstrated to run in either on-line or batch mode. The system is easily accessible by physician, dietician, nurse, or other interested professionals.
