Abstract

The main advantages of infusion pumps are their enhanced accuracy and safety in providing enteral nutrition. We proposed to observe pumps reliability in connection with a variety of factors such as the type of pump used, the administration rate and the energy density of the diets used. An experimental design was prepared with two types of enteral nutrition pumps-VP, volumetric pump, and PP, peristaltic pump. The clinical simulation was done by connecting the enteral nutrition equipment to a graduated dosing system, making hourly measurements of the volume infused. The Reliability Index (RI) used was the ratio between the volume infused by the pump and the regulated dose (Vi/Do). Five volumetric pumps (FLEXIFLO COMPANION) and five peristaltic pumps (FLEXIFLO II) were selected at random from a single commercial outlet. Each was used for twenty-three hours, without interruption, to infuse five types of diet with different energy densities (D1:2 Kcal/ml, D2: 1.5 Kcal/ml, D3: 1.25 Kcal/ml, D4: diet with fibre, and D5: reconstituted powder diet) at three different flow rates (40, 80 and 120 ml/h), to provide fifteen experimental conditions with each pump. Reliability was maintained for both types of pump within the margin of error claimed by the manufacturer (+/- 10%) except in the first hour of infusion (RI = 71.4%). Comparison of the overall RI between the two pump types revealed significant differences, with an RI below the reference range for the VP only during hour 23 (p < 0.001).(ABSTRACT TRUNCATED AT 250 WORDS)
