Vazão de cateter periférico in vitro

Abstract

Dehydrated or hypovolemic patients need electrolyte and blood volume expanders replacement. Besides the care to make adequate volume, especially in critically ill patients, it is essential that the rate of replacement is faithful to the calculation designed. This study aimed to evaluate, in vitro, flow catheters of different diameters of four trade-mark available in market, more used for fluidtherapy in domestic animals at the Veterinary Teaching Hospital of the Federal University of Santa Maria (UFSM). There were used bottles of 500 and 1000 mL of 0.9% saline solution and macrodrops intravenous set from the same brand. With this research it was concluded that the average flow of catheters does not match the data released on the sales packaging thereof; even though the same number, the flow rate varies with the brand of the catheter. The use of the infusion pump in cases of shock only provides the flow necessary for dogs up to 11.1kg.
