title: [Temperature behavior of infusion solutions].
abstract: Since rheological qualities (density, viscosity) of solutions depend upon temperature and consecutively influence the conditions of current, i. e. among others the dropping speed of the solutions to be infused, the behaviour of the temperature of the solutions glucose 50, 200, alvesin "new", fructose 400, intralipid 10%, sorbitoli 100, electrolytic infusion 153 DAB 7 and as comparative fluid distilled water was investigated. All solutions showed qualitatively the same behaviour. In an infusion not running after 3 till 4 hours at all levels of the infusion bottle an assimilation of the temperature of refrigerator to room temperature is to be expected. In running infusion after about one hour the infusion solution in the canule reaches room temperature, whereas the temperature of the solution in the infusion bottle is about 10 degrees C lower. With increasing speed of infusion this difference in temperature decreases. A constancy of the rheological qualities of an infusion solution is, therefore, in non-running infusion to be reached after about three hours, in running infusion after about one hour, in case that before the solution had the temperature of the refrigerator (4 degrees C till 10 degrees C). The dropping speed is influenced in such a case only by the changing of the hydrostatic pressure.
