[Use of an electronic gravity infusion regulator for infusion therapy in routine conditions. Comparative clinical...

In comparison with the ordinary roller clamp the gravity-infusion controller allows a significant lowering of complications and start-ups at peripheral venous access sites. These results are effectively based on a decrease in the infiltration rate of about 30%. For approximately 80% of the remaining complications an early alarm and interruption of the infusion takes place. It is of importance that the electronic controller avoids the excessive variations of the drop rate found with roller clamps. In contrast to these advantages problems may arise under certain circumstances caused by the narrowing of the control range based on the limited available hydrostatic pressure. Application of the electronic gravity controller must be seen primarily for peripheral venous access sites. Its use is particularly advantageous where an infiltration of the infusion solution results in an endangering of the patient (cytostatic agents, strong alkaline solutions, for instance NaHCO3, potassium concentrates, medication additions, for instance vasoconstricting agents). In addition, it makes sense to use the controller in situations where the accuracy of an infusion regulated by a roller clamp is considered to be inadequate.
