Efficiency of the Thermal Jacket on the Delivered Temperature of Prewarmed Crystalloid Intravenous Fluid
Abstract
A quasi-experimental research design was used to determine the relationship between the flow rate and the delivered temperature of prewarmed crystalloid intravenous solutions when using the Thermal Jacket, an insulation device designed for intravenous fluid bags, as compared to a conventional blood warning apparatus. One control and three experimental groups were used. Fluids in Group 1 (control group), Group 2, and Group 4 were prewarmed in a microwave oven to 41.45 + or- 1.05 C. Fluids in Group 3 were left near ambient room temperature and measured at 22.05 + or - 0.45 C. Fluids in the control group were infused through a standard intravenous pump tubing, 270 cm in length, using no temperature maintenance device. Fluids in Group 2 and Group 3 were delivered through a standard intravenous pump tubing connected to a blood warming coil which was immersed in a water bath blood warmer. The distance from the exit point of the blood warmer to the distal end of the infusion line measured 174 cm. Fluids in Group 4 were placed in a Thermal Jacket and delivered-through standard intravenous pump tubing. After a baseline measurement, temeperatures were recorded for all groups at two sites at 10 minute intervals over a 60 minute period. One site was the lower portion of the IV solution bag, and the other site was a point 2 cm from the distal end of the infusion set. Temperatures were at flow rates of 100, 250, 500, 750, and 1,000 ml/ hr for each group.
