Abstract		The aim of this study was to identify more effective way of intravenous fluids warming in the prevention of inadvertent hypothermia. We have compared conventional method of warming with warm water baths and new dry-heater system Hot- Line (producer: Smiths International Medical Systems Level -1). We have prospectively randomised 60 patients in two groups. First group received fluids warmed in water baths using conventional infusion systems. Second group received fluids using Hot-Line system. Temperature was measured in the esophagus, at the beginning of the operation and in 30 minutes interval till the end of the operation. Data were analysed using Student's T - test. Average temperature decrease was 0,44 degreesC for the water baths group and 0,04 degreesC for the Hot-Line group. This difference was statistically significant at p<0,001. Hot-Line system delivers fluid at constant temperature (40 degreesC). Double lumen infusion line prevents fluids cooling, with warm water, which is circulating in the outer lumen of the system. In the conventional infusion system intravenous fluid is cooled down before it reach the patient. The study has shown that Hot-line system is much more effective in preventing inadvertent intraoperative hypothermia then conventional methods.
