Abstract: Background: Perioperative hypothermia is a common occurrence, particularly with the elderly and pediatric age groups. Hypothermia is associated with an increased risk of perioperative complications. One method of preventing hypothermia is warming the infused fluids given during surgery. The enFlow i.v. fluid warmer has recently been reintroduced with a parylene coating on its heating blocks. In this paper, we evaluated the impact of the parylene coating on the new enFlows fluid warming capacity. Methods: Six coated and six uncoated enFlow cartridges were used. A solution of 10propylene glycol and 90distd. H2O was infused into each heating cartridge at flow rates of 2, 10, 50, 150, and 200 mL/min. The infused fluid temperature was set at 4掳C, 20掳C, and 37掳C. Output temperature was recorded at each level. Data for anal. was derived from 18 runs at each flow rate (six cartridges at three temperatures). Results: The parylene coated fluid warming cartridge delivered very stable output of 40掳C temperatures at flow rates of 2, 10, and 50 mL/min regardless of the temperature of the infusate. At higher flow rates, the cartridges were not able to achieve the target temperature with the colder fluid. Both cartridges performed with similar efficacy across all flow rates at all temperatures Conclusions: At low flow rates, the parylene coated enFlow cartridges was comparable to the original uncoated cartridges. At higher flow rates, the coated and uncoated cartridges were not able to achieve the target temperature The parylene coating on the aluminum heating blocks of the new enFlow i.v. fluid warmer does not neg. affect its performance compared to the uncoated model. In the experiment, the researchers used many compounds, for example, 1,2-Propanediol (cas: 57-55-6Computed Properties of C3H8O2).
1,2-Propanediol (cas: 57-55-6) belongs to alcohols. Because alcohols are easily synthesized and easily transformed into other compounds, they serve as important intermediates in organic synthesis. Tertiary alcohols cannot be oxidized at all without breaking carbon-carbon bonds, whereas primary alcohols can be oxidized to aldehydes or further oxidized to carboxylic acids.Computed Properties of C3H8O2
