Background: Giving unwarmed fluid or blood to the patients during surgery under general anesthesia may decrease the patients’ temperature. Objective: To compare the effectiveness of each intravenous warming device with different flow rates. Methods: Five types of intravenous warming device were evaluated at different fluid flow rate. Mean and repeated measures ANOVA were analysed the data. Results: Intravenous fluid warming with force air warming was the most effective device and at flow rate 50, 100, 500 ml/hr. (p = 0.000). Dry heat plate was effective only at higher flow rate (1,000 ml/hr) (p < 0.05). Conclusion: Choice of intravenous warming devices depends on the cost effectiveness of each device and flow rate of fluid. Choosing the device that works well at each flow rates will improve the quality of the patients care.
