| Summary: | <p id="p1">Magnetic resonance imaging (MRI) in veterinary patients requires general anesthesia to limit movement during imaging. Hypothermia is a very common complication in small animals under anesthesia and can lead to a variety of adverse events, including delayed recovery, organ dysfunction, decreased immune function, blood coagulation abnormalities, and decreased metabolism. Specifically, hypothermia during MRI examinations is difficult to prevent or reduce during MRI examinations under anesthesia, as there are no commercially available electrical warming systems specifically designed for use in MRI rooms, which impacts recovery and overall health. This chapter examines various methods for preventing hypothermia in small animals undergoing MRI examinations under general anesthesia and provides comprehensive insights into the limitations of current hypothermia prevention practices and introduces novel approaches, such as the use of insulation devices, heat and moisture exchangers (HMEs) and α<sub>2</sub> adrenergic receptor agonists like dexmedetomidine, which can maintain rectal temperature effectively during prolonged anesthesia.</p> |
