Methods and devices are disclosed for providing therapeutic hypothermia using irrigation of the aerodigestive tract with cooled liquids. The disclosed method provides much more rapid therapeutic cooling to lower temperatures than could previously be achieved, thereby improving clinical outcomes. Novel cooling liquids and cooling devices are disclosed for carrying out the method. An external turbulent flow of cooling liquid may also be applied to the exterior of the head to further promote heat exchange. Multiple embodiments of devices are disclosed for performing rapid induction and maintenance of therapeutic hypothermia either in a hospital setting or in the field so that hypothermic treatment can be quickly instituted before significant tissue damage occurs. Methods are also disclosed for targeting brain cooling by irrigating the upper airway/aerodigestive tract, and more generalized cooling by irrigating the esophagus and/or stomach. |
