Reviewing recent medical literature, I came across an interesting study from Europe. The investigators in several European cities were using an intranasal cooling device to cool the patients having cardiac arrest. I am myself very interested in cooling cardiac arrest patients. There is a body of evidence that the patients have better neurological outcomes when therapeutic hypothermia (cooling to 32 – 33 degrees Celsius) is utilized. I have been using an intravascular cooling system in my ICU. When cooling is being initiated in ICU, there is always a delay in time. The sooner this treatment is started the better our chances on preserving the neurological function. Ideally, the cooling should be initiated immediately at the scene. Using cooling packs and cold saline is somewhat cumbersome and might interfere with the resuscitation. A company from San Diego came up with an intranasal cooling device called RhinoChill to provide cooling immediately after the cardiac arrest. It sprays a rapidly evaporating chemical onto nasal mucous membrane, thus, cooling it down. It does make sense physiologically. The inner surface of the nose is reach in vascular supply and it’s proximity to the brain makes it an ‘ideal’ place for cooling. The data is promising so far. If it goes mainstream, we might see it next to the cardiac defibrillators at the airports (just kidding).
