ESOPHAGEAL COOLING AS A TECHNIC OF SELECTIVE BRAIN HYPOTHERMIA
SCHOOL OF AEROSPACE MEDICINE BROOKS AFB TX
Pagination or Media Count:
An experiment using 17 mongrel dogs was performed comparing the production of selective brain hypothermia by esophageal cooling alone and with external neck cooling. A second experiment on 4 of these dogs, using the latter technique compared the effects of increased carbon dioxide inhalation and bilateral vertebral artery ligation on the production of selective hypothermia. Although selective brain hypothermia was achieved in all animals to varying degrees, it was not of a sufficient magnitude to be recommended for clinical use. The clinical and pathologic changes are described.
