Change in adrenomedullary function in artificial hypothermia


, : Change in adrenomedullary function in artificial hypothermia. Fiziol Zhur Sssr [Transl] 45(9): 77-82

In the presence of profound inhibition of the central nervous system the cooling process with artificial hypothermia in dogs and with hypoxic-hypercapnic hypothermia in albino rats was not accompanied by increase of adrenaline or noradrenaline secretion. Deeper hypothermia (to 26-27[degree] C for dogs and lower for rats) led to reduction of adrenomedullary activity. The development of disturbances of cardiac action and, more particularly, fibrillation of the heart, which are often seen in artificial hypothermia, is not connected with increase of adrenaline or noradrenaline secretion.
