Key result
Ground squirrel hibernation arousal centralizes blood flow to thoracic and anterior tissues unlike hypothermic rats.
Why the study?
The regional organ or tissue blood flows during arousal from hibernation in the 13-lined ground squirrel were not previously estimated.
The study demonstrates a centralization of blood flow to thoracic and anterior tissues during arousal from hibernation in ground squirrels, a mechanism absent in hypothermic rats.
No takes yet. Share an insight, caveat, or question.
Should not change clinical hypothermia management; leaves open mechanistic studies of regional perfusion in arousal models.
Bullard et al. (1962) studied Arousal from hibernation. Arousal from hibernation vs. Control flows / hypothermic state in rat was evaluated on Regional blood flow estimated by rubidium 86 distribution. Arousal from hibernation in ground squirrels centralizes blood flow to thoracic and anterior tissues, a phenomenon not observed in hypothermic rats.
