Although blood viscosity would have been increased in both groups with profound hypothermia, the likelihood of microvascular sludging with resultant cerebral ischemia and infarction may have been greater in the group subjected to total circulatory arrest. Hemodilution improves the rheologic characteristics of blood at low temperatures² and is safe because of the decreased demand for oxygen and, hence, hemoglobin for the . . .
