title: Hemodynamic and metabolic alterations in peripheral tissue during hemorrhagic shock.
abstract: In dogs subjected to hypovolemic shock (modified Wiggers model) severe enough to decrease the arterial flow in an isolated hind limb by two-thirds, a marked hyperglycemia (three times control) and an increase in blood glucose AV difference (ten times control) occur. Despite the decreased arterial flow, glucose uptake by peripheral tissues increased by a factor of three within one-half hour of hemorrhage and remained elevated for several hours. Presumably, the increased glucose uptake reflects the need for more energy substrate during the hypoxic conditions of the decreased peripheral blood flow.
