Abstract/OtherAbstract:
Renal cortical tissue gas tensions, systemic oxygen supply and some features of energy metabolism and central hemodynamics were recorded in splenectomized dogs during graded hemorrhage and subsequent reinfusion of shed blood. Renal cortical partial pressure of oxygen and carbon dioxide responded rapidly to changes in blood volume and cardiac output. Lowest cortical partial pressure of oxygen values and highest cortical partial pressure of carbon dioxide levels were achieved at a maximal 50 percent blood loss. The decrease in arterial pressure, blood hemoglobin and hematocrit as well as the increase in blood lactate concentration lagged behind blood loss. Renal cortical partial pressure of oxygen, arterial pressure and cardiac output responded rapidly to reinfusions of withdrawn blood, while the cortical partial pressure of carbon dioxide, heart rate, arterial pH and blood lactate concentration returned to initial levels more slowly. Arterial blood gases remained normal throughout the observation period and did not provide an adequate index of tissue oxygenation. In contrast, the partial pressure of oxygen of the renal cortex proved an excellent and sensitive indicator of renal perfusion during hemorrhagic shock and its management.
