Traumatic Brain Injury Generates Biphasic Hemodynamic Responses in the Swine

摘要

The cardiovascular performances of 10 male Yorkshire swine were investigatedfollowing moderate to severe brain trauma that was induced by a fluid percussion device. Arterial pressure, cardiac output, heart rate, and pulmonary arterial pressure reached their highest values 20 seconds after brain trauma. Except for the heart rate, these cardiovascular variables dropped below their baseline values 2 hours after the trauma. These data indicate that brain trauma may significantly suppress cardiovascular performance.... Brain trauma, Hemodynamics.
