Differential effects of mild central hypovolemia with furosemide administration vs. lower body suction on dynamic cerebral autoregulation

摘要

We therefore evaluated dynamic cerebral autoregulation during equivalent central hypovolemia induced by furosemide administration and LBNP to test our hypothesis that mild hypovolemia has different effects on dynamic cerebral autoregulation, depending on the presence or absence of hemoconcentration, and that mild central hypovolemia due to furosemide administration enhances dynamic cerebral autoregulation in contrast to LBNP.
