Lower Extremity Elevation to Minimize Hemodynamic Instability During Induction of General Anesthesia

Purpose

The purpose of this study is to determine if lower extremity elevation (LEE) will reduce the incidence of postinduction hypotension, to compare the utilization of vasoactive medications after induction in patients with LEE and patients without LEE and to determine if LEE will increase measured cardiac output

Condition

  • Post Induction Hypotension
