From: Effect of propofol and etomidate on normoxic and chronically hypoxic pulmonary artery
Relaxant effect of etomidate and propofol on rat aorta rings. Left panel: aorta rings from normoxic rat. Right panel: aorta rings from CH rat CH Abscissa: log concentration of anaesthetics (M). Ordinate: isometric contraction (% of the paired temporal control unexposed rings). Full circles: rings exposed to etomidate. Open circles: rings exposed to propofol. A: rings precontracted with 100 mM KCl. B: rings precontracted with 10 -6M PHE. Each symbol is mean value from 5 to 8 rats. Vertical bars are SEM. # P < 0.05 (overall comparison of etomidate versus propofol).
