� Hemodynamisch:

� Lage conc.: Sympatholysis: BD + HR�(α2A), adrenaline � (α2C)

� Hoge conc.: BD � (α2B), SVR �, Cardiac Output �

� Respiratoir: MINIMAAL!

� Neurologisch: Sedatie (α2A)

� Analgesie: linearly decreasing pain sensation and MAP

Conclusie:

� Positieve invloeden op ischemie/reperfusie

� Hemodynamisch stabiliserend

� Opiatennood �, mortaliteit � , delirium �

� Postoperatief sedatie zonder respiratoire depressie,

significante daling HR
