Cerebrale Vasodilatation: Halothane > Isofluran (Isofluran ist beliebter in NCh)

Halothane boils at 50°C and has a saturated vapour pressure (SVP) of 32.3 kPa. The SVP is almost identical to isoflurane, and this may allow them be delivered using the same vaporiser, for example, Oxford miniature vaporiser.

All volatile agents inhibit hypoxic pulmonary vasoconstriction and therefore increase shunting.

Halothane sensitises the myocardium to circulating catecholamines and this is one reason why surgeons usually ask the anaesthetist prior to infiltrating epinephrine (adrenaline) containing local anaesthetics.

The minimum alveolar concentration (MAC) of halothane is 0.7%.
