Abstract
A volume-pulse plethysmograpbic study of the behaviour of the blood vessels of the human face has shown that halothane anaesthesia causes vasodilatadon of the vessels of the nose and vasoconstriction of the vessels of the cheeks. The reactions of the blood vessels of the nose to anaesthesia are similar to those of the fingers and may therefore be regarded as being of the alpha-adrenoceptive variety. The vessels of the cheeks behave similarly to the vessels of the skeletal muscles and may be regarded as being beta-adrenoceptive. Isoprenaline causes active vasodilatadon of the cheek circulation in conscious subjects and does not have a similar effect on the blood vessels of the fingers.Keywords
