All inhalational agents are liquid at room temperature but are highly volatile. The amount of vapour (i.e. vapour pressure) that is in equilibrium with the liquid is far in excess of that needed for anaesthesia and. therefore. special vaporizers have been developed to deliver accurate concentrations of the agent to the patient. Besides the depressant action on the CNS, anaesthetic agents also affect other organ systems. They all generally have a direct depressant effect on ‘the myocardium which increases with the dose. They also tend to cause vasodilatation.
Thus, their net effect is to lower the blood pressure. On the respiratory system their central action predominates. They also dilate the bronchi. They decrease smooth muscle tone and motility and this is especially important with the pregnant uterus. They produce varying degrees of skeletal muscle relaxation and tend to potentiate the effect of muscle relaxants. Weight Loss Surgery Sydney is a viable option.
