Most potent bronchodilator among inhalational anesthetic agents is
Effect of inhalational agents on respiratory systemAll inhalational agents are bronchodilators -Halothane cause maximum bronchodilatation. The inhalational agent of choice in asthmatics (intravenous anaesthtic of choice is ketamine).All inhalational agents cause respiratory depression to some extent - Maximum depression of respiration is seen with enflurane, on the other hand, maximum inhibition of ventilator response to increased CO2 and hypoxia is caused by halothaneAll inhalational agents vasodilate pulmonary vascular bed by blunting the hypoxic pulmonary vasoconstriction (HPV) response. Halothane has maximum effect: Isoflurane, Enflurane, desflurane, sevoflurane have similar effect.(Refer: Morgan and Mikhail's Clinical Anaesthesiology, 5th edition, pg no. 167 - 169)
