Preservation of the hypoxic pulmonary vasoconstrictor mechanism during methoxyflurane anaesthesia in the dog.
The effect of methoxyflurane on the hypoxic pulmonary vasoconstrictor response in the dog lung was assessed by measuring the redistribution of pulmonary blood flow in response to two levels of unilateral alveolar hypoxia. Methoxyflurane 0.5% had no significant effect on the redistribution of blood flow resulting from the unilateral administration of oxygen 7% or nitrogen and there were no significant differences in PaO2 between the measurements made during unilateral hypoxia with methoxyflurane and those made during unilateral hypoxia in the control periods.
