Critically ill asthmatics that require mechanical ventilation may benefit from halothane and other inhalational agents. Various methods of administration of halothane have been tried. Anaesthetic machines are commonly used but are resource-expensive.
We used a simple in-line Oxford Miniature Vaporiser (OMV), as part of the inspiratory limb of a Servo 300 (Siemens) mechanical ventilator. We employed this device in three patients for a total duration of 120 hours without adverse effects.
We used the OMV as part of a regular positive pressure ventilatory circuit. The OMV was specially calibrated for halothane and was robust and reliable. Halothane delivery was controlled and in steady fashion; a simple wall-suction unit scavenged the exhaled halothane. Staff acceptance and user-friendliness were high. We recommend the OMV for regular ICU use for halothane in asthma.
