Thirty-five patients who had undergone uncomplicated cardiac surgery w ere randomly allocated to receive either Entonox or isoflurane 0.25% i n Entonox as inhalational analgesia for the removal of their two chest drains. The gases were presented premixed in high-pressure cylinders and were self-administered by means of a demand valve. The removal of the second drain was more painful than the first but that pain was bet ter controlled by isoflurane 0.25% in Entonox than by Entonox alone.
