Single breath induction of anaesthesia with isoflurane

This study has compared a single breath induction technique and a conventional inhalation induction technique using isoflurane in nitrous oxide and oxygen. Each group consisted of 36 unpremedicated patients. Single breath induction was associated with fewer problems on induction, but required more patient co-operation. Ninety-four percent of patients were willing to repeat the single breath induction technique, compared with 74% of patients receiving a conventional inhalation induction.
