SINGLE BREATH INDUCTION OF ANAESTHESIA WITH ISOFLURANE

This study has compared a single breath induction techniqueand a conventional inhalation induction technique using isofluranein nitrous oxide and oxygen. Each group consisted of 36 unpremedicatedpatients. Single breath induction was associated with fewerproblems on induction, but required more patient co-operation.Ninety-four percent of patients were willing to repeat the singlebreath induction technique, compared with 74% of patients receivinga conventional inhalation induction. ^*Present address, for correspondence: The Sir Humphry Davy Departmentof Anaesthesia, Bristol Royal Infirmary, Bristol BS2 8HW.     

The management of anaesthesia for patients with cystic fibrosis

The clinical problems of patients with cystic fibrosis who require anaesthesia are reviewed. The management and the complications of anaesthesia in 77 patients over a 3-year period are presented. The long term effects of anaesthesia are analysed by a study of the lung function tests of these patients. The results suggest that even multiple procedures, as for instance nasal polypectomy, are not harmful. A method for safe peroperative management is presented.
