Abstract
Fibreoptic intubation has been suggested to be the best method to manage a compromised airway. This retrospective study was designed to compare endotracheal intubation with the help of a rigid laryngoscope or a fibrescope in patients with rheumatoid arthritis. Intubation difficulties with the laryngoscope and the fibrescope in patients with rheumatoid arthritis were investigated during a period of five and a half years. The anaesthesia records were used for analysis. The patients were divided into two groups (group I with 41 patients and group II with 37 patients) reflecting the change in the routine airway management in patients with rheumatoid arthritis in our hospital from the beginning of 1993. Before that time the patients were usually intubated orotracheally under general anaesthesia, but since 1993 rheumatoid patients with anticipated difficulties in endotracheal intubation have been preferably intubated fibreoptically awake under sedation and topical anaesthesia with a fibrescope. Major difficulties in endotracheal intubations were encountered in 13% of patients in group I and in 8% in group II. On two occasions in group I tracheostomy was needed. In one of these patients, emergency tracheostomy was performed. In the latter group, the main reason for prolonged fibreoptic intubations was lack of experience. The introduction of fibreoptic intubation technique has had a favourable influence on the safety in the airway management of surgical patients with rheumatoid arthritis.
