Eelectrocardiographic findings during bronchoscopy. Use of the Sanders' ventilating attachment

The incidence of cardiac dysrhytmias was investigated in 50 patients during bronchoscopy performed under general anaesthesia using the bronchoscope with Sanders ventilating attachment. The results were compared with similar investigations utilising alternative methods of anesthesia. Sinus tachycardia occurred frequently, but was less severe than during previous investigation. The incidence of dysrhytmias 16% overall, was less than with earlier methods. Only 2 patients (4%) exhibited a dysrhythmia of any significance. It is concluded that use of the Sanders ventilating attachment represents a genuine advance during anaesthesia for bronchoscopy.
