Local anaesthesia and sedation for rigid bronchoscopy for emergency relief of central airway obstruction

Summary We report three experiences that illustrate the use of local anaesthesia for rigid bronchoscopy. All patients were acute emergencies, with life‐threatening central airway problems. Instruments were inserted after the airway was anaesthetised using a technique that owes much to mid 20th Century methods for inserting endobronchial blockers. There is discussion about requirement to preserve and conserve self‐ventilation and the securing of compromised central airways without the aid of neuromuscular blocking agents. Historical aspects of bronchoscopy are reviewed. Concomitant sedation reduced the unpleasantness of the experience in a way that in the past could only be dealt with by careful attention to the humanitarian elements of detail. Problems of oxygenation were ameliorated by periodically superimposing intermittent jetting with a Sanders injector fed from the oxygen pipeline. A need for developing and refining topical and other local anaesthetic techniques for rigid bronchoscopy is anticipated with the expansion of services for tracheo‐bronchial stenting and lasering.
