Topical anaesthesia of the nasal mucosa for fibreoptic airway endoscopy.
We have compared four methods of topical anaesthesia of the nostril for fibreoptic airway endoscopy in a randomized study with 31 unpremedicated volunteers, each serving as his or her own control. Lignocaine spray, EMLA cream, three cotton swabs soaked in 4% lignocaine solution, or 2% lignocaine gel was applied in a nostril for 3 min. Application of lignocaine spray was rated as the most unplea...
متن کاملAnaesthesia for fibreoptic bronchoscopy.
Fibreoptic bronchoscopy is a useful diagnostic aid but may result in difficulties when associated with endotracheal anaesthesia. As a result, adequate ventilation may be difficult in patients with impaired pulmonary function and, in particular, in female patients because of the smaller size of the laryngeal opening. In a trial of three methods of endotracheal anaesthesia in a series of 39 patie...

متن کاملThe upper airway during anaesthesia.
Upper airway obstruction is common during both anaesthesia and sleep. Obstruction is caused by loss of muscle tone present in the awake state. The velopharynx, a particularly narrow segment, is especially predisposed to obstruction in both states. Patients with a tendency to upper airway obstruction during sleep are vulnerable during anaesthesia and sedation. Loss of wakefulness is compounded b...
متن کاملManoeuvres used to clear the airway during fibreoptic intubation.
Fibreoptic orotracheal endoscopy under general anaesthesia may be more difficult to perform if the upper airway cannot be fully cleared. We have studied the effectiveness of jaw thrust, lingual traction and the application of both manoeuvres simultaneously, in opening up the orolaryngeal airspace in 30 ASA group 1 or 2 patients aged between 16 and 70 yr undergoing elective general surgery requi...
