Abstract
Airway assessment without use of muscle relaxant is required in some cases of suspected difficult intubation. A randomized double blind study was carried out on sixty patients of ASA grade I and II, aged between 18-60 years. Anaesthesia was induced with propofol 2.5mgkg-1 after pre-treatment with either lignocaine 1mgkg-1 or normal saline. A scoring system was devised to evaluate the quality of laryngoscopy and was based on degree of jaw relaxation, presence of gag or cough reflex, vocal cord movements and associated limb movements. Pressor response to laryngoscopy was also assessed. Eleven patients (36%) in saline group and twenty seven patients (90%) in the lignocaine group exhibited excellent to good conditions for laryngoscopy. A significant increase in the heart rate was observed only in the saline group. The technique can be of benefit in airway assessment in patients where it is advisable to avoid tachycardia.
