A Comparison between The Topical and Intravenous Administration of Lignocaine to Aid The Insertion of Laryngeal Mask Airway

Abstract

Objectives: The cough reflex and laryngeal spasm and cardiovascular hazards were significant after the insertion of laryngeal mask airway. Aim of the study to determine the proper way to aid the insertion of Laryngeal mask airway. Methods: The study was performed between December 2007 and December 2008 in Al jumhori teaching hospital. Results: Cough and laryngeal spasm due to the insertion of LMA (Laryngeal mask airway) were statistically significant in a group A (control group), but cough and laryngeal spasm in a group B (lignocaine I.V.) ,is statistically not significant, and in a group C (the topical lignocaine) showed no cough and no laryngeal spasm. Conclusion: the use of topical lignocaine spray is the best aid for the insertion of LMA.
