Abstract
Introduction: Airway management is one of the most important skills in the field of anesthesiology and inability to secure the airway can lead to catastrophic results. Before 1990, only the face mask and the endotracheal tube (ETT) were the available airway devices. Since then several supraglottic airway devices have been developed, of which the laryngeal mask airway (LMA) is the most popular one. Materials and Methods: The study was conducted at Kamineni Institute of Medical Sciences, Narketpally, Nalgonda (Dist), A.P, during the period of October 2011 to September 2013. A prospective randomized double blind study was conducted on 80 patients of ASA I and II between the age group of 18-60 years undergoing various elective minor surgical procedures i.e breast abscess, fibroadenoma of breast, cervical lymphnode excision biopsy, Incisional biopsy of axillary lymphnode, collies reduction, under general anaesthesia. Patients were randomly divided into two groups of 40 each. Group A – Propofol group, Group B – Thiopentone with local anaesthetic spray group. Results: Excellent insertion score was observed in 35(87.5%) and 34(85%) patients in group A and group B respectively. Insertion score was satisfactory in 5(12.5%) patients of group A and 6(15%) patients of group B. None of the patients had poor insertion score in both the groups. The groups were statistically insignificant. Conclusion: In conclusion, we have shown that if 30 mg of topical lignocaine is sprayed onto the posterior pharyngeal wall 3 minutes before induction of anaesthesia with thiopentone, the conditions for insertion of an LMA are equal to those following an equipotent dose of propofol, but with greater haemodynamic stability and significantly less respiratory depression.
