A comparative study of laryngeal mask airway and cuffed Endo-tracheal tube in different surgical procedures

Abstract

Introduction: Endotracheal intubation is frequently an essential procedure in general anaesthesia. Endotracheal intubation is the trans laryngeal placement of endotracheal tube into the trachea via nose (nasotracheal intubation) or mouth (Oro-tracheal intubation). Material and Methods: A comparative study of Laryngeal Mask Airway and Cuffed endotracheal Tube in different Surgical Procedures” was carried at Department of Anaesthesiology in a Tertiary care teaching hospital from October 2018 to October 2019 on patients of both sexes, in age group of 20-50 years of ASA grade I and Grade II posted for different surgical procedures under general anaesthesia over a period of 6 months with due permission from the hospital ethices committee and after obtaining informed consent of patients. Result: All patients were within the weight range of 36 to 80 kg. Demographically patients in both the study groups were almost identical with respect to age, weight and sex ratio. Tests of significance were carried out by student t-test or modified t-test. And p value < 0.05 is considered statistically significant and marked as *. Post induction fall of pulse rates in both groups did not show much difference. There is more rise in mean pulse rate in group I than in group II in comparison to post induction value at zero, one and three min. Conclusion: Thus it may be concluded that use of laryngeal mask airway offers more favorable haemodynamic stability as compared to endo-tracheal intubation with less post operative complications being minimally invasive to the airway it is associated with less post operative complication and may be considered as an important adjunct in the armamentarium of the anaesthesiologists for safe general anaesthesia.
