Comparative Study of Hemodynamic Changes during the Insertion of Laryngeal Mask Airway and Endotracheal Intubation

Introduction: Airway management is of prime importance during delivery of general anaesthesia. Patients, who have been anaesthetized, are unable to maintain an adequate airway on their own and artificial airway maintenance devices are employed. Aims of the study are to compare classic LMA with endotracheal portex cuffed tube intubation in 60 patients undergoing surgeries under general anesthesia. Methods: This prospective, randomized clinical study was carried over a period of two and half years. 60 patients aged 20-60 years, belonging to ASA grade I-II scheduled for elective surgical procedure were included in this study. Informed written consent was obtained from each patient and the procedure was explained to the patients. All the quantitative data were analyzed using unpaired t-test. The results were expressed, as Mean + SD. ‘P’ value < 0.05 was taken as statistically significant. Results: This prospective randomized clinical study comprised of 60 patients belonging to ASA Grade I – II undergoing elective surgical procedure. 30 patients were studied with Group A (LMA classic) and 30 patients were studied as a Group B (ETT). No. of attempts, ease of insertion, hemodynamics response and other relevant parameters were studied and analyzed. Conclusion: We concluded that LMA classic is safe and useful alternative to endotracheal intubation in elective fasted adult patients undergoing elective surgeries under general anaesthesia. It is judge by stable haemodynamic, adequate oxygenation & ventilation and ease of insertion.
