An Observational Study to Compare Ambu Auragain and Supreme Laryngeal Mask Airway for Controlled Ventillation Under Anaesthesia
Journal Title: Indian Journal of Anesthesia and Analgesia - Year 2019, Vol 6, Issue 2
Abstract
Context: Not many studies have compared the new laryngeal mask airway (LMA) devices with pre-existing ones. We compared ambu auragain LMA with LMA supreme in this study for controlled ventilation under general anaesthesia. Aims: The main aim of this study was to the compare ambu auragain LMA with the LMA supreme for controlled ventilation during general anaesthesia. Material and Methods: 50 patients aged 18 to 50 years of American society of Anaesthesiologists (ASA) grade I and II of either gender, weight 30 to 70 kilogram, with Mallampatti grade -I/II posted for elective surgeries in supine position under general anaesthesia were randomly allocated into two equal groups. Group A (ambu auragain) and group S (LMA supreme). Both groups were compared for numbers of attempts and time taken for insertion of device, ease of insertion of nasogastric tube (NGT), oropharyngeal leak pressure, hemodynamic stability and any side effects or complications. Statistical analysis: The statistical analysis was assessed by unpaired student’s t-test. p<0.05 was considered significant. Result: Both groups were statistically comparable in regard to number of attempts for placement and time of insertion of device, ease of insertion of NGT and haemodynamic stability. Group A had higher oropharyngeal leak pressure 32.0 ± 1.34 compared to Group S 26.0 ± 1.21 (p=0.0001). Conclusion: Ambu auragain can be a better alternative to LMA supreme for controlled ventilation under general anaesthesia due to high oropharyngeal leak pressure.
