Abstract Background This study aims to test and compare Endo tracheal tube and i-gel in terms of their: Efficacy: Difference in the leak fraction between two airway devices before and after pneumoperitoneum with different tidal volumes andcomparison of oro pharyngeal leak pressure. Ease of insertion: Number of attempts required for optimal positioning. Methods Sixty patients, ASA I-II, were randomly selected to the study. Standard anaesthetic technique was used for all patients. The i-gel was then inserted. The lungs were ventilated at three different tidal volumes (6, 8 and 10 ml kg1) using volume controlled ventilation (VCV). The leakvolume was calculated as the difference between the inspired and expired tidal volumes. The leakfraction was also calculated as the leak volume divided by the inspired tidal volume. These observations were recorded with every tidal volume before and after pneumoperitoneum with the i-gel and the conventional tracheal tube Results We found oro pharyngeal leak pressure for i gel as 26cm of H2O and there was no leak in endotracheal tube group even at 40 cm of H2O peak air way pressure. Before and after pneumoperitoneum there was no statistically significant difference in leak fraction or leak volume between i-gel and tracheal tube at tidal volume 6ml kg−1. At 8and 10mlkg−1 there was statistically significant difference between i-gel and tracheal tube both before and after pneumoperitoneum Conclusion In our study we found that i-gel airway can be used safely and effectively during volume controlled ventilation with low and moderate tidal volumes Top Keywords I-gel, Leak fraction, Pneumoperitoneum, Cholecystectomy.
