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 oropharyngeal leak pressure. Ease of insertion: Number of attempts required for optimal positioning. Subjects and 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 kg l) using volume controlled ventilation (VCV). The leak volume was calculated as the difference between the inspired and expired tidal volumes. The leak fraction 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 oropharyngeal  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 8 and 10 ml kg−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.
