Abstract

Background and Aims: The objective of this prospective, randomized trial was to compare I-Gel with Supreme LMA in anaesthetized spontaneously breathing patients for short surgical procedures. Material and Methods: Sixty patients of ASAI -ASAII of either gender between 18-60 years undergoing short surgical procedures were randomly assigned to I-gel (Group I) or LMA-Supreme (Group S). After induction with propofol the supraglottic airway device was inserted. We compared the ease and time required for insertion, airway sealing pressure and adverse events related to airway. Results: There were no significant differences in demographic and haemodynamic data. I-gel insertion was easier than LMA Supreme but statistically not significant (p > 0.05) (Chi square test). Numbers of attempts for successful insertions were comparable and in majority device was inserted in first attempt. Although the airway sealing pressure was significantly higher with Group S (25.73+2.21 cm of H2O), the airway sealing pressure of Group I (20.0+2.94 cm of H2O) was very well within normal limit (Student’s t test). There was no evidence of airway trauma, regurgitation and aspiration. Conclusion: I-Gel with acceptable limits airway sealing pressure, easier to insert, less traumatic with lower incidence of sore throat. Hence I-Gel can be a good alternative to LMA-Supreme.
