ABSTRACT

BACKGROUND

The aim of this study is to compare the I-Gel and Classic LMA (CLMA) in elective surgeries with regard to ease and success rate of insertion, time of insertion, airway sealing pressure and associated complication.

MATERIALS AND METHODS

In a prospective randomised study, 60 adult patients of ASA I-II of either gender between 18 and 60 years presenting for a short surgical procedure under general anaesthesia using either I-Gel or CLMA. An experienced anaesthesiologist inserted appropriate sized I-Gel or CLMA in patients using standard insertion technique and assessed the intraoperative findings of the study regarding time taken for respective device insertion, effective seal and complications were done.

RESULTS

There were no significant differences in demographic and haemodynamic data. Ease of insertion and success rate were comparable. No significant difference in both devices (P > 0.05) (Chi-square test). The mean time for insertion was more with CLMA (25.623±5.28 sec) than with I-Gel (16.80±3.336 sec) (P < 0.05). Although, the airway sealing pressure was significantly higher with I-Gel (26.07±3.073 cm of H₂O), the airway sealing pressure of CLMA (19.70±2.10 cm of H₂O) was very well within normal limit (Student’s ‘t’ test). Incidence of complications were comparable.

CONCLUSION

I-Gel is a supraglottic device with acceptable airway sealing pressure, easier to insert and less sore throat incidence. Hence, I-Gel can be a good alternative to CLMA.
