Abstract
Background: I-gel is usually inserted at room temperature, but in certain studies it was found that I-gel may mould to the laryngeal structures faster if pre-warmed. The present study was conducted to investigate this hypothesis by comparing the airway sealing pressure and leak volume amount between prewarmed I- gel devices and those kept at room temperature in paralysed adult patients on Volume Controlled Ventilation mode of ventilator posted for elective surgeries. Material and Methods: 70 patients were randomly allocated into 2 groups using computer generated randomisation. In Group C, airway was secured with I- gel at room temperature. In Group W, patients airway was secured with I-gel which was prewarmed at 420celcius. Results:The mean insertion time of prewarmed I-gel was 11.94 ±1.59 seconds whereas that of I-gel at room temperature was 14.20 ±1.80 seconds which was stastitically significant. Mean leak volume after one minute and 30 minute of insertion in W group was lesser than C group and the difference was statistically significant (p=0.048).Conclusion: Prewarmed I-gel does not provide a higher sealing pressure or better insertion success rate even in the presence of muscle relaxants. However prewarmed I-gel had smaller insertion time and leak volume than control group.
