Objective: Since the inception of Bailey manoeuvre, various authors have advocated for the substitution of endotracheal tube (ETT) with a supraglottic airway device (SAD) before the emergence from anaesthesia. There is scant information about the ideal supraglottic device in the literature. The present study compared the Proseal laryngeal mask airway (LMA) with the I-gel SAD during the Bailey manoeuvre. The primary objective was to compare these for ease of insertion and adequate placement of supraglottic airway, whereas the secondary objective was comparison of haemodynamics following the Bailey manoeuvre.
Methods: A total of 100 patients aged 18-60 years who were scheduled for elective surgery under general anaesthesia were randomised into 2 groups: group I (Bailey manoeuvre using Proseal LMA) and group II (Bailey manoeuvre using I-gel). The Bailey manoeuvre was performed 15 min before the end of surgery using the chosen supraglottic airway as per randomisation. We measured the ease of insertion (number of attempts required for insertion) and adequate placement (Brimacombe scoring) of SADs (fibre-optic bronchoscopy). Haemodynamic parameters were recorded until 10 min after the Bailey manoeuvre.
Results: The groups were comparable in terms of demographic parameters. Both the devices were comparable in terms of ease of insertion (p>0.05). Significantly higher (p<0.05) Brimacombe scores were seen with the I-gel. Significant (p<0.05) rise in systolic blood pressure, diastolic blood pressure, and mean arterial pressure was observed at the insertion of SAD, removal of ETT, and at 1 min after the Bailey manoeuvre in Proseal LMA in contrast to the I-gel.
Conclusion: This study showed that the I-gel provides a better glottic visualisation and haemodynamically superior profile compared with the Proseal LMA during the Bailey manoeuvre.
