- Brief Summary
Title- Comparative evaluation of three supraglottic airway devices: intubating laryngeal mask airway (ILMA), I-gel and Ambu AuraGain for blind tracheal intubation in adults. Background- Although fibreoptic endoscopy is the method of choice for tracheal intubation through a supraglottic airway device (SAD), a fibrescope may not always be available. Hence, there is need to evaluate the SADs for blind tracheal intubation through these. Our study assesses three supraglottic airway devices, intubating laryngeal mask airway (ILMA), i-gel and Ambu AuraGain for blind tracheal intubation in adults Materials and methods- After taking instituitional review board approval, this prospective randomised study was conducted in the department o f anesthesiology, MAMC and associated Lok Nayak Hospital, New Delhi. Ninety adults undergoing elective surgery under general anaesthesia was randomised into three equal groups. After a standardised induction of anesthesia, the group specific SAD was inserted and on achieving adequate ventilation with the device, blind tracheal intubation was attempted. Success rates of blind tracheal intubation through the SADs, ease of device and ET tube insertion and post operative complications (secondary outcome criteria) were evaluated. Data were analysed using SPSS version 17.0 and p<0.05 was considered statistically significant. Results- There was no difference in the incidence of adequate ventilation with any of the SAD. The success rate of tracheal intubation in 1st attempt was 86.67% in ILMA group and 26.67% in i-gel group. The success rate of tracheal intubation was 100% in ILMA group and 40% in i-gel group after both the attempts. It was not possible to intubate through Ambu auraGain in both attempts. Time taken for successful tracheal intubation in ILMA and i-gel did not differ significantly (p value=0.205). Post operative complications also did not differ significantly in the three groups. Conclusion- Out of the three, ILMA is the best device for blind tracheal intubation.
