RESUMEN
PURPOSE: The purpose of this study was to examine the utility of the Aintree Intubation Catheter (AIC) with three types of supraglottic airway devices for tracheal intubation (ISGAs) using a manikin. METHODS: Participants were 21 anesthesiologists with more than 2 years of experience in clinical anesthesia. Three types of ISGAs were passed through the glottis: Fastrack-Single Use (FSU; size 4), air-Q (size 3.5), and i-gel (size 4). Participants attempted fiberoptic tracheal intubation with the ISGAs in random order. Success rate of tracheal intubation, intubation time, and collision with the glottis were recorded. Participants also evaluated the subjective difficulty of the entire intubation process and passing the tracheal tube through the glottis using a Visual Analogue Scale. RESULTS: The FSU required a significantly longer time for intubation compared with the other two ISGAs (p < 0.05). AIC use did not significantly improve the success rate of intubation or shorten intubation times for any of the ISGAs. However, there were significantly more collisions with the glottis without AIC use for the FSU and air-Q compared to when they were used with the AIC (FSU, p = 0.015; air-Q, p = 0.025). CONCLUSION: Among the ISGAs tested, intubation took longer with the FSU, and the FSU had a higher failure rate than the other ISGAs. AIC significantly decreased the number of collisions with the FSU and air-Q. These findings suggest that the AIC is effective in reducing collisions with the tracheal tube and thus will reduce the risk of mechanical injury to the airway.

We present a case of an 18-year-old male who underwent strabismus operation under general anesthesia. In his childhood, tracheostomy had been performed for the repair of cleft lip and palate. His Mallampati classification was IV and preoperative endoscopic examination revealed megaloglossia and severe airway narrowing. For possible difficult airway, intubating laryngeal airway (air-Q®, size 2.5) was used for tracheal intubation. Following insertion of air-Q®, trachea was intubated via air-Q® guided with fiberscope. The patient was ventilated via tracheal tube with the air-Q® remaining in place during the operation. air-Q® can be effectively utilized for airway management for an adult Apert syndrome patient
