Abstract
PURPOSE
The main objective of this study was to evaluate the performance of the Ambu™ AuraGain™ device by determining its main parameters of use and complications.
METHODS
A total of 250 adult ASA physical status i to iii patients from five hospitals in Spain who received general anaesthesia with a supraglottic airway (SGA) device were enrolled in this study.
RESULTS
The primary outcome was analysed for 244 patients and a median OLP of 32 cm H2O (IQR 28-36 cm H2O) was obtained. Insertion was achieved at first attempt in 85% of cases, and overall in 98% of cases, in a median time of 15 s (12-22.5). We applied manoeuvres in 61% of patients to facilitate the process. Ventilation was effective in 97.2% of the interventions (95% CI 0.99-0.94) throughout the procedure. Insertion of the gastric tube was easily performed in 99.6% of the patients, and the vocal cords were viewed by fibrobronchoscopy in 96.3% of cases. Logistic regression analysis identified the use of sizes smaller than those recommended as a risk factor for low OLP (< 25 cm H2O). The main complication recorded was the presence of blood when withdrawing the SGA device (15%).
CONCLUSIONS
Our results confirm that the use of AuraGain allows airway management in a reliable and effective way achieving high OLP and low incidence of associated complications, establishing it as a useful alternative in the routine clinical setting of anaesthesiologists. AuraGain performance was consistent in all five centres.
