Brief summary
The study was designed to evaluate the success rate, time of insertion, sealing efficacy and security of the Ambu® AuraGain in patients undergoing ambulatory surgery by one anesthetist
Detailed description
Supraglottic devices (SGD), in all their different forms, have become an authentic innovation in airway management especially in day surgery. The Ambu® AuraGainTM (Ambu A/S, Ballerup, Denmark) is a new single-use, anatomically curved supraglottic airway with an integrated gastric access port designed to provide functional separation of the respiratory and digestive tracts allowing the exit of gastric contents and the passage of a gastric tube to manage gastric contents. Its characteristics in the design, composition by a smooth and atraumatic material, the presence of the gastric drainage access, with potential improved patient safety and its characteristic of being disposable, suggests a significant expansion of its use in the coming years. The series in the literature reporting performance or safety of use of the Ambu® AuraGainTM come from studies on selected cases and in certain surgical procedures. However, there are limited studies that have evaluated the efficacy of the device in routine clinical practice in patients intervened in ambulatory surgery and performed by a single investigator.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Evaluate the number of attempts to insert the Ambu® AuraGainTM supraglottic airway | The number of insertion attempts will be collected after anesthesia induction | Insertion attempts (in numbers) From picking up the Ambu® AuraGainTM supraglottic airway until the mask is placed into the patient mouth. (in numbers) |
| Evaluate the time to insert the Ambu® AuraGainTM supraglottic airway | The insertion time will be collected after anesthesia induction after administration of propofol | The time from picking up the Ambu® AuraGainTM supraglottic airway until the cuff was inflated. (in seconds) |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Blood pressure during insertion of the Ambu® AuraGainTM supraglottic airway | At baseline and every 3 minutes until 6 minutes after insertion of the Ambu® AuraGainTM supraglottic airway | Blood pressure in mmHg |
| Heart rate during insertion of the Ambu® AuraGainTM supraglottic airway heart rate | At baseline and every 3 minutes until 6 minutes after insertion of the Ambu® AuraGainTM supraglottic airway] | Heart rate in beep per minute |
| BIS data | At baseline and every 3 minutes until 6 minutes after insertion of the Ambu® AuraGainTM supraglottic airway (To evaluate the evolution of BIS values during insertion of the Ambu® AuraGainTM supraglottic airway | Bis data: number from 100 (awake) to 40-45 (anesthetic status) |
| Oropharyngeal leak pressure of the Ambu® AuraGainTM supraglottic airway. | The Oropharyngeal leak pressure of the Ambu® AuraGainTM supraglottic airway will be collected 10 minutes after the Ambu® AuraGainTM supraglottic airway will be inserted] | The Oropharyngeal leak pressure of the Ambu® AuraGainTM supraglottic airway will be determined with an intracuff pressure of 60 cm H2O by closing the expiratory valve of the breathing circle circuit at a fixed gas flow of 3 L/min and noting the pressure at which an oropharyngeal leak occurs. (in cm H2O) |
