Should positive end-expiratory pressure be used during elective general anaesthesia with supraglottic airway devices?

Anaesthetists' use of positive end-expiratory pressure during elective general anaesthesia via supraglottic airway devices varies. Positive end-expiratory pressure may help to maintain oxygenation and prevent atelectasis, but could worsen the risk of air leak, gastric insufflation and catastrophic aspiration.

Objective: The aim of this was to compare the Baska® mask and the I-gel® airway in paralyzed patients during general anaesthesia in terms of clinical performance, the risk of aspiration, and intraoperative and postoperative characteristics. Material and Methods: The two devices were compared in 100 paralyzed anesthetized adult patients. Primary outcomes of the study were to evaluate the characteristics of the airway devices within respect to the success of first insertion attempt, the insertion time, the ease of insertion, leak volume, and peak airway pressure. The blood staining on the mask, and the presence of gastric reflux or sore throat two hours postoperatively were evaluated. Hemodynamics, end-tidal CO2 and the peripheral oxygen saturation measurements were secondary outcomes. Results: No statistically significant difference was observed between the groups in the criteria of first attempt success rate, ease of insertion, blood staining upon removal of the masks, gastric regurgitation, or sore throat two hours after the procedure. The insertion time was significantly longer for the Baska® mask compared with the I-gel® airway. The leak volume was significantly higher in the Baska® mask patients throughout the surgical procedure. The heart rate and mean arterial pressure measurements were significantly higher in the Baska® mask patients. Conclusions: Both the Baska® mask and the I-gel ® device can be used effectively for selected paralyzed patients under general anaesthesia. The insertion time was significantly longer for the Baska® mask compared with the I-gel® device.

Background: Supraglottic airway devices (SAD) are becoming increasingly popular for use in patients undergoing laparoscopic surgeries. In this prospective randomised study, we compared three supraglottic airway devices namely, I-gel, Supreme LMA and Ambu Auragain. Aims and Objectives: The study was undertaken to compare three supraglottic airway devices I-gel, Supreme LMA and Ambu Auragain in laparoscopic surgeries under general anaesthesia with controlled ventilation. Materials and Methods: This was a randomized comparative study in which 90 patients undergoing laparoscopic surgeries under general anesthesia were included. In group A Ambu AuraGain was used whereas in group I and Group S I-gel and Supreme LMA was used respectively. Primary outcome measures which were compared amongst the studied groups included time taken for insertion, ease of insertion, attempts required for insertion, ease of insertion of Ryles tube, fiberoptic bronchoscopic grading and Oropharyngeal leak pressure. Results: There was highly significant difference in the time taken for insertion of SAD in Group-A when compared to Group- I (p<0.0001) and Group-S (p<0.0001). Group-A had significantly increased grades of ease of insertion of SAD when compared to Group-I (p=0.04) and Group-S (p=0.004). 16.66% of patients in Group-A required 3 attempts for successful insertion of the SAD, while no patients in Group- I or Group A required more than two attempts for insertion(p<0.05). Conclusion: Ambu AuraGain provides better oropharyngeal seal and has higher leak pressures as compared to I-gel and Supreme LMA with similar hemodynamic stability and post-operative outcome makingit a preferable SAD over I-gel and Supreme LMA.
