The adequacy of i-gel for pressure-controlled ventilation (PCV) in 60 patients undergoing elective surgery was assessed in this study. Patients were randomly assigned to the i-gel group or cuffed tracheal tube group. Several parameters were evaluated such as insertion time, number of attempts, ease of insertion and performance of the cardiovascular system. Furthermore, air leak, leak volume, leak fraction and pharyngolaryngeal (PL) morbidity were also assessed. Findings have shown that i-gel was easier to insert compared to the tracheal tube. Heart rate and mean arterial pressure were higher following tracheal tube but comparable between the two groups after few minutes. Moreover, the leak volume and leak fraction were comparable between the two groups at 15 cm H2O but significantly different at 20 and 25 cm H2O (higher in the i-gel group), and PL morbidity was significantly higher in the tracheal tube. Therefore, the i-gel represents a valuable alternative to the cuffed ETT if pressure is limited to 15 - 20 cm H2O.

Prospective, randomised study on 60 children aged 1-10 years. Insertion attempts and ease, leak pressure and complications were recorded. Results suggest no difference between the devices under these conditions.

Insertion time and successful first attempt incidence were measured within the 50 patients assigned to the device groups. i-gel was quicker to insert with other results 'did not differ'. Authors conclude i-gel may be 'a more advantageous' device compared with LMA.
