Clinical Comparison of I-Gel Supraglottic Airway Device and Cuffed Endotracheal Tube for Pressure-Controlled Ventilation During Routine Surgical Procedures

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.
