A Study Comparing the Supraglottic Airway Devices and Endotracheal Tube During Controlled Ventilation for Laparoscopic Surgery

In our study, we compared the ventilation performance of i-gel to the endotracheal tube during laparoscopic surgery. The lungs were ventilated at tidal volumes (8mL/kg) using volume controlled. After that, we wanted to observe the respiratory parameters, such as leak fraction, leak volume, tidal volume, peak airway pressure and mean airway pressure. In our hypothesis, the i-gel may be used reasonable alternative to tracheal tube during volume controlled ventilation in laparoscopic surgeries.
