In our study, we compared the ventilation performance of i-gel to the endotracheal tube during laparoscopic surgery.~Our patient receive i-gel or endotracheal tube by draw. These patients were Included by the criteria:1.ASA I-II2.Age from 20-80 years old, who were underwent elective GYN laparoscopic surgery and had ability to give inform consent.~The excluding criteria was: 1.presence of any significant lung, heart, brain disease 2. pathology of the neck or upper respiratory tract 3.Potential difficult intubation 4.an increased risk of aspiration, ex:gastroesophageal reflux, full stomach,Obese (BMI>30), and pregnant woman, who were confirmed by patient history and medical chart.~Preoxygenation was maintained for three minutes to avoid bag and mask ventilation. Anesthesia was induced with the routine medication, such as lidocaine、 propofol, fentanyl and cisatracurium. The i-gel or endotracheal tubes were inserted. The lungs were ventilated at the tidal volume (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.
