I-gel Laryngeal Mask Airway Combined with Tracheal Intubation Attenuate Systemic Stress Response in Patients Undergoing Posterior Fossa Surgery.

Tang C, Chai X, Kang F, Huang X, Hou T, Tang F, Li J. Mediators Inflamm. 2015;2015:965925

Patients were allocated to either tracheal tube intubation or i-gel facilitated intubation groups, with haemodynamic profile, oxidative response and aneasthesia recovery parameters measured. Using i-gel combined with an endotracheal tube in this scenario proved safe and effective, 'leading to uneventful recovery'.
