Effects on the Awakening With Laryngeal Mask vs Endotracheal Tube in Endoscopic Endonasal Transsphenoidal Base Surgery

"In the Endotracheal group In the ETT group, the procedure will be exactly the same except that the ETT will not be exchanged and the patient will be directly extubated~Hemodynamic variables (blood pressure, HR, CO, rSO2, TCD) will be recorded at 8 moments:~* baseline, in the operating room before anesthetic induction (non invasive arterial pressure)~* end of surgery, before awakening (ETT group) or before ETT replacement (LMA group)~* at 1, 5, 10, 15, 30 and 60 min after extubation or LMA removal (according to group assignment)."

"In the LMA group, after aspirating pharyngeal secretions and with the patient still under general anesthesia, we will insert a Proseal LMA (Laryngeal Mask Co. Ltd., Le Rocher, Victoria, Mahe Seychelles) and extubate the trachea using a guided Bailey technique~Hemodynamic variables (blood pressure, HR, CO, rSO2, TCD) will be recorded at 8 moments:~* baseline, in the operating room before anesthetic induction (non invasive arterial pressure)~* end of surgery, before awakening (ETT group) or before ETT replacement (LMA group)~* at 1, 5, 10, 15, 30 and 60 min after extubation or LMA removal (according to group assignment)."
