Laryngeal Mask Airway Facilitates a Safe and Smooth Emergence From Anesthesia in Patients Undergoing Craniotomy

Laryngeal Mask Airway Facilitates a Safe and Smooth Emergence From Anesthesia in Patients Undergoing Craniotomy: A Prospective Randomized Controlled Study

Stabilizing hemodynamic and reducing pulmonary complications during extubation with switching endotracheal tube to laryngeal mask in craniotomies

recruit ASA: 1-3, 20-65 years old undergoing neurosurgery under general anesthesia Excluded 1.Decline to participated 2.Difficult airway 3.Body Mass Index >30 4. Pregnant woman 5.Nothing Per Os <8hrs(case number:80).

General anesthesia Induction: 0.15-0.2 mg/kg cisatracurium or 0.6-1.2mg rocuronium , 1.5-2 mg/kg propofol, 1-2 mcg/kg Fentanyl. Endotracheal tube 6.5-7.5mm. Maintenance with sevoflurane 2- 3% FiO2:100%. Optimal muscle tension monitor. When surgery done, sevoflurane at 2.63-2.97%

Then randomly assigned two group Anesthesia group(control group) : Removed endotracheal tube at sevoflurane at 2-3% Switching group (intervention group): Intervention with endotracheal tube to laryngeal mask, and removing laryngeal mask at sevoflurane: 0.4MAC
