The numbers were placed in sealed envelopes and by someone other than the procedure Returned and based on that the airway was managed by an anesthesia assistant. 3 Orthopedic patients. Intervention 1: Intervention group: Establishment of airway through endotracheal tube. Intervention 2: Control group: Establishment of airway through laryngeal mask (LMA). Yes - There is a plan to make this available What will be shared: All data can be shared When: After confirming the publication of the article To whom: All Researchers Conditions: Use data to complete clinical trial studies Where to obtain: Dr.Majid Vatankhah through email:m.vatankhah@hums.ac.ir How to obtain: After the investigation of researcher request and presentation of required documents will be accessible.
