Reporting Groups
  Description
Disposable Laryngeal Tube Suction (LTS-D) Patients were randomly distributed into this group. The patients assigned to this group were intubated using a new LMA device the LTS-D.
Esophageal Tracheal Combitube(ETC) Patients were randomly assigned into this group. The patients assisgned to this group were intubated with the device ETC.
ProSeal Laryngeal Mask Airway (PLMA) Patients were randomly assigned into this group. The patients in this group were intubated with the device PLMA.
