An interventional study of Laryngeal mask airway and Endotracheal tube in Laryngeal Mask Airway, sponsored by Ajou University School of Medicine. Completed at 1 site in Korea, Republic of. Open to participants aged 19 Years to 70 Years. Per ClinicalTrials.gov, last updated 2022-07-20.

In surgery under general anesthesia due to nasal bone fracture, laryngeal mask airway or tracheal intubation has been used. However, it has not been investigated that the difference of recovery profiles according to use of laryngeal mask airway or tracheal intubation in nasal bone fracture surgery. The aim of study is to evaluate the efficacy of the laryngeal mask airway regarding recovery profiles and airway complications, compared to tracheal intubation.

Exclusion Criteria:
Flexible laryngeal mask airway is inserted for general anesthesia
Device: Laryngeal mask airway
Endotracheal intubation was performed for general anesthesia
Device: Endotracheal tube
LMA Flexible is a supraglottic airway device, which can be moved out of the surgical field without displacement of the cuff, or loss of seal for the anesthetist

Endotracheal tube is a plain tube, which is most commonly used in general anesthesia.
