To study the advantages of visual laryngeal mask combined with endotracheal intubation in general anesthesia surgery, we compared intubation time, intubation times and intubation success rate of endotracheal intubation through laryngeal mask airway under visual and non-visual conditions, at the same time, the laryngeal mask displacement rate, volume of secretion in airway, the incidence of laryngeal spasm, the incidence and severity of postoperative oropharyngeal pain were also compared between two groups.

In the visual group, a visual laryngeal mask was placed and endotracheal intubation was guided under visual conditions. The endotracheal tube was removed 10 minutes before the end of the operation, and the laryngeal mask was retained.
In the non-visual group, laryngeal mask airway was inserted. After clinical judgment of good counterpoint, endotracheal intubation was inserted blindly through LMA. Endotracheal intubation was removed 10 minutes before the end of the operation, and the laryngeal mask airway was retained.
After anesthesia induction, visual laryngeal mask airway was placed in the visual group and tracheal intubation was guided under visual conditions. In the non-visual group, laryngeal mask airway was inserted, after clinical judgment of good counterpoint of the laryngeal mask, endotracheal intubation was inserted blindly through LMA. Selection of laryngeal mask airway (LMA) model: the ideal body weight of the patient was calculated.
