Arm 2
Experimental
No Intervention
The combined topical anesthesia induction group
The routine induction group
The superior glottic mucosa would be anesthetized 3 times with a vaporizer before intravenous anesthesia. After the intravenous induction, a catheter would be inserted to provide the subglottic anesthesia,3-5ml 2% lidocaine would be used for supraglottic anesthesia, and 3ml 1% tetracaine would be used for subglottic anesthesia.
The superior glottic mucosa would be anesthetized 3 times with a vaporizer before intravenous anesthesia. After the intravenous induction, a catheter would be inserted to provide the subglottic anesthesia.In the routine induction group,all procedures will be the same as those of the topical anesthesia group, The drug will be replaced with constant volume saline.
