About

The goal of this [ randomized clinical trial] is to [effect of different head positions on the incidence of postoperative sore throat ] in [patients with endotracheal intubation ]. The main question it aims to answer is: the rate of postoperative sore throat will be reduced or not with the patients' head position changed during intubation.

Full description

Interventional model: Parallel Assignment

Masking: Double Blind

---

128 participants in 2 patient groups

head sniffing position group

No Intervention group

Description:

The sniffing position group used the conventional method of endotracheal intubation, the operation method was the same as that of the elevation position group, after the anterior part of the tracheal tube was inserted into the glottis, the head was still kept in the backward position, and the tube core was pulled out by another anesthesiologist (the core extubation force was less than 10N), and the endotracheal tube was inserted at the same time.

head elevation position group

Experimental group

Description:

The operation methods of the research group are: left hand laryngoscope, inserted into the laryngeal cavity, fully exposed glottis, right hand tracheal tube from the right corner of the mouth into the mouth, direct vision to insert the anterior part of the endotracheal tube into the glottis, and then the assistant pulls out the tube core (the strength of the extubation core is less than 10N), so that the patient's jaw is adducted, the head remains in the "elevation" position, and the endotracheal tube is inserted at the same time

Treatment:

Other: the head in the "sniffing position "
