Effect of Different Head Positions During Endotracheal Intubation on Postoperative Sore Throat

Not Applicable

Completed

• Conditions: Endotracheal Intubation; General Anesthesia
• Interventions: Other: the head in the "sniffing position "

• Registration Number: NCT06059248
• Lead Sponsor: Nanjing First Hospital, Nanjing Medical University

Brief Summary

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.

Detailed Description

Objective: To investigate the effect of tracheal intubation in different head positions on the incidence of pharyngeal pain 1, 6 and 24h after operation;Effect of tracheal intubation in different head positions on the incidence of hoarseness 1, 6 and 24h after operation

Arm && Interventions

Group	Intervention	Description
head elevation position group	the head in the "sniffing position "	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

Primary Outcome Measures

Name	Time	Method
Rate of Participants with postoperative sore throat	1, 6, 24 hours after tracheal catheter removal	Postoperative sore throat is defined as: persistent sore throat with the following grades: 1 point: no sore throat; 2 points: mild, accompanied by odynophagia; 3 points: moderate pain, persistent, worsening with swallowing; 4 points: severe, pain interferes with eating, requires the use of pain medication

Secondary Outcome Measures

Name	Time	Method
Rate of Participants with postoperative hoarseness	1, 6, 24 hours after tracheal catheter removal	Hoarseness is defined as a sound quality different from the preoperative voice and is graded as follows: 1 point: none, no hoarseness; 2 points: slight hoarseness, noticed by the patient; 3 points: moderate hoarseness, pronounced to observer; 4 points: severe hoarseness, loss of voice.
