Postoperative Sore Throat
Conditions
Brief summary
investigate the effectiveness and safety of ultrasound-guided bilateral internal branch of the SLN (iSLN) block for alleviating POST immediately after the operation.
Interventions
1.5 ml will be injected
PROCEDUREinternal superior laryngeal nerve block
A linear 4- to 12-MHz ultrasound probe will be placed in the oblique parasagittal plane to obtain an image of the hyoid bone and the thyroid cartilage. The probe will be kept parasagitally, and the following structures will be identified anteriorly to posteriorly: omohyoid muscle, sternohyoid muscle, thyrohyoid muscle, thyrohyoid membrane, superior laryngeal artery, and pre-epiglottis space. After identifying the local anatomic structure, a needle will be inserted out-plane from anterior to posterior. The muscles above the thyrohyoid membrane will be penetrated and hydrodissected; local anesthetic will be injected into the superior laryngeal nerve space. The superior laryngeal nerve space will be located between the hyoid bone (cephalad) and the thyroid cartilage (caudal) and delimited between the thyrohyoid muscle, anteriorly, and the thyrohyoid membrane and the pre-epiglottis space, posteriorly
0.5 ml will be injected
