Ultrasound-Guided Thyroid Cartilage Plane Block vs Ultrasound-Guided Traditional Superior Laryngeal Nerve Block for Awake Fiberoptic Intubation in Patients With Limited Neck Mobility Undergoing Cervical Spine Fixation

Comparison of Ultrasound-Guided Thyroid Cartilage Plane Block and Ultrasound-Guided Traditional Superior Laryngeal Nerve Block for Awake Fiberoptic Intubation in Patients With Limited Neck Mobility Undergoing Cervical Spine Fixation

Important: This information is not medical advice. Talk to your doctor about whether a clinical trial is right for you.

About This Trial

The aim of the work to compare between the effectiveness and safety of ultrasound-guided superior laryngeal nerve block through surface injection of local anesthetic solution on the thyroid cartilage and ultrasound-guided traditional superior laryngeal nerve block on quality of airway anesthesia for awake fiberoptic intubation in patients with limited neck mobility undergoing cervical spine fixation.

Who May Be Eligible (Plain English)

Who May Qualify: - patients aged between 18-65 years - either gender - ASA I-II - limited neck mobility Who Should NOT Join This Trial: - patients who refuse to give consent - non-cooperative patients - have asthma or ischemic heart disease - preoperative hoarseness, sore throat - mental or neurological disorders - contraindications for regional block (coagulopathy , infection at the needle insertion site and allergy to local anesthetics) - body mass index (BMI) \>26 kg/m2. Always talk to your doctor about whether this trial is right for you.

Treatments Being Tested

PROCEDURE

US-guided thyroid cartilage plane block (group TCPB)

Participants in the (group TCPB) will receive US-guided thyroid cartilage plane block. Ultrasound-guided bilateral Thyroid Cartilage Plane Block is performed using the thyroid cartilage plate as an anatomical landmark. 3ml of 2% lidocaine is injected on the surface of the thyroid cartilage plate. Subsequently, perform fiberoptic bronchoscope-guided oropharyngeal, subglottic, and tracheal surface anesthesia. After completing surface anesthesia, perform fiberoptic bronchoscope-guided tracheal intubation, securing it properly.

PROCEDURE

US-guided traditional superior laryngeal nerve block (group traditional SLNB)

Participants in the (group traditional SLNB) will receive US-guided traditional superior laryngeal nerve block. Traditional Superior Laryngeal Nerve Block is performed using the thyrohyoid muscle and thyrohyoid membrane as an anatomical landmark. The thyroid cartilage and the greater horn of hyoid bone are hyperechoic signals on sonography. 3ml of 2% lidocaine is injected above the thyrohyoid membrane next to the superior laryngeal artery between two hyperechoic structures. Subsequently, perform fiberoptic bronchoscope-guided oropharyngeal, subglottic, and tracheal surface anesthesia. After completing surface anesthesia, perform fiberoptic bronchoscope-guided tracheal intubation, securing it properly.
