Summary

The aim of this clinical trial is to compare the effectiveness and safety of ultrasound-guided thyroid cartilage plane approach with the superior laryngeal nerve space approach for superior laryngeal nerve block in awake tracheal intubation. Patients were randomized into the thyroid cartilage plane block group (T group) or the superior laryngeal nerve space block group (C group). In Group T, bilateral thyroid cartilage plane block was performed under ultrasound with thyroid cartilage as the landmark, and local anesthetic was injected on the surface of the thyroid cartilage. In Group C, local anesthetic was injected into the space between the thyrohyoid membrane and muscle groups above.

We aim to evaluate whether the thyroid cartilage plane approach is not inferior to the superior laryngeal nerve space approach for ultrasound-guided superior laryngeal nerve block in awake tracheal intubation

Conditions

  • Superior Laryngeal Nerve Block

Interventions

PROCEDURE

Ultrasound-guided bilateral Thyroid Cartilage Plane Block

Use a SonoSite high-frequency linear array transducer (5-13 MHz, SonoSite, USA). Placing the transducer parallel to the spine on one side of the neck, ensuring clear visualization of the thyroid cartilage under ultrasound. Using the out-of-plane technique to visualize the needle insertion path and tip. Once the needle tip contacts the cranial half of the thyroid cartilage, injecting 2.5ml of 2% lidocaine on the surface of the thyroid cartilage each side.
