What this trial studies

This study aims to compare the effectiveness and safety of two techniques for administering local anesthesia to the throat during awake fiberoptic intubation in patients with limited neck mobility undergoing cervical spine fixation. One method involves an ultrasound-guided thyroid cartilage plane block, while the other uses a traditional ultrasound-guided superior laryngeal nerve block. The goal is to determine which technique provides better airway anesthesia and patient comfort during the procedure. The study will assess patient satisfaction and the quality of airway anesthesia achieved with each method.

Who should consider this trial

Good fit: Ideal candidates are patients aged 18-65 with limited neck mobility and classified as ASA I-II.

Not a fit: Patients with asthma, ischemic heart disease, or those who are non-cooperative may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could enhance the safety and comfort of patients undergoing awake intubation procedures.

How similar studies have performed: Other studies have explored similar airway management techniques, but this specific comparison is novel.
