Summary

This study looked at 60 adults having thyroid surgery to see if the sedative dexmedetomidine or midazolam affects how well doctors can monitor a nerve that controls the voice box. The goal was to find out which drug helps surgeons identify the nerve faster and with better signal quality, which could reduce the risk of voice problems after surgery. Results will help anesthesiologists choose the best sedative for safer thyroid operations.
