Brief Summary:
According to the previous studies, it is reported that the use of sevoflurane in the maintenance of anesthesia may lead to delayed occurrence of positive electromyographic (EMG) signal and lower obtained signal amplitude. In this study, the investigators aimed to investigate the anesthetic effect of sevoflurane combined with dexmedetomidine for neuromonitoring during thyroid surgery. The investigators hypothesize that sevoflurane combined with dexmedetomidine can reduce the movement or spontaneous activity of vocal cords in patients and without affecting the EMG signals.
Detailed Description:
Recurrent laryngeal nerve (RLN) injury is one of the most serious common complications in thyroid operation. Compared with the traditional operation under direct eye vision alone, application of intraoperative neural monitoring (IONM) is able to help surgeon in identifying the RLN during thyroid dissection, and enabling continuous monitoring of the neurological function during operation, thus reducing the incidence of intraoperative RLN injury. Sevoflurane is a common inhaled anesthetic in clinical practice, with the effect of prolonging the action time of muscle relaxants. According to the previous studies, it is reported that the use of sevoflurane in the maintenance of anesthesia may lead to delayed occurrence of positive electromyographic (EMG) signal and lower obtained signal amplitude, which may affect the surgeon's judgment on neurological function during the operation. In this study, the investigators aimed to investigate the anesthetic effect of sevoflurane combined with dexmedetomidine for neuromonitoring during thyroid surgery. The investigators hypothesize that sevoflurane combined with dexmedetomidine can reduce movement or spontaneous activity of vocal cords in patients without affecting the IONM signal.
