Adequate Dosage of Sugammadex on Thyroid Surgery

Comparison of Sugammadex Dosages to Reverse the Effect of Rocuronium for Continuous Intraoperative Neuromonitoring in Thyroid Surgery

This study was designed to compare two dosage of sugammadex after tracheal intubation for optimal condition of continuous intraoperative neuromonitoring in thyroid surgery to protect recurrent laryngeal nerve.

Vocal cord paralysis is not a rare complication in thyroid surgery. Nerve monitoring technique has been developed, and many clinicians use the technique for saving the concerned nerves. Many studies showed that the effect of sugammadex on reverse of neuromuscular blocking after tracheal intubation. However, optimal dosage was not founded for sugammadex. This randomized controlled trial is to compare 1 mg/kg and 2 mg/kg as dosage of sugammadex for optimal continuous intraoperative neuromonitoring in thyroid surgery to prevent vocal cord paralysis.

For '1 mg/kg' group, sugammadex of 1 mg/kg (ex. 60 mg for 60 kg patient) will be administered to the assigned patient for this group after tracheal intubation. We will use Sugammadex 200 MG in 2 ML Injection for this.

For '2 mg/kg' group, sugammadex of 2 mg/kg (ex. 120 mg for 60 kg patient) will be administered to the assigned patient for this group after tracheal intubation. We will use Sugammadex 200 MG in 2 ML Injection for this.

1 mg/kg or 2 mg/kg intravenous injection for each group (1 mg/kg group, 2 mg/kg group) after tracheal intubation

During operation, surgeon evaluate the quality of signal of neuromonitoring on the basis of NIM III device.
