- Abstract: Objective To investigate the effect of different doses of rocuronium on the monitoring of recurrent laryngeal nerve during endoscopic thyroidectomy.Methods A total of 116 patients undergoing endoscopic thyroidectomy through areolar approach were selected from October 2021 to October 2022,30 males and 86 females,aged 18-64 years,BMI 18.5-30.0 kg/m2,ASA physical status Ⅰ or Ⅱ.All the patients were divided into three groups by random number table method:rocuronium 0.30 mg/kg group(group R1,n=39),rocuronium 0.45 mg/kg group(group R2,n=39),and rocuronium 0.60 mg/kg group(group R3,n=38).After induction of anesthesia,groups R1,R2,and R3 were injected intrave-nously with rocuronium 0.30,0.45,and 0.60 mg/kg,respectively.When the TOF value was 0,the nerve monitoring tracheal catheter was inserted,and the muscle relaxation was monitored throughout the operation.No muscle relaxants were added before the end of the nerve monitoring.The time and amplitude of recurrent laryngeal nerve electromyography(EMG)from intravenous rocuronium to the first occurrence were recorded.The time of intubation and quality of tracheal intubation(Cooper's score),intraoperative special conditions(hypotension,hypertension,bradycardia,tachycardia,intraoperative movement,etc.),postoperative throat pain,hoarseness,and muscle pain were recorded.Results There was no significant difference in the time of first occurrence of recurrent laryngeal nerve EMG among the three groups.Compared with group R1,the recurrent laryngeal nerve EMG amplitude in groups R2 and R3 was significantly decreased for the first occurrence(P＜0.05).Compared with group R1,the time of intubation in groups R2 and R3 was signifi-cantly shortened(P＜0.05).Compared with group R2,the time of intubation in group R3 was significantly shortened(P＜0.05).Compared with group R1,the quality of tracheal intubation in groups R2 and R3 was significantly higher(P＜0.05).Compared with group R1,the incidence of intraoperative and postop-erative laryngeal pain in groups R2 and R3 was significantly lower(P＜0.05).Conclusion During endo-scopic thyroidectomy,compared with rocuronium 0.30 mg/kg,rocuronium 0.45 and 0.60 mg/kg can not only provide good conditions for tracheal intubation,but also monitor recurrent laryngeal nerve signals,and rocuronium 0.60 mg/kg can be intubated for a shorter time.
