Thyroid and parathyroid surgery is associated with a 1 to 6 percent incidence of injury to the recurrent laryngeal nerve. Electrical stimulation of the recurrent laryngeal nerve produces vocal cord motion that can be monitored by means of a double-cuffed endotracheal tube. Twelve patients underwent prospective evaluation with this monitoring system, and in all 12, the recurrent laryngeal nerve was accurately identified and localized. The nerve could be stimulated from a mean distance of 1.7 cm by a mean amperage of 1.3 mA. Postoperative indirect laryngoscopy demonstrated normal vocal cord function in all patients.
甲状腺和甲状旁腺手术导致喉返神经损伤的发生率为1%至6%。对喉返神经进行电刺激可产生声带运动，这可以通过双套囊气管内导管进行监测。12例患者使用该监测系统进行了前瞻性评估，在所有12例患者中，喉返神经均被准确识别和定位。通过平均1.3毫安的电流，可从平均1.7厘米的距离刺激该神经。术后间接喉镜检查显示所有患者的声带功能均正常。
