Abstract：
The ultrasound-guided selective glossopharyngeal nerve block (UGSGNB) has been developed as an approach to overcome the drawbacks of the conventional glossopharyngeal nerve block. The UGSGNB may be performed when a gag reflex occurs during dental treatment. Case 1 involved a 67-year-old man with a medical history of cervical spondylosis and dilated cardiomyopathy. Dental treatment with conscious sedation and the UGSGNB was performed three times. Case 2 involved a 25-year-old woman who was scheduled for dental treatment under general anesthesia because of dental phobia and gagging. Because the patient experienced severe tooth pain and desired urgent treatment, anesthesia was induced with intravenous sedation and the UGSGNB. In both cases, treatments were completed without intraoperative gagging or any complications. Our observations indicate that the UGSGNB can suppress the gag reflex during dental treatment; it may allow surgeons to avoid inducing general anesthesia and deep sedation in patients with a severe gag reflex.
摘要：
超声引导选择性舌咽神经阻滞（UGSGNB）已被开发为克服传统舌咽神经阻滞缺点的方法。UGSGNB可以在牙科治疗期间发生呕吐反射时执行。病例1涉及一名67岁男性，有颈椎病和扩张型心肌病病史。使用清醒镇静和UGSGNB进行三次牙科治疗。案例2涉及一名25岁的妇女，由于牙科恐惧症和呕吐而计划在全身麻醉下进行牙科治疗。由于患者经历了严重的牙齿疼痛并需要紧急治疗，通过静脉镇静和UGSGNB诱导麻醉.在这两种情况下，完成了治疗，没有术中阻塞或任何并发症。我们的观察结果表明，UGSGNB可以在牙科治疗期间抑制呕吐反射；它可以使外科医生避免在严重呕吐反射的患者中引起全身麻醉和深度镇静。
