Fibrodysplasia ossificans progressiva is an autosomal dominant condition that causes cervical spine fusion and ankylosis of the temporomandibular joint, resulting in anaesthetic challenges. Awake tracheal intubation with flexible bronchoscopy is recommended for general anaesthetics required by patients with this disease. This case report describes the novel approach of using dexmedetomidine sedation in combination with local anaesthesia to allow dental extraction of the fifth and seventh upper left teeth in a patient with fibrodyplasia ossificans progressive, who had a known difficult airway and profound thrombocytopenia. This procedure was not previously tolerated by the patient under local anaesthesia alone. The use of dexmedetomidine was successful in facilitating completion of the procedure with a high degree of patient satisfaction. We discuss the advantages of dexmedetomidine over other sedative agents due to its minimal effects on respiratory drive and airway muscle tone. We highlight the use of dexmedetomidine for complex cases such as this, where tracheal intubation is potentially challenging, but the procedure itself could be managed under sedation and local anaesthesia.
进行性骨化性纤维发育不良是一种常染色体显性疾病,可导致颈椎融合和颞下颌关节强直,从而带来麻醉挑战。对于患有这种疾病的患者所需的全身麻醉,建议采用清醒状态下经柔性支气管镜气管插管。本病例报告描述了一种新方法,即使用右美托咪定镇静联合局部麻醉,为一名患有进行性骨化性纤维发育不良、已知气道困难且严重血小板减少的患者拔除左上第五和第七颗牙齿。该患者以前单独使用局部麻醉无法耐受此操作。右美托咪定的使用成功地促进了手术的完成,患者满意度很高。我们讨论了右美托咪定相对于其他镇静剂的优势,因为它对呼吸驱动力和气道肌张力的影响最小。我们强调了右美托咪定在这类复杂病例中的应用,在这类病例中气管插管可能具有挑战性,但手术本身可以在镇静和局部麻醉下进行。
