肌张力障碍是指主动肌与拮抗肌的收缩不协调或过度持续性收缩所引起的肢体扭曲、重复肌紧张动作或异常姿势为特征的锥体外系疾病。药物治疗无法缓解症状，脑深部电刺激术是治疗肌张力障碍疾病最为有效的治疗方法之一。该类患者因肌张力异常围手术期可能发生气道痉挛、反流误吸等并发症。此例患者为诊断原发性肌张力障碍的15岁青少年，在全身麻醉下行脑深部电刺激术。通过此例患者的麻醉体会讨论该类患者的麻醉管理。“,”Primary dystonia is an extrapyramidal disease characterized by limb distortion, repetitive muscle tension or abnormal posture caused by incoordination of contraction between agonistic muscle and antagonistic muscle or excessive persistent contraction. Drug treatment can not relieve the symptoms. Deep brain stimulation is one of the most effective therapeutic method for treating patients with dystonia refractory to drug therapy. The patients with dystonia may cause abnormal muscle tension such as bronchospasm, gastroesophageal reflux and so on. The patient was an adolescent with primary dystonia who underwent deep brain stimulation under general anesthesia. Looking for the perioperative management of the patients with dystonia by analyzing this case.
