OBJECTIVES
Inspiratory activation of the vocal cord adductor, which causes paradoxical vocal cord motion, develops in patients with multiple system atrophy (MSA). To confirm the hypothesis that airway reflexes trigger such paradoxical activation, we investigated the effects of tracheostomy on the adductor activation in a MSA patient.
METHODS
We compared the adductor electromyograms before and after breathing was diverted to a tracheostoma under propofol anesthesia.
RESULTS
The adductor inspiratory activation disappeared during tracheostoma breathing.
CONCLUSION
Airway reflexes as well as MSA-related damage to the respiratory center contribute to the generation of paradoxical adductor activation in MSA patients.
目的
多系统萎缩（MSA）患者会出现声带内收肌吸气激活，这会导致矛盾性声带运动。为了证实气道反射触发这种矛盾性激活的假说，我们研究了气管切开术对一名MSA患者内收肌激活的影响。
方法
我们比较了在丙泊酚麻醉下呼吸改道至气管造口前后的内收肌肌电图。
结果
气管造口呼吸期间内收肌吸气激活消失。
结论
气道反射以及MSA相关的呼吸中枢损伤促成了MSA患者矛盾性内收肌激活的产生。
