颈清术后报道最少的并发症之一为膈神经损伤,膈肌麻痹继发通气功能下降,在合并有肺部疾患的患者中可产生严重呼吸功能损害。本文报告1例右侧颈清术后同侧膈肌麻痹致呼吸衰竭治疗2周后恢复膈肌功能的糖尿病病例,该病例提示,此类重症患者需早期诊断,并进行包括机械通气在内的综合治疗。 One of the least reported complications of neck dissection is phrenic nerve injury, a decrease in secondary ventilatory function following paralysis of the diaphragm, and severe respiratory impairment in patients with pulmonary disorders. This paper reports a case of diabetes mellitus with diaphragmatic muscle function recovered after 2 weeks of treatment of respiratory failure due to ipsilateral diaphragmatic paralysis after right neck dissection. This case suggests that such critically ill patients need early diagnosis and comprehensive treatment including mechanical ventilation .
