对10例单侧声带麻痹患者(患病组)在行甲状软骨成形术(Ⅰ型)前后进行血气分析、气道阻力测定,并与10例正常人(对照组)进行对比分析,以探讨喉源性头晕的发病机理。结果发现,术前,患病组朗读后血液pH值=7. 461,PCO_2=3. 95kPa,较对照组低。气道阻力Raw值=0. 17kPa/(L·S),较对照组稍高。所有患者在朗读后均出现不同程度的头晕、手足麻木等症状。术后,患病组朗读后血液pH值=7. 389,PCO_2=4. 86kPa,Raw值=0. 17kPa/(L·S),与对照组无显著差异。提示喉源性头晕与喉维持血液酸碱平衡的功能有密切的关系。
Blood gas analysis and airway resistance were measured in 10 patients with unilateral vocal cord paralysis (sick group) before and after thyroid cartilage plasty (type Ⅰ), and compared with 10 normal subjects (control group) The pathogenesis of dizziness. The results showed that preoperative and postoperative readings of patients with blood pH = 7.461, PCO_2 = 3.95kPa, lower than the control group. Airway resistance Raw value = 0.17kPa / (L · S), slightly higher than the control group. After reading all patients are varying degrees of dizziness, numbness and other symptoms. After the operation, the pH value of the sick group after reading aloud was 7. 389, PCO 2 = 4.86 kPa, Raw value = 0.17 kPa / (L · S), no significant difference compared with the control group. Tip throat dizziness and throat maintain blood acid-base balance function is closely related.
