摘要
目的 :研究肺心病呼吸衰竭患者的血气指标变化对预后的影响。方法 :分析患者血气分析指标的变化与预后的关系。结果 :(1)血气分析指标中的 p H值越低 ,死亡率越高 ;(2 )血气分析指标中的二氧化碳分压越高 ,死亡率也相应升高 ;(3)血气分析指标中的氧分压高低对预后无明显影响 ;(4 )酸中毒总死亡率大于碱中毒 ,三重性酸碱平衡紊乱者死亡率最高。结论 :(1) p H值对预后有绝对影响 ,两者呈负相关系 ;(2 )二氧化碳对预后同样有影响 ,两者呈正相关系 ;(3)同一患者出现二种或以上酸碱平衡紊乱时 ,预后差 ,死亡率高。
Objective:To study the influence of the blood-gas analysis index(BGAI) change on the prognosis of patients with pulmonary heart disease(PHD) complicated respiratory failure.Methods:The relationship between the change of BGAI and prognosis of patients with PHD complicated respiratory failure was analyzed.Results:(1)The lower pH in BGAI was, the higher death rate was;(2)The higher partial pressure of carbon dioxide (PCO 2)in BGAI was,the higher death rate was;(3)Partial pressure of oxygen(PO 2)has no apparent influence to the prognosis;(4)The death rate of acid-poisoning was higher than that in alkali-poisoning, the death rate of three acid-base disturbances was the highest.Conclusion:(1)pH influence prognosis of patients with PHD absolutely and there is negative correlation between them;(2)PCO 2 influence prognosis also,there is positive correlation between them;(3)The prognosis of PHD patients is bad and the death rate is higher when patient have two or more acid-base disturbance.
