OBJECTIVE
To study the influence of the acute blood gas analysis index change on the prognosis of patients with severe acute respiratory syndrome (SARS).
METHODS
Artery blood gas analysis indexes were determined in 38 of 103 cases of SARS patients during acute stage, the relationship between the change of blood gas analysis index and prognosis of patients with SARS was analyzed.
RESULTS
The lower partical pressure of carbon dioxide in artery (PaCO2), partical pressure of oxygen in artery (PaO2) in blood was, the higher death rate was. pH in blood had no significant influence on the prognosis of SARS patients. The prognosis of SARS patients were worse and the death rate was higher when patient had two or more acid-base disturbance.
CONCLUSION
The artery blood gas analysis is useful for judging the conditions and prognosis of patients with SARS, and is beneficial for clinical treatment.
目的
探讨急性血气分析指标变化对严重急性呼吸综合征（SARS）患者预后的影响。
方法
对103例SARS患者中的38例在急性期进行动脉血气分析指标测定，分析血气分析指标变化与SARS患者预后的关系。
结果
动脉血二氧化碳分压（PaCO2）、动脉血氧分压（PaO2）越低，死亡率越高。血液pH值对SARS患者预后无显著影响。SARS患者出现两种或以上酸碱紊乱时，预后较差，死亡率较高。
结论
动脉血气分析有助于判断SARS患者病情及预后，有利于临床治疗。
