SARS患者急性期血气与预后关系的分析

Relationship between acidbase disturbance in blood gas an alysis and prognosis of patients with severe acute respiratory syndrome

目的 :研究严重急性呼吸综合征 (SARS)患者在急性期血气指标的变化对预后的影响。方法 :对我院2 0 0 3年 1— 4月收治的 10 3例 SARS患者中 3 8例在急性期进行血气分析患者第一次血气指标变化与预后的关系进行分析评价。结果 :二氧化碳分压越低、氧分压越低 ,病死率越高 ;p H值的变化对预后无显著影响。同一患者出现两种或两种以上酸碱平衡紊乱时 ,预后差 ,病死率高。结论 :动脉血气分析有助于指导临床治疗和对预后的判断。

Objective: To study the influence of the acute blood gas analysis index change on th e prognosis of patients with severe acute respiratory syndrome(SARS). Methods: Artery blood gas analysis indexes were determined in 38 of 103 cases of SARS pat ients during acute stage, the relationship between the change of blood gas analy sis index and prognosis of patients with SARS was analyzed. Results: The lower partical pressure of carbon dioxide in artery(PaCO 2), partical pres sure of oxygen in artery(PaO 2) in blood was, the higher death rate was. pH in blood had no significant influence on the pr ognosis of SARS patients. The prognosis of SARS patients were worse and the death rate was higher when patient had two or more acidbase disturban ce. Conclusion: The artery blood gas analysis is useful for judging the conditions and progno sis of patients with SARS, and is beneficial for clinical treatment.
