Arterial blood gases (ABG) are obtained commonly in dyspneic persons presenting to emergency departments. The study by Burri and colleagues found that the information contained in ABG fails to distinguish between pulmonary and other causes of dyspnea. On the other hand, arterial pH was highly predictive of ICU admission and outcome. Until large clinical studies show equivalence between peripheral venous and ABG, we will continue to advocate the use of ABG in the evaluation of acute dyspnea.
动脉血气分析(ABG)常用于呼吸困难患者就诊急诊科时采集。Burri 等人的研究发现,ABG 中包含的信息无法区分呼吸困难的肺源性和其他病因。另一方面,动脉 pH 值对 ICU 收治和预后具有高度预测性。在大型临床研究显示外周静脉血气与 ABG 等效之前,我们将继续主张在急性呼吸困难的评估中使用 ABG。
