血气分析与急性心肌梗塞并发症的关系

Relations Between Blood-gas Analysis and Complications in Acute Myocardial Infarction

为探讨急性心肌梗塞病人病情严重程度与血气分析的关系，对５６例急性心肌梗塞首次发作的病人进行常规血气分析并分析其与室性心律失常及心力衰竭严重程度的关系。结果表明：低氧血症、呼吸性碱中毒并代谢性碱中毒、ｐＨ＜７．３５或ｐＨ＞７．４５的病人有较高的严重室性心律失常及心力衰竭发生率。建议对ＡＭＩ病人应常规进行血气分析，异常时及时给予高流量吸氧。

To probe into the relations between degrees ofseriousness andblood-gas analysis in acute myocardial infarction(AMI).Blood-gas analysis was routinely carried out in 56 cases AMI when they had first attacking.Research was also done on relations between blood-gas analysis and degrees of seriousness of both ventricular arrhythmias and heart failure.Results showed when patients were in hypoxemia,respiratory alkalosis with metabolic acidosis (pH<7.35 or pH>7.45),they would have high incidence of serious ventricular arrhythmias and heart failure.Suggested that AMI patients take blood-gas analysis routinely,andif their blood-gas was abnormal,they should give high flow oxygen inhalation in time.
