目的:回顾性分析动脉血氧分压对急性肺血栓栓塞症(APTE)危险分层及预后的临床价值。方法:选择我院内科2005年3月至2011年10月确诊APTE并行动脉血氧分压测定检查的16例患者,按照血气分析动脉血氧分压数值低于70mmHg分为第1组,大于70mmHg为第2组。比较两组临床特点,高危、中危、低危APTE发生率、右心功能障碍、心源性休克及病死率。结果:第1组高危APTE2例,中危3例;第2组中危3例,低危8例。发生心源性休克、大面积及次大面积肺栓塞、肺动脉高压、右心功能不全有统计学意义。结论:动脉血氧分压可作为APTE者独立的预后指标。
Objective: To retrospectively analyze the clinical value of arterial partial pressure of oxygen in risk stratification and prognosis of acute pulmonary thromboembolism (APTE). Methods: Sixteen patients diagnosed with APTE with concurrent arterial partial pressure of oxygen were selected from Department of Internal Medicine, Department of Internal Medicine, March 2005 to October 2011. According to the blood gas analysis, the value of arterial partial pressure of oxygen was less than 70mmHg and divided into group 1 and 70mmHg For the second group. The clinical features, incidence of high-risk, intermediate-risk and low-risk APTE, right ventricular dysfunction, cardiogenic shock and mortality were compared between the two groups. Results: The first group of high-risk APTE2 cases, 3 cases of moderate risk; the second group of 3 cases of moderate risk, low risk in 8 cases. Occurrence of cardiogenic shock, large and sub-large pulmonary embolism, pulmonary hypertension, right ventricular dysfunction were statistically significant. Conclusion: Arterial partial pressure of oxygen can be used as an independent prognostic indicator of APTE.
