目的　初步了解我国部分医院急性肺栓塞的诊治情况。方法　 1 997年 8月至 1 999年 7月在全国 2 1家医院开展了“急性肺栓塞尿激酶溶栓 (栓复欣抗凝 )治疗多中心临床试验” ,各医院对试验期间确诊的急性肺栓塞患者填表登记 ,记录其基本情况和诊断、治疗情况。试验结果后收集登记表进行统计分析。结果　 2年间 2 1家医院诊断急性肺栓塞 2 97例 ,溶栓治疗总有效率 80 8% ( 2 3 1 /2 86) ,病死率 9 8% ( 2 8/2 86)。结论　急性肺栓塞是一常见疾病 ,增强诊断意识是减少误、漏诊的关键 ,溶栓治疗是有效的急救措施。 Objective To understand the diagnosis and treatment of acute pulmonary embolism in some hospitals in our country. Methods From August 1997 to July 1999, a multicenter clinical trial of “Acute pulmonary embolism with urokinase thrombolysis (anticoagulant thrombolytic therapy)” was conducted in 21 hospitals across the country from January 997 to July 1999. The hospitals identified the acute Patients with pulmonary embolism fill in registration, record the basic situation and diagnosis, treatment. After the test results collected registration form for statistical analysis. Results Two hundred and seventy-two hospitals diagnosed acute pulmonary embolism in 2 97 cases. The total effective rate of thrombolytic therapy was 80.8% (21 3/286) and the mortality rate was 9.8% (2 8/2 86). Conclusions Acute pulmonary embolism is a common disease. Increasing the awareness of diagnosis is the key to reduce errors and missed diagnosis. Thrombolytic therapy is an effective first aid measure.
