目的探讨急性肺栓塞及时、准确的诊断方法。方法对 68例肺栓塞患者的临床资料进行回顾性分析。结果血气分析、D-二聚体测定是肺栓塞的初步筛选手段 ,Pa O2 阳性率为 5 8.7% ;Pa CO2 为 5 0 .8% ;D-二聚体为 60 %。 X线胸片非特异性片状阴影出现率为5 4.3 %。心电图特异性改变 (SI、Q 、T )发生率仅 4.4% ,超声心动图所反映右室负荷增加征象 ,肺动脉直径增宽发生率为 77.5 % ;右室扩大 85 .7% ;肺动脉高压 64 .3 % ;V/Q阳性达 10 0 %。结论对以突发呼吸困难、气短等呼吸系症状急诊患者 ,应提高对肺栓塞的警惕 ,按上述程序进行综合检查 ,可及时确诊。
Objective To investigate the timely and accurate diagnosis of acute pulmonary embolism. Methods The clinical data of 68 patients with pulmonary embolism were retrospectively analyzed. Results Blood gas analysis and D-dimer assay were the primary screening methods for pulmonary embolism. The positive rate of Pa O2 was 57.7%, that of PaCO2 was 58.8%, and that of D-dimer was 60%. X-ray non-specific flake shadow appearance rate of 5 4.3%. The incidence of ECG-specific changes (SI, Q, T) was only 4.4%. Echocardiography showed signs of increased right ventricular load. The incidence of pulmonary artery diameter enlargement was 77.5%. Right ventricular enlargement was 85.7%. Pulmonary hypertension. 3%; V / Q positive 10%. Conclusion To patients with sudden respiratory distress, shortness of breath and other respiratory symptoms should be vigilant to improve pulmonary embolism, according to the above procedure for a comprehensive examination, timely diagnosis.
