目的探讨急性肺栓塞的早期临床特征和诊断方法及其相关性。方法对50例急性肺栓塞患者的临床资料进行回顾性分析。结果呼吸困难(68%)、胸痛(36%)、晕厥或黑朦(30%)等为急性肺栓塞最典型的早期表现;动脉血气分析、肺核素检查为重要的确诊手段;初诊确诊率为40%。结论急性肺栓塞早期可无特异性临床表现,但对排除了其他原因的呼吸困难、胸痛等表现后,特别是对有晕厥史者应高度重视,应及早进行肺栓塞的相关检查,提高早期确诊率,以防误诊和漏诊。
Objective To investigate the early clinical features and diagnosis of acute pulmonary embolism and its correlation. Methods The clinical data of 50 patients with acute pulmonary embolism were retrospectively analyzed. Results Dyspnea (68%), chest pain (36%), syncope or amaurosis (30%) were the most typical early signs of acute pulmonary embolism. Arterial blood gas analysis and pulmonary tuberculosis were the most important diagnostic methods. The initial diagnosis rate 40%. Conclusion Early acute pulmonary embolism may have no specific clinical manifestations, but should be attached great importance to dyspnea, chest pain and other symptoms that exclude other causes, especially those who have history of syncope. Early detection of pulmonary embolism should be improved to improve early diagnosis Rate, to prevent misdiagnosis and missed diagnosis.
