目的:探讨肺栓塞患者的危险因素、临床表现及实验室检查,提高临床对肺栓塞的认识。方法:收集本院2006年1月至2009年2月住院期间确诊为肺栓塞的110名患者的一般资料、危险因素、临床表现、相关检查等数据,对所统计的数字进行SPSS13.0分析。结果:呼吸困难组74例(67.3%),无呼吸困难组(32.7%),两组比较危险因素无统计学差异,比较发现氧分压、二氧化碳分压、肺动脉内径无差异,但是右心室内径检查显示两组具有明显的差异。结论:1.不可过分依赖“三联征”诊断肺栓塞,以免误诊、漏诊。2.危险因素:外伤、手术、制动、深静脉血栓,慢性支气管炎,高血压对呼吸困难组与非呼吸困难组中的肺栓塞形成无统计学差异。3.肺栓塞患者呼吸困难与心功能不全具有明显相关性,呼吸困难组应住监护病房,密切观察病情变化。
Objective: To explore the risk factors, clinical manifestations and laboratory tests in patients with pulmonary embolism to improve the clinical understanding of pulmonary embolism. Methods: The data of 110 patients diagnosed as pulmonary embolism from January 2006 to February 2009 in our hospital were collected. The data, risk factors, clinical manifestations and related examinations were collected. SPSS 13.0 was used to analyze the statistics. Results: There were 74 cases (67.3%) with dyspnea group and 32.7% without dyspnea group. There was no significant difference between the two groups in the risk factors. Compared with the control group, there were no differences in oxygen partial pressure, carbon dioxide partial pressure and pulmonary artery diameter, Examination revealed significant differences between the two groups. Conclusion: 1. Do not over-rely on “triple sign ” diagnosis of pulmonary embolism, so as to avoid misdiagnosis, missed diagnosis. 2. Risk factors: trauma, surgery, braking, deep venous thrombosis, chronic bronchitis, hypertension in dyspnea group and non-dyspnea group pulmonary embolism was not statistically different. 3. Dyspnea in patients with pulmonary embolism and cardiac dysfunction have significant correlation, respiratory distress group should live in intensive care unit, close observation of changes in condition.
