目的 :评价心血管术后床旁胸片的临床应用价值及限度。方法 :2 0 6例心血管术后病人 ,使用移动 X线机摄取床旁胸片 ,分析术后新出现的异常。结果 :上述床旁胸片新出现异常率高达 6 0 .7% (12 5 / 2 0 6 ) ,左侧居多占 35 .4% (73/ 2 0 6 )。其中最常见的依次为胸腔积液、肺不张和气胸 ,发生率分别为 36 .4%、2 7.7%和 9.2 %。结论 :床旁胸片是全面了解心血管术后病人胸肺异常的重要和有效的检查手段 ,但有一定限度 Objective: To evaluate the clinical value and limit of bedside chest radiograph after cardiovascular surgery. Methods: Twenty-six patients undergoing cardiovascular surgery underwent bedside chest radiography with a mobile X-ray machine to analyze emerging abnormalities. Results: The abnormal rates of bedside chest radiographs were as high as 60.7% (125/206), while those on the left side were mostly 35.4% (73/206). The most common of these were pleural effusion, atelectasis and pneumothorax, with rates of 36.4%, 7.7% and 9.2%, respectively. Conclusion: The bedside chest radiography is an important and effective method for comprehensive examination of chest and lung abnormalities in patients with cardiovascular diseases, but there are some limits
