RESUMO
Objective:To investigate the application value of bedside lung ultrasound in the diagnosis of acute dyspnea.Methods:Sixty-four patients with acute dyspnea who received treatment in Jincheng General Hospital from January 2020 to January 2021 were included in this study. These patients underwent bedside lung ultrasound, chest X-ray examination, and CT scan. The value of bedside lung ultrasound in the diagnosis of lung consolidation, pleurisy, pleural effusion, and pulmonary edema was analyzed.Results:The diagnostic rate of lung consolidation, pleurisy, pleural effusion, and pulmonary edema by bedside lung ultrasound was 34.4% (22/64), 64.1% (41/64), 67.2% (43/64), and 57.8% (37/64), respectively, which was slightly, but not significantly, different from that by chest CT scans [42.2% (27/64), 57.8% (37/64), 64.1% (41/64), 68.8% (44/64), all P > 0.05]. The diagnostic rate of lung consolidation, pleurisy, pleural effusion, and pulmonary edema by bedside lung ultrasound was significantly higher than that by chest X-ray examination [17.2% (11/64), 26.6% (17/64), 34.4% (22/64), 37.5% (37/64), χ2 = 4.94, 18.16, 13.78, 5.293, all P < 0.05]. Conclusion:Bedside lung ultrasound can help diagnose and screen patients with acute dyspnea quickly, accurately, and timely. Bedside lung ultrasound has a higher rate in the diagnosis of lung consolidation, pleurisy, pleural effusion, and pulmonary edema than chest X-ray examination, which is worthy of clinical application.
