The Value of Bedside Ultrasound in the Diagnosis and Treatment of Pulmonary Embolism in Severe Patients

Abstract

Objective — To explore the diagnostic value of bedside transthoracic echocardiography combined with bedside lower extremity venous ultrasonography in patients with venous thromboembolism. Methods — Select 97 patients with high-risk Caprini scores and high-risk Padua scores from December 2019 to April 2021 in the Second Affiliated Hospital of Shandong First Medical University as the research objects, all of whom completed bedside transthoracic echocardiography combined with bedside lower limbs or upper extremity venous ultrasound examination; compare the results of different ultrasound examinations with spiral CT pulmonary angiography (CTPA); analyze the diagnostic value of bedside transthoracic echocardiography combined with bedside lower extremity venous ultrasound in patients with pulmonary embolism. Results — 97 patients with high-risk Caprini score and high-risk Padua score were confirmed by CTPA in 41 cases of pulmonary embolism; bedside transthoracic echocardiography, bedside lower extremity or upper extremity venous ultrasonography for venous thromboembolism were all positive in 35 cases; among them, 32 cases were confirmed by CTPA as pulmonary embolism, and the diagnostic compliance rate with the gold standard was 87.63%; bedside transthoracic echocardiography combined with bedside lower extremity venous ultrasonography had a diagnostic sensitivity of 78.05% and a diagnostic specificity of 94.64%; Conclusion — Bedside transthoracic echocardiography and bedside lower extremity venous ultrasonography combined for venous thromboembolism can improve the specificity of diagnosis, and it is worthy of popularization and application.
