目的评价D-二聚体检测在急诊诊断中的应用价值。方法选择急诊科收治的血管性疾病患者189例和非血管性疾病患者261例,所有患者均进行D-二聚体检测,由2组医师对患者资料(不包括诊断“金标准”)进行分析诊断。观察组患者资料包括D-二聚体水平,常规组不包括D-二聚体水平。比较患者D-二聚体水平、诊断正确率和诊断时间。结果观察组血管性疾病诊断正确率高于常规组,平均拟诊所需时间短于常规组,差异均有统计学意义(P<0.05)。血管性疾病患者D-二聚体平均水平为(7.26±2.04)mg/L高于非血管性疾病患者的(1.42±0.28)mg/L,差异有统计学意义(P<0.05)。结论 D-二聚体检测可提高急诊诊断正确率,缩短诊断时间,在急诊血管性疾病和非血管性疾病的鉴别诊断中具有重要价值。
Objective To evaluate the diagnostic value of D-dimer in emergency diagnosis. Methods A total of 189 patients with vascular diseases and 261 patients with non-vascular diseases were enrolled in the emergency department. D-dimer was detected in all patients. The data of patients (excluding diagnosis, gold standard) Analytical diagnosis. Patient data in the observation group included D-dimer levels, while the conventional group did not include D-dimer levels. D-dimer levels were compared, diagnostic accuracy and diagnostic time. Results The diagnostic accuracy of vascular disease in the observation group was higher than that in the conventional group, and the average time required for the virtual examination was shorter than that in the conventional group (P <0.05). The average level of D-dimer in patients with vascular diseases was (7.26 ± 2.04) mg / L higher than that in non-vascular patients (1.42 ± 0.28) mg / L, the difference was statistically significant (P <0.05). Conclusion D-dimer test can improve the accuracy of emergency diagnosis and shorten the diagnosis time, which is of great value in the differential diagnosis of vascular disease and non-vascular disease.
