研究目的: |
以血培养结果为金标准,评估环介导等温扩增联合微流控芯片技术在疑似导管相关血流感染患者中检测金黄色葡萄球菌、表皮葡萄球菌、屎肠球菌、粪肠球菌、大肠杆菌、肺炎克雷伯杆菌、铜绿假单胞菌、鲍曼不动杆菌、阴沟肠杆菌等常见病原菌的诊断效能,探索该检测技术在快速诊断导管相关性血流感染的价值。避免临床中非必要导管拔除,减轻医护人员工作和患者经济负担。 |

|
Objectives of Study: |
Using the blood culture results as the gold standard, the diagnostic efficacy of the loop-mediated isothermal amplification combined with microfluidic chip technology in detecting common pathogenic bacteria such as Staphylococcus aureus, Staphylococcus epidermidis, Enterococcus faecalis, Enterococcus faecium, Escherichia coli, Klebsiella pneumoniae, Pseudomonas aeruginosa, Acinetobacter baumannii, and Enterobacter cloacae in patients with suspected catheter-related bloodstream infections was evaluated. This study aimed to explore the value of this detection technology in the rapid diagnosis of catheter-related bloodstream infections. It also aimed to avoid unnecessary catheter removal in clinical practice, thereby reducing the workload of medical staff and the economic burden on patients. |
