结合多部位超声波与培养,可显著降低周围假肢关节感染 (PJI) 病例的诊断不确定性. 这种方法提高了病原体的检测,导致更准确的诊断和及时治疗PJI.
科学领域:
- 整形外科 整形外科 整形外科
- 传染性疾病 传染性疾病
- 诊断微生物学 诊断微生物学
背景情况:
- 准确诊断周围假肢关节感染 (PJI) 是具有挑战性的,特别是在模两可的国际共识会议 (ICM) 2018标准下.
- 现有的诊断方法往往导致PJI病例的不确定性,影响治疗决策.
研究的目的:
- 评估将多站点超声波与标准培养相结合是否可以提高PJI诊断的准确性.
- 评估超声波对手术内培养的阳性和细菌概况的影响.
主要方法:
- 基于ICM 2018标准的四个诊断模型进行了比较,包括具有和没有手术内多位元超声波的模型.
- 分析了375名修复手术患者 (242名PJI,133名无菌松动).
- 评估了不确定的PJI率,培养阳性,细菌光谱和生存曲线.
主要成果:
- 术内多部位超声波将不确定的PJI病例从20.2% (没有组织学的ICM) 和13.6% (标准ICM) 降低到2.9%.
- 超声波增加了突液,组织和假肢的培养阳性率.
- 综合超声波和多站点培养实现了89.7%的阳性检测率.
结论:
- 多站点超声波与培养物相结合,显著提高了PJI的诊断准确性.
- 这种综合方法减少了诊断的不确定性,并改善了病原体的识别.
- 该方法支持更有针对性和及时的PJI治疗策略.

Sputum culture and sensitivity is a medical procedure used to diagnose bacterial infections in the respiratory tract and select the most appropriate antibiotics for treatment. This process involves analyzing sputum samples of thick and opaque secretions produced in the lungs and airways. These samples are collected from patients and then sent to the laboratory for analysis.
The test can identify various pathogens responsible for respiratory infections, including Streptococcus,...
