随着内镜室工作时间的增加,气溶颗粒的度显著增加,而微生物水平保持稳定. 这项研究确定了影响污染的关键因素,并提出了减少卫生保健工作者和患者暴露风险的策略.
科学领域:
- 环境健康
- 预防和控制感染
- 职业健康问题
背景情况:
- 内镜套房可能含有空气中的污染物.
- 了解气溶和微生物暴露的时间趋势对于患者和医护人员的安全至关重要.
- 优化感染预防策略需要空气质量动态数据.
研究的目的:
- 在内镜套件工作时间内量化气溶和微生物暴露水平.
- 分析内镜环境中的空气污染趋势.
- 确定影响微生物污染的因素,并提出基于证据的降低风险的建议.
主要方法:
- 使用激光粒子计数器和空气中的细菌采样器测量了气溶颗粒度和微生物负荷.
- 在连续10天内,在基线和工作开始后1,2,3小时进行测量.
- 根据国际和国家标准评估空气质量.
主要成果:
- 与基线相比,气溶颗粒度 (≥0. 5μm) 在工作时间增加了20- 30%.
- 观察到所有颗粒大小的气溶度显著增加,工作时间较长 (p < 0. 01).
- 总微生物殖民地与工作持续时间,多检测,活检频率和手术长度 (p < 0. 05) 有正相关性.
结论:
- 在内镜套件中的气溶污染在工作轮班中逐渐增加.
- 微生物污染与程序因素有关,突出了针对性干预的领域.
- 建议减少内镜诊所卫生工作者和患者的暴露风险.

Bronchoscopy
Description
Bronchoscopy is a procedure that involves direct visualization of the larynx, trachea, and bronchi for diagnostic and therapeutic purposes. A flexible fiber optic or rigid bronchoscope is used to carry out the procedure. The fiber-optic bronchoscope is more frequently used due...
Sputum Studies II: Culture and Sensitivity
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,...
