使用三种方法测量干净的手术室中的动态空气质量:一项前性研究
The Journal of hospital infection
|December 5, 2025
概括
手术室 (OR) 的空气质量在手术期间波动很大,在伤口关闭期间微生物污染达到峰值,在手术中期颗粒数量上升. 动态监测和减少门口的开放对于预防手术部位感染至关重要.
科学领域:
- 与医疗保健相关的感染
- 在医疗保健机构的环境卫生.
- 外科手术的安全性
背景情况:
- 手术室 (OR) 是关键环境,空气质量直接影响手术部位感染 (SSI) 率.
- 在手术室保持最佳空气质量对于患者安全和感染控制至关重要.
研究的目的:
- 描述手术过程中手术室内空气污染的动态.
- 为了确定特定的手术期间阶段和与高污染水平相关的风险因素.
- 评估当前空气质量标准在反映实时手术风险方面的有效性.
主要方法:
- 在三个ISO第7类胃肠道 (GI) OR中进行了前性观察研究.
- 在四个手术内阶段 (T1-T4) 测量了空气中的细菌,沉积细菌和颗粒数量.
- 同时记录人员数量和门打开频率,以与空气质量参数相关联.
主要成果:
- 在整个手术阶段观察到空气质量参数的显著时间变化 (P < 0.001).
- 微生物污染 (空气传播和沉细菌) 在伤口关闭期间显著达到峰值 (T4).
- 颗粒物计数在手术中期 (T3) 最高,与增加的活动和门口开放相关.
结论:
- 手术室的空气质量非常动态,在特定的手术阶段会出现明显的污染峰值.
- 当前的静态空气质量标准可能无法充分解决手术期间的污染风险.
- 建议实时动态监控和严格的协议,以尽量减少门的打开是有效的SSI预防.

Respiratory Depth
Respiratory depth measures the volume of air inhaled or exhaled during a breath. It can vary from shallow to deep and typically remains consistent when a person is at rest or asleep. Occasionally, individuals will automatically inhale deeply, known as sighing, which inflates the lungs with more air than normal breathing.
To assess respiratory depth, observe the degree of chest excursion or movement:

Assessment of Ventilation
A Ventilation assessment is critical for monitoring a patient's health status. Respiration, one of the most accessible vital signs, provides insights into the function of numerous body systems and can indicate serious health issues, such as brainstem injuries from head trauma.
