概括
在门诊干净室 (OCR) 中,移动层状空气流 (LAF) 装置显著降低了在静脉内注射 (IVI) 期间的真菌菌负载. 这种方法实现了与医院手术室相当的微生物水平,提高了IVI安全性.
科学领域:
- 眼科和传染病控制的眼科.
- 微生物学和环境监测
背景情况:
- 静脉内注射 (IVI) 需要无菌的环境来预防眼部感染.
- 门诊干净室 (OCR) 越来越多地用于IVI,但可能缺乏强大的通风.
- 评估不同环境中的微生物负载对于患者安全至关重要.
研究的目的:
- 为了比较IVI专用门诊干净室 (OCR) 和医院手术室 (HOT) 的真菌菌荷载.
- 评估移动层状空气流 (LAF) 装置在OCR中减少微生物污染的有效性.
主要方法:
- 在OCR和HOT环境中,在静脉内注射 (IVI) 过程中进行了一项病例控制研究.
- 使用表面空气系统仪器在多个点 (手术地点,距离现场4米,消毒室) 进行了空气微生物分析.
- 在IVI会议期间,在不同的时间点 (T-1,T0,T1,T2,T3) 进行测量.
主要成果:
- 在使用LAF装置后,OCR中的操作部位显示了微生物负载的显著降低,从T-1的20.33±16.51CFU/m3降低到T0.0的1.00±1.00CFU/m3.
- 相比之下,医院的手术室 (HOT) 持续显示微生物数量非常低,在T0,T2和T3时为0.00±0.00CFU/m3.
- 在OCR中干预后的微生物水平与热环境中的微生物水平相似.
结论:
- 标准化无菌技术与移动LAF设备相结合,在OCR环境中有效减少微生物殖民地.
- 这种方法实现了对IVI手术安全的微生物水平,与医院手术室的微生物水平相当.
- 在OCR中使用移动LAF设备有可能显著提高静脉内注射的安全性.

Transmission-based Precautions II: Airborne and Protective Environment
1.2K
Transmission-based precautions are for patients infected or suspected to be infected (or colonized) with organisms posing a significant risk to others. The transmission precautions include airborne and protective environment precautions.
Airborne precautions:
Use airborne precautions when treating patients known or suspected to have diseases that spread through the air—for example, tuberculosis or measles. These organisms are present in smaller droplets expelled by an infected person and...

Oxygen Delivering System II: Venturi Mask and Transtracheal Oxygen
329
Oxygen therapy is a pivotal aspect of medical care, particularly for patients with respiratory ailments. Two prominent oxygen-delivering systems include the Venturi mask and the transtracheal oxygen catheter.
Venturi Mask
The Venturi mask, named after the Venturi effect, is designed to deliver precise oxygen concentrations. It consists of a large tube with an oxygen inlet that narrows down, causing a pressure drop that pulls air in through adjustable side ports. The mask is a lightweight,...
