概括
在关节置换手术期间,在分界区的手术室空气清洁性更好. 外部区域的人数增加显著增加空气中的微生物,增加手术部位感染风险.
科学领域:
- 与医疗保健相关的感染
- 操作室卫生 操作室卫生
- 空气中的微生物污染.
背景情况:
- 在手术室 (ORs) 中微生物空气污染与手术部位感染 (SSIs) 风险相关.
- 空气清洁标准以每空气体积的殖民地形成单位 (cfu) 定义.
- 单向空气流 (UDAF) 通风系统过空气,创造超清洁区域,减轻员工的空气中的微生物.
研究的目的:
- 在关节更换程序期间,评估划界区内的空气清洁度.
- 确定影响UDAF系统中最佳空气清洁性的局限性.
主要方法:
- 采用活跃空气采样测量cfu的横截面研究设计在一个OR与UDAF.
- 划界区和外围区之间的cfu计数的比较分析.
- 对员工数量,交通和移动模式的观察.
主要成果:
- 在20个关节整形手术过程中采集了166个空气样本.
- 与外部区域相比,在划界区观察到明显较低的cfu计数 (P < 0.001).
- 外部区域的个体数量是较高cfu数量的唯一显著预测因素 (OR:2.566;95%CI:1.306-5.044;P = 0.006).
结论:
- 通过UDAF通风,区分区的空气清洁度高于外界区的空气清洁度.
- 外部区域的人员增加与空气清洁度降低直接相关.

01:25Transmission-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...

01:16Oxygen Delivering System II: Venturi Mask and Transtracheal Oxygen
243
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,...

110
A tracheostomy is a surgical technique that involves making an incision in the neck to provide access to the trachea. It is frequently used in medical conditions such as airway obstruction and prolonged mechanical ventilation. Effective nursing management is crucial for the long-term success of a tracheostomy.

Tracheostomy care is an essential nursing skill that involves cleaning and maintaining a tracheostomy tube to prevent infection and other complications. Here's a step-by-step guide explaining each procedure with its rationale. Note that disposable gloves are to be worn at all times and changed as often as needed to maintain a sterile work environment, and to protect both patient and healthcare worker.

375
Tracheostomy suctioning is a critical procedure healthcare professionals perform to maintain a patent airway in patients with a tracheostomy tube. This procedure is necessary when secretions accumulate in the airway, causing respiratory distress. Here is a step-wise procedural guide for performing tracheostomy suctioning using an open system.
Equipment Required
First, gather all necessary equipment: a sterile suction catheter, a sterile disposable container, sterile gloves, a towel or...
