概括
无菌技术缺乏标准化的指导方针,导致手术室外潜在的污染风险. 像非无菌手套这样的简单方法可以减少微生物的传播,但需要更多的研究.
科学领域:
- 医疗保健感染预防和控制.
- 微生物学和污染科学.
背景情况:
- 消毒技术对于预防感染至关重要,但在应用,术语和指导方针方面缺乏全球共识,特别是在手术室之外.
- 在非手术室环境中对无菌技术漏洞的现有研究是有限的,导致对结果的确定性很低.
研究的目的:
- 在手术室外进行的无菌手术期间批判性地审查无菌失效的违规行为.
- 探索各种医疗保健机构当前无菌技术实践的证据基础.
主要方法:
- 对现有文献进行了批判性审查.
- 审查的重点是确定非手术室环境中的无菌失效情况,并评估不同无菌技术方法的证据.
主要成果:
- 一些非无菌材料表现出低污染水平,而无菌手术包装在打开后很快就被污染了.
- 大型或重的包装和特定的打开方法导致了污染;伤口的表面污染是持久的.
- 非无菌的一次性手套可能会减少微生物的传播,但缺乏关于无菌手套污染率的数据.
结论:
- 显著缺乏证据来支持当前的无菌技术实践.
- 非无菌产品可以在功能上无菌,而无菌产品可以迅速受到污染.
- 简单的干预措施,如非无菌手套和非触摸技术,可以大大降低微生物传播风险,这需要进一步的研究.

Tracheostomy Care I: Pre-procedural Steps
1.6K
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.

Hand hygiene
6.4K
Asepsis is the practice of preventing or breaking the chain of infection. The nurse employs aseptic techniques to prevent the spread of microorganisms and reduce the risk of diseases. Hand hygiene is the cornerstone of aseptic techniques and is classified into medical and surgical asepsis. Medical asepsis includes hand hygiene and the use of gloves. Surgical asepsis, or the sterile technique, refers to practices that render and keep objects and areas free of microorganisms.

Asepsis
3.6K
The condition of being free from disease-causing living pathogens is asepsis. Aseptic techniques include a set of standard practices to achieve asepsis. An example is the regular environmental cleaning of all parts of the healthcare facility and hand hygiene at home before preparing or eating food. Medical and surgical asepsis in healthcare practice protects patients from harmful pathogens, minimizes the risk of contamination of susceptible sites, and reduces the risk of infection transmission.

Suctioning the Oropharyngeal Airway
1.2K
In preparing for oropharyngeal airway suctioning, a nurse must gather all necessary equipment, including a suction unit with tubing, a prepackaged suction kit, sterile gloves, water or saline for irrigation, a water-soluble lubricant, and additional personal protective equipment (such as a gown, mask, and goggles) to control infections.
After assembling the equipment, the nurse should practice hand hygiene and don appropriate PPE according to infection control guidelines to avoid the...

Tracheostomy Suctioning II: Procedure
2.5K
Tracheostomy suctioning is a vital nursing procedure that involves removing secretions from the tracheostomy tube to maintain airway patency and prevent respiratory complications. Nurses need to understand the proper technique for tracheostomy suctioning to ensure patient safety and comfort. In this guide, we will outline the step-by-step process for performing tracheostomy suctioning, including preparing the sterile field, donning personal protective equipment (PPE), lubricating and connecting...

Sputum Studies II: Culture and Sensitivity
1.5K
Description
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,...
