概括

序列组合脱bridement (SCD) 显著降低了 Staphylococcus aureus 周围假肢关节感染模型中的细菌负载. 与BactisureTM相比,这种方法显示出更高的抗生物膜活性,并且与单独的povidone相比,效果相似.

科学领域:

整形外科整形外科整形外科
传染性疾病传染性疾病
手术创新在外科创新.

背景情况:

化学除菌对于治疗周围假肢关节感染 (PJI) 是至关重要的.
最佳的脱bridement解决方案,灌时间和组合缺乏共识.
之前的体外试验研究确定了顺序组合脱bridement (SCD) 作为有效.

研究的目的:

在体内模型中验证顺序组合脱bridement (SCD) 的有效性.
为了将SCD与现有的治疗方法比较,例如Povidone iodine (PI) 和BactisureTM,用于减少PJI中的细菌负载.

主要方法:

使用了为期7天的金黄色葡萄球菌鼠骨PJI模型.
序列组合脱bridement (SCD) 涉及3%的酸,10%的povidone,和5毫米的过氧化.
SCD与10%PI和BactisureTM的单次治疗进行了比较;盐水作为对照.

主要成果:

与BactisureTM (p=0.02) 相比,SCD显著降低了细菌负载 (日志CFU/mL).
SCD显示了比单独PI更大的细菌减少趋势 (p=0.19).
两组之间没有观察到细胞活力或细菌病率的显著差异.

结论:

顺序组合除菌 (SCD) 在体内S. aureus PJI模型中有效降低了细菌负载.
与BactisureTM相比,SCD表现出优越的抗生物膜活性,有效性与PI相比相当.
在PJI中,SCD显示出作为化学脱bridement的标准化,临床适用协议的潜力.

关键词:

生物膜是一种生物膜.化学化解是化学化解的一种方法.鼠类模型模型减少减少减少减少一个连续的组合,连续的组合.

Hand hygiene

Hand hygiene

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.

Combined Effects of Drugs: Synergism

Combined Effects of Drugs: Synergism

Synergism is a useful mechanism where combining two or more drugs is more effective than each constituent used alone. Such combinations are also called supra-additive interactions. The drugs collectively enhance the final therapeutic effect by acting on different targets. Another advantage is that the low dose of each constituent drug is sufficient to achieve the desired effect. This helps reduce the duration of therapy and lower the adverse effects of these drugs.
Such synergistic combinations...

Surface Membrane Barriers

Surface Membrane Barriers

The skin and mucous membranes serve as the primary line of defense against pathogens by providing both physical and chemical protection. These barriers are essential in preventing the entry and establishment of microbes, thereby maintaining the integrity of the host.
The outer layer of the skin, the epidermis, is a robust barrier comprising layers of closely packed keratinized cells. This dense arrangement prevents microbes from penetrating the body. The periodic shedding of epidermal cells...
