概括

生物降解定时矩阵 (BTM) 在复杂的伤口中显示了低的感染率. 大多数感染都得到了成功的治疗,BTM损失最小,这表明它在伤口重建方面的有效性.

科学领域:

伤口愈合和组织再生.
生物材料科学是生物材料的科学.
在手术中的传染病.

背景情况:

生物降解定时矩阵 (BTM) 越来越多地用于不可移植的伤床.
有关BTM固有的抗感染性存在担忧,对殖民和感染率的数据有限.
以前的证据主要由病例系列组成,因此感染率和死亡率尚未确定.

研究的目的:

用BTM重建复杂伤口的临床感染率和微生物学概况的评估.
评估BTM在不同类型的伤口中的疗效,并确定与殖民,感染和移植损失有关的结果.
调查BTM前微生物扫描的临床价值.

主要方法:

在Southmead医院接受BTM治疗的22名患者的回顾性病例系列 (2021年10月 - 2023年11月).
分析BTM前的伤口抹布微生物学和随后的临床感染率.
评估BTM救援技术和3个月的整体伤口愈合结果.

主要成果:

76%的BTM前扫描显示微生物生长.
只有14% (3/22) 的患者经历了临床BTM感染.
在66% (2/3) 的感染病例中,成功挽救了BTM,只有5%的BTM部分损失和大多数患者的完全治愈.

结论:

应用前的伤口抹布在预测BTM结果方面可能具有有限的临床价值.
经验性救援技术对于管理临床感染是有效的.
在可控感染风险的复杂伤口重建中,BTM表现出高的成功率.

Infection

Infection

When a pathogen enters the body and reproduces, it can cause an infection, damage body cells, and cause illness symptoms that eventually lead to disease. Therefore, its prevention requires breaking the chain of infection.
The chain begins with pathogens: bacteria, viruses, fungi, prions, or parasites such as protozoa helminths. These can be present on the skin as transient or resident flora, or they can be acquired from the environment. Identifying and treating the type of infection and...

Defense Against Bacterial Pathogens

Defense Against Bacterial Pathogens

The human immune system is a complex network of cells, tissues, and organs that work together to defend the body against bacterial infections. It consists of various immune cells, each playing a specific role in the defense mechanism.
Phagocytes
Phagocytes are the frontline soldiers of the immune system. They include neutrophils and macrophages. Neutrophils are the most abundant type of white blood cell and are quickly mobilized to the site of infection. Macrophages are larger cells that patrol...
