概括

对于假肢关节感染 (PJI) 的抑制性抗菌疗法 (SAT) 是常见的,但与更高的失败率有关. 这项研究发现,SAT并没有改善结果,这表明需要进行试验来确定可能受益的患者.

科学领域:

整形外科手术整形外科手术
传染性疾病传染性疾病
药理学药理学是指药理学的学科.

背景情况:

假肢关节感染 (PJI) 是关节置换手术后的一个严重并发症.
抑制性抗菌疗法 (SAT) 有时用于慢性或难以治疗的PJIs.
在PJI管理中SAT的长期成果和有效性仍然是研究领域.

研究的目的:

描述抑制性抗微生物疗法 (SAT) 的利用和结果,用于大量前性假肢关节感染 (PJI) 患者队列.
评估接受SAT治疗的患者与不接受SAT治疗的患者的治疗失败率,生活质量和功能关节评分.

主要方法:

一项对720名患有PJI的患者进行前性队列研究.
SAT被定义为持续超过诊断后12个月的抗菌疗法或对SAT的早期意图.
主要结局:24个月"治疗失败" (临床证据,重新手术或死于PJI). 二次结局:简单表格12 (SF-12),牛津部 (OHS) 和膝盖 (OKS) 的分数.

主要成果:

在31.0% (223/720) 的患者中,通常是老年患者,患有并发症,慢性PJI或经过除bridement和植入物保留治疗的患者,处方SAT.
治疗失败在SAT组 (40.1%与19.0%) 中明显更常见,在倾向得分调整后 (aOR 2.48) 仍然与更高的失败率有关.
虽然SAT组的24个月生活质量得分较低,但SAT和非SAT组的功能关节得分与基线的改善类似.

结论:

抑制性抗菌疗法 (SAT) 经常用于假肢关节感染 (PJI) 管理.
在这个队列中,SAT与治疗失败率的增加有关,并且没有证明功能结果有所改善.
需要进一步的研究,包括对照试验,以确定可能受益于PJI的SAT的患者子组.

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...

Healthcare Associated Infections II: Preventive Measures

Essential infection prevention measures are based on the knowledge of the infection chain, the modes of transmission in healthcare settings, and the use of the best practices in all healthcare settings. Compulsory public reporting of healthcare-associated infection rates is needed to allow individuals and the community to make informed choices regarding selecting a healthcare facility.
The best practices for preventing healthcare-associated infections include hand hygiene, patient risk...

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.
Hand washing...
