概括
在治疗其他关节感染后,在未感染的部或膝关节置换器中患上周围假肢关节感染 (PJI) 的风险很低 (在5年内为1-3%). 大多数ipsilateral感染发生在初始PJI治疗后一年以上.
科学领域:
- 整形外科手术 整形外科手术
- 传染病 传染病是一种传染病.
- 关节整形术的结果
背景情况:
- 周围假肢关节感染 (PJI) 可以影响关节整形术 (THA) 或膝关节整形术 (TKA).
- 在对抗关节的治疗后,在未感染的ipsilateral假肢关节中发展PJI的风险尚不清楚.
研究的目的:
- 为了分析患有PJI的风险,在治疗逆侧部或膝盖感染后,在有风险的ipsilateral THA或TKA中分别分析PJI的风险.
- 为了确定这些处于危险的关节中没有PJI的生存率.
主要方法:
- 在205名患者 (123名THA,83名TKA) 的回顾性审查中,在2000年至2019年期间接受了PJI治疗,患有危险的ipsilateral关节.
- 卡普兰-梅尔生存率分析进行,平均随访时间为6年.
- 患者数据包括年龄,性别,BMI和PJI特征 (急性与慢性).
主要成果:
- 没有PJI的5年生存率为97%的风险THA (TKA PJI治疗后) 和99%的风险TKA (THA PJI治疗后).
- 发生了三个新的PJI (2THAs,1TKA),所有这些都是在最初的ipsilateral PJI治疗后一年多.
- 三种新的PJI中有两种是由指数感染的同一个生物体引起的,这表明源控制失败.
结论:
- 在治疗ipsilateral PJI后5年内,在ipsilateral假肢关节中发展PJI的风险很低,范围为1%至3%.
- 侧感染,当它们发生时,通常在初始PJI治疗后一年以上表现出来.
- 在最初的PJI中未能实现源控制是随后的ipsilateral PJI的风险因素.

01:26Factors Affecting the Risk of Infection
The hosts' susceptibility to infection depends on several factors. The integrity of the skin and mucous membranes helps protect the body against microbial attacks. When the skin is altered, the chance of infection, limb loss, and even death increases.
The integrity and count of the white blood cells help the body resist pathogens and fight infection. When impaired, it reduces the body's resistance to pathogens. The acidic pH levels of the gastrointestinal, genitourinary tracts, and skin create...

01:26Healthcare Associated Infections I: Iatrogenic, Exogenic and Endogenic
Healthcare-associated infections (HAIs) occur in a healthcare facility while a person receives care for another ailment. This category also includes work-related infections among healthcare staff.
HAIs significantly increase the cost of health care. Extended stays in healthcare institutions, increased disability, increased costs of medications, including specialized antibiotics, and prolonged recovery times add to the patient's expenses and the healthcare institution and funding bodies. Common...

Infective endocarditis (IE) is a chronic infection of the heart's endocardium, primarily affecting the heart valves. A detailed nursing assessment for a patient with IE involves collecting subjective and objective data to ensure an accurate diagnosis and timely intervention.Subjective DataThe nurse gathers information about the patient's symptoms and complaints during the subjective assessment. Patients with infective endocarditis often report non-specific symptoms that can mimic other...
