概括

微生物殖民在尿导管 (UCs) 中很常见,近一半的隔离物显示多药性耐药性 (MDR). 这凸显了需要在重症监护病房中更好地预防导管相关感染的预防策略.

科学领域:

医学微生物学医学微生物学
传染性疾病传染性疾病
关键护理医学关键护理医学

背景情况:

住院尿导管 (UCs) 经常用于重症监护室 (ICU).
导管相关的尿路感染 (CAUTIs) 是住院患者的一个重大问题.
微生物对UCs的殖民是CAUTIs的前身.

研究的目的:

确定在居住的UC中微生物殖民的流行率.
为了确定UC殖民的患者特异性风险因素.
评估殖民微生物的抗菌素耐药性模式.

主要方法:

一项对61名ICU患者的横截面研究,这些患者内存UCs.
从第二天开始,对UCs进行细菌殖民和敏感性测试.
分析患者的变量,包括年龄,BMI和导管持续时间.

主要成果:

从第二天起,所有内置的UC都显示出殖民 (≥105CFU/mL).
常见的殖民物种包括Pseudomonas aeruginosa,Acinetobacter baumannii,Proteus mirabilis和金黄色葡萄球菌.
47.9%的分离物体表现出多药性耐药性 (MDR).
根据患者年龄,BMI或导管持续时间,在定居过程中没有显著差异.
隔离物和患者实验室变量之间存在弱相关性.

结论:

居住UCs的普遍殖民迅速发生.
在殖民微生物中MDR的高流行率是一个关键问题.
当前的患者特异性因素不能预测殖民风险.
迫切需要加强战略,以预防和管理高风险人群中的CAUTIs.

Healthcare Associated Infections I: Iatrogenic, Exogenic and Endogenic

Healthcare 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.

Factors Affecting the Risk of Infection

Factors 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...

Healthcare Associated Infections II: Preventive Measures

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...

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...

Defense Mechanism Against Infection

Defense Mechanism Against Infection

Natural flora, body system defenses, and inflammation are natural barriers of the body against infectious agents regardless of previous exposure. Normal floras of the human body refer to the microbial population that colonizes the skin and mucous membranes.
In addition, many body organ systems have unique defenses against infection. The skin is an intact, multilayered surface preventing invasion by microorganisms unless impaired. Mucous membranes lining the mouth, nose, and eyelids are barriers...
