概括
接受体外膜氧化 (ECMO) 的儿科患者经历了高率的手术部位感染 (SSI) 和血液感染 (BSI),与更长时间的重症监护室 (ICU) 停留有关. 感染预防策略对于管理这些关键病例至关重要.
科学领域:
- 儿科重症监护医药 儿科重症监护医药
- 传染病流行病学 传染病流行病学
- 支持体外膜氧化 (ECMO) 的支持.
背景情况:
- 体外膜氧化 (ECMO) 是一种拯救生命的疗法,但具有严重并发症的重大风险,包括手术部位感染 (SSI) 和血液感染 (BSI).
- 了解儿科ECMO患者中这些感染的发病率,风险因素和结果对于改善患者管理和结果至关重要.
研究的目的:
- 在接受ECMO的儿科患者中调查SSI和BSI的发病率,危险因素,常见病原体和死亡率.
- 确定与感染发展相关的因素,并评估预防性抗微生物药物的影响.
主要方法:
- 在2012年1月至2022年12月期间接受ECMO的儿科患者 (≤14岁) 进行了一项回顾性队列研究.
- 收集的数据包括患者人口统计,ECMO细节,感染类型 (SSI,BSI),致病原体,ICU停留时间和住院死亡率.
主要成果:
- 这项研究分析了163次ECMO发作,其中22.1%的人患有复合感染 (SSI和/或BSI).
- 确定的主要病原体是SSI的凝聚酶阴性葡萄球菌和Klebsiella pneumoniae,以及BSI的凝聚酶阴性葡萄球菌,大肠杆菌和Candida物种.
- 复合感染与更长的ICU停留时间有显著的关联 (中位数为35天与25天,P=0.032),而预防性抗微生物药物并没有显著降低感染风险 (P=0.265). 住院死亡率为49.1%.
结论:
- 长时间的ICU停留是影响儿童ECMO患者SSI和BSI发病率的一个重要因素.
- 临床医生必须优先考虑强有力的感染预防策略,并保持警,以便在这个脆弱人群中早期发现和管理感染.
- 建议对更大的队列进行进一步研究,以验证这些发现并为临床实践提供信息.

Factors Affecting the Risk of Infection
13.2K
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...

Endoscopic Studies II: Thoracocentesis
1.2K
Thoracentesis(Thoracocentesis), commonly known as pleural tap, is a medical procedure where a 22 gauge needle is inserted into the pleural space, the area between the lung and chest wall. This procedure is commonly performed to diagnose or treat various respiratory disorders.
Description
Excess pleural fluid or air may accumulate in some respiratory disorders in the thoracic cavity. To treat pleural effusion, a physician conducts thoracentesis by carefully piercing the chest wall and entering...

Pulmonary Embolism II: Diagnostic Studies and Interprofessional Care
293
Diagnosing Pulmonary EmbolismDiagnosing pulmonary embolism (PE) involves clinical assessment and advanced imaging tests. The preferred diagnostic tool is the spiral (helical) CT scan or CT angiography (CTA), which uses intravenous contrast media to visualize the pulmonary vasculature and identify emboli.A ventilation-perfusion (V/Q) scan is an alternative for patients unable to receive contrast media. This scan includes both perfusion and ventilation scanning. Perfusion scanning involves...

Healthcare Associated Infections II: Preventive Measures
3.6K
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...

Transmission-based Precautions II: Airborne and Protective Environment
1.8K
Transmission-based precautions are for patients infected or suspected to be infected (or colonized) with organisms posing a significant risk to others. The transmission precautions include airborne and protective environment precautions.
Airborne precautions:
Use airborne precautions when treating patients known or suspected to have diseases that spread through the air—for example, tuberculosis or measles. These organisms are present in smaller droplets expelled by an infected person and...
