概括
在新生儿中,与死性肠球炎 (NEC) 相关的血流感染 (BSI) 与低出生体重 (BW) 和高白细胞 (WBC) 数量有关. 这些发现有助于优化受影响新生儿的治疗策略.
科学领域:
- 新生儿科学 新生儿科学
- 传染性疾病 传染性疾病
- 临界护理医学 临界护理医学
背景情况:
- 结核性肠球炎 (NEC) 是新生儿严重的胃肠道疾病.
- 血流感染 (BSI) 是NEC的一个重要并发症,增加了发病率和死亡率.
- 识别与NEC相关的BSI的风险因素对于及时干预至关重要.
研究的目的:
- 调查新生儿诊断为死角 enterokolitis (NEC) 的血流感染 (BSIs) 相关的危险因素.
- 为了确定与NEC同时发生的新生儿BSI的预测因子.
- 确定BSI.的NEC患者死亡率的独立风险因素.
主要方法:
- 在2015年至2024年期间,在4个新生儿重症监护室 (NICU) 进行了多中心的回顾性病例控制研究.
- 使用单变量和多变量分析来确定与NEC-BSI相关的因素.
- 分析了关于妊娠年龄,出生体重 (BW),NEC阶段,手术NEC,白细胞 (WBC) 计数,血管压缩剂使用和呼吸支持的数据.
主要成果:
- 克莱布西埃拉 spp. 的种类. 是最常见的致病原体,导致NEC相关的BSI (23%).

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...

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...
