概括
婴儿心脏手术可以降低免疫球蛋白G (IgG) 水平,增加感染风险. 在先天性心脏病 (CHD) 手术后监测IgG水平可能有助于识别需要治疗的婴儿.
科学领域:
- 儿童心脏病学 儿童心脏病学
- 免疫学 免疫学 免疫学
- 手术重症监护手术重症监护
背景情况:
- 患有先天性心脏病 (CHD) 的婴儿通常需要在生命的第一年内进行手术.
- 心脏病手术引发全身炎症和血液稀释,可能会耗尽循环中的免疫球蛋白 (Ig).
研究的目的:
- 在接受心脏病手术的婴儿中量化免疫球蛋白水平 (IgG,IgA,IgM).
- 评估免疫球蛋白减少,心肺旁路 (CPB) 特性和临床结果,包括术后感染之间的关联.
主要方法:
- 对300名接受心脏病手术的婴儿 (<12个月) 进行前性观察队列研究.
- 在四个外科手术期间的时间点对IgG,IgA和IgM的量化.
- 使用多变量后勤和线性模型进行分析,以确定感染和Ig耗尽的预测因素.
主要成果:
- 手术后24小时平均IgG降低了23%,CPB持续时间较长与IgG下降更大相关.
- 术后感染发生在17%的婴儿中,与较低的IgG水平和长时间的ICU停留有关.
- 较低的基线IgG,较长的CPB时间,较低的妊娠年龄和更高的外科复杂性独立预测感染.
结论:
- 显著的早期术后IgG耗尽与婴儿心脏病手术后感染风险增加和ICU利用率增加有关.
- 术前免疫球蛋白监测可以帮助分层风险,并确定免疫球蛋白干预的候选人.

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...

Development of Immunocompetence

The initiation of cell-mediated immunity can be observed as early as the third month of fetal growth, with active antibody-mediated immunity following approximately one month later.
The initial cells that migrate from the fetal thymus settle within the skin and epithelial tissues lining the mouth, digestive tract, and in females, the uterus and vagina. These cells, including skin-based dendritic cells, serve as antigen-presenting cells, playing a key role in T cell activation.

Healthcare Associated Infections I: Iatrogenic, Exogenic and Endogenic
5.3K
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.

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...
