概括
在NICU中早产婴儿的非侵入性通风 (NIV) 与增加的鼻腔微生物殖民有关. 这凸显了对脆弱新生儿加强感染控制策略的需要.
科学领域:
- 新生儿重症监护室 (NICU) 的研究.
- 微生物学和传染病.
- 在新生儿的呼吸支.
背景情况:
- 在NICU的早产婴儿容易受到微生物的殖民.
- 非侵入性通风 (NIV) 通常用于新生儿的呼吸支.
- NIV对早产婴儿发育中的微生物群的影响需要进一步研究.
研究的目的:
- 评估非侵入性通风 (NIV) 与口腔/鼻腔微生物群殖民之间的关联.
- 在NICU环境中评估早产婴儿 (怀孕28至35周) 的殖民化.
- 确定与不同呼吸辅助方法相关的微生物殖民风险.
主要方法:
- 一项前性队列研究,涉及100名早产婴儿 (怀孕28至35周).
- 婴儿分为NIV组 (CPAP,NIPPV,HFNC) 和没有呼吸辅助组.
- 口腔和鼻腔微生物群的殖民化测量在出生后5天使用CFU/mL;>10^3CFU/mL定义为殖民化.
主要成果:
- 与没有呼吸辅助组 (28%) 相比,NIV组的鼻腔微生物殖民率明显高 (56%).
- 两组之间没有观察到口腔微生物群殖民的显著差异.
- 尼维与鼻腔殖民的风险增加有关 (调整后OR=2.91,p=0.028).
结论:
- 在早产婴儿中,非侵入性通风与鼻腔微生物殖民的更高发病率有关.
- 这些发现表明,需要针对接受NIV.的新生儿采取针对性的感染控制措施.
- 需要进一步的研究来探索机制并制定预防策略.

Mechanical Ventilation II: Invasive Ventilation
114
Ventilators are essential medical equipment used to aid patients with respiratory difficulties. Their primary function is to assist or replace spontaneous breathing by providing mechanical ventilation. There are two general classes of mechanical ventilators: negative-pressure and positive-pressure ventilators.
Negative-Pressure Ventilators
Negative-pressure ventilators create a vacuum around the chest or body to draw air into the lungs, simulating breathing. This method does not require an...

Mechanical Ventilation III: Noninvasive Ventilation
81
Noninvasive positive-pressure ventilation (NIPPV), continuous positive airway pressure (CPAP), and bilevel positive airway pressure (BiPAP) are essential methods in respiratory care. These ventilation techniques offer unique benefits for patients with various respiratory conditions, providing adequate support without requiring intubation. Let's explore how each method is crucial in improving patient outcomes and enhancing respiratory therapy.

Mechanical Ventilation I: Indication and Settings
183
Mechanical ventilation is a life-saving technique for managing acute respiratory failure and other respiratory complications. The process involves using a machine known as a ventilator to supply oxygen to the lungs and assist in removing carbon dioxide. It serves as a bridge to long-term mechanical ventilation or a temporary measure until ventilatory support is discontinued. The ventilator can maintain this function for a prolonged period, providing critical support for patients until they can...
