概括
对隔膜动力学的超声波评估显示,LISA和INSURE表面活性剂在早产婴儿的施用方法之间没有显著差异. 这些发现表明,无论采用哪种技术,膜沉积和呼吸顺应都类似.
科学领域:
- 新生儿医学 新生儿医学
- 呼吸系统生理学 呼吸系统生理学
- 医学超声波 医学超声波
背景情况:
- 有关表面活性剂在较少侵入性表面活性剂管理方法 (LISA) 和内腔表面活性剂管理方法 (INSURE) 之间的表面活性剂膜沉积差异存在担忧.
- 隔膜动力学的超声波评估提供了潜在的呼吸系统合规性的间接测量,这可能会阐明表面活性剂沉积的差异.
- 了解这些差异对于优化患有呼吸困扰综合征 (RDS) 的早产婴儿的呼吸支持至关重要.
研究的目的:
- 调查不同的最小侵入性表面活性剂施用技术 (LISA与INSURE) 是否会影响隔膜动力学.
- 用脉冲波组织多普勒成像 (PTDI) 来评估隔膜全球平均峰值速度 (MPV) 作为呼吸系统符合性指标.
- 探索接受表面活性剂治疗的早产婴儿的隔膜动力学和治疗结果之间的关系.
主要方法:
- 展望观察试点研究涉及52名婴儿 (妊娠年龄≤32周) 患有RDS,通过LISA或INSURE接受表面活性剂.
- 右隔膜 (RD) 全球平均峰值速度 (MPV) 通过PTDI测量在施用表面活性剂之前和施用表面活性剂后2小时.
- 同时监测氧和度 (SpO2) /吸入氧 (FiO2) 比率 (SF比率) 的分数;在72小时内进行机械通风.定义治疗失败.
主要成果:
- 与INSURE婴儿相比,LISA婴儿的妊娠年龄,出生体重和CRIB-II分数较高,而且较低.
- 虽然LISA婴儿显示出更高的基线RD-PTDIMPV,但在经过调整后的分析后,表面活性剂后的MPV和SF比率在各组之间相似.
- 治疗失败的婴儿 (n=8) 呈现较低的SF比率和较高的RD-PTDI MPV后表面活性剂,尽管增加了CPAP支持.
结论:
- 通过RD-PTDI超声波评估的隔膜动力学似乎不受LISA和INSURE表面活性剂施用技术之间的选择显著影响.
- 这项研究表明,这两种最小侵入性表面活性剂输送方法对呼吸系统的符合性有可比的影响.
- 产前类固醇的使用与减少对机械通风的需求有关.

Physical Assessment of the Respiratory Tract III: Percussion
515
The respiratory system, fundamental to life, consists of complex structures responsible for gas exchange. The percussion assessment is critical to understanding this system's health and functionality. This non-invasive assessment technique allows healthcare providers to evaluate the density or aeration of the lungs, thereby identifying potential abnormalities.

Assessment of Ventilation II: Respiratory Depth and Rhythm

Respiratory Depth
Respiratory depth measures the volume of air inhaled or exhaled during a breath. It can vary from shallow to deep and typically remains consistent when a person is at rest or asleep. Occasionally, individuals will automatically inhale deeply, known as sighing, which inflates the lungs with more air than normal breathing.
To assess respiratory depth, observe the degree of chest excursion or movement:
