概括
在塑料包装之前干燥早产婴儿不会在新生儿重症监护室入院时改善正常热率. 热管理对于这些脆弱的新生儿来说仍然是一个关键的挑战,需要进一步的研究.
科学领域:
- 新生儿科学 新生儿科学
- 围产期护理 围产期护理
- 热调节 热调节 热调节
背景情况:
- 尽管新生儿护理方面取得了进展,但在早产婴儿出生后立即保持热稳定是一个持续的挑战.
- 有效的热管理策略对于改善非常早产婴儿的结果至关重要.
研究的目的:
- 为了比较两个热管理策略的有效性:用塑料包装干燥与不干燥的塑料包装.
- 评估这些策略对预防出生时非常早产婴儿的热量损失的影响.
主要方法:
- 一个多中心,未盲目的随机临床试验,涉及非常早产婴儿 (出生体重<1500g或妊娠年龄 ≤30周6天).
- 婴儿被随机分配到塑料包装前干燥或在分娩室不干燥的塑料包装.
- 主要结局是新生儿重症监护室 (NICU) 入院时的正常热 (36.5-37.5°C).
主要成果:
- 在干燥 (45.8%) 和未干燥 (46.3%) 组 (风险比,0.99;95% CI,0.79-1.24) 中,入院时的正常热度相似.
- 新生重症监护室入院的平均温度也相似: 36.4 °C (干燥) 和 36.5 °C (未干燥).
- 干燥组 (14.7%) 的住院死亡率高于未干燥组 (5.6%).
结论:
- 在塑料包装之前干燥非常早产的婴儿不会在新生儿重症监护室入院时改善正常热率.
- 热管理仍然是非常早产婴儿面临的重大挑战,大约一半的婴儿在NICU入院时处于正常温度范围之外.
- 需要进一步的研究,以确定最佳的热管理策略,为这个脆弱的人群.

01:31Plasticizers
Water-reducers, or plasticizers, are chemical admixtures used in concrete to improve strength and workability. These additives reduce the water-cement ratio without compromising workability, lower the cement content while maintaining the same workability, or increase workability to assist concrete placement in inaccessible areas.
Plasticizers function by using surface-active agents to create repulsive electrostatic forces between cement particles. This dispersion enhances the concrete's...

01:28Development of the Oral Microbiota
The establishment of the oral microbiome begins before birth, challenging the long-held belief that the fetal oral cavity is sterile. The presence of oral microbes such as Streptococcus and Fusobacterium in amniotic fluid suggests that microbial exposure may occur in utero, potentially through translocation from the maternal oral or gastrointestinal tract. This early colonization primes the neonatal immune system and sets the stage for subsequent microbial succession. Maternal health,...
