概括
在早产婴儿的肠道补充剂改善了生长和体重增加,但没有增加高血压或高血的风险. 然而,产后类固醇与高血压有关.
科学领域:
- 新生儿生理和营养新生儿生理和营养
- 儿科病学和心脏病学
背景情况:
- 过早出生的婴儿通常会经历低于最佳的生长和电解质失衡.
- 肠道补充是一种常见的做法,但它对生长和高血压风险的影响需要进一步调查.
研究的目的:
- 评估肠道补充剂与早产婴儿生长参数之间的关联.
- 评估肠道补充剂与这种脆弱人群中高血压 (HTN) 的发展之间的关系.
主要方法:
- 追溯队列研究包括821名早产婴儿 (怀孕22-32周,出生体重450-1500克).
- 提取了关于肠道补充剂,静脉血压 (SBP),体重增加和潜在混因素的数据.
- 统计分析,包括调整的赔率比率 (ORADJ),用于确定关联.
主要成果:
- 接受补充剂的婴儿更小,更不成熟.
- 补充剂改善了血清水平,体重增加和头周长增长,而不会导致高血症.
- 尿液和血清或尿液和体重增加之间没有发现显著的相关性.
- 虽然接受的婴儿的平均SBP和HTN率较高,但补充剂并没有增加高血压的几率 (ORADJ 1.02; 0.64-1.64).
- 产后使用类固醇与HTN风险增加有关.
结论:
- 肠道补充剂可以安全地增强早产婴儿的生长,体重增加较差.
- 这种补充策略似乎不会增加高血压或高血的风险.
- 产后使用类固醇是早产婴儿高血压的重要危险因素.
