Newborns with hypoxemia often require life-saving respiratory support. In low-resource settings, it is unknown if respiratory support is delivered more frequently to term infants or preterm infants. We hypothesized that in a registry-based birth cohort in 105 geographic areas in seven low- and middle-income countries, more term newborns received respiratory support than preterm newborns.
This is a hypothesis-driven observational study based on prospectively collected data from the Maternal and Newborn Health Registry of the NICHD Global Network for Women's and Children's Health Research. Eligible infants enrolled in the registry were live-born between 22 and 44 weeks gestation with a birth weight ≥400 g and born from January 1, 2015, to December 31, 2018. Frequency data were obtained to report the number of term and preterm infants who received treatment with oxygen only, CPAP, or mechanical ventilation. Test for trends over time were conducted using robust Poisson regression.
177,728 (86.3%) infants included in this study were term, and 28,249 (13.7%) were preterm. A larger number of term infants (n = 5,108) received respiratory support compared to preterm infants (n = 3,287). Receipt of each mode of respiratory support was more frequent in term infants. The proportion of preterm infants who received respiratory support (11.6%) was higher than the proportion of term infants receiving respiratory support (2.9%, p < 0.001). The rate of provision of respiratory support varied between sites.
Respiratory support was more frequently used in term infants expected to be at low risk for respiratory disorders compared to preterm infants.
患有低氧血症的新生儿通常需要救生呼吸支持。在资源匮乏的环境中,尚不清楚呼吸支持是更多地提供给足月婴儿还是早产儿。我们假设,在七个中低收入国家的 105 个地理区域中,基于注册的出生队列中,接受呼吸支持的足月新生儿多于早产儿。
这是一项基于 NICHD 全球妇女和儿童健康研究网络的母婴健康注册处前瞻性收集数据的假设驱动观察性研究。有资格入组该注册处的婴儿为出生胎龄 22 至 44 周、出生体重≥400g、2015 年 1 月 1 日至 2018 年 12 月 31 日期间出生的活产儿。获取频率数据以报告接受仅吸氧、CPAP 或机械通气治疗的足月和早产儿人数。使用稳健泊松回归进行时间趋势检验。
本研究纳入的 177728 名(86.3%)婴儿为足月,28249 名(13.7%)为早产。与早产儿(n=3287)相比,接受呼吸支持的足月婴儿(n=5108)更多。接受每种呼吸支持模式的足月婴儿比例更高。接受呼吸支持的早产儿比例(11.6%)高于接受呼吸支持的足月婴儿比例(2.9%,p < 0.001)。各站点提供呼吸支持的比例不同。
与早产儿相比,预计患有呼吸疾病风险较低的足月婴儿更频繁地使用呼吸支持。
