To assess the relationship between cerebral oxygenation in the first 72 h of life and neurodevelopmental impairment (NDI) at 2 years corrected age in former premature infants.
Prospective observational cohort study of 127 infants <32 weeks GA at birth with cerebral oxygenation monitoring using NIRS in the first 72 h of life.
Using a threshold cutoff for cerebral hypoxia, infants with NDI or death had increased duration of hypoxia (4 vs 2.3%, p = 0.001), which was more pronounced in the 23-27 week subgroup (7.6 vs 3.2%, p < 0.001). Individual generalized estimating equations to adjust for repeated measures were modeled in this subgroup for the physiologic parameters including StO. StO < 67% was a predictor for death or NDI (OR 2.75, 95% CI 1.006, 7.5132, p = 0.049).
An increased duration of cerebral hypoxia is associated with NDI or death in infants born <32 weeks GA.
评估生命最初 72 小时内的脑氧合与校正年龄 2 岁时神经发育障碍(NDI)之间的关系。
对 127 名出生时胎龄<32 周的早产儿进行前瞻性观察队列研究,在生命最初 72 小时内使用近红外光谱(NIRS)监测脑氧合。
使用脑缺氧的阈值截定点,患有 NDI 或死亡的婴儿缺氧持续时间更长(4% vs 2.3%,p=0.001),在 23-27 周亚组中更为明显(7.6% vs 3.2%,p<0.001)。对该亚组的生理参数(包括 StO)进行了个体广义估计方程以进行重复测量校正。StO<67%是死亡或 NDI 的预测因子(OR 2.75,95% CI 1.006,7.5132,p=0.049)。
出生胎龄<32 周的婴儿脑缺氧持续时间延长与 NDI 或死亡相关。
