The objectives were to describe mortality and causes of death in children with intraventricular hemorrhage (IVH) and to study neurodevelopmental outcomes.
The study was a secondary analysis of the French national prospective and population-based cohort EPIPAGE-2. Children were recruited in 2011. A standardized assessment was conducted at age 5. Children born before 32 weeks' gestation and admitted to a NICU were eligible. Exposure was IVH defined by the Papile classification. Main outcomes were mortality, causes of death, and neurodevelopmental outcomes at age 5.
Among the 3468 children included, 578 (16.7%) had grade 1 IVH, 424 (12.2%) grade 2 IVH, and 114 (3.3%) grade 3 IVH; 144 (4.1%) had intraparenchymal hemorrhage (IPH). Mortality was 29.7% (36 of 114) for children with grade 3 IVH and 74.4% (109 of 144) for those with IPH; 67.6% (21 of 31) and 88.7% (86 of 97) of deaths, respectively, were because of withholding and withdrawing of life-sustaining treatment. As compared with no IVH, low-grade IVH was not associated with measured neurodevelopmental disabilities at age 5. High-grade IVH was associated with moderate and severe neurodevelopmental disabilities, reduced full-scale IQ, and cerebral palsy.
Rates of neurodevelopmental disabilities at age 5 did not differ between children without IVH and those with low-grade IVH. For high-grade IVH, mortality rate was high, mostly because of withholding and withdrawal of life-sustaining treatment, and we found a strong association with overall neurodevelopmental disabilities in survivors.
本研究旨在描述脑室周围出血(IVH)患儿的死亡率和死因,并研究其神经发育结局。
本研究是法国前瞻性、基于人群的 EPIPAGE-2 队列的二次分析。研究于 2011 年招募患儿,在 5 岁时进行标准化评估。本研究纳入胎龄<32 周且入住新生儿重症监护病房(NICU)的患儿。IVH 通过 Papile 分级进行定义。主要结局为 5 岁时的死亡率、死因和神经发育结局。
在纳入的 3468 例患儿中,578 例(16.7%)存在 1 级 IVH,424 例(12.2%)存在 2 级 IVH,114 例(3.3%)存在 3 级 IVH;144 例(4.1%)存在脑实质内出血(IPH)。3 级 IVH 患儿的死亡率为 29.7%(36/114),IPH 患儿的死亡率为 74.4%(109/144);分别有 67.6%(21/31)和 88.7%(86/97)的死亡是由于放弃和撤除生命支持治疗。与无脑室周围出血患儿相比,低级别 IVH 患儿在 5 岁时并未出现神经发育障碍。高级别 IVH 与中度至重度神经发育障碍、全量表智商降低和脑瘫相关。
无 IVH 患儿与低级别 IVH 患儿在 5 岁时的神经发育障碍发生率无差异。对于高级别 IVH,死亡率较高,主要是由于放弃和撤除生命支持治疗,我们发现存活者的总体神经发育障碍与高级别 IVH 密切相关。
