JAMA:红细胞输注量与极低体重新生儿不良预后风险

2020-08-12 MedSci原创 MedSci原创

研究认为,对于出生体重小于1000克的婴儿中,不限制红细胞输注量不能降低患儿24个月时死亡或残疾风险

对于出生时体重小于1000克的婴儿,临床上通常进行红细胞输注治疗,但输血量的多少目前尚无充分的研究。先前有研究表明,较低的输血量似乎与认知障碍风险相关。近日研究人员考察了低体重新生儿红细胞输血量与死亡或残疾的相关性。
 
本次研究在欧洲36家新生儿重症监护中心开展,总计1013名出生体重在400克至999克之间的婴儿在出生后72小时内进组,其中492名新生儿不限制红细胞输血量(自由输注组),而对521名患儿红细胞输血量进行限制(限制输注组)。研究的主要终点为24个月时死亡或残疾(任何认知缺陷、脑瘫或严重的视觉或听觉障碍)。次要终点为早产并发症和生长发育情况。
 
患儿出生平均胎龄为26.3周,女婴占50.2%,91.6%的参与者完成了研究。自由输血组和限制输血组婴儿中,任何输血率分别为81.3%和60.5%,平均输血量分别为40ml和19ml。自由输注200名患儿出现主要终点事件(44.4%),而限制输注组205名患儿出现终点事件(42.9%),24个月内死亡分别为38例(8.3%)和44例(9.0%),认知功能缺陷分别为154例(37.6%)和148例(34.4%),脑瘫分别为18例(4.3%) 和25例(5.6%),需要手术治疗的坏死性小肠结肠炎分别为20例(4.1%)和28例(5.4%),支气管肺发育不良发生分别为130例(28.4%)和 126例(26.0%),需要治疗的早产儿视网膜病变分别为41例(8.7%)和38例(7.7%)。
 
研究认为,对于出生体重小于1000克的婴儿中,不限制红细胞输注量不能降低患儿24个月时死亡或残疾风险。
