JAMA:急性呼吸衰竭儿童患者后续神经认知功能变化

2022-03-03 MedSci原创 MedSci原创

对于因呼吸衰竭接受重症监护,但出院后无严重认知障碍的儿童患者,其后续成长发育过程中智商表现略低于一般人群,但这种差异很小,临床意义尚不明确。

2005年,在美国约有23 700 名新生儿期外的儿童因急性呼吸衰竭接受了有创机械通气,虽然大多数患儿存活,但随后的长期并发症越来越受到关注,许多患儿伴有认知功能障碍。近日研究人员开展兄弟姐妹比较研究,考察了接受重症监护和有创机械通气的急性呼吸衰竭患儿的后续神经认知功能发育情况。


研究在美国31个PICU和相关神经心理学测试中心开展。患儿年龄在8岁或以下,在PICU入院前儿童大脑功能分类得分为1(正常),在PICU出院时小于或等于3(中度神经认知功能障碍或以下),纳入研究患儿的兄弟姐妹年龄在4至16岁之间,儿童大脑功能类别得分为1,无机械通气或全身麻醉史。研究的主要结果韦氏智力量表评估的智商。次要结果包括注意力、处理速度、学习和记忆、视觉空间技能、运动技能、语言和执行功能,评估在出院后3至8年进行。
患儿(n=121;55名女童)接受PICU护理的平均年龄为1.0岁,接受有创机械通气的平均时间为5.5天,接受测试的平均年龄为6.6岁。匹配的兄弟姐妹在平均年龄为8.4岁时接受测试。结果显示,年龄调整后患儿的平均智商低于其兄弟姐妹(101.5 vs104.3;平均差异-2.8)。在次要结果中,患儿在非语言记忆(平均差异-0.9)、视觉空间技能(平均差异-0.9)和精细运动控制(平均差值,-3.1)方面的得分显著低于其兄弟姐妹,在处理速度方面(平均差值,4.4)的得分显著高于其兄弟姐妹。其他次要结果,包括注意力、语言记忆、表达性语言和执行功能,方面没有显著差异。
