新生儿行为测定对围产期高危新生儿预后预测的意义

Neonatalbehavioralneurological assessm ent and prognosis forecast of high risk infants

目的 通过对围产期高危新生儿进行行为神经测定及长期随访，探讨新生儿行为在高危儿预后预测中的意义。方法 对高危儿及正常新生儿于新生儿期进行行为神经测定（ＮＢＮＡ），动态随访至１．５～２ 岁，进行婴幼儿智能发育测定（ＣＤＣＣ），研究ＮＢＮＡ 与ＣＤＣＣ得分的关系。结果 高危新生儿１．５ 岁时ＣＤＣＣ总得分明显低于正常，其中新生儿期ＮＢＮＡ低于３６ 分者６０％ １．５ 岁后可发生智力落后，而３６ 分以上者无一例发生智力低下。结论 新生儿期行为神经测定可较好地预测高危新生儿的预后。
