We prospectively and longitudinally evaluated neurologic status, cognitive status, and visual-evoked responses in 63 premature infants with cerebral intraventricular hemorrhage, 27 premature infants without hemorrhage, and 22 full-term normal infants. We hypothesized that severe intraventricular hemorrhage (grades III and IV) is associated with impaired visual-motor function, in part because of compression-related injury of the periventricular white matter by ventricular dilation. Infants with grade III or IV hemorrhage had significantly more neurologic sequelae at term and at 3, 7, 12, and 24 months; lower Bayley mental and motor scores at 3, 7, and 12 months; more abnormality on Kohen-Raz subscales for eye-hand coordination, object manipulation, and object relations at 3, 7, and 12 months; and lower Mullen vision-receptive and vision-expressive coordination scores at 24 months. The 12-month visual-evoked response correlated with the 24-month vision-receptive and vision-expressive organization scores for infants with grade III or IV intraventricular hemorrhage (r = -0.49, p less than 0.01, and r = -0.40, p less than 0.05, respectively). The data confirm our hypotheses of increased cognitive and neurologic sequelae, and increased abnormality of visual-motor coordination, during the first 2 years of life in infants with severe (grade III or IV) intraventricular hemorrhage.
我们对63例患有脑室内出血的早产儿、27例无出血的早产儿和22例足月儿进行了前瞻性和纵向的神经状态、认知状态及视觉诱发电位评估。我们假设严重的脑室内出血(III级和IV级)与视觉运动功能受损有关,部分原因是脑室扩张对脑室周围白质造成的压迫性损伤。III级或IV级出血的婴儿在足月时以及3、7、12和24个月时神经后遗症明显更多;在3、7和12个月时贝利智力和运动评分更低;在3、7和12个月时,在科恩-拉兹量表的眼手协调、物体操作和物体关系方面异常更多;在24个月时穆伦视觉接受和视觉表达协调评分更低。对于III级或IV级脑室内出血的婴儿,12个月时的视觉诱发电位与24个月时的视觉接受和视觉表达组织评分相关(分别为r = -0.49,p < 0.01,以及r = -0.40,p < 0.05)。数据证实了我们的假设,即在患有严重(III级或IV级)脑室内出血的婴儿出生后的头2年里,认知和神经后遗症增加,视觉运动协调异常增加。
