Abstract
The validation of measurement of cerebral blood volume (CBV) and cerebral blood flow (CBF) using near infrared spectroscopy (NIRS) against jugular venous occlusion plethysmography is described. Repeated measurements in six infants were made using both techniques simultaneously. A close relationship between the two measurements of change in CBV was obtained in five infants. There was also a close relationship for measurement of CBF in four infants. This study confirms the possibility of using NIRS to monitor CBV continuously in the premature infant. This parameter may prove to be of greater clinical value than the intermittent measurement of CBF.
摘要
描述了使用近红外光谱法（NIRS）测量脑血容量（CBV）和脑血流量（CBF）相对于颈静脉闭塞体积描记法的验证情况。对六名婴儿同时使用这两种技术进行重复测量。在五名婴儿中，两种测量CBV变化的方法之间存在密切关系。在四名婴儿中，CBF测量也存在密切关系。这项研究证实了使用NIRS连续监测早产儿CBV的可能性。该参数可能比间歇性测量CBF具有更大的临床价值。
