Changes of cerebral blood flow were determined in 20 preterm infants undergoing blue-light phototherapy for hyperbilirubinemia. All were healthy very-low-birth-weight infants (less than 1,500 g) with normal brain sonograms and not under pharmacological treatment at the time of the investigation. Blood flow velocity (pulsatility index and area under velocity curve) was measured by Duplex Scan technique during and after phototherapy. No changes of global cerebral blood flow were observed in the anterior cerebral artery (p less than 0.5). Our results suggest no functional disturbance of cerebral autoregulation in low-birth-weight infants treated with phototherapy.
对20名因高胆红素血症接受蓝光光疗的早产儿的脑血流变化进行了测定。所有患儿均为健康的极低出生体重儿(体重不足1500克),脑超声图正常,且在调查时未接受药物治疗。在光疗期间及光疗后,采用双功扫描技术测量血流速度(搏动指数和速度曲线下面积)。大脑前动脉未观察到全脑血流变化(p<0.5)。我们的结果表明,接受光疗的低出生体重儿脑自动调节功能无紊乱。
