Abstract

<p> Objectives: The purpose of this study was to clarify the correlation between the resistance index（RI）or pulsatility index（PI）and cerebral perfusion pressure using transcranial ultrasonography（estimated cerebral perfusion pressure: CPPe）in newborns.</p><p> Methods: Neonates admitted to the neonatal intensive care units between December 2021 and May 2023 after 32 weeks of gestation and with continuous arterial pressure measurements were included in this study. We calculated the RI, PI, and CPPe from flow waveforms of the middle cerebral artery obtained by transcranial ultrasonography once a day, and examined the relationships between RI or PI and CPPe in preterm and term infants.</p><p> Results: The study population consisted of 24 preterm（mean age at birth: 34.4 ± 1.4 weeks and mean birth weight: 1,929 ± 590 g）and 28 term（38.2 ± 1.2 weeks and 2,729 ± 704 g）infants. RI and PI were significantly correlated with CPPe, respectively.</p><p> Conclusions: RI and PI may be used to predict cerebral perfusion pressure in neonates.</p>
