Primary Outcome
Intrauterine cerebral blood flow development of neonates,Extrauterine cerebral blood flow development of neonates
Summary
Recently, with the development of perinatal medicine in China, the establishment of neonatal
 intensive care unit (NICU) and the improvement of respiratory support technology, the
 survival rate of preterm and term neonates has been significantly improved. However, the
 brain development of preterm neonates is incomplete compared with that of full-term neonates.
 Therefore, during the extrauterine cultivation of preterm neonates, clinical intervention
 should be carried out according to their brain development to achieve the same development
 status as that of full-term neonates. There are many clinical inspection methods to monitor
 the brain development of preterm neonates, such as EEG, functional near-infrared spectroscopy
 imaging, etc. However, these technologies cannot assess the brain development of premature
 infants systematically and completely. Because of the existence of neurovascular coupling,
 brain function and cerebral blood flow are closely related, so the detection of cerebral
 blood flow can reflect brain development and brain function. Ultrafast ultrasound power
 Doppler imaging technology is an emerging, real-time, high-resolution microvascular imaging
 technology. In this study, we first used ultrafast ultrasound power Doppler imaging
 technology to image the cerebral blood flow of preterm neonates at different gestational ages
 to evaluate the development of cerebral blood flow of preterm and term neonates and provide
 guidance for the clinical intervention of preterm neonates.
