Advances in the application of Doppler ultrasonography in the newborn

Heart rate monitoring in the delivery room has been explored with an exponential interest in the application of DUS for assessment at birth and/or during neonatal resuscitation [1]. High-resolution duplex ultrasound can detect ischemic strokes and DUS can differentiate complete occlusion from severe stenosis safely and non-invasively. [...]DUS guides therapeutic measures on the basis of recanalization of vessels and visualization of cyst formation from liquefactive necrosis. Though limited in sample size and perhaps flow velocimetry signal interference in low perfusion septic infants, we believe this application may become clinically practical.
