“…The therapeutic hypothermia, which is a standard of care for infants with moderate to severe hypoxic-ischaemic encephalopathy, may further affect the transition—it leads to high PVR, high SVR, sinus bradycardia associated with low cardiac output and it may further deteriorate cardiac function from increased afterload ( 29 , 30 ). A detailed mechanism is discussed in another article “advanced in diagnosis and management of shock” in Frontiers in Pediatrics ( 31 ).…”

The hemodynamic changes during the first few breaths after birth are probably the most significant and drastic adaptation in the human life. These changes are critical for a smooth transition of fetal to neonatal circulation. With the cord clamping, lungs take over as the source of oxygenation from placenta. A smooth transition of circulation is a complex mechanism and primarily depends upon the drop in pulmonary vascular resistance (PVR) and increase in systemic vascular resistance (SVR). Understanding the normal transition physiology and the adverse adaptation is of utmost importance to the clinicians looking after neonates. It may have a significant influence on the presentation of congenital heart defects (CHDs) in infants. Bedside echocardiography may help in understanding the transition physiology, especially the hemodynamic changes and shunting across ductus arteriosus and foramen ovale, and it may play an important role in making judicious clinical decisions based upon the altered physiology.
