Abstract:
Neonates are undergoing the transition period from fetal circulation to adult circulation, and the hemodynamic changes are complex.For premature infants(especially very low birth weight infants and extremely low birth weight infants), the cardiovascular systems are immature.Therefore, they are prone to hypotension at early postnatal stage.Hypotension may lead to multiple organ perfusion insufficience, cerebral lesion, and even death.However, it is not always accompanied by hypoperfusion.Before treatment, clinicians should evaluate the hemodynamics comprehensively.At present, there is no consensus on the definition and intervention threshold about hypotension in premature infants.This review summarizes the definitions and hemodynamic monitoring methods of hypotension in premature infants at early postnatal stage to provide references for diagnosis and treatments.
