Diagnosis and management of hypotension in premature infants at early postnatal stage / 国际儿科学杂志

ABSTRACT

Hypotension is a common complication in preterrn infants during the first 2 weeks after birth.For preterminfants,the transition from fetal circulation to normal cycle in the early stage after birth is complex.The cardiovascular system is immature.Due to the early delivery,a sudden increase in vascular resistance let the premature to suffer from hypotension and circulatory insufficiency in the postnatal days.In the premature neonate,there is no consensus regarding normal blood pressure,while management and prognosis vary considerably in different neonatal institutions.The current clinical management involves volume expansion,inotropes (includes dopamine,dobutamine,epinephrine,etc.),glucocorticoid and closing the arterial catheter.Whether these treatments can improve the outcomes of premature infants need to be confirmed.This review summarizes the definition and management starus of hypotension in premature infants at transition period.
