Persistent transitional circulation

Persistent transitional circulation.

Brown, R., and Pickering, D. (1974). Archives of Disease in Childhood, 49, 883. Persistent transitional circulation. Six infants presented within 24 hours of birth with cyanosis. The clinical findings, combined with catheter studies in 4 cases, led to the conclusion that there was a persistent fetal direction of ductus arteriosus flow with pulmonary hypertension, i.e. a 'persistent transitional...

Dopamine infusion for the treatment of myocardial dysfunction associated with a persistent transitional circulation.

Four infants with myocardial dysfunction associated with a persistent transitional circulation were given dopamine infusions in addition to standard treatment. The condition of each improved strikingly with rapid diminution in heart size as judged by chest x-ray. Dopamine has a place in the management of the sick infant with a persistent transitional circulation.

Physiology of the fetal and transitional circulation.

The fetal circulation is an entirely transient event, not replicated at any point in later life, and functionally distinct from the pediatric and adult circulations. Understanding of the physiology of the fetal circulation is vital for accurate interpretation of hemodynamic assessments in utero, but also for management of circulatory compromise in premature infants, who begin extrauterine life ...

Prostacyclin concentrations and transitional circulation in preterm infants requiring mechanical ventilation.

AIM To describe the association between early postnatal prostacyclin concentrations in preterm infants; echocardiographic measurements of ductal diameter and ventricular output and clinical outcomes of intraventricular haemorrhage (IVH) and patent ductus arteriosus (PDA). METHODS Forty nine preterm infants born before 30 weeks of gestational age (median birthweight 980 g, median gestational a...
