The transferred child is an infant born after the 42nd week of gestation.
Reasons for child retention are usually unknown. Very rarely, this can occur because of anomalies that affect the pituitary-adrenal fetal system (eg, anencephaly or adrenal adenosis).

What happens with a delayed pregnancy?
When there is an overflow, there is an involution of the placenta, and numerous infarctions and degeneration of the villi lead to the development of placental insufficiency syndrome. In this syndrome, the fetus does not receive enough nutrients from the mother, which leads to soft tissue hypotrophy. During delivery, the infants born are prone to asphyxiation; a syndrome of meconial aspiration, which can be unusually heavy due to a decrease in the overflow of the amniotic fluid volume and, consequently, aspiration of less dilute meconium; neonatal hypoglycemia due to inadequate glycogen stores at birth. Since in the anaerobic pathway of glucose metabolism the remaining glycogen stores are rapidly used, hypoglycemia is enhanced if perinatal asphyxia occurs.
Symptoms of a born child
The migrated child is mobile and looks mature, but has a lowered layer of subcutaneous fat. The skin can hang freely on the limbs, dryness and flaking are often noted. The nails on the arms and legs are long. Nails and umbilical cord can be stained with meconium, which has receded in utero. The diagnosis is made on the basis of clinical examination and the expected date of delivery.
What is the prognosis of a born child?
The delayed child has a different prognosis, which depends on timely treatment and concomitant complications. In infants with meconial aspiration, in the absence of treatment, chronic respiratory failure and secondary pulmonary hypertension may develop; often substitution therapy with surfactant is useful.
