Birthing process and development in the first 3 years Flashcards
reviewer
Neonatal Period
First four weeks of life, a time of transition from intrauterine dependency (a baby grows inside the mother’s womb) to independent existence
(organism surviving without depending on anything).
First few dates of neonates
(newborn babies)
They lose 10 percent of their body weight, primarily due to a loss of fluids.
Fifth Day of neonates
They begin to gain weight again
Tenth to the fourteenth day of neonates
They are generally back to their birth weight.
Distinct features of new babies
Large head (one-fourth the body length) and a receding chin (sloping backwards the neck which makes it easier to nurse.)
Reason for new babies distinct features
Due to the molding that eased its passage through the mother’s pelvis, which occurs because an infant’s skull bones are not yet fused, it will not be completely joined for 18 months.
Accomplished through the mother’s body before birth
Blood circulation, respiration, nourishment, elimination of waste and temperature regulation.
After birth
All of the baby’s systems and functions must operate on their own that occurs during the first four to six hours after delivery.
Fetus and mother
Has separate circulatory systems and umbilical cord; fetus blood is cleansed through the umbilical cord which carries used blood to the placenta and returns a fresh supply.
Neonate’s blood
Circulates wholly within the baby’s body. The heartbeat at first is fast and irregular and blood pressure does not stabilize until about ten days after birth.
Fetus
Gets oxygen from the umbilical cord, which also carries away carbon dioxide.
Most babies start to breathe as soon as they are exposed to air.
If breathing has not begun within about five minutes, the baby may suffer permanent brain injury caused by anoxia (lack of oxygen) or hypoxia (a reduce oxygen supply).
Infants can be suceptible to respiratory problems
Infants have only one-tenth as many air sacs in their lungs as adults.
Anoxia or Hypoxia
May occur during delivery as a result of repeated compression of placenta and umbilical cord with each contraction. This form of birth trauma can leave permanent brain damage, causing mental retardation, behavioral problems or even death.
Uterus
It is where the fetus relies on the umbilical cord to bring food from the mother and to carry fetal body wastes away.
