P91.6: Hypoxic ischaemic encephalopathy of newborn

An inadequate blood supply and oxygen supply have damaged areas in the child's brain.

The brain is located inside the head. It receives, processes and stores sensory impressions. The brain controls movements and various physical functions. If the brain is to be able to exercise its functions, it has to have an adequate supply of blood and oxygen.

There can be various reasons why the baby's brain does not get an adequate supply of blood and oxygen. For example, the child will not get enough oxygen if there are problems with the placenta while in the womb. The placenta forms in the mother’s womb during pregnancy. The placenta consists of cells from the mother and cells from the unborn child. The umbilical cord connects the child to the placenta. The child is normally supplied with oxygen from the mother's blood via the placenta.

If there are problems with the child's blood supply during the birth, likewise, the child will not get enough oxygen. The blood supply can be interrupted during the birth if, for example, the umbilical cord is knotted or looped. After the birth congenital heart defects, a loss of blood or bleeding in the brain can result in the brain not getting enough blood and oxygen.

If the brain has been damaged, the child may have a variety of indications. For example, the child's reflexes might be changed. A reflex is the body's response to a stimulus. This response can be a muscle movement, for example. As time goes on, its muscles might be weak and muscle tension low. It may also have breathing problems. The baby might also be particularly sleepy. It may also have seizures.
