Understanding More About HIE
When the brain is deprived of sufficient supply of oxygen, it causes brain cell injury. In this process, some cells may die and some might just survive. Low oxygen levels in the blood or the reduced flow of oxygen to the brain are the two major causes for oxygen deprivation. As a matter of fact, there are a number of ways to how this may just happen such as before birth, during birth process, after birth and to some, during childhood.
Perinatal asphyxia, perinatal encephalopathy, neonatal encephalopathy or birth asphyxia are actually some of the alternate diagnosis for this condition. In reality, HIE injury can happen in two stages, one of it is that it can happen almost immediately after oxygen deprivation and the other is when the normal oxygenated blood circulation has resumed to the brain. Fact is, this is also called as reperfusion injury by experts which could happen because the toxins are released from the damaged cells.
There are countless of parents who are still puzzled what and how HIE. On the What part, you may be surprised that there are so many causes for HIE and these include near SIDS events, cardiac arrests, placental blood clots, aneurysm rupture, cord prolapsed, trauma during delivery, extremely low maternal blood pressure, true umbilical knots, placental abruption, uterine rupture, placental insufficiency, shoulder dystocia, cord compression, fetal maternal hemorrhage and maternal blood clotting disorders.
As for the diagnosis of HIE in newborn baby, this is carried out by using several diagnostic tools and among which is the Sarnat Scale. Basically, this is based on how the baby appears after an injury or birth or presentation at hospital. Not only that, it may be diagnosed by using imaging such as MRI, ultrasound and EEG while there are some who check cord blood gas levels.
As for the treatment of HIE, this one will check at the criteria first. More often than not, it has shown to reduce disability and death as well to perform cooling or therapeutic hypothermia. You may find it hard to believe one of the most popular and most suggested is the cooling treatment. Well of course, it isn’t the only treatment used as there are many of them used across the globe.
As for the therapeutic hypothermia, it can be done on the entire body or via the cooling cap that’s placed on the head. While the newborn is on their recovery period, they may be given with other medical intervention to support organs.
On the other hand, the rate of babies are diagnosed with HIE is quite a few on a ratio of 2 to 3 babies in every 1000 full term births are HIE affected every single year.
