How Much You Know 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. A very common cause for oxygen deprivation to our brain is the low oxygen levels in our blood or perhaps, the reduced flow of oxygen to our brain. 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. There are a couple of stages for HIE injury with the first being immediately right after the oxygen deprivation while the second takes place as the normal oxygenated blood circulation resumes to the brain. This is otherwise referred to is reperfusion injury and happens as toxins are being released from damaged cells.
There are countless of parents who are still puzzled what and how HIE. Well for the What part, there are numerous factors that might just cause HIE including true umbilical knots, placental abruption, uterine rupture, placental insufficiency, trauma during delivery, extremely low maternal blood pressure, maternal blood clotting disorders, cord compression, aneurysm rupture, cord prolapsed, fetal maternal hemorrhage, shoulder dystocia, placental blood clots, cardiac arrests as well as near SIDS events.
In regards to the diagnosis of a newborn baby HIE, experts perform this by making use of diagnostic tools such as the Sarnat Scale. Basically, this is based on how the baby appears after an injury or birth or presentation at hospital. In addition to that, it can be diagnosed as well through imaging similar to MRI, ultrasound and EEG while other health experts are checking for cord blood gas levels.
Before devising a treatment plan for HIE, it will be necessary to know some criteria first. But most of the time, it has revealed to reduce disability and death to do cooling or therapeutic hypothermia. Whether you believe it or not, the cooling treatment is widely used. Of course, this is not the only available treatment you can use since there are many of them worldwide.
When it comes to therapeutic hypothermia, it could be done through a cooling cap placed on the head or by cooling the entire body. The baby may be given with other medical treatments to be able to stop seizures or to support organs while they are on their recovery period.
The rate of babies diagnosed with HIE on the other hand runs on a ratio of 2 to 3 babies in every 1000 full term births.
