Preterm Birth


Preterm Birth
Preterm birth refers to the birth of babies who are less than 37 weeks in the womb. It is commonly called premature birth. This is the major cause of neonatal mortality in developed countries. That is because they have high risk of death in the first year of life. They have several health problems that occur in this period.
The most common problem is respiratory problem. That is because lung is one of the last organs which develop in pregnancy. A common respiratory problem for them is respiratory distress syndrome (RDS). According to Martin J.A in Final Data for National Statistic Report, about 23.000 babies a year, most of them are born before the 34th week of pregnancy, suffer from this breathing problem. Babies with RDS lack a protein called surfactant. It keeps small air-sac, alveolus, in the lungs from collapsing. Treatment with surfactant helps them breathe more easily. However, the sickest baby needs the help of a ventilator to breathe while their lungs mature.
Premature babies are also in high risk of infection. That is because their immune has not mature yet, so it is inefficient at fighting bacteria, viruses and other organisms that can cause infection. Serious infections that commonly seen in premature babies are pneumonia- lung infection, sepsis- blood infection and meningitis- infection of the membranes surrounding the brain and spinal cord.
The others problem are that related to brain, vision, kidney and digestive system. They can get intra-ventricular hemorrhage (IVH). It is a bleeding in the brain. It usually occurs in the first 3 days of life. Most of brain bleeds are mild and can resolve themselves. In vision problem, there is retinopathy of prematurity (ROP). It is an abnormal growth of blood vessels in the eye that can cause vision loss. The disease in kidney is jaundice. It is inability to remove a waste product called bilirubin from the blood. Jaundice is often mild and is not harmful. However, if bilirubin concentration in blood is too high, it can cause brain damage. Necrotizing enterocolitis (NEC) is happen in digestive system. It causes feeding difficulties and abdominal swelling.
In short, premature babies face a lot of dangerous things in their first year of life. They are in high risk of death because of several health problems. It is a miracle of God when they can live until they are adult and do not have any differences from others.
