A baby, born before completing 27 weeks of gestation period or a baby whose weight is very less due to preterm birth is considered to be a micro preemie. As the expectant mother knows that preterm labour has a lot of risks, she should consult a foetal medicine specialist to delay the process of delivery and prolong the pregnancy period. The medicines prescribed orally or vaginally help to delay the labour of the expectant mom.
What is a Micro Preemie?
A premature baby born before completing 26 weeks gestation period or weighs under 1.12 lb is called a micro preemie. For the micro preemie to thrive, you must know in advance that these babies are very different from full-term babies and their emotional and physical needs have to be catered to with great care and caution.
What Are the Causes of Giving Birth to a Micro Preemie Baby?
When a pregnancy ends early, it is difficult to assess the reasons, but one can say for sure that many factors combine to cause preterm birth. There are two categories of preterm labour – spontaneous preterm birth and medically compelled delivery. Some of the causes are given below:
- Any systemic inflammation or infection in the kidney, vagina, uterus, or mouth can cause spontaneous preterm delivery.
- Nicotine or any kind of tobacco prevents nutrients and oxygen from reaching the baby, thereby forcing preterm delivery.
- If the pregnancies are less than six months apart, it presents a high risk of delivering a preterm baby.
- It can also happen due to a genetic history in the family.
- If the cervix is insufficient or there are any other cervical problems, this can be the reason too.
Survival Rates of Micro Preemies
Micro preemies are very weak and fragile and so need a lot of monitoring and care. Utmost care is required to help the baby survive. The table given below indicates the survival rate depending on the week the baby was born:
|26 weeks||More than 90%|
|25 weeks||75% to 80%|
|24 weeks||66% to 80%|
|23 weeks||50% to 66 %|
|22 weeks or less||Only 10%|
How Does a Micro Preemie Look?
A micro preemie baby looks very tiny and weak. Their veins may be visible on their body, and their skin looks very thin and appears sticky or gelatinous.
In the NICU, they are also connected to various pieces of equipment, tubes and wires to help them sustain. You’ll see wired stickers on the baby’s legs, arms, feet, wrist or chest. There will also be a monitor attached to the umbilical artery IV line to measure blood pressure. Some may also have tubes in their mouth connected to a ventilator to help them breathe or are put on the continuous positive airway pressure (CPAP). OG/NG tubes will be attached to the baby’s mouth (OG) and nose (NG) to help with the feed.
Immediate and Short–term Health Concerns for Micro Preemies
Micro preemies are treated in NICU as they need a lot of external support. Some of the immediate and short-term concerns are given below:
Premature babies have an immature immune system. Infants get infections from the intravenous lines that are inserted in their weak bodies. Sometimes they catch a cold from a person who is suffering from cold. Good hygiene should be ensured to avoid it.
2. Support for Breathing
Premature babies do not have strong lungs to breathe on their own. They either help them breathe by intubating them or use a CPAP device which is non- invasive and less injurious to the lungs.
3. Issues with Feeding
The baby’s feeding and growth are one of the most important things to be monitored in the NICU. They are prone to vomiting, and so they are fed a very small amount of food to help the gut mature. After their gut attains maturity, they are introduced to formula feed.
4. Injury in the Brain
Micro preemies are always at high risk of brain bleeding. Brain ultrasounds are done to check whether the bleeding is mild or severe. The risk of severe brain bleeding can be neurodevelopmental disorders or cerebral palsy.
5. Problems in the Eye
When babies are born before the gestation period is complete, they may develop a condition that affects the retina’s blood vessels. As they are put on the high amount of oxygen for a prolonged period of time, their eyesight gets affected, and some require glasses as an aid to see clearly.
How Long Are Micro Preemies Kept in the NICU?
Babies who are born before 27 weeks are made to stay in NICU until they complete the full tenure of development or sometimes even more. They often require respiratory support with a ventilator, a CPAP or a nasal cannula. They also try to keep the baby nourished to gain weight and growth of the organs. This support is impossible to provide at home, and so their stay in NICU is a must during this time.
Long-term Health Issues in Micro Preemie
Micro preemies may develop some long-term health issues which are given below:
1. Learning Disabilities
Babies tend to develop physical, mental and emotional handicaps. They end up with cognitive problems, learning or behavioural problems.
2. Problems in Digestion
3. Hearing or Vision Problems
As complications of premature birth can be severe at times, they may ultimately have permanent hearing or vision loss, or related problems.
4. Lung Disease
Preemies require artificial respiratory support which sometimes leads to asthma or bronchopulmonary dysplasia, a chronic lung disease.
5. Cerebral Palsy
Some preemies may severe or moderate cerebral palsy.
How Parents Can Help in Improving Their Baby’s Outcome?
Parents can play a positive and significant role in their micro preemie’s development and to give their babies the best possible start.
1. Early Intervention
Parents should try to minimize the cognitive impact of prematurity by seeking early intervention.
2. Know the Signs of Preterm Labour
Expectant mothers should seek medical care the minute they get an inkling that they might have a preterm delivery.
3. Deliver in a Hospital With NICU
You must identify a good hospital with a level 3 NICU along with 24×7 neonatology coverage, so that the child can avail of the best postnatal care.
4. Early Prenatal Care
You must try to minimize the risk of premature birth by taking prenatal care. Micro preemies are babies born long before the due date and hence, need neonatal intensive care.
