What is transient tachypnea of the newborn? —
Transient tachypnea of the newborn, or "TTN," is a condition that causes breathing problems in newborn babies.
Babies have fluid in their lungs before birth. The fluid normally goes away when the baby is born. In some babies, the fluid does not go away as quickly as it should. This causes TTN.
A mother who has diabetes, asthma, or a cesarean birth without labor is more likely to have a baby with TTN. (A cesarean birth, or "c-section," means having surgery to get the baby out.)
What are the symptoms of TTN? —
Symptoms usually happen within 2 hours after birth. They include:
●Fast breathing, for example, more than 60 breaths a minute – This is more than 1 breath every second.
●Looking blue or gray in the face, skin, lips, fingernails, or toenails
●Hard breathing – This can include:
•Nostrils that open wide when the baby breathes in
•Skin and muscles that look like they are caving in – This can happen between the baby's ribs or under their ribcage.
•Grunting when the baby breathes out
Symptoms of TTN usually last 12 to 72 hours.
Is there a test for TTN? —
No, there is no specific test. But the doctor or nurse can often tell if a baby has TTN by doing an exam.
Other conditions can cause breathing problems similar to TTN. These include serious conditions such as pneumonia. The doctor can order a chest X-ray that shows changes in the lungs. The X-ray can help the doctor figure out if a baby has TTN or a different condition.
How is TTN treated? —
TTN usually goes away by the time a baby is 3 days old. Until then, babies with TTN are usually in the neonatal intensive care unit, or "NICU." This is a part of the hospital where doctors and nurses take care of babies who are sick or were born too early.
In the NICU, doctors can help the baby get enough oxygen and nutrition if they need it. Treatments might include:
●Extra oxygen – This helps make sure the baby has enough oxygen in their blood.
●Temperature control – This keeps the baby from getting too hot or too cold.
●Feeding tube or IV – If the baby has trouble breathing, they might not be able to nurse or drink from a bottle. A feeding tube is a small tube that goes into the baby's mouth or nose, down their throat, and into their stomach. It can be used to put breast milk or formula right into their stomach.
An IV is a thin tube that goes into a vein. It can carry a sugar mixture into the baby's bloodstream.
●Antibiotics – These are medicines to try to prevent infections or stop them if they do happen.
