| bloodstream. "Between week 30 and
36, the baby begins to make surfactant, which lines the
air sacs of the lungs helping to keep the lungs open when
breathing out," says Dr. DiRenzo-Coffey. "If
the baby is born before surfactant is produced, the lungs
will collapse each time the baby takes a breath."
If the mother's water breaks early or she goes into
pre-term labor, the baby may begin to create surfactant
early or drugs can be given to help start the production
of surfactant before birth. "To determine if the
baby has begun production of the substance, the mother's
amniotic fluid will be tested," explains Dr. DiRenzo-Coffey.
"If surfactant is not being produced, a drug called
betamethasone may be given and an attempt to delay the
birth will me made."
Most infants will recover from Respiratory Distress
Syndrome within the first month after birth. "A
newborn with RDS will be placed under special care immediately,"
says Dr. DiRenzo-Coffey. "Specialists will continuously
monitor the baby's heart rate, breathing rate, and amount
of oxygen in the skin."
Treatment may also include:
- Laboratory tests - Blood tests and an x-ray
of the baby's chest will help to identify the cause
of the breathing problems.
- IV fluids - Because baby is using all of
his energy to breathe, an intravenous (IV) line is
used to prevent dehydration. Once the lungs have improved,
the baby can then drink milk.
- Antibiotics - The baby will be treated for
infection with antibiotics. A blood culture will then
be taken. If there is no sign of infection, the antibiotics
will be stopped in 3 days.
- Oxygen - In order to maintain a level of
oxygen within the normal range, the baby will be placed
in a plastic hood where extra oxygen is blown. Test
will be run to determine how much extra oxygen baby
needs.
Depending on the baby's condition, other treatment
may be necessary, including assisted breathing through
a ventilator or other device and the administration
of artificial surfactant.
"RDS will cause baby to be sick for approximately
3 days," says Dr. DiRenzo-Coffey. "Doctors
will know the condition is improving when the amount
of oxygen the baby requires starts to lessen. When a
baby is using a ventilator, doctors will reduce the
amount of oxygen administered until the baby can breathe
on his or her own and the breathing tube can be removed."
Once baby no longer needs oxygen and can breathe at
a normal rate, feedings can be started. "Those
who are strong and mature enough to suck, can be breast-
or bottle-fed," explains Dr. DiRenzo-Coffey. "However,
those babies whose lungs are still recovering may be
fed through a feeding tube that is passed through the
mouth and into the stomach until they are strong enough
to breast- or bottle-feed."
It is possible for short- or long-term problems to
occur from RDS, although unlikely, says Dr. DiRenzo-Coffey.
Complications may include:
- Pneumothorax - A short-term problem where
the air sacs tear and air escapes outside the lungs.
If the tear is small, no treatment is needed. If it
is large, air will be drawn out with a needle or a
tube. It can take anywhere from a few hours to a few
days for an air sacs to heal itself.
- Chronic lung disease - A potentially long-term
problem where babies with unusually severe lung disease
or those born very premature receive a lot of oxygen
and pressure from a ventilator which can scar the
lungs. Most babies will grow new lung tissue to replace
scarred tissue and will outgrow the problem within
a few months. However, during the first few years
of life, some children will have more bouts of wheezing
or pneumonia along with a cold. As the child grows
older, the problem will diminish.
"Parents
should remember that it is not common for short- or
long-term complications to result from RDS," says
Dr. DiRenzo-Coffey, "and that almost all sufferers
recovery completely and go on to live healthy, normal
lives."
