Inhaled
medications are the mainstay of therapy, and are delivered two different ways. The
first is a nebulizer, which is a machine that emits humidified air combined
with medication. The child inhales the air through a mask.
The other way to
receive inhaled medication is through "Metered Dose Inhalers." MDIs
are the puffers that most people are familiar with. Medication is sprayed
directly into the mouth, but a contraption called a "spacer" helps
make sure the medication goes directly into the lungs. Using an MDI without a
spacer leads to half of the medication missing its mark – a waste of money that
also comes with the risk of under medicating.
In general, MDIs (as opposed to nebulizers) are cheaper, more portable, and
quicker and are therefore becoming the modality of choice in pediatrics.
So what's in the
medication? The two most common groups of meds are preventative medications of
which corticosteroids are the mainstay and rescue medications of which
albuterol is the mainstay.
Inhaled
corticosteroids are used on a daily basis, whether the child has symptoms or not,
to prevent future episodes of wheezing. Think of it as sunblock for the lungs.
The child puts it on every day to prevent future troubles.
Beta-agonists are
the Aloe vera that soothes the sunburn once it happens. Albuterol is the most
commonly used beta-agonist. It works by relaxing the muscles of the airways in
the lungs, helping them open to let more air through. The effects of Albuterol are
short lived. It needs to be given again and again, usually every four hours,
until symptoms subside. The Albuterol, or aloe Vera, makes one feel better
after the burn, but does not prevent future episodes. Only sunblock, or inhaled
corticosteroids, can do that.
Some parents get
freaked out by the word "steroids," picturing pumped-up athletes
risking illegal consumption just to make their muscles bigger. Rest assured
that corticosteroids are not the same thing. Corticosteroids are similar to
steroids that already occur naturally in the body.
