Introduktion:
I don’t know about you, but in Charlotte, the kiddies have been doing a lot of coughing this winter. even though it has been unseasonably warm, those viruses have managed to get into the noses and lungs of babies with incredible ease, generating a lot of coughing and sleepless nights. I talk to parents every day in my office, who seem to be frantic to stop their children’s cough. since when did cough become enemy number one for children? Yes, it’s true, a cough makes your kids uncomfortable and means that they are sick, but, in reality, his or her cough is weapon number one preventing them from contracting pneumonia. So in today’s pedcast, I want to change your thinking about cough and have you think of this symptom as a vital protective reflex rather than a nuisance symptom keeping your child awake at night and making them miserable.
Oh, I’m sorry, I forgot to introduce myself. how rude of me. I am Dr. Paul Smolen, a board certified pediatrician with 35 years of practice and a whole lot to say. welcome to another edition of portable practical Pediatrics.
Music Intro:
Science Drive:
Long time listeners of portable practical Pediatrics know that I like to take my listeners to a fictional place I call science Dr., a place where we talk basic concepts in biology, physiology, and science. before we can have a meaningful conversation about the usefulness of cough for your child’s health, we need to review how your children’s lungs manage to stay so healthy most of the year. Let’s start with some terminology. Your child’s nose, sinuses, trachea, bronchioles and even the air sacks called alveoli are lined with cells known as epithelial cells. These cells are filled with mucous that, when your child is healthy, is slowly released and swept toward their throats by millions of beating brooms called cilia. This “River of mucous” as I call it, washes away stray bacteria, dust, and pollen that your child has inhaled and manages to get into their noses, throats, and lungs. Without this constant cleansing of their lungs by the river of mucous, every child would get pneumonia quite frequently. Remember this Doc Smo pearl, “Healthy lungs are healthy for a reason.” In other words, this protective mucous flow along with a strong cough and immune system prevents your children from clogging up their lungs with pneumonia. So now imagine that a nasty respiratory virus (like influenza and RSV) infect and damage a lot of the epithelial cells of your child’s lungs. As the epithelial cells and cilia are shed, they let go of all of their mucous and flood your child’s bronchioles with thick sticky mucous. instead of the normal trickle of mucous, the child is now faced with a tsunami of secretions. No cilia to sweep out the mucous plus buckets of mucous present this child’s lungs with a serious dilemma-how to get this stuff out of the air spaces of the lung? here is where the cough comes into play and thank goodness it does.

The Cough Dissected
A cough is an amazingly strong reflex, expelling the amount of air equal to about 3/4 of a 2 liter coke bottle with each cough, at speeds of up to 50 miles per hour. The mucous droplets in a human cough (about 3000/cough) have been found to travel several feet from the child who is coughing, and creating a noise as loud as 90 decibels! That’s a forceful, loud, and violent reflex. and it has to be to keep a child’s lungs clean during a severe viral illness. Clearing the mucous and dead cells from their lungs during a respiratory viral infection is the essential function of a child’s cough. As I said before, “Your child’s cough is the only thing standing between them and pneumonia.”
Cough Medicine, yes or No?
Now you can see that thank goodness your child has a strong cough. Without it, your children couldn’t keep their lungs free of pneumonia. giving them cough medicines that dampen this vital reflex just doesn’t make any sense. would they sleep better if you gave it to them, probably yes. would it work, maybe a little? Is it recommended by experts, definitely no. So the next time ditt barn kämpar med en otäck bröstkylning, ge dem honung, slather dem med en godkänd bröstskruv, ge dem mycket att dricka, kanske tillbringa lite tid i en ångande dusch och dra ut den luftfuktaren om du vill, men don Don ‘T Ge dem hostmedicin Kom ihåg, ditt barns hosta hjälper dem.
Varningstecken med hosta
Innan vi lämnar ämnet hosta måste jag påminna er om att det finns några situationer där en hosta kan signalera allvarliga problem. Hosta kan signalera allvarliga problem om det är förknippat med väsande andning, andnöd, andfåddhet, ansträngd andning, hög feber, bröst, rygg, nacke eller buksmärta, grymning medan du är vaken eller sover eller någon situation där ditt barn bara ser riktigt sjukt . Om du ser någon av dessa saker eller bara är orolig, av alla medel, få dem utcheckade så snart som möjligt!
