Hey everyone, it's Sara with RegisteredNurseRN.com and in this video I'm going to be doing an NCLEX
-
review over GERD. And this video is part of an NCLEX review series over the GI system,
-
so be sure to check out those other videos. And as always in the YouTube description below or at
-
the end of this video you can access the free review quiz that will test you on GERD. So let's
-
get started. So what is GERD? GERD stands for gastroesophageal reflux disease. And based on
-
this long name we know that we're dealing with the stomach which is gastro and the esophagus
-
which is esophageal. And GERD is a chronic condition where stomach contents is flowing
-
back into the esophagus. So in your stomach you eat food you have acid and enzymes and it's just
-
going back up through the esophagus. And the cells that line the esophagus are not made to withstand
-
acidic conditions so they start to become really irritated. Now why does this happen? This usually
-
happens due to a weak or damaged lower esophageal sphincter which we'll refer to as LES. Now GERD
-
is sometimes referred to as acid reflux disease. So if you hear someone say I have acid reflux
-
disease they mean this as well. And one thing you want to keep in mind is that some people
-
have random episodes of acid reflux and then it goes away. Now it's termed GERD when the acid
-
reflux tends to occur twice a week or more on a regular basis. So it's a chronic condition
-
that's been happening over time. And if a patient has this they have GERD acid reflux over a long
-
period of time they need to go to their physician who needs to look at that maybe prescribe some
-
medicines because this disease can cause some long-term complications. Now let's look at the
-
normal physiology of swallowing food. What happens when we chew our food and swallow it in someone
-
who doesn't have GERD? Because we know with GERD whenever the patient is swallowing their food and
-
it enters into the stomach it is getting back into the esophagus due to a weak lower esophageal
-
sphincter. So before we dive into the patho let's see what our body should do normally. Okay so we
-
chew our food digestion starts in the mouth and we swallow it. Now that food is squeezed down
-
through the esophagus and the esophagus is made up of smooth muscles that help guide that food
-
down to the stomach and that's called peristalsis. Now whenever that happens your lower esophageal
-
sphincter relaxes and it allows that food to go into the stomach. Now after it relaxes
-
it closes and it closes very tightly because it doesn't want any of that contents the acid
-
the enzymes the food to go back up through that esophagus. So that is what will happen to someone
-
who doesn't have GERD. Now with someone who has GERD what is happening is that we are having
-
issues with the following things. We're having issues with our esophagus our lower esophageal
-
sphincter our esophageal mucosal lining and the stomach acid and the food contents. So let's take
-
a look at what's going on with esophagus and GERD. Okay we learn that the esophagus squeezes food in
-
wave-like contractions and works with that lower esophageal sphincter which relaxes to let food in.
-
Well sometimes what can happen with the esophagus is that it can have impaired motility and it will
-
cause the lower esophageal sphincter to close at irregular times which can lead to GERD because
-
that acid is back flowing up through the esophagus and the LES is closing at irregular intervals and
-
it's allowing that acid to get into the esophagus and erode it and form ulcers. Now let's look at
-
LES lower esophageal sphincter. Now this is it's right here it's a collection of circular muscles
-
at the end of your esophagus and it opens and closes and when it closes it's supposed to be a
-
really nice tight seal so nothing can back up in there. Well with GERD we learned earlier that it
-
can become weak and why does it become weak? Well if it has some increased pressure on it it can
-
damage it and make it weak over time or medications or other chemicals can damage it and
-
make it not close as tightly. So let's talk about some things that can cause increased pressure on
-
the LES. Pregnancy, as that baby grows it pushes up on this diaphragm and the diaphragm is very
-
close to your stomach and your esophagus puts pressure on there which in turn will put pressure
-
on the LES because it's not closed properly and you get acid reflux. Obesity, same principle
-
overeating, eating too much food. If you eat a really huge meal put all that food into your
-
stomach and it will increase pressure upward onto the LES cause it to leak the gastric fluid into
-
your esophagus and a hiatal hernia. Let's talk a little bit about hiatal hernia. What is it?
-
Okay what happens is that the stomach is supposed to be below the diaphragm. Now with a hiatal
-
hernia the top part of the stomach has herniated through a weak part in the diaphragm. The diaphragm
-
is the blue area and it's just herniated up through there and what can happen is that gastric
-
acids and foods can just pull in there and it's very close proximity to the lower esophageal
-
sphincter which is going to cause a lot of pressure on that and mess it up and won't close
-
properly so a hiatal hernia can cause it. Now medications or some types of chemicals, antihistamines
-
can weaken your lower esophageal sphincter, calcium channel blockers, sedatives, smoking,
-
and certain foods which we'll really get into the diet teaching but just to list some like
-
fat and greasy foods, peppermint, spearmint, any of those type things can weaken that LES and
-
that's why you tell the patients to avoid consuming them or limit the consumption of them.
-
Another thing that can cause GERD is delayed gastric emptying and what's happened is that
-
the stomach isn't emptying its contents through the small intestine like it should instead it's
-
staying in there too long that increases pressure on the LES and can weaken it and some drugs that
-
can do that are anticholinergic so you really want to watch out for your patients who are taking
-
those medications. Next esophageal mucosal lining what happens to that is that the cells that line
-
your esophagus start to erode and they become inflamed because they're not made to be in contact
-
with all those acids and enzymes so the person can develop a condition called esophagitis
-
and due to that chronic inflammation irritating those cells there is an increased risk of
-
esophageal cancer. Also some other things that can happen with esophagus are these other complications
-
due to all that chronic inflammation they can get strictures and where you have narrowing of
-
the esophagus just from all that chronic inflammation causing scar tissue to build up over
-
time and it will narrow it. Another thing is that they can develop what's called Barrett's esophagus
-
and this is a very interesting disease and what happens is that the lining of the esophagus that
-
was normally there starts to change and it will actually match the cell lining that is found in
-
the intestine and because of that the patient is at risk for a rare form of cancer so it's very
-
interesting that it can do that. Another thing they can have bleeding as well. Next key player
-
is the stomach acid like the hydrochloric acid and pepsin and the food contents and again when
-
they do they just get up there in that esophagus and they erode those cells and that lining
-
and what can happen is that this acid not only can go past the lower esophageal sphincter it can
-
go up all the way past the upper esophageal sphincter and what's past that is your pharynx
-
up through your ear canals and then in front of that a little bit in front of your pharynx
-
is your respiratory system so that acid can really get in there and cause some problems
-
and whenever it does that it's referred to as laryngopharyngeal reflux and GERD can lead to
-
this so just think about it if the acid goes up into the pharynx what do we have up there we have
-
our throat we have our ears so we can get some ear infections it can even go down into the windpipe
-
where we can get some pneumonia lung infections also can aggravate the patient's signs and
-
symptoms if they have asthma they can have coughing and even voice changes like their voice
-
sounds hoarse from where that acid is just going up where the voice box is where everything's at
-
and just wearing that away and causes them to have this hoarse sounding voice now let's look
-
at the signs and symptoms that you may hear your patient report to you who has possibly GERD okay
-
the most common thing that patients will report is heartburn and this is like a burning sensation
-
in the chest it can even be so painful that the patient may confuse it as that they're having a
-
heart attack so they may need a cardiac workup as well just to ensure that that isn't what it is
-
or it's GERD another thing they can complain of is epigastric pain having stomach pain
-
regurgitation and this is where the acid contents is going up in through the throat they may report
-
like a bitter taste in their mouth or whenever they're laying down in a prone position they can
-
feel that food coming up as well another thing is a dry cough which tends to be worse at night when
-
they're lying down sleeping as that acid is coming up through that esophagus and they start to get
-
choked on it and they cough or they may have a cough throughout the day a nausea problem swallowing
-
a lot of patients i've had report just feels like there's a lump in my throat and that could be
-
again possibly from the erosion or regurgitation the acid coming up another thing is that they may
-
have recurrent lung infections and ear infections and we learned about in the patho why that is
-
now not all patients will report heartburn um some patients don't even have that typical
-
indigestion type pain they just may have that chronic coughing the voice changes where their
-
voice is hoarse or um ear infections so may want to look further into that see what it is
-
now how is GERD diagnosed as the nurse you need to be familiar with the names of these tests so
-
you can be able to tell your patient what they're going to be doing because a lot of times patients
-
are like hey i'm going for this test what is it and you'll have to talk to them about it or just
-
explain what to expect okay um one way to diagnose GERD is an endoscopy where they take a scope they
-
look down through the esophagus and they can assess the esophagus for any changes like narrowing
-
ulcers erosions things like that another test is esophageal manometry and this is where they assess
-
the function of the esophagus's ability to squeeze that food down into the stomach and how that lower
-
esophageal sphincter is closing so that can assess that another test is ph monitoring and this is
-
where they put in a small tube and the patient will have it in there for about 24 hours and
-
they'll just go on about their activities of daily living and the tube will measure the amount of
-
acid that comes in contact with the esophagus and that can help them see if they have GERD now what
-
are the treatments for GERD we're really going to hit on this and the nursing interventions and diet
-
and we're going to go over the medications in depth but let's see what the in a nutshell what
-
the treatment is um lifestyle changes such as losing weight um because obesity can cause this
-
changing your diet the foods that you eat quit smoking things like that medications and um in
-
the most severe cases they can have a surgery called fundoplication and this is where the
-
where the fundus of the stomach is placed around the lower part of the esophagus so in a sense it
-
helps strengthen it helps to strengthen the lower esophageal sphincter now let's talk about the
-
nursing interventions what are you going to do for a patient who has GERD or you suspect has GERD
-
okay one thing we're going to do is we're going to assess we're going to assess the patient's
-
frequency and quality of pain because a lot of times patients may say oh my reflux is just acting
-
up and in reality they may be having a myocardial infarction um a heart attack so you want to be
-
able to differentiate between those two um another thing is you want to assess them for other signs
-
and symptoms that's not the most obvious to GERD like that heartburn and indigestion you want to
-
look at the respiratory system um are they having chronic bouts of pneumonia or is their asthma
-
really flaring up or are they aspirating a lot where the regurgitation is happening that food's
-
coming up and it's going into the lungs and some signs and symptoms of aspiration or coughing
-
decreased oxygen saturations if their SATs were good then all of a sudden
-
they're down abnormal lung sounds and increased increased respiratory rate
-
um actually had a patient who did this um they were there going to be having surgery um they
-
were really mobile they could get up do things for themselves and they had just ate breakfast about
-
an hour after breakfast they had laid down to take a nap um and they had aspirated their food
-
where they were having regurgitation and um their SATs were like 97 98 98 percent throughout the
-
whole day and then all of a sudden they were dropping down in the 80s they're having chronic
-
coughing and they were having voice changes where um they were really hoarse and um their
-
respiratory rate was really high and uh we did a test x-ray and it showed that they had aspirated
-
some of that breakfast um from earlier and they had severe GERD so um can't happen another thing
-
is that uh you need to watch out for those voice changes and a chronic cough that tends to get
-
worse when they're lying down okay another thing is their pain ask them is aggravated after you
-
eat a heavy meal and ask them the foods that make it worse and help them develop a diet
-
to um substitute some other foods that they can incorporate instead of eating those foods that
-
make their GERD worse then you want to look at their medication history what meds are they
-
taking because we learned that certain meds can cause the LES to relax like antihistamines
-
calcium channel blockers and do they smoke as well that can affect that and anti-cholinergics
-
they decrease gastric emptying then you want to educate them so what you want to educate them
-
about mainly is a lot of food stuff because this is what's causing our problems our food so um you
-
want to educate them to eat small meals avoid really just filling up on these really large
-
meals because it's put a lot of pressure in the stomach and then in the end it's going to put a
-
lot of pressure on that lower esophageal sphincter and they need to avoid foods that relax the lower
-
esophageal sphincter like greasy fatty foods alcohol coffee peppermint or spearmint and watch
-
soft drinks because all that carbonation once you ingest those increases pressure in the stomach
-
and increases pressure on the LES another thing is that they want to make their last meal about
-
three hours before bedtime to decrease the chances of regurgitation because when they eat a meal they
-
lay down on their back that puts a lot of pressure on the lower esophageal sphincter
-
and it can cause some reflux then they want to sit up one hour after meals um if they're obese
-
they need weight loss because that puts a lot of pressure on the sphincter smoking cessation
-
and watch acidic foods especially if they have erosion in the esophagus um foods like tomatoes
-
or citrus fruits and juices can really irritate that esophagus even more and then plus if they're
-
having regurgitation where this contents is back flown it's just going to go from the stomach and
-
back into the esophagus so they need to watch those foods as well now let's look at the medications
-
ordered for patients who have GERD as the nurse you want to be familiar with these drug categories
-
and what they do okay so um first type the patients take are called antacids and what
-
antacids do is that they neutralize that acid so it's not as acidic whenever it back flows into the
-
esophagus and won't erode it as much um some drugs that are antacid are like magnesium hydroxide or
-
calcium carbonate and you give these to the patient they chew them and then they swallow them
-
um the one thing you need to remember about antacids is that they interfere with a lot of
-
drugs so it's best to give them alone and if you have to give like an h2 blocker because sometimes
-
patients are on histamine receptor blockers and you'll want to weigh about an hour to two hours
-
before you give um it if they've had an antacid along with if they're taking antibiotics or
-
carafate like your po antibiotics because it can interfere with absorption of the drugs
-
okay another group of category drugs ordered are histamine receptor blockers and these drugs work
-
by blocking the histamine and it causes the products product cells to decrease their projection
-
of hydrochloric acid which decreases gastric acid um some popular drugs are like rinitidine also
-
called xan xantac or famopidine also known as pepsin now these drugs are typically used short
-
term and a patient takes them as symptoms present like prm and again you don't give them with
-
antacids wait about hour or two before you give them because it can interfere with how they work
-
okay other drugs proton pump inhibitors ppis um some popular drugs that are ppis are like
-
omeprazole like prilosec or protanazole like protonics and these decrease stomach acid
-
and help the esophagus heal now one thing about ppis is that they will use them long term but
-
long term usage of ppis increases a patient's risk of bone fractures so watch out for that
-
and assess your patient for that now how ppis work is that they attach to the proton pump
-
of the parietal cells so your hydrogen and your potassium that's your proton pump however it
-
blocks the release of hydrogen so it can't mix with those chloride ions which would make
-
hydrochloric acid hcl so it's not formed so it'll decrease the stomach acid another group of drugs
-
used are called prokinetics and these work by preventing delayed gastric emptying by improving
-
the lower esophageal pressure and improves peristalsis so they have like a cholinergic
-
effect because remember our anti-cholinergics cause delayed gastric emptying and some drugs
-
that are considered prokinetics are bethanocoll or metroclopramide also called
-
reglan okay so that wraps up our lecture on GERD thank you so much for watching don't
