Chapter 52: Concepts of Care for Patients With Inflammatory Intestinal Disorders

Welcome to Last Minute Lecture.

This free chapter overview is designed to help students review and understand key concepts.

These summaries supplement not replaced the original textbook and may not be redistributed or resold.

For complete coverage, always consult the official text.

Okay, let's face it.

When you're dealing with something like a patient whose abdomen is suddenly rock hard and their vitals are tanking, you just don't have luxury of time, right?

Yeah.

No flipping through textbooks.

Absolutely not.

You need that critical info right now, prioritized, ready to go.

Exactly.

Welcome to the deep dive.

Today, we're really cutting through the noise, getting straight to the essential care concepts for patients with inflammatory intestinal disorders.

Right.

We're tackling this pretty complex area by focusing on two main priority concepts.

First up is infection.

We see this really clearly, tragically sometimes, with peritonitis.

Which is life -threatening.

Definitely.

The second big concept is inflammation.

That's the core issue in chronic conditions like ulcerative colitis.

You quickly realize when the gut's involved, it's never just one thing, is it?

It pulls in all these other related concepts.

Nutrition, obviously.

Elimination.

Pain.

Maybe the biggest one, fluid and electrolyte balance.

Everything kind of hangs on that.

It really does.

Our mission today is pretty straightforward.

A rapid targeted analysis will kick off with the acute stuff, peritonitis, appendicitis, gastroenteritis.

We're going to focus hard on those immediate safety alerts, the critical nursing priorities you have to know.

Then we'll shift gears into the chronic side, looking at IBD, inflammatory bowel disease, really drawing those sharp lines between ulcerative colitis, UC, and Crohn's disease, CD.

All right.

Let's dive in.

Straight into that scenario everyone kind of dreads.

Peritonitis.

You mentioned it's not just inflammation.

It's like a system -wide disaster waiting to happen.

How fast does that contamination become a full -blown emergency?

Oh, it's incredibly fast because that peritoneal lining is just so vast, covering all the organs.

Peritonitis is this acute inflammation, often infection, of that normally sterile lining.

When something breaks that sterility, maybe a ruptured appendix or diverticulitis causing a perforation, bacteria flood in.

That triggers this massive, really rapid inflammatory response.

This is where that term third spacing comes in, right?

Because the fluid loss you mentioned, like seven to eight liters,

that just sounds catastrophic.

It is.

It's like pulling the plug on the whole system.

The inflammation makes the blood vessels dilate like crazy, and the capillaries become super permeable.

Fluid just pours out.

Yeah, we're talking potentially seven to eight liters a day, shifting from the bloodstream, the circulating volume - Into the abdomen.

Into the peritoneal cavity where it does absolutely no good.

It's just stuck there.

Functionally, that fluid is just gone from where it needs to be.

Exactly.

Lost to circulation, and that immediately crashes the circulating volume.

You get hypovolemic shock really fast.

Kidneys aren't getting perfused, so you risk acute kidney injury.

Electrolytes go haywire.

On top of that, peristalsis, gut movement, it slows way down or stops completely.

Now you've got these toxic contents just sitting there, potentially leading to overwhelming septicemia.

It's a deadly cascade.

Okay, so if we walk into a room and we suspect this, what are those absolute must -recognize signs, the classic cues?

The number one, most iconic finding, it's that rigid, board -like abdomen.

It feels hard as a rock.

The patient will often be lying perfectly still, maybe knees drawn up, because any movement is agony.

Guarding.

Total guarding, yeah.

Widespread pain.

You'll also probably hear diminished or completely absent bowel sounds.

High fever, definitely.

And significant tachycardia.

The heart's racing, trying to compensate for that lost volume.

So critical management.

Let's say post -op after surgery for peritonitis.

What's the absolute highest priority for the nurse?

What are we doing constantly?

Constant vigilance, basically.

Monitoring vital signs, heart rate, BP, respiratory status plus their level of consciousness, and super accurate intake and output.

This has to be done at least hourly, maybe more often initially.

And there's a really key positioning alert here.

Keep the patient in semi -fowler's position.

It's not just for comfort.

Gravity helps drain those inflammatory fluids down towards the pelvis, away from the diaphragm.

Ah, so it helps with breathing too.

Exactly.

Promotes better lung expansion, which is crucial when they're already compromised.

Okay.

Speaking of things perforating, let's shift to probably the most common reason for right lower quadrant pain.

Appendicitis.

What's the mechanism there?

Appendicitis is fundamentally an acute inflammation of the appendix.

And it usually starts with some kind of blockage.

Often it's a fecal, basically a small, hard piece of stool.

Like a little stone.

Yeah, exactly.

That blockage traps mucus and bacteria inside the appendix, pressure builds up, and it starts cutting off the blood supply.

And that's what makes it so urgent.

The tissue can become gangrenous, die off, and lead to sepsis in just like 24 to 36 hours.

Wow, that fast.

Yeah.

And the risk of it actually perforating, bursting, that climbs dramatically after about 48 hours.

So time is critical.

And we often rely on that classic pain pattern to help diagnose it, don't we?

We do.

It typically starts as this sort of vague, crampy pain, maybe around the umbilicus, the belly button area, or higher up.

Then over several hours, it shifts and localizes right to that specific spot, the McBurney point.

That's in the right lower quadrant.

But here's a tricky thing to watch for.

If the patient suddenly says the pain feels better when they bend their right hip or knee, or worse, if the intense pain suddenly just disappears.

Stuff that, right?

Not good.

That's really bad.

You have to immediately suspect perforation.

The appendix may have ruptured, relieving the pressure, but now spilling infection into the peritoneum.

That's peritonitis start.

Got it.

And the source material is super clear about things you absolutely must not do if you suspect appendicitis.

These are major safety points.

Oh, absolutely non -negotiable.

Number one, keep the patient NPO nothing by mouth.

They're likely heading for surgery, maybe emergently.

Makes sense.

Number two, do not give laxatives or enemas ever.

Increasing bowel activity or pressure could easily cause that inflamed appendix to rupture.

Big mistake.

Right.

And number three, do not apply heat to the abdomen.

Heat increases blood flow and inflammation locally, which again, seriously ups the risk of perforation.

No heating pads.

Okay.

Crucial reminders, NPO, no laxatives, enemas, no heat.

Got it.

Now, let's say the appendectomy goes smoothly, often laparoscopically these days, right?

Yeah.

Uncomplicated cases often go home the same day.

So moving on from that acute surgical issue, let's touch on gastroenteritis.

Seems less dramatic, but it can be really risky, especially for older adults.

It really can.

I mean, most cases are self -limiting, right?

Viral bug usually runs its course in about three days, but the big danger is dehydration and hypovolemia from all that vomiting and diarrhea.

Fluid loss again.

Exactly.

And specifically, we worry about losing potassium quickly hypovolemia.

That's a serious cardiac risk, especially in older folks or anyone with underlying heart issues.

And assessing dehydration in older adults can be tricky sometimes.

The signs might be different.

They can be.

You know, in younger people, you might see poor skin trigger, orthostatic hypotension, getting dizzy when they stand up.

But in older adults or those who are immunosuppressed, the first sign of dehydration might actually be acute confusion or a change in mental status.

That's often due to poor tissue perfusion, including the brain.

That's a really important point.

Confusion is a sign of dehydration.

Definitely.

Also, a helpful clue sometimes is the timing.

With gastroenteritis, the nausea and vomiting usually start before the abdominal cramping and diarrhea kick in.

That can sometimes help distinguish it.

Okay.

So management is mostly about replacing fluids or rehydration therapy, maybe IZ fluids, if it's severe.

But what about meds to stop the diarrhea, like antiparasitotics?

The book mentions being cautious with things like diphenoxalate with atropine.

Right.

Lomotil.

Yeah, you have to be careful.

Two main reasons.

First, slowing down the gut motility might actually keep the virus or bacteria in the system longer.

You're preventing the body flushing it out.

And second, particularly for older adults, these meds can cause drowsiness.

Combine that with being potentially dehydrated and weak already, and it significantly increases their fall risk.

So it's a balancing act.

You might use them short term for severe symptoms, but very cautiously.

Got it.

Okay.

We've covered those acute kind of high stake situations.

Now let's shift focus to the long haul.

Chronic inflammatory bowel diseases or IBD, specifically

ulcerative colitis, UC, and Crohn's disease, CD.

These get confused sometimes.

If you had to boil it down, what are the top say three ways to tell them apart instantly?

Okay.

Yeah.

Good question.

Think location, layers,

and complications.

That's kind of the mental shortcut.

Location, layers, complications.

Okay.

So location.

UC almost always starts in the rectum and spreads upwards continuously, but it stays only in the large intestine.

Crohn's, on the other hand, can affect any part of the GI tract from mouth to anus, but it most commonly hits the terminal ileum, the end of the small intestine.

And importantly, it's patchy.

You get disease areas next to healthy areas.

We call those skip lesions.

Okay.

So UC is continuous large bowel only.

Crohn's is patchy.

Often small bowel can be anywhere.

What about layers?

Big difference here.

UC is generally superficial.

It affects just the mucosa and submucosa, the inner layers.

Crohn's disease is transmural, meaning the information go through all layers of the bowel wall from the inside out.

And that difference in depth must explain the different complications, right?

Exactly.

Because UC is superficial, but continuous,

it's more prone to causing massive hemorrhage and a really dangerous complication called toxic mega colon, where the colon dilates massively and can perforate.

Scary.

Very.

Whereas Crohn's, being transmural and often in the small bowel leads to different problems.

Severe malnutrition due to malabsorption is huge.

And because it goes through the whole wall, it's notorious for forming fistulas.

Ah, those abnormal connections.

Yeah.

Abnormal tracts tunneling from the bowel to other places like the skin, interocutaneous, the bladder, enterovesical, or even just looping back onto other parts of the bowel, enteroenteric.

They're a major challenge.

And what about stool differences?

That UC patient has frequent, often urgent, bloody diarrhea.

We're talking 10, maybe 20 liquid stools a day.

Often with kinesmus, that feeling of needing to go even when the bowels empty.

Okay.

The Crohn's patient usually has fewer stools, maybe five or six a day.

They tend to be soft, loose, but typically non -bloody.

However, because the small bowel is often involved, you frequently see steteria, fatty, foul smelling stools because they're not absorbing fat properly.

Non -bloody, but fatty stools and Crohn's.

Yeah.

Got it.

And you mentioned surgery differences too.

Yeah.

Crohn's patients are much more likely to need surgery at some point.

Maybe 75 % of them will.

Often for complications like strictures or fistulas.

With UC, it's less common, maybe 20, 40%.

And surgery can actually be curative if they remove the entire colon.

Not usually the case with Crohn's because it can recur elsewhere.

Right.

Okay.

Let's zoom in on UC management.

For mild to moderate disease, what's the typical starting point for drug therapy?

The mainstay is a class called aminosalicylates, drugs like sulfasalazine or mesalamine.

They work as topical anti -inflammatories within the colon.

Okay.

And for flare -ups?

For flares, we often have to use glucocorticoids like pridnisone.

They're very effective at calming down acute inflammation,

but they have significant long -term side effects.

We worry about

osteoporosis, increased infection risk, blood sugar issues.

So they must be papered off as soon as possible.

Not for long -term maintenance.

Right.

Tape with the steroids.

What if drugs aren't enough and surgery is needed for UC?

You mentioned it can be curative.

What's the gold standard procedure?

It's quite complex actually.

It's called a restorative proctocollectomy with ileo pouch anal anastomosis, RPCIPAA for short.

Whoa.

Yeah.

Basically, they remove the entire colon and rectum, but they construct an internal pouch, often called a J -pouch, from the end of the small intestine, the ileum, and connect that down to the anus.

It's usually done in two stages, but the goal is for the patient to eventually be continent and avoid a permanent external bag.

That sounds amazing, but complex.

It is.

The alternative is a total proctocollectomy with a permanent ileostomy, where the colon and rectum are removed and the end of the ileum is brought out to the abdomen as a stoma.

Okay.

So if someone does have that permanent ileostomy, what's the absolute top nursing priority related to the Stoma assessment?

You have to monitor its color.

It needs to be pinkish to cherry red.

That means good blood supply.

If you see it looking pale, bluish, or dark brown -black, that's an emergency.

It means astemia, compromised blood flow, and you need to notify the surgeon immediately.

Okay.

Color is key.

What's the second thing?

Skincare.

The output from an ileostomy, the effluent is liquid or paste -like, and it's full of digestive enzymes.

It's incredibly caustic to skin.

So preventing skin breakdown around the stoma is a huge ongoing priority.

Meticulous cleaning, proper fitting appliance, skin barriers, all essential.

Got it.

Protect that skin.

Yeah.

Now let's switch over to managing Crohn's disease.

You highlighted malnutrition as a major issue.

Why is it such a central challenge in CD?

It really boils down to that common location, the terminal ileum.

That's where you absorb key nutrients like vitamin B12 and bile salts needed for fat absorption.

So when that area is inflamed or has been surgically removed, you get profound malabsorption.

Right.

Patients often end up deficient in B12, folic acid, fat -soluble vitamins.

Their albumin levels drop because they're losing protein.

So they're at really high risk for severe malnutrition, weight loss, fatigue.

During bad flares, they might even need bowel rest and nutrition given intravenously, total torrential nutrition, or TPN.

So nutritional support is paramount.

And if they develop one of those as you mentioned, does that make the nutritional needs even greater?

Oh, absolutely.

Healing a fistula requires a tremendous amount of calories and protein.

It's a huge metabolic demand.

So a major priority in fistula management, besides controlling infection and protecting the skin,

is ensuring adequate nutrition.

Often they need supplemental nutrition, maybe enteral feedings, or even TPN.

We're talking potentially 3000 calories a day or more just to support healing.

Wow.

And skin protection around a fistula must be vital too, right?

Similar to the ileostomy.

Exactly.

Especially if it's an enterocutaneous fistula draining onto the skin.

That drainage is bowel content, full of enzymes and bacteria.

It will destroy the skin if it's not managed properly with pouches, skin barriers, sometimes wound vacuum devices.

It's incredibly challenging nursing care.

Definitely sounds like it.

Okay, for Crohn's drug therapy, sometimes the standard meds aren't enough.

We move into more advanced drugs like biological response modifiers, BRMs.

What's the big safety consideration with those?

The main thing with BRMs like inflixbeb or idalamumab is that they work by suppressing parts of the immune system, which is great for reducing inflammation, but it also leaves the patient vulnerable to infections.

Makes sense.

So patient teaching is crucial.

They need to understand they're immunosuppressed, avoid crowds, especially during flu season, practice good hand hygiene, and importantly, report any sign of infection, fever, cough, sore throat, UTI symptoms immediately to their healthcare provider.

Don't wait.

Okay.

And is there a specific warning for one of those drugs, natalizumab?

Yes, there is.

Natalizumab carries a specific, rare, but very serious risk of a brain infection called progressive multifocal leukoencephalopathy, or PML.

It's deadly.

So patients on this drug need close monitoring for any new neurological symptoms, changes in thinking, vision, coordination, strength.

Any change needs immediate evaluation.

Crucial safety point.

Okay.

Let's quickly touch on a few other inflammatory conditions before we wrap up.

Diverticular disease.

We have diverticulosis and diverticulitis.

What's the main difference in how they present?

So diverticulosis is just the presence of those little pouches or diverticula in the colon wall.

Often people have them and don't even know it.

It's asymptomatic.

Diverticulitis is when one or more of those pouches becomes inflamed or infected, usually because stool or bacteria get trapped.

And the pain location is key here.

Yes.

While appendicitis is typically right lower quadrant, RLQ, diverticulitis pain is most often felt in the left lower quadrant, LOQ.

That's a pretty classic distinction, especially in Western countries where it usually affects the sigmoid colon.

Okay.

LLQ for diverticulitis.

Now the diet advice seems confusing because it flips depending on the situation.

Can you clarify that?

Yes.

This is super important for teaching.

If someone has known diverticulosis, the pouches are there, but no inflammation.

The goal is prevention.

So they need a high fiber diet, things like whole grains, fruits, vegetables, maybe supplemental fiber like psyllium.

Aiming for 25, 35 grams a day helps keep stool soft and bulky, reducing pressure in the colon.

High fiber for diverticulosis.

Right.

But UT, if they have an acute flare up of diverticulitis, active inflammation and pain, the advice completely reverses.

Now they need to rest the bowel.

So it's a low fiber diet or even clear liquids only until the inflammation calms down.

Then they slowly reintroduce fiber.

Okay.

That's a critical distinction.

High fiber for prevention, diverticulosis, low fiber during an acute attack, divertitis.

Get on it.

And any activity restrictions during diverticulitis.

Yeah.

Yes.

Similar to appendicitis, anything that increases intra -abdominal pressure is bad during an acute flare.

So advise patients to avoid lifting heavy objects, straining during bowel movements, even forceful coughing if possible.

The worry is perforation of that inflamed diverticulum.

Makes sense.

All right.

Last couple of quick hits.

Celiac disease.

What's the core issue?

Celiac disease is a chronic inflammation, but it's specifically triggered by eating gluten, a protein found in wheat, barley and rye.

It damages the lining of the small intestine.

What's the treatment is?

Purely dietary.

The only treatment is a strict lifelong gluten -free diet, GFD, no exceptions.

It's important to remember too, Celiac doesn't always present with classic GI symptoms like diarrhea.

It can show up with things like unexplained iron deficiency, anemia, osteoporosis, migraines, fatigue, skin rashes.

So keep it on the radar for those atypical symptoms too.

Good point.

And finally, parasitic infections like Giardiasis or amoebiasis.

These are typically spread through the oral fecal route, usually contaminated food or water.

Think camping, travel to certain areas, sometimes outbreaks in daycare centers.

Hand washing, by far the most effective prevention strategy.

Careful food handling and water purification when traveling or camping are also key.

Great treatment.

It involves specific anti -parasitic drugs like metronidazole for both Giardia and amoebiasis, though other drugs might use too.

And crucially, follow -up stool tests are usually needed after treatment to make absolutely sure the parasite has been eradicated.

Excellent.

Okay, that was a really packed but super focused run through of these inflammatory gut issues from the really acute emergencies to the chronic management grind.

If you had to leave our listeners with one final overarching thought, something to really stick with them from this deep dive, what would it be?

I think it's about looking beyond just the specific diagnosis label, you know, whether it's UC peritonitis, Crohn's with the fistula, severe gastroenteritis.

The ultimate bad outcomes we're trying to prevent are almost always systemic deterioration, sepsis, hypovolemic shock.

So the most critical skill is recognizing the early, often subtle signs of that deterioration, especially in older adults.

Don't wait for the textbook crashing blood pressure.

Pay attention to that new onset confusion.

Notice the tachycardia, even if the fever is only low grade, that might be your earliest clue that things are heading south systemically.

Catching those subtle changes, that's often where we make the biggest difference.

That's a fantastic point.

Focusing on those early subtle signs of systemic trouble, not just the obvious gut symptoms.

That's incredibly valuable insight.

Thank you so much for walking us through all this today.

My pleasure.

Glad to do it.

We really hope this focused look helps you apply this knowledge confidently in your practice or your studies.

Thanks for joining us on The Deep Dive, and we'll catch you next time.
