Welcome back to The Deep Dive.

Today we are pulling a very specific volume off the shelf, Chapter 5 of Wong's Essentials of Pediatric Nursing.

And I have to be honest, when I first saw the title of this chapter, pain assessment and management.

Okay, this is going to be a quick one.

You thought it was going to be straightforward.

Well, yeah.

I mean, the equation seems simple in my head.

Patient cries, patient hurts, nurse gives medicine, and you know, everyone is happy.

Right.

But as I started reading through the source material, I realized that in pediatrics that that linear equation basically falls apart immediately.

It completely falls apart.

And that's actually a really dangerous assumption to make.

Oh.

If you walk into a pediatric unit thinking pain is simple, you are going to miss things.

And in this context, missing things means leaving a child in agony.

Right.

Because we aren't talking about adults who can press a call light and articulate, I have a throbbing pain in my lower left quadrant.

Not at all.

We are talking about toddlers who think a shot is punishment for not eating their broccoli.

We're talking about non -verbal kids.

And we're talking about premature neonates whose nervous systems are essentially still under construction.

That is exactly the landscape we are navigating.

So the mission for this deep dive is to take that simple concept of pain and unpack the actual physiology and, you know, the nursing science behind it.

OK, we need to move you from just asking, does it hurt to understanding how to measure pain when the patient is silent and then how to treat it using both the medicine cabinet and what I like to call the

Before we even get to the how, the text makes a really aggressive point about the why.

I think there's a historical context here, right?

Didn't we used to think babies didn't feel pain?

We did.

And it wasn't that long ago.

There was a prevailing myth that because an infant's nervous system was immature, they didn't perceive pain the way we do or that they wouldn't remember it.

So it didn't matter.

Wow.

The text makes it clear that was dangerously wrong.

So it's not just about being nice.

No, it's a core safety competency.

Untreated pain causes physiological chaos.

It spikes intracranial pressure.

It drops oxygen saturation and increases heart rate.

OK, but the heavy hitter in this chapter is neurodevelopment.

The text explains that pain actually alters the architecture of a child's brain.

It changes how the spinal cord processes sensation.

We are definitely going to circle back to that later.

The idea wind up because that blew my mind.

It's huge.

But let's start at the bedside.

The chapter calls the assessment phase the detective work because pain is subjective.

The definition is pain is whatever the experiencing person says it is.

That is the gold standard self -report, which is great.

But again, if your patient is six months old, self -report is off the table.

You can't just guess.

So the text lays out a comprehensive approach.

It's not just looking.

It's history, observation and physiological checks.

And you have to pick the right tool.

You can't use a hammer to turn If you have a patient who cannot speak, whether they are an infant or a toddler, you need the FLACC scale.

Table five point one.

This seems to be the one every nursing student memorizes.

FLACC.

Let's break this down, because some of these categories feel a bit subjective to me.

It tries to remove the subjectivity.

You score five categories from zero to two.

Face, legs, activity, cry, consolability.

OK, face seems easy.

Smiling is A zero is relaxed legs.

A two is kicking or specifically legs that are drawn up tight to the chest.

That fetal tuck is a classic primal pain response.

Got it.

And consolability, because babies cry for everything.

Wet diapers, hunger, boredom.

How do I know it's pain?

That's why this category is so useful.

If a baby is crying because they are bored, and you pick them up and rock them, they usually stop.

That's a score of one consolable by touching or talking.

OK.

But if you pick them up, rock them, offer a pacifier, and they are still screaming, arching their back and pushing you away, that's a two.

That inconsolability points strongly toward pain.

That makes sense.

It's a discriminator.

But here's a scenario the text brings up that confuses the FLACC scale.

Yeah.

What if the kid is in the PICU, maybe on a ventilator?

Right.

They can't cry.

They can't kick because it might be weak or sedated.

Exactly.

If you use FLACC on a paralyzed or heavily sedated child, you might get a score of zero, but they could be in ten ten pain.

So what do you do?

For those critical care situations, the text points us to the comfort scale.

It's the only one recommended for unconscious or ventilated children.

How is it different?

It looks at distress signals we often miss.

It assesses alertness and respiratory response.

Specifically, are they fighting the ventilator?

Are they agitated against the machine?

It captures that physiological distress that a behavior scale like FLACC would miss completely.

OK.

So that's the detective work for nonverbal kids.

Yeah.

Now let's graduate to the preschoolers, the ones who can talk.

This brings us to probably the most famous image in all of pediatrics.

The Wong Baker Faces Pain Rating Scale.

Table 5 .2.

You know this one.

Six cartoon faces.

It starts with a big smile for no hurt and ends with a tearful sobbing face for hurts worst.

It seems perfect.

Point to how you feel.

But the text highlights a really interesting cognitive quirk here, specifically with the smiling face.

It is a quirk, and it's rooted in child development.

Preschoolers are preoperational thinkers.

They see the world in black and white.

They often confuse pain with mood.

So I'm happy, therefore I'm not hurting.

Exactly.

A child might have a broken arm, but if their mom is holding them and they are watching cartoons, they feel happy.

So they might point to the smiling face, even though their arm throbs.

And the reverse is true, right?

Yes.

If they are scared, lonely, or just hate being in the hospital, they might point to the crying hurts worst face, even if they have no physical pain at all.

So the nurse can't just be a robot recording data.

You have to ask, is that hurting or are you scared?

Precisely.

You have to validate the choice.

Now, once they get older, usually around 8, you can drop the cartoons.

You move to the numeric rating scale, the classic 0 to 10.

The text mentions one more tool that sits in the weird middle ground.

The visual analog scale or VAS.

It's just a line, no numbers.

The VAS is tricky.

It requires abstract thinking.

You have to understand spatial relationships that here on the line means a little and here means a lot without the anchor of a number.

The text notes that most kids under 7 can't really do this reliably.

Honestly, even in practice, most nurses stick to faces or numbers.

They are just clearer.

I want to zoom in on the special investigations section of the chapter because not every patient fits these neat boxes.

True.

We have complex populations and there's one tool called the APPT adolescent pediatric pain tool that I think is brilliant.

Oh, figure 5 .3.

It's fantastic.

It's essentially a coloring book for pain assessment.

Right.

It's a body outline front and back.

You give the kid markers and you say color on this drawing exactly where you hurt and you can even say make it darker red where it hurts the most.

Why is that better than just asking where does it hurt?

Because my tummy hurts is vague.

But if a child with sickle cell disease colors in their elbows, their knees, and their lower back, you immediately see the distribution.

You can see if the pain is localized or systemic.

Plus, the APPT includes a word list where they can circle descriptors like throbbing, burning, or stabbing.

It validates their experience in a way a single number never could.

Let's pivot to the other extreme of vulnerability.

The neonates, specifically preemies.

We talked about FLACC, but the text introduces the PIPP, the premature infant pain profile.

There is a scoring mechanism here that honestly feels completely backward when you first hear it.

This is the preemie paradox.

It's a huge light bulb moment for students.

The PIPP adjusts for gestational age.

So imagine you poke the heel of a full term chunky newborn.

They scream, they turn red, they thrash, high pain score.

Makes sense.

Loud response equals big pain.

Now imagine a 28 week micro preemie.

You do the same stick.

They might just lie there.

No cry, no movement.

So zero pain.

That's the dangerous assumption.

The PIPP actually gives a higher baseline score to the younger preemie.

What?

Why?

It acknowledges that they don't have the metabolic energy to mount a crying response.

They are so depleted they can't signal you.

But because their inhibitory pathways aren't developed yet, they are likely feeling more pain than the full term baby.

That is heartbreaking.

Silence in a preemie doesn't mean comfort.

It could mean they are overwhelmed.

Exactly.

It changes how you view a quiet baby in the NICU.

What about children with cognitive impairments?

If a child is non -communicating, the text suggests the NCCPC checklist.

But the biggest takeaway there seem to be less about the checklist and more about who you trust.

You trust the parents.

This is the pain signature.

A parent of a non -communicating child is the world's leading expert on that child.

They know that a specific moan or the way the child holds their hand means pain.

Even if the nurse looks at the child and thinks they look fine, if the mom says he's hurting, you treat the pain.

Okay, so we've done the detective work.

We've used the right scale.

We know the patient's hurting.

Now we have to fix it.

Chapter 5 divides this into two toolkits, non -pharmacologic and pharmacologic.

Or, as you called it, the magic and the medicine.

And the text is pretty insistent that we shouldn't skip the magic.

This isn't just fluff to make the nurse feel nice.

Right.

No, it's physiology.

It works on the gait control theory.

If you can flood the nervous system with other input distraction, touch, cooling,

you literally block the pain signal from traveling up the spinal cord to the brain.

Let's look at distraction.

The book lists bubbles.

Now, be honest.

Is blowing bubbles actually pain management, or is it just a toy to make the kid look away?

It's legitimate pain management.

Think about the mechanics.

To blow a bubble, what do you have to do physically?

You have to push your lips, take a deep breath, and exhale slowly.

Exactly.

It forces the child into a rhythmic, diaphragmatic breathing pattern that stimulates the parasympathetic nervous system, lowers the heart rate, and lowers muscle tension.

It is a breathing exercise disguised as a toy.

So blowing the herd away is scientifically sound.

It is.

I love that.

Now, there are two things in the non -farm section that I honestly hadn't heard of before.

The J -Tip and coolant sprays.

These are game changers for needle procedures.

The J -Tip is a needle -free jet injection.

It looks like a little syringe, but instead of a needle, it uses compressed gas to shoot a mist of buffered lidocaine right through the skin pores.

So no needle at all.

Not for the numbing part.

It makes a loud pop noise, like opening a soda can, which can startle the kid, but it creates a numb wheel instantly.

You don't have to wait.

And the coolant sprays.

Things like Giebauer spray.

You spray it on the skin, and it momentarily freezes the nerve endings.

It feels cold and numb.

It buys you a window of about 60 seconds to do a stick without the child feeling the sharpness.

It's fast and effective.

And for the babies.

We can't tell them to blow bubbles.

But the text talks about sucrose.

Sweeties.

This is one of the most robustly studied interventions in the book.

Table 5 .9 breaks it down.

It's a 24 % sucrose solution.

You dip a pacifier in it or give a few drops about two minutes before a painful procedure.

How does sugar water stop pain?

It triggers the release of endogenous opioids and endorphins in the brain.

It's basically natural morphine.

It works incredibly well for neonates, but the effect is short.

So it's perfect for something quick?

Perfect for a heel stick or an immunization.

And don't forget canker root care.

Never.

Skin to skin contact.

Placing the baby directly on the parent's bare chest stabilizes heart rate, improves oxygenation, and significantly reduces crying scores.

It provides biological safety.

OK.

Bubbles, sugar, and jet injectors are great, but sometimes pain is bigger than that.

We need to open the medicine cabinet.

Section 4.

Pharmacologic management.

The text references the WHO approach.

It used to be a ladder, but now they describe it as a two -step strategy.

Right.

We've simplified it.

Step one is for mild pain.

This is your non -opioids.

Acetaminophen, Tylenol, and NSAIDs like ibuprofen.

Is there a preference between the two?

It depends on what's happening.

NSAIDs are anti -inflammatory.

So if you have bone pain or inflammation, they are superior.

But, and this is a big warning in the text oral,

NSAIDs take about 60 minutes to work.

An hour.

If you have a child screaming in acute distress, giving them an ibuprofen pill is too slow.

You need a faster plan.

Which brings us to step two.

Moderate to severe pain.

This is where we bring in the strong opioids.

Correct.

Morphine is listed as the gold standard.

Morphine is the benchmark, but we have to talk about dosing.

This is where students and honestly even new nurses get tripped up.

Pediatric dosing is weight -based, obviously.

Milligrams per kilogram.

Right.

But there is a metabolic nugget here that is totally counterintuitive.

You might assume a small child needs a tiny fraction of an adult dose.

Yeah.

And they do, in total amount.

But relative to their weight, children actually metabolize drugs faster than adults.

Really?

Why?

Think of their liver as an engine.

Relative to their total body size, a child's liver volume is large and highly active.

They burn through fuel drugs very efficiently.

So on a per kilogram basis, a six -year -old might actually need a higher dose of an opioid than a 20 -year -old to achieve the same pain relief.

So if you just scale down linearly based on size, you risk underdosing them.

Exactly.

You leave them in pain because you didn't account for their metabolic engine.

And when we talk about dosing opioids versus non -opioids, we have to understand the sealing effect.

This is a crucial safety concept.

Non -opioids, like Tylenol, have a sealing.

Once you give a certain amount,

say 15 -milligikilogy, giving more does not provide more pain relief.

It just hits a wall.

It's not hitting a wall.

If you go over the ceiling, you aren't helping the pain.

You're just poisoning the liver.

But opioids are different.

Opioids have no sealing.

If the pain is severe, you can keep titrating the dose up until the pain is gone.

The limiting factor isn't the drug's effectiveness.

It's the side effects, like sedation or respiratory depression.

But theoretically, you can keep going up.

Speaking of opioids,

there is one drug in this chapter that basically has a do not enter sign taped over it, coding.

This is the big safety alert.

Coding is effectively out of modern pediatric practice.

Which is wild to me, because I definitely remember getting coding cough syrup as a kid.

Why the change?

It comes down to genetics.

Coding is what we call a prodrug.

It's like a locked door.

The drug itself does nothing.

It has to be unlocked by the liver and turned into morphine to work.

That unlocking happens via the CYP2D6 enzyme.

And I'm guessing not everyone has the key.

Exactly.

It's a genetic lottery.

Some kids are poor metabolizers.

They lack the enzyme.

You give them coding.

It never turns into morphine and they get zero pain relief.

It's useless.

But that's not the dangerous part.

No, the dangerous part is the ultra rapid metabolizers.

Their liver has too many keys.

They take a standard dose of coding and their liver instantly dumps it all into morphine at once.

Suddenly, you have a massive overdose.

Children have died from respiratory depression after routine surgeries because of this.

Since we can't easily DNA test every kid in the ER, the safest move is to just ban codeine.

Just use morphine instead.

It's predictable.

That's a really clear explanation.

Coding is a gamble.

Morphine is a known quantity.

Now let's talk about control.

PCA patient controlled analgesia.

The pump with the button.

The text says kids can use this much younger than I expected.

Usually around five or six years old.

The criteria isn't really age.

It's developmental understanding.

Do they understand cause and effect?

I hurt, I push button, I feel better.

If they get the loop.

If they got that loop and they have the physical strengths to push the button, they can manage their own pain.

And the text distinguishes between basal and bolus.

Think of basal as the background music.

It's a continuous slow drip, keeping a steady level of medicine so the pain doesn't roar back while they sleep.

Got it.

The bolus is the volume knob, the extra boost the patient give themselves when they need to cough or move.

Before we leave the toolkit, we have to mention the creams.

EMLA versus LMX4.

This feels like a pure logistics issue for the nurse.

It is, but it's vital.

These are topical anesthetics to numb the skin before a needle stick.

But they aren't magic.

They need time.

EMLA takes 60 minutes under a dressing to work.

Which is an eternity in a busy ER.

It is.

If you put EMLA on and stick the kid 15 minutes later, you wasted your time and money, the kid will feel everything.

So what's the alternative?

LMX4, liposomal lidocaine, is faster.

It takes about 30 minutes.

Knowing which tube you have in your pocket dictates your entire workflow.

You have to plan ahead.

So we've assessed, we've treated with bubbles and morphine.

But I want to close the loop on something we teased in the beginning.

Section five asks the big question.

So what, why does all this effort matter?

Right.

You mentioned earlier that pain changes the wiring.

It does.

The text calls this the windup phenomenon.

That sounds intense.

What is actually happening in the body?

It's neuroplasticity gone wrong.

If pain is untreated, especially in those tiny preemies or neonates we talked about, the neurons in the dorsal horn of the spinal cord become hyper excitable.

They get stuck in an on position.

What does that look like clinically?

It looks like hypersensitivity.

The threshold for pain drops.

So later, a non -painful touch, like a gentle stroke or a diaper change, is perceived by that baby's nervous system as pain.

This is called alladenia.

That is terrifying.

We are training their body to feel pain where there shouldn't be any.

And box 5 .5 lists the long -term receipts.

It links untreated early pain to higher somatic complaints later in life, behavioral problems, and even learning deficits.

We are literally wiring their brains for stress.

So it's not just about the moment.

When you treat pain effectively in a neonate, you aren't just being nice.

You are protecting their future nervous system.

But on the flip side, we had the opioid crisis.

We are terrified of addiction.

The text discusses opioid stewardship.

How do we balance that?

We treat pain aggressively, but we wean responsibly.

If a child has been on opioids for more than five days, say in the ICU, their body has physically adapted.

You cannot stop cold turkey.

They will go into withdrawal.

Yes.

Trimmers, sweating, diarrhea, irritability.

The text gives us the WAT -1, the withdrawal assessment tool.

It helps nurses monitor for those specific symptoms so we can taper the drug slowly.

It ensures we don't trade one problem pain for another, which is withdrawal.

This has been a massive overview, from the FLACC scale to the CYP2D6 enzyme.

Let's recap the essentials for the listener about to start their pediatric rotation.

Sure.

Let's boil it down.

One, assessment is detective work.

Use the right tool.

FLACC for the nonverbal.

Faces for the preschoolers, but watch out for the mood confusion and numbers for the older kids.

Two, believe the patient, even if that patient is a silent preemie.

Remember, the PIPP silence can mean they are too exhausted to cry.

Not that they are comfortable.

Got it.

Three, the two -step strategy.

Tylenol NSAIDs for mild pain, morphine for severe.

Leave the coding in the history books.

And four,

use the magic.

Bubbles, sucrose, and J -tips aren't toys.

They are physiological interventions that block pain gates.

Use them every time.

And the final thought to walk away with.

I want you to go back to that wind -up phenomenon.

The next time you have to do a routine heel stick or an IV start, ask yourself, am I just collecting a lab sample or am I helping shape this child's nervous system?

If you view it through that lens, you will never skip the sucrose or the numbing cream again.

Powerful perspective.

You have the tools to be both the detective and the healer.

Thank you for listening to this deep dive into Juan's Essentials.

Go be a great nurse.
