Chapter 9: Nursing Care of Women With Complications During Labor and Birth

Welcome to Last Minute Lecture.

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

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

For complete coverage, always consult the official text.

So usually, when we think about a medical procedure, we expect it to follow this highly predictable script.

Like you build the foundation, you put up the walls, add the roof.

Right, it's systematic.

Yeah, exactly, very step -by -step.

But step into a labor and delivery room,

and suddenly that blueprint turns into a live jazz performance.

Most of the time, the instruments are perfectly in tune, playing this beautiful natural symphony.

But when things go off script, when that harmony breaks down, the interventions have to be immediate.

They have to be precise and rooted in, well, split -second clinical reasoning.

Absolutely.

And that's exactly why we are focusing purely on those critical moments today.

For this deep dive, we're going through chapter 9 of Leifert's introduction to maternity and pediatric nursing, the 10th edition.

Right, the exact physiology and the nursing interventions you need when the normal, natural event of childbirth hits a roadblock.

Yeah, we want you, the listener, to really visualize yourself in that clinical space.

We know you're a nursing student gearing up to master this incredibly complex material.

So we're going to build your clinical reasoning step -by -step in the exact order of the textbook.

So your foundation is rock solid for those high -stakes emergencies.

I love that.

So let's just jump right into the deep end.

We need to look at what happens when the medical team has to step in and literally orchestrate the labor.

And right out of the gate,

we have to establish the clinical difference between induction and augmentation.

Oh, yeah.

They get thrown around interchangeably all the time.

But they are, I mean, they're completely different scenarios.

So induction is like starting the engine before it has even turned over.

You're intentionally initiating uterine contractures before they begin naturally, whereas augmentation is when the engine is running, but it's sputtering.

Right.

Labor started on its own, but it stalled out.

And you just need to give it a boost.

Exactly.

Yeah.

But before you can jumpstart that engine with an induction, you have to assess if the physical structures are actually ready to handle the stress, right?

Right.

And that's where the Bishop score comes in.

We use the Bishop score table in the text to evaluate cervical readiness.

You're assigning a numerical value based on five specific criteria.

Which are?

So you're looking at dilation, which is how far open the cervix is, then effacement, which is how thin it has become.

I always think of effacement and dilation like a thick turtleneck sweater.

Before a baby can pass through, that thick, tightly closed neck hole has to thin completely out and stretch wide open.

That is a perfect visual for the mechanics.

Along with those two, you also evaluate the consistency.

Is it firm, like the tip of your nose, or soft, like your lips?

You also note the position as it moves forward.

And finally, fetal station, which is how far down into the pelvis the baby's head has descended.

Clinically, you are looking for a total Bishop score of six or above.

So six is the magic number.

Exactly.

A score of six is your green light.

It means the cervix has ripened naturally.

If the score is lower,

giving an induction drug like oxytocin is, well, it's like pushing violently on a locked door.

Oh, wow.

Yeah, it won't dilate.

The uterus will just exhaust itself, and you dramatically increase the likelihood of an unplanned C -section.

So if the door is locked, we have to chemically pick the lock.

We have to ripen the cervix.

Yes.

We use pharmacological methods for this, specifically prostaglandins.

Like cervidil?

Exactly.

Cervidil is the most common one.

And the visual here is fascinating.

It looks almost like a tiny, flat, rectangular piece of plastic.

And it has like a string on it, right?

Yeah, a long netted withdrawal string attached to it, very much like a tampon string.

It gets placed vaginally right up against the cervix to slowly soften the tissue over several hours.

But there is a major clinical safety alert in the textbook regarding cervidil that you absolutely must internalize.

OK, what is it?

The medication is highly unstable at room temperature.

So it has to be refrigerated right up until the exact moment of insertion.

Oh, wow.

OK.

And furthermore, once you use these prostaglandins to soften the cervix, you can't just immediately hang an IV bag of oxytocin to force contractions.

The protocols require a strict waiting period.

Wait, really?

Oxytocin shouldn't be started until when?

Until at least six hours after the last dose of prostaglandins.

Wait, why the massive delay?

Like, if the cervix is soft, shouldn't we just hit the gas pedal?

You'd think so, but stacking those medications causes this compounding effect that overstimulates the uterine muscle.

The half -life of the prostaglandin has to clear out of the local tissue first.

Oh, I see.

Because if you combine them, the uterus will contract so fiercely and so frequently that it never actually rests, which completely cuts off the baby's oxygen supply.

Wow.

OK, that makes perfect sense.

So let's say the cervix is soft, it's opening, but we need to move things along physically.

The provider might perform an amniotomy, right?

An artificial rupture of membranes.

Right, AROM.

The tool they use is called an amniohook.

It looks exactly like a long, sterile plastic crochet hook.

They slide it in and snag the amniotic sac to break the water.

I always picture this as removing a waterbed cushion.

That's a great way to think of it.

Because when you remove that cushion of fluid, the hard, bony skull of the fetus drops down and presses directly against the sensitive nerve endings of the cervix.

Which kickstarts things.

Right, that intense, direct mechanical pressure triggers the body to release its own natural prostaglandins, which kickstarts much stronger contractions.

But the moment that water breaks, the nurse's assessment skills become the safety net.

Because things can go wrong fast.

Exactly.

The very first action is checking the fetal heart rate.

You have to ensure the umbilical cord didn't wash down past the baby's head with the gush of fluid.

And then we have to look at the fluid itself, right?

Clear fluid with a mild odor is what we expect.

Right, but if the fluid is yellow, cloudy, or has a foul odor, you are looking at chorioemnionitis.

Which is an infection of the amniotic sac.

Exactly, and your nursing assessment there is to immediately check the mother's temperature.

A reading of 100 .4 degrees Fahrenheit or higher confirms that suspicion.

What if the fluid is green?

If the fluid is green, that indicates the fetus has passed meconium.

Its first bowel movement.

Right, while still inside the uterus.

And the baby only does this when it is under severe physiological stress.

So green fluid is an immediate red flag for fetal distress.

It carries a massive risk for meconium aspiration syndrome when the baby takes its first breath.

Man, that's scary.

Which brings us to the ultimate labor driving medication.

Oxytocin, or commonly known as pitocin.

But, wait, oxytocin is literally the love hormone, right?

It's something our brains make naturally every day when we hug someone or bond with a baby.

So why is IV oxytocin considered a high alert medication?

Well, it's about how it's delivered.

When our brains release oxytocin naturally, it happens in perfectly timed pulsatile bursts regulated by biological feedback loops.

Okay.

But when we administer synthetic oxytocin continuously through an IV pump, we completely bypass those protective feedback loops.

So the uterus is forced to contract relentlessly.

The severe risk we are monitoring for is tachycystal.

Which means overstimulating the uterus.

Exactly.

The text defines tachycystal as more than five contractions in a 10 minute window.

Contractions that last longer than 90 seconds or resting intervals between contractions that are shorter than 60 seconds.

So they're too fast, too long, or too close together.

Right, and during a contraction, the uterine muscle clamps down so hard that it physically squeezes the blood vessels in the placenta shut.

The baby only receives fresh oxygen and nutrients during the resting phase.

Wow.

So if the uterus is constantly squeezing, you are essentially holding the baby's breath for it.

Okay, so if you're the nurse staring at the monitor and you see tachycystally, and the baby's heart rate starts dropping,

you don't wait for a doctor's order, you just act.

You have to.

You stop the oxytocin infusion immediately to cut off the fuel source.

Then you open up the plain IV fluids to physically flush the medication out of the maternal bloodstream.

Yep, and you change your position.

Right.

Flip the mother onto her side to take the heavy weight of the uterus off the major blood vessels in her abdomen.

And you slap an oxygen mask on her at eight to 10 liters per minute to supersaturate whatever blood is getting to the baby.

You are literally resuscitating that fetus in real time while it is still inside the womb.

That is just incredible.

Right.

But you know, even with all these interventions, the physical mechanics of birth can still stall out at the very end.

This is where we might see assisted births.

We're talking episiotomies, where the perineal tissue is surgically cut to widen the opening.

Or forceps.

Right, which look like, well, large curved salad tongs that gently cradle the baby's cheekbones to help guide the head out.

Or vacuum extraction.

Yeah, with vacuum extraction, a suction cup is applied directly to the baby's scalp.

The provider pulls while the mother pushes.

The negative pressure from the vacuum pulls the soft scalp tissue upward into a cone shape, which sounds terrifying.

Well, it creates a benign swelling on the baby's head called a chignon.

It looks quite alarming to the parents because the baby's head looks misshapen.

Oh, I bet.

But the nurse's job is to educate them that this is just superficial fluid and it will resolve naturally in a few days.

Good to know.

But if forceps and vacuums fail, or if the baby is in severe distress, the team pivots to a cesarean birth.

Yeah, and the clinical atmosphere changes in a heartbeat there.

Right.

The nurse is certainly managing this flurry of physical prep, inserting a Foley catheter to drain the bladder so it doesn't get nicked by the scalpel, throwing in new IV lines, prepping the surgical site.

But the emotional shift is just as heavy, isn't it?

It really is.

The patient is often terrified.

They're shivering from the adrenaline and grieving the loss of the natural birth they envisioned.

The nurse becomes the emotional anchor in that room.

Because it's so chaotic.

Exactly.

You're explaining every single step as you race down the hallway to the operating room, ensuring the partner is scrubbed in, and just maintaining a sense of controlled calm.

So crucial.

Let's shift gears a bit.

We've explored what happens when the medical team intervenes, but what happens when the natural mechanics of labor simply fail on their own?

Ah, dystocia.

Right.

The textbook categorizes these natural roadblocks by the four Ps.

Powers, passenger, passage, and psyche.

Let's start with the powers.

The uterine contractions themselves.

They can malfunction in two entirely different ways,

right?

Hypertonic and hypotonic labor.

Yes, and the text contrasts these clearly.

Hypertonic labor occurs very early in the process, during the latent phase.

The uterine muscles fire off rapidly, but they're completely uncoordinated.

They just spasm.

Right, they don't start at the top of the uterus and sweep downward smoothly.

The contractions are agonizingly painful for the mother, but because they are uncoordinated, they do absolutely nothing to dilate the cervix.

So it's all pain, no progress.

Exactly.

The uterus never fully relaxes, so the muscle becomes severely fatigued.

The intervention here is shutting the system down.

We provide rest.

We administer mild sedation or even a tocolytic drug to paralyze the contractions temporarily, allowing that exhausted muscle to recover.

Okay, so that's hypertonic.

Hypertonic labor is the exact opposite.

This happens later in the active phase of labor.

The contractions start out strong and coordinated, but then the muscle just runs out of steam.

Right, they just fizzle out.

Yeah, they become weak and spaced apart.

So for hypotonic labor, the treatment is simulation.

We hit the patient walking, we break the amniotic water to remove the cushion, or we hang that IV oxytocin to whip the muscle back into shape.

Spot on.

Moving to the second P, the passenger, the fetus itself.

Sometimes the baby's just too big.

Yes.

Macrosomia is defined as a fetus weighing more than 4 ,000 grams.

That's roughly 8 .8 pounds.

And the terrifying mechanical emergency associated with macrosomia is shoulder dystocia.

Oh man, this one is wild.

It is.

The baby's head delivers normally, but the broad shoulders get wedged tightly behind the mother's rigid pubic bone.

The baby's head is out, but its chest is compressed inside the birth canal, meaning it literally cannot expand its lungs to breathe.

So the nurse has to jump into action using very specific physics here.

You have to apply suprapubic pressure.

You stand on a stool, lock your arms, and press your fist firmly downward and backward right above the mother's pubic bone.

Not on the fundus.

Right.

You are physically trying to fold the baby's shoulder inward like a taco, collapsing it down so it can slide under the mother's pelvic bone.

But like you said, you must never apply fundal pressure.

Never.

If you push on the top of the uterus, the fundus, you are just violently ramming that wedged shoulder deeper into the maternal bone that will permanently tear the brachial plexus nerves in the baby's neck or literally rupture the mother's uterus.

That's terrifying.

It is.

And even with correct suprapubic pressure, the physical force required to dislodge the baby is immense.

So after a shoulder dystocia birth, the nurse must palpate the infant's collarbones.

You are feeling for crepitus.

Like a crunchy popping sensation under the skin.

Exactly.

Which indicates the clavicles snapped under the pressure.

Okay, so that's size.

But sometimes the passenger isn't too big.

They're just facing the wrong way.

Occipit posterior or OP position.

The baby is facing forward instead of backward.

Right.

So the hard back of the baby's skull grinds directly against the mother's spine with every single contraction.

Causing just blinding back labor.

Yes.

So we use gravity and biomechanics to fix this.

We get the laboring patient onto their hands and knees.

Think of the uterus like a hammock.

When you're on your hands and knees, the hammock hangs downward.

Gravity pulls the heavy back of the baby's head away from the mother's spine.

So it relieves the pain instantly.

Yep.

And gives the baby physical space to rotate internally.

The textbook also shows visuals of lunging or using a peanut ball between the mother's legs when she's lying on her side.

Oh right, the peanut ball.

Yeah, the shape of the ball physically opens the pelvic outlet, shifting the bony dimensions just enough to let the baby turn.

Which perfectly bridges us to the passage.

We think of the passage as, you know, the rigid, unchangeable bones of the pelvis.

But the most common roadblock isn't bone at all.

No, it's not.

It's soft tissue.

What is literally standing in the way most of the time.

A full bladder, a distended bladder.

Really?

Yes, anatomically, the bladder sits right in front of the lower portion of the uterus.

If it fills with urine, it inflates like a balloon and creates a physical wedge that blocks the baby's head from dropping down into the birth canal.

A full bladder will completely stall a perfectly healthy labor.

That is wild.

So the simple, crucial nursing action is ensuring the patient voids every one to two hours.

If they have an epidural, they can't feel the sensation of a full bladder, so the nurse must regularly perform straight catheterizations to keep that physical pathway clear.

It's incredible that a full bladder can just stop a baby.

And speaking of invisible forces that stall labor, we arrive at the final P, the psyche.

We always say stress is bad for labor, but the physiological mechanism is crazy.

It really is.

When a patient feels unsupported, terrified, or lacks privacy, their brain triggers a massive fight or flight response.

The adrenal glands dump epinephrine into the bloodstream.

Which is a survival hormone.

It physically constricts the blood vessels feeding the uterus, diverting that oxygen -rich blood away from the baby and sending it to the mother's skeletal muscles so she can run away from danger.

And it steals glucose, doesn't it?

Yes.

The stress response literally steals circulating glucose.

The uterine muscle is working harder than a marathon runner.

It desperately needs glucose for ATP energy.

But the stress response starves the uterus of energy and blood, chemically bringing labor to a grinding halt.

Wow.

Okay, so now that we understand the mechanics, let's talk about the clock.

Because timing is everything.

We have two extremes here.

Precipitate labor and prolonged labor.

Precipitate labor is lightning fast.

The entire process from the first contraction to holding the baby is over in under three hours.

It sounds like a dream scenario, honestly.

Right.

But the text says the extreme violent force of those rapid contractions carries a massive risk.

The maternal tissues don't have time to stretch, so they tear deeply.

And the baby's head is being slammed against the pelvic floor, leading to cerebral trauma and bruising.

It's too much, too fast.

On the opposite end, we track prolonged labor using a Friedman curve, plotting the hours against the centimeters of cervical dilation.

And what's the big risk there?

Well, prolonged labor exhausts the mother's physical reserves, but the primary danger is infection.

Once the amniotic sac ruptures, the sterile environment of the uterus is exposed to vaginal flora.

The longer the labor drags on, the higher the risk that bacteria will ascend and cause a life -threatening infection for both of them.

Which highlights the importance of knowing exactly when the water breaks.

We deal with PROM, premature rupture of membranes, and PPROM, premature rupture of membranes.

The difference is just gestation, right?

Exactly.

PROM is when the water breaks before contractions start, but the baby is full term.

PPROM is when the water breaks before 37 weeks.

Okay, so when a patient walks into triage and says,

uh, I think my water broke, but maybe I just peed.

How do we definitively know?

We rely on chemistry for that.

The normal vaginal environment is highly acidic, which helps kill off bacteria.

Amniotic fluid, however, is alkaline.

So we swab the fluid with a strip of yellow nitrosine paper.

Oh, right, the nitrosine test.

Yeah, if the fluid is alkaline amniotic fluid, the pH shift causes the paper to instantly turn a dark navy blue.

So once you see that blue paper, the protective barrier is officially gone.

Your nursing education kicks in immediately, you teach the patient, nothing goes inside the vagina, no intercourse, no unnecessary cervical checks.

Right, and you monitor maternal temperature constantly and have the mother aggressively count fetal kicks to ensure the baby isn't in distress.

Got it.

Now, if they are preterm, meaning they're between 20 and 37 weeks pregnant, we don't just wait, we actively try to stop the labor.

The heavy hitter for tocolytic therapy is magnesium sulfate.

But wait, isn't magnesium sulfate used for other things?

Like it's a central nervous system depressant.

We use it to stop seizures in patients with preeclampsia.

How does an anti -seizure medication stop uterine contractions?

It all comes down to cellular function.

Muscle fibers need calcium to contract.

Magnesium sulfate acts as a calcium antagonist.

It essentially blocks the calcium channels in smooth muscle tissue.

And the uterus is a smooth muscle.

The largest smooth muscle in the human body,

actually.

So the magnesium floods the tissue and completely relaxes it.

By paralyzing the uterus, we buy the medical team two to seven precious days.

Which gives them time to administer steroid injections to the mother, which rapidly accelerate the development of the premature baby's lungs.

Exactly.

But because it's a depressant, the side effects are systemic.

The nurse has to watch the patient like a hawk.

Because you're relaxing muscle tissue everywhere.

Right, so you have to ensure you aren't relaxing the respiratory muscles to the point of respiratory failure.

You are constantly assessing the patient's respiratory rate.

You also use a reflex hammer to check their deep tendon reflexes.

Like the knee -jerk response.

Yes, the reflexes will disappear right before the respiratory drive shuts down, serving as an early warning system.

And because toxicity can happen rapidly, you must always have the chemical antidote drawn up in a syringe and sitting at the bedside.

Which is calcium gluconate.

Exactly.

Okay, so that's the danger of a baby coming too early.

But what happens when the baby stays in too long?

Prolonged pregnancy goes past 41 or 42 weeks.

We tend to think, great, the baby's just getting bigger and stronger, but the textbook outlines a very different reality.

Yeah, the placenta is an organ with a hardwired expiration date.

It physically begins to age and calcify.

The vascular network inside it degrades.

It stops filtering toxins efficiently, and it simply stops delivering a robust supply of oxygen and nutrients.

So the baby is starving in utero.

Sadly, yes.

It actually begins burning its own fat stores.

The baby loses weight, their skin becomes dry, cracked, and peeling, because the amniotic fluid volume drops.

Furthermore, the physiological stress of hypoxia relaxes the baby's anal sphincter, drastically increasing the risk of passing meconium into that fading fluid.

And once that post -term baby is finally born, they are at a massive risk for severe hypoglycemia.

Because their nutrient supply line was failing for weeks,

they have absolutely no glucose reserves left to handle the shock of life outside the womb.

Right, it's like the grocery store closed its doors while they were still inside.

Man.

Okay, so we've built a foundation, covered the stalls, the tining.

Now it's time to apply it to code blue obstetrics, the sudden life -threatening emergencies where nursing actions save lives in seconds.

Let's start with a prolapsed umbilical cord.

A true emergency.

Yeah, I compare this to stepping on a diver's oxygen hose.

The cord falls below the presenting part, and the baby's heavy bony head drops down onto that soft cord and pins it against the mother's rigid pelvic bone.

The baby cuts off its own blood supply.

Exactly, they are suffocating.

The textbook has a diagram showing the exact nursing intervention for this.

If you are performing a vaginal exam and your fingers feel a pulsating cord ahead of the baby's head, you do not remove your hand.

You leave it in?

You must.

You push your gloved fingers upward directly against the baby's skull, and you physically lift the fetal head off the cord.

You hold the weight of that baby's head up to keep the oxygen flowing.

And you just hold it there, you do not let go.

You hold your hand inside the patient while they roll her down the hall, and you don't let go until the surgeon cuts into the uterus and lifts the baby out from above.

That is wild.

Simultaneously, you must immediately place the mother in a knee chest position or drop the head of the bed into the Trendelenburg position.

Head down, pelvis elevated.

Right, to let gravity help pull the heavy fetus back up into the fundus of the uterus away from the pelvic floor.

That is true frontline nursing.

Another massive emergency revolves around abnormal placental attachment.

The placenta is supposed to attach to the superficial lining of the uterus and peel off cleanly.

But sometimes it roots too deeply.

We have placenta accreta, increta, and procreta.

The Latin prefixes tell you exactly how deep the invasion goes.

Accreta means the placenta has attached abnormally deep into the uterine lining.

Increta means the placental villi have grown completely into the uterine muscle layer.

And procreta.

Procreta means the placenta has grown entirely through the uterine wall and sometimes attaches to surrounding organs like the bladder.

But the actual crisis doesn't happen until after the baby is born, right?

Correct.

Normally after the baby delivers, the placenta detaches and the uterine muscle violently clamps down.

That clamping acts as a biological tourniquet to pinch off the massive blood vessels and stop the bleeding.

Oh, but if the placenta is cemented into the muscle.

It refuses to detach.

When the provider attempts to manually remove it or if it partially tears away, the bleeding is catastrophic.

The uterus physically cannot clamp down around the retained tissue.

The hemorrhage is so rapid that the only way to save the mother's life is often an immediate emergency hysterectomy right there on the table.

Good grief.

And speaking of the uterus tearing,

we have uterine rupture.

This is a severe risk for VBAC patients, right?

Vaginal birth after cesarean.

Yes.

The uterus has an old surgical scar on it from the previous C -section.

That scar tissue doesn't stretch like normal muscle.

Under the immense crushing pressure of active labor contractions, that weak point can suddenly tear completely open.

And the clinical signs in the textbook are just terrifying.

You see a sudden change in vital signs.

Her heart rate spikes.

Blood pressure plummets as she hemorrhages internally.

She'll suddenly complain of pain right between her shoulder blades.

Which is referred pain from the internal bleeding irritating her diaphragm.

Exactly.

And most tragically, you'll see a sudden loss of fetal heart tones because the placenta has sheared away.

It's devastating.

And our final emergency is amniotic fluid embolism or anaphylactoid syndrome.

It's incredibly rare, but highly fatal.

This happens when amniotic fluid, which is thick with vernix and fluid and debris, somehow breaches the placental barrier and enters the mother's central bloodstream.

And it causes immediate hypotension and respiratory distress, right?

Yes.

It acts as a mechanical obstruction in the lungs, like a pulmonary embolism, and triggers a catastrophic immune response at the same time.

The nurse's role is initiating basic life support, pushing 100 % oxygen and assisting with aggressive resuscitation.

It is all so intense.

We spent an immense amount of time studying the physical mechanics here, but I wanna leave you with a provocative final thought.

The textbook points out something profound.

The medical team views a resolved shoulder discosia or an emergency C -section as a successful delivery because both patients survived physically.

But the psychological trauma of a prolonged labor or an emergency C -section or a precipitate birth, it lingers.

The textbook explicitly notes that.

Yeah.

The nurse's role isn't just saving the physical life in the room, it's protecting the mother's mental health for her next pregnancy by communicating and being present in that chaos.

You are the calm in the center of their storm.

Exactly.

And with the deep physiological understanding you're building right now, you're gonna be incredibly prepared for those critical moments.

So thank you so much for studying with The Last Minute Lecture Team today.

Good luck on your exams and your future nursing career.

You've got this.
