No One Likes A Purple Baby

You can’t always tell a “bad” baby by the fetal heart strip.

That is to say, some babies look fantastic during labor and all the way through pushing, but when kiddo is born and the big moment comes, they just can’t seem to get the hang of “life on the outside”.

The majority of babies transition well.  When L&D nurses talk about babies “transitioning”, we mean the process that takes place immediately after birth where baby goes from being in-utero and fully dependent on mom’s body to breathe, feed, and remove waste to suddenly having to do all of that for himself.

Like I said, most babies figure it out on their own within moments of being born.  They take a surprised breath, and with a bit of drying and physical stimulation, they start to cry, their skin turns pink, and wa la!  Life doesn’t really begin as much as it just continues.

Still, my hospital requires that at all births, there is a nurse present for mom and a second nurse present for baby.  This ensures that if there is an emergency with either, both have their own dedicated staff member present and fully in-tune with their history and their treatment. The last night I worked, I got a great reminder of just why we require two RNs to be present at all births.

The Scenario

The nurse who had the patient in room 2, Barb, was an experienced L&D nurse who had an orientee, Marcy, working with her.  When one of my other coworkers mentioned that Barb and Marcy’s patient was about to deliver, I took a look at the strip and started heading down the hall.  As I was “up”–patient-less and waiting for an assignment–I was ideally free to help in the meantime.

“Well, I dunno, Sophie.  She should be good.  She has Marcy in there with her, and she’s almost off orientation.”  Breanna called from the desk.

“Oh, it’s no problem.” I replied, keeping in mind the happy FHR strip I had just seen on the monitor.  “You never know, after all.”

“True.”  Breanna agreed plainly.

As I arrived in the room with the doctor and the surgical tech, I prepared the bassinet, laying out the blankets, placing a blanket on mom’s chest, and making sure that suction, oxygen and my emergency equipment was functioning and turned on.

Barb and Marcy were helping their patient push, which was taking longer than they had expected for the first-time mom, but baby was clearly at about a +2 station and making progress with each push.  About five minutes later, baby’s head emerged, followed by the rest of his body with one last push.

As the doctor cut the cord, I stepped up at the bedside, drying and stimulating the baby as he was placed on mom’s chest.  APGARs are a little low on this one, I noted as I realized the baby wasn’t crying, had central cyanosis, and he wasn’t moving much.  Moments later, I heard the distinct sound of grunting on the end of each breath and retractions appeared around baby’s sternum.

Seconds into meeting this new little boy, it became obvious that he would require a little extra attention.  I kicked my assessment skills into high gear as I reached for my stethoscope to take a closer look.

Drying, Stimulating and Crying

Drying a baby is important as babies have difficulty maintaining their own temperatures, so the longer baby stays wet, the more likely it is for him to get cold and potentially experience some of the consequences thereof: dropping blood sugar, lethargy, and low blood oxygen to name a few.  While some of the “goop” (AKA: vernix) that baby is born in has been shown to protect baby against infection and help regulate baby’s temperature, making sure baby is dry is of paramount importance immediately after birth.  It is important to note that while some of the vernix will come off with drying, enough will stay on the newborn to provide the benefits associated with delayed bathing (which is a topic for another post!).

A natural result of drying baby is the stimulation that occurs when the blanket makes contact with his skin, and this stimulation usually causes babies to cry.  Crying will naturally help to clear any fluids that baby might have gulped on his way out, therefore opening his lungs and getting him used to the idea of breathing on his own.

Skin Color

Cyanosis is a general term that refers to a bluish coloring of the skin due to a lack of blood flow or poor oxygenation.  A little cyanosis of the hands and feet actually isn’t uncommon in newborns and is called acrocyanosis.  Acrocyanosis occurs normally as baby transitions from being in-utero to having to breathe on his own after birth: slower or decreased blood circulation to the extremities is normal as baby’s body learns to support itself through breathing.

Central cyanosis means that a baby looks purple or blue in his or her trunk.  When the infant’s chest, abdomen or face appear purple, it can be a sign that baby isn’t getting enough oxygen all around.  Though central cyanosis isn’t in and of itself indicative of decreased oxygenation, it is an indication to place an SPO2 monitor on baby’s right hand and make sure that the discoloration you’re seeing isn’t from low O2 levels.

Muscle Tone and Startle

Decreased movement is another potential sign of trouble.  When babies cry, they naturally tense their legs and arms.  In general, crying is a whole-body experience for a newborn.  Also, in addition to the stimulation of having been born, the noise and light associated with birth often triggers baby’s startle reflexes, and if baby doesn’t have good muscle tone and good reflexes pretty quickly after birth, this can point to trouble.

Of note: this can be a sticking point for babies born by C-section.  Vaginal birth and the process of emerging from the birth canal–and all the squeezing that entails–can naturally stimulate a baby as he’s being born and also force fluid out of baby’s lungs.  C-section babies aren’t privy to this particular set of benefits, however, and as a result, sometimes babies born by C-section require a little extra attention to get them to perk up after birth.

Retractions and Grunting

Retractions are a fancy term for when the skin pulls in around baby’s ribs and sternum as he tries to breathe.  The direct result of a baby working extra hard to pull in air, retractions are a sign of respiratory distress in newborns.

The same goes for grunting, which initially sounds like baby is humming a song.  As baby exhales, he closes his glottis (which normally covers the airway when you’re swallowing food or fluids), which causes a distinctive “ah-ah-ah-ah-ah” sound.  In doing so, he causes a change in pressure in his chest that helps improve his oxygenation.  If a baby is resorting to grunting, chances are, he will need some assistance in the breathing department, whether that be suctioning, oxygen administration, chest percussion, or a combination of all three.  Grunting can be a last-ditch effort to open baby’s lungs before things go south, and I’ve seen grunting babies decline from grunting to assisted ventilations (bagging) to intubation (ventilator) depending on the source of their respiratory compromise.

*Of note: breathing is a big deal.  I know that sounds like a given, but in most babies who require resuscitation, breathing is the culprit of their distress.  Say you have a baby who’s born at term with central cyanosis and a no heart rate.  Even before you consider starting chest compressions–even if baby didn’t have a heartbeat at all–per Neonatal Resuscitation Guidelines (NRP), you must give adequate assisted ventilations (bagging) before starting chest compressions.  Most of the time, correcting problems with baby’s breathing will correct everything else.

APGAR Scores

At one minute, five minutes and ten minutes after birth, nurses assess something called an APGAR score.  This quick, objective assessment looks at five categories: skin color, heart rate, breathing effort, muscle tone, and reflex irritability.  At most, baby can get a “2” in each category.  At the least, he can get a “0”.  So on a scale from 0 to 10, an APGAR score tells a provider quickly how a baby is transitioning.

At one minute, my baby scored as follows:
Breathing: 1 -irregular, discoordinated breathing efforts
Heart rate: 2 -pulse is 150bpm, normal range
Muscle tone: 1 -baby has some muscle tone present, but less than normal
Reflex irritability: 2 -baby’s reflexes are normal
Skin color: 0 -baby has central cyanosis

Total APGAR: 6
(As a reference, most babies are born with APGAR scores of 8-9.  A score of less than 7 indicates a need for medical attention).

Back to the Scenario

With baby’s physical assessment looking borderline, I took the baby to the warmer with his mother’s enthusiastic permission.  I placed an SPO2 (blood oxygen) monitor on baby’s right hand and looked for a baseline.  Heart rate was in the 170’s–up from when I had listened to him on mom–and his blood oxygen was lower than normal.

With audible gurgling and coarse lung sounds, suction was in order.  I suctioned baby’s nose and mouth quickly, immediately pulling out some thick, clear secretions.  Suctioning can be an irritating process to a baby which can have the added benefit of making baby cry.  My baby did just that.  He cried immediately after I suctioned him, producing more fluid from his mouth and nose.  A few suctions later, baby’s heart rate came down, his O2 went up, his retractions stopped and grunting significantly decreased, and we were looking at a much happier boy.

In the end, this baby did well.  He was brought back to his mother and monitored for the rest of his time in L&D, but he transferred to postpartum without issues and was discharged normally with his mom a few days after he was born.

However, this scenario just goes to show: a happy strip doesn’t mean a happy baby, and it pays to stay on your toes at all times!


The Mystery That Is The Cervix

L&D nurses are weird.  And with that broad generalization, I’ll happily be the first to lay claim to it.  As if the very existence of this blog isn’t proof that at the very least, I’m a bit touched, I don’t know what would suffice as evidence.

Happily, in my current job as well as in all previous, I’m far from alone.  Unlike in my previous jobs, however, L&D nursing involves a skill that is routinely required and arguably somewhat difficult to master: the art of the cervical exam.

I know I’ve alluded to the complexities of cervical exams in previous posts, but in this one, I’m going to dive into why they’re just so darn difficult at times.  I realized as I took place in an admittedly strange but surprisingly commonplace ritual on my unit the other day that cervical exams are something of a low-key hazing for orienting RNs who have little to no OB experience, and that included myself at one time.  Abby, one of my new coworkers, was on her way to check her patient who we were trying to determine whether or not to admit for labor, and she was a bit apprehensive as she hadn’t had a whole lot of experience checking women whose cervixes were dilated to less than 5cm.

So as she walked past the desk, the four of us who were there to witness her brave march to triage looked up from our charting, waggled our fingers her way, and gave her our best parting wishes.

Mystery Cervix

So, now that you’ve gotten a look into the oddities of my workplace, let me explain from the very beginning.

The cervix is a round, muscular ring of tissue that connects the vaginal canal to the uterus.  It is essentially the gatekeeper to the womb.  In non-pregnant women, the cervix is typically 2-3 cm long.  When women become pregnant, the cervix is what allows the sperm to enter the uterus, travel up the fallopian tubes and fertilize the released egg(s).

In a pregnant woman who is not yet in labor or nearing her due date, the cervix should be closed, thick and high in the vaginal canal.  As the baby grows, the baby’s presenting part (hopefully the head!) will push the cervix down, and by the 3rd trimester (sometimes even by the 2nd), the cervix should be descended into the vaginal canal far enough that it can be felt by a healthcare provider during a vaginal exam.

Because I need visual representations to really understand things, I found you this picture, courtesy of the CDC:


The Basics of a Cervical Exam

When performing a cervical exam (also called a vaginal exam; these terms are used interchangeably, although the cervix is what you’re looking to assess in both instances), the provider uses the index and middle finger of the dominant hand, inserts those fingers into the vagina, and feels for the cervix.

Especially when you’re starting out, making sure your patient is in a good position before you perform the exam is everything.  NOTE: make sure that you make it clear to the patient that you’re going to perform a cervical check and ask her if she wants people to leave the room before you do so!  Some women will kick out everyone except you.  Others have no problem with having their father, uncles, grandfathers, brothers, and about 20 male cousins all watching as you check.  Either way, be sure to ask!

In general, you want your patient to be lying on her back in bed with the head of the bed flat.  Have her bring her heels to her butt and let her knees fall out in a butterfly position.  Use plenty of gel.  No one likes a dry check, and if she’s uncomfortable, she will instinctively scoot back and up the bed, fighting you all the way (this is also known as “climbing the bed” in the vernacular of this particular specialty).

Another trick I’ve learned along the way is to sit on the bed as you perform the exam.  This gives you a stable base from which to perform your check, and if you really need to reach for that cervix, it’ll be a lot harder to do it if you’re standing up.  You can also keep a hand on her leg that’s nearest you, not only reminding her to stay relaxed, but also as a means of protecting yourself should she kick, either intentionally or reflexively (for the record, I’ve never had this happen, but I fully expect it will and there is nothing wrong with being prepared!).

Especially if she’s young/nervous/sensitive, be sure to talk her through it.  Tell her what you’re doing, what she’ll feel and remind her to breathe through any pain she experiences. Be honest with her.  If you can’t feel her cervix low in the vaginal canal and you’re going to have to push posterior (toward her back), tell her it will be painful.  Encourage her to tell you if she has a history of sexual abuse as this can severely impact how you approach a cervical exam.  Don’t be afraid to stop your exam and give her a break if she’s really not tolerating the process well and resume the exam after you’ve both had a chance to take some deep breaths.  Some multips have been through so many cervical exams, they don’t really care anymore, but err on the side of caution.  Cervical exams are by their very nature uncomfortable and extremely intimate.  Be the kind of examiner that you’d want if you had to have your cervix (or your wife/girlfriend’s cervix) checked.

Something to keep in mind (and something that may new L&D nurses struggle with) is that sometimes, no matter how hard you try, cervical exams will hurt your patient.  That can be hard to come to terms with as a nurse as we are accustomed to relieving pain, not causing it.  This particular exam is incredibly intimate and involves extremely sensitive areas of the female anatomy, which can make it difficult for you as a nurse to carry on when you know your patient is in pain as a direct result of your actions.  I promise, you’ll get quicker and more accurate as time goes on, but no matter how good you get, sometimes you won’t be able to avoid causing a bit of pain with cervical checks.  Stick to the guidelines in the paragraph above, however, and most patients will still trust you, even after a tough check.

A final piece of advice for this section: when you know the exam is hurting your patient, you can’t talk her through it/apologize afterward too much.  And usually both are required to keep her trust after an uncomfortable check.

The First Time You Check A Cervix

The cervix can be tough to find, especially for new L&D nurses because as at first, pretty much everything in there just feels warm and mushy.  Most new L&D nurses won’t feel the cervix the first time they perform a vaginal exam.  It often takes a few vaginal exams to not only feel comfortable enough to feel around for something that isn’t just vaginal wall, but also to get an idea of what isn’t cervix so that when you do feel one, you know it’s something different.  Usually, it takes a few awkward moments of feeling around in there and a near-accidental encounter with a cervix to realize, “oh, that‘s a cervix!”.  If you’re new to L&D and struggling with vaginal exams, welcome to the club.  There are times where I still can’t find cervixes (especially closed or only slightly dilated ones!) and need to call for a backup checker (typically, the charge nurse).

Standard Deviation: The Art of Cervical Exams

Please note that cervical exams are something of an art.  No two cervixes are the same–just like all nurses and doctors are different.  So two different people may check the same cervix seconds apart and get different readings.  Why?  Because there is no way to objectively assess cervical dilation.  In all cervical exams, you’re stuck with a subjective manual exam.  Sorry, no magical cervical measuring tape here.  A cervical exam is based on personal interpretation of one’s own assessment.

So when I check a lady and say she’s a 2 and the next nurse checks and says she’s a 1.5, that may only mean the second nurse has bigger fingers than I do.  Really.  It can be that arbitrary.  Or maybe I checked during a contraction and the next nurse checked between contractions (which is generally the polite thing to do, though early on in labor, your patient may not experience much pain with contractions or feel them at all!).  So while cervical exams are certainly an important skill to develop, it is important to keep in mind that they’re not always going to align perfectly from nurse to nurse (or doc to doc or doc to nurse etc.,), though they should at least be in the ballpark of each other.  Usually, I’m within 1cm or less of other nurses’/physician’s assessments if there’s any deviation at all.  That’s a good goal to strive for.

Cervical Consistency

Depending on dilation and labor stage, cervixes can be hard, medium, or soft in consistency.  As cervixes dilate and thin, they also become softer.  A hard or moderate cervix can sometimes feel “crinkly” on the edges.  A cervix of this consistency typically indicates very, very early labor or a woman who isn’t in labor at all.  A soft cervix feels a lot like an earlobe. Usually, you’ll feel a soft cervix in women who are either near their due dates, overdue, or in labor.

What Am I Looking For?

When performing a cervical exam, the nurse is trying to determine if the cervix: 1) has dilated, or opened; 2) has effaced, or thinned out; 3) has a soft vs hard consistency; and 4) is anterior, posterior or centrally located on top of baby’s head.

Mystery Cervix 2 - Copy


In the diagram above, the light purple section represents the dilation of the cervix.  You can see the cervix is somewhat descended into the vaginal vault below, though keep in mind that even in a non-pregnant state, part of the cervix normally protrudes into the vaginal canal.  The inner os and outer os are key in determining dilation.

Mystery Cervix 3

In order to truly determine dilation, you need to be able to reach through the cervix with your finger(s) and touch the baby’s head. The degree of dilation at the inner os is the true dilation of the cervix.  Keep that in mind as that has tricked many a newbie before (including me!).

Tip for determining dilation early in your career: take a paper tape measure (the kind used to measure babies) and tape it with the centimeter side up on the back of your name badge.  After you check a cervix and discard your glove, use your fingers to check what you felt against the tape measure.  This can be a good double-check to see if your assessments are relatively accurate.

Early Stages: Thick, High and Barely Dilated

In a patient who isn’t too far dilated or effaced, a cervix can be not only hard to find, but hard to check.  This may be because it is so long that it’s hard to get through to the inner os, or it could be posterior (around the back of the baby’s head) and a long ways away from your curious fingers.  A closed cervix usually feels like a dimple and can be really, really difficult to even find.

Personally, I call dilation based on the following:
Fingertip: I can get 1 finger through the cervix, but I can’t quite put it flat on baby’s head at the inner os.
1cm: 1 finger through to the inner os, flat on baby’s head.
2cm: 2 fingers on top of each other through to the inner os on baby’s head.
3cm: 2 fingers side by side through to the inner os on baby’s head.
4cm: 2 fingers through to the inner os, slightly preadable between the edges of the cervix to a degree I can show you on my fingers, but can’t really describe. (This is where your tape measure comes in handy!  Figure out what 4cm looks/feels like with your fingers!)
5cm: 2 fingers through to the inner os, spreadable more so than a patient dilated to 4, but less than 6.  Again, hard to describe without showing you.  Make sure to use your tape measure!

*Your method of determining dilation may be different than mine based on your finger size!

Later Stages: Wide and Thin!

 Mystery Cervix 7

As dilation continues, the cervix will begin to feel less and less like a tube and more and more like a rim around the baby’s head.  At a certain point, you will no longer be able to spread your fingers wide enough to determine how dilated your patient is.  When this happens, the best method of checking dilation is to find the cervix and to try to put as much of your fingers on it as possible between the edge of the cervix and wall of the vaginal canal.  Again, your assessment may vary from mine based on finger size, but my general guidelines are as follows:

6cm: At this dilation, I can usually still spread my fingers enough to perform an adequate exam.  However, if I try to put my two fingers on the cervix, there is more cervix than I have finger width.
7cm: I can get 2 fingers side by side on the cervix. *(Remember, 2 fingers side by side is my measurement for 3cm, so if there is this much cervix left, I simply subtract from 10cm to get my dilation.  Same goes for the following dilations!).
8cm: I can get 1.5 fingers size by side on the cervix.
9cm: I can get 1 full finger on the cervix.  Usually, the cervix feels pretty thin by this point.
9.5cm/lip/rim: a little tiny strip of cervix is still present on your exam.  So…close!


Generally speaking, as a woman’s cervix dilates, it is also going to thin out.  So the more dilated a woman is, the thinner her cervix should be.  As a woman’s cervix effaces, it lets down the baby’s head into the vaginal vault, so as this progresses, you may notice baby’s head getting lower and lower and that with each check, you have to go in less and less distance to find the head.  We measure effacement in percentages in increments of 10 from 0 to 100.

Mystery Cervix 4

Starting at the thick end, 0% effaced means a woman’s cervix hasn’t thinned out at all.  Now, typically, when a cervix is this thick, it’s closed.  Unless confirmed by ultrasound, it is fairly unlikely that you will ever be able to insert a finger into a cervix that is 0% effaced, though I’ve felt some that are pretty darn close.

As you might have guessed, 50% effaced is halfway thinned out.  On my own assessment, I say that a woman’s cervix is 50% effaced when it comes up to my first knuckle.

From 50% effaced, each increment of 10 brings you a little bit closer to fully effaced, or 100% effaced.  Eventually, the cervix may feel so thin and may be so firmly pressed down by baby’s head that it is thin as paper, at which point we’d say the patient is 100% effaced.  She just needs to finish dilating and we can think about having a baby!

As you gain experiencing with checking cervixes, you’ll also notice that some cervixes will feel stretchy and you’ll be able to stretch them with your fingers.  A stretchy cervix is a happy cervix.  This usually means your patient is going to dilate nicely.

It is important to note that in general, first-time moms (primiparas) will undergo more effacement first, then dilation.  Mothers who have already had a baby or babies (multiparas) tend to dilate more, then efface.  So if you check a primipara who is in labor and you note her cervix is extremely thin, and then on your second check, you can’t find it, slow down, retrace your steps, and check again.  I’ve had patients who have been fully effaced at a dilation of 3.  Those cervixes are darn near impossible to find, but typically, you can if you’re thorough!

Cervical Position

As I’ve referenced above, cervixes aren’t always straight back.  Sometimes, especially in a mom who isn’t too far dilated and isn’t really ready for labor, her cervix will be posterior, or to the back of the vaginal vault.  Some cervixes are very anterior, or toward the front of baby’s head, and they sit “up”, just past the pubic bone.  Some cervixes are off to the sides.

The truly wonderful ones, however, are in mid-position (straight back), soft, and consistently dilating/effacing in an effort to bring us a baby.

Mystery Cervix 5

Mystery Cervix 6


Although station isn’t related to the position of the cervix, this is also something you’ll be paying attention to when you check your patient.

As you check mom’s dilation and effacement, take note of where the top of baby’s head (again, presenting part, so hopefully the head!) is in relation to the ischial spines (bony prominences of the pelvis that are in the narrowest area of the vaginal vault) .  Even if you have to go way back to find mom’s cervix, the baby’s head may be low in the vaginal vault, and where the front-most part of baby’s head is in relation to the pubic bone determines station.


In terms of station, the baby’s head is said to be fully engaged when he reaches 0 station.  By the time baby is at 3+ station, the head is crowning.  Typically, by the time baby reaches 1+ station, the head may be just visible when mom pushes with contractions.

Tricks for Cervical Exams

A good trick to check a minimally dilated cervix or any woman who you are checking for the first time is to use your middle finger (or longest finger) to sweep along the baby’s head, starting anteriorly (toward the front) and going back.  Don’t forget to check the sides!

For minimally dilated cervixes that are too far back to reach: when you find the edge of the cervix, hook it with your middle finger and pull it gently down toward you.  Usually, you can insert your second finger at this time and get a good feel for dilation and effacement.

Another tip is to have your patient make a fist and put it underneath the small of her back.  This can help to tip the cervix forward in the vaginal vault so it’s easier to reach.

If baby’s head is not engaged in the pelvis, sometimes pushing down gently on mom’s belly can bring a floating baby down, therefore pushing the cervix toward you.

Most of all, be patient and don’t be afraid to have someone check after you, just to make sure!

Happy cervical exams, fellow L&D nurses!  May the cervix be with you!
