I just wanted to share my tremendous enthusiasm for the Neonatal Resuscitation course I took today with Karen Strange, the traveling NRP instructor for homebirth midwives.
I've been taking NRP classes for about 12 years now, and although I'd heard really fabulous things about Karen's classes, I found myself wondering what could really be that different from the standard course.
Well, I was extremely impressed on three counts:
1) Karen's teaching techniques are excellent; she makes it easy and non-threatening for experienced midwives and students alike to understand NRP.
2) The recommendations for adapting NRP guidelines to homebirth are evidence based and very sensible.
3) Karen includes a great deal of information and insight about how considering things from the baby's perspective will help your resuscitation efforts to be more effective and be less likely to cause long-term negative effects for the baby.
And, after 12 years of various continuing education courses, I was VERY grateful that this course was engaging and paced well. PLUS . . . Karen brings CHOCOLATE!

of asphyxiated newborn infants with room air or oxygen: an international
controlled trial: the Resair 2 study.
100%
OXYGEN IN NEONATAL RESUSCITATION: IS IT STILL APPROPRIATE? from
THE
NEONATAL RESUSCITATION PROGRAM at Children's Hospital Foundation of
Winnipeg in Manitoba.
There was no difference in mortality or moderate to severe hypoxic-ischemic
encephalopathy, but there were fewer infants with low 1- and 5-minute Apgar
scores, and the time to first breath was shorter in the room air group.
The authors postulated that 100% oxygen might delay the onset of spontaneous
respirations.
Ya know, folks forget just how controversial resuscing newborns with
O2 was when it was first proposed. There were a number of studies showing
that room air was superior -- it was noted that resuscing with O2 actually
inhibited the breathing reflex. In fact for many decades resuscing was
done with a mixture (this'll shock ya') of oxygen and carbon-dioxide in
order to counteract the side effects of oxygen.
The controversy over O2 vs. O2-CO2 ran for years --- O2 finally winning
out when compared to the mixture. But by that time many resusc units could
only be used with pressurized mixtures --- and the use or room air fell
into neglect in many regions of the country.
As someone said "My ambubag can't work with room air".....
Anyway, I don't want to give the impression that I do not approve of
oxygen! Certainly I do. It's good stuff. I just think it's role in
resuscitation should be understood as "secondary" to ventilation (by whatever
means). And that I think it's not a great handicap if the law forbids a
midwife to carry it.
This is of course very interesting info and worthy of further research.
Let's not forget though, that the use of O2 for adults (ie the mother)
in cases of hemorrhage/shock is NOT being disputed, so it is still helpful
to carry supplemental O2 if you can get it and are willing to carry it
depending on state laws/personal convictions. The recommendations
for 100% O2 for neonates still stands according to the latest NRP manual.
Perhaps by the next revision we will see the recommendations change.
Or perhaps further study will determine that it is indeed a better thing
to use 100 % O2 for neonates also. We'll have to wait and see.
[From an NRP instructor, 10/04]
The guidelines have still not changed for the American Academy of Pediatrics
at this time which states that that if you have oxygen available you should
use it. The new NRP book will be out in 2006 and they will be addressing
the issue of 100% versus room air. Here is a sample of what they
are stating in their instructor updates:
A representative of AAP/AHA/NRP " recommended that O2 be administered
by PPV using a face mask or ET tube if respiratory efforts are absent or
inadequate. Blended O2 from 21-100% should be available in the delivery
room and O2 should be administered and guided by pulse oximetry if possible.
Lastly, judicious use of O2 is reco'd in premature infants.
If O2 is not available resuscitation should be initiated with room air."
They also quotes some studies outside the US that reco beginning resuscitation
with room air first.
These guideline are going to take a while to get with the program and
reflect what all the studies are showing. Nonetheless, the guideline are
still what is being done in the hospitals.
As far as oxygen tanks go, regular oxygen is not heated or humidified.
That is done with other machines in the hospital for long term use not
short term. The only difference I know of between welding grade and
medical grade is that they both come out of the tank exactly the same,
medical grade is checked for purity a second time. As far as aviation
O2 is it the O2 in the plane in cylinders or what come down from the ceiling
if plane does not maintain pressure? That is 21% or room air.
From Henci Goer, Dec., 2007
My co-author, Amy Romano, has finished the chapter on newborn procedures
that will be part of the new edition of Ob Myths. Routine suctioning is
worse than useless; it's harmful. Evidence suggests that suctioned babies
take longer to achieve normal oxygenation levels. Linda Smith has written
about the adverse effects of suctioning on initiating breastfeeding. Suctioning
c-sectioned babies isn't even logical. The problem is fluid in their lungs.
Suctioning the nasopharynx isn't going to do a thing about that. Finally,
it is now believed that meconium aspiration results largely from events
occurring in pregnancy. Thanks to randomized controlled trials of suctioning
for meconium, the sole remaining accepted indication is meconium staining
and a nonvigorous baby--and that is probably because no one has yet performed
an RCT on this issue.
<<Among them, some will develop a meconium aspiration pneumonia
and will go on mechanic ventilators. Very few of them will have residual
health problems. The practice of suctioning the mouth and throat of the
baby just before the delivery of the shoulders is now considered useless.
The routine intubation and suction of the trachea just after birth in the
case of meconium staining is also considered useless according to recent
studies. It does not improve the outcome.>>
Evidence-based practices for
the fetal to newborn transition - Many common care practices during
labor, birth, and the immediate postpartum period impact the fetal to neonatal
transition, including medication used during labor, suctioning protocols,
strategies to prevent heat loss, umbilical cord clamping, and use of 100%
oxygen for resuscitation. Many of the care practices used to assess
and manage a newborn immediately after birth have not proven efficacious.
Gastric
suction at birth associated with long-term risk for functional intestinal
disorders in later life.
"Noxious stimulation caused by gastric suction at birth may promote
the development of long-term visceral hypersensitivity and cognitive hypervigilance,
leading to an increased prevalence of functional intestinal disorders in
later life."

Guidelines for Neonatal Resuscitation: An Excerpt From the Guidelines 2000
- Of particular note is the change in guidelines for meconium - " Meconium-stained
amniotic fluid: If the newly born infant has absent or depressed respirations,
heart rate <100 beats per minute (bpm), or poor muscle tone, direct
tracheal suctioning should be performed to remove meconium from the airway.
" and "There is evidence that tracheal suctioning of the vigorous
infant with meconium-stained fluid does not improve outcome and may cause
complications"
The issue of when to suction for meconium has undergone major revision
- thankfully for the babies, they should be getting suctioned a lot less
than they used to be! See About Meconium.
I've been carrying that same bulb syringe and DeLee for ages[Grin]!
I just wipe the baby off. And if you put her/him head down you can SEE
the junk run out of his/her nose and mouth -- the natural mechanism is
for the baby to drain and "spit" and THEN breathe, so i want to encourage
it to happen that way.... (I "suspect" that suctioning -with a bulb- might
make a baby try to breathe before it's cleared)....
How do I know whether to suction? The sign I use is real simple -- I
gently touch the baby when just the head is out. If he purses his lips
and looks like he's "trying to spit: then I figure all the reflexes are
there and I'm not going to need to suction....
I used to suction on the perineum. I used to suction automatically.
I finally figured out that suctioning and stimulation are great first steps
in a baby who is a slow starter, but that a baby who clearly getting it
together on his or her own doesn't need me to suction.... the baby seems
to be quite capable of dealing with secretions on its own, and thus the
suctioning is being done to make me feel better rather than because it
is necessary. Now I wait, unless meconium is present. Then I suction on
the perineum and afterwards, of course. But this in not the normal scenario.
Still, it has been a hard habit to break......
The thing of it is, is that suctioning isn't always such a benign intervention.
There is clear evidence that over vigorous suctioning can cause babies
to brady down which is not something we want. The other thing is that in
my work as a lactation consultant, I have seen a few babies who seemed
to develop oral aversions after really vigourous, deep suctioning, and
this interfered greatly with the establishment of effective breastfeeding.
Count me as one of the reformed "blow-while-I-suction" midwives. I don't
routinely suction anymore even after the birth. I believe it also helps
there to be fewer "sticky shoulder" births.
A crying baby (or even not crying, but pink and good nurser) will clear
their own lungs in my experience. My former partner has a big time problem
with rattly sounds in newborns and always suctions with a vengeance. When
she quit, I got to do things my way and rarely found the need to suction
anymore. At my own niece's birth this past year I intended her to have
as gentle a birth as possible so instructed that there be no suctioning
by my assistants (including my former partner). The kid didn't cry at all
(gentle birth accomplished!) but she did breathe well and needed no help.
She did sound kind of rattly and "mucousy" though for the first half hour.
My partner was as nervous as could be and kept on me about it to suction
her. When she was about an hour old (after everyone had held her and she
got the opportunity to be at the breast a few minutes), I finally relented
and listened carefully to her lungs. I heard nothing and asked my partner
what she was so worried about. She said "You can't hear it?!" I said "No,
show me where she sounds mucousy" So she listened but it was gone. She
couldn't believe it because she had just listened to her lungs about 10
minutes prior and had found it "unacceptable". :)
I do still suction on the perineum for mec though. I can't break that
habit yet, but am not convinced it is necessary.
By allowing natural drainage/clearing, the mom can pay more attention
to the clues to push the shoulders.
Just speculation at this stage, but she's liking what she thinks she's
seeing!
When I spent a week with the NNR team at LA County (a very good team),
I was taught that once the baby is out and needs resuscitation, the bulb
is safer to use than the deLee since deep suctioning can cause a vagal
response and really put an otherwise good baby into distress if used before
5 minutes. But this is after the baby is out, not on the perineum. We were
taught to deLee on the perineum if there is mec (2+ or more), otherwise
I don't suction at all before the birth.
vagal response is pretty common; I think we must assume we should avoid
triggering it if possible.
SO.... What magic thing happens after the baby is out? If suction can
trigger vagal response once the baby is out, why should we think it doesn't
when the baby is still in?
If one wanted to, one could see vagal response on most babies by watching
it appear on the fetal monitor (if it's still reading) when you suction
on the perineum.
The theory behind suctioning on the perineum is that the babies mouth.
throat, nose are filled with gunk and the baby will breath this into his
lungs. If suctioning on the perineum worked to avoid meconium aspiration,
then I don't think we would have ever seen a case of MAS during the decade
or so of obsessive suctioning on the perineum. Wouldn't MAS have almost
disappeared with the introduction of the technique? It did not. The incidence
hasn't changed at all has it? So... why are we still doing it?
That said, I would still wipe, suction and drain a heavy mec baby --
starting on the perineum -- as the first step in anticipated resuscitation.
I think it has an appropriate use there. [Editor's NOTE - the NRP 2000
recommendations would recommend NOT suctioning a vigorous baby just for
me.]
Just thought I'd mention that in the hospital where I am currently doing
my MW training (in Scotland), we don't suction any babies routinely...even
those with mec unless the baby needs to be resuscitated. I have yet to
see any negative results from this practice.
A client was told by a lactation consultant that bulbing the baby at
birth could cause the baby to have "oral aversion" and might interfere
with latching or sucking. I rarely suction a baby, unless the baby
is particularly gurgly, but I was wondering if anyone knows of studies
that support what the client was told about oral aversion?
No... Haven't heard about oral aversion specifically but... I feel routine
suctioning is so invasive! When a baby is trying to catch it's
first air breathing breath we suction and suppress or interfere AGAIN!
Argh! What a bunch of nonsensical loonies we be! We need to
ask ourselves WHY we do such things!!!
I don't like to suction babies, and usually just make rather a show
of it (for the nursery nurse), but rarely do any 'real' suctioning with
it.
I'm just guessing that this is more of a "soft knowledge" thing - probably
mostly anecdotal. I seldom suction, either, and virtually never have
problems getting babies to the breast, but I've also observed that babies
who get lots of mouth suction, in particular, seem to have a tougher time
(these are usually deliveries I'm observing docs doing). Perhaps
its a multi-factoral thing - maybe it has to do with maternal analgesia
which leads to less vigorous babies which leads to more suctioning, perhaps
both of which lead to lousier nursing. Don't know. But I, too,
have heard about "oral aversion" and believe there might be something to
it.
Well, if there are studies, I wonder where they are. If this were
true, we would have a couple of generations of "oral aversion" babies out
there. Bulb suctioning is common in the hospital setting and often
done excessively, IMHO.
We also have lousy breastfeeding stats as a nation, and perhaps some
of that results from moms whose babies just "won't nurse." Many moms
say that they "could not nurse" or "didn't make enough milk," but let us
consider the root of some of those statements. An oral-aversive baby
is exceptionally frustrating, and many mothers will bottle-feed instead.

Neonatal
Resuscitation - An outline review
Neonatal
Resuscitation: the NRP guidelines - another review, possibly outdated,
i.e. from 1995
Consolidating everything I've learned about a resus setup:
We often use those "gel packs" in addition to or instead of the heating
pad. Handy for places where there's no electricity. You can either zap
them in the microwave or put them in a pot of boiling water to heat. Once
they're hot they hold it approx 30 minutes, depends on the particular gel
pack. Find them in the sports section of stores or else at home health
supply places. They go where the heatingpad would go.
Here is what I have experienced in regards to resuscitation. I try to
have a bread board or cookie sheet with a space blanket, regular blanket
or 2, towel padding underneath along with a heating pad. Also a baby hat.
This provides a surface to work on in rare occasions it is needed (which
is preferred to a wet amniotic fluid filled floor with chux pads. Most
of the time the giving of oxygen can happen in mom's arms or just a rub/heel
flick helps the little beings come into their bodies. Always it is good
to encourage the mom and dad to talk to the baby and welcome and encourage
breathing. The beauty of homebirth is that resuscitation measures happen
quicker instead of the cord being cut and the baby handed off to the pediatric
team. Therefore less is required to get a reluctant baby started. The last
baby I helped get started came out all floppy and white with good heart
tones though. I gave a few breaths mouth to mouth as the assistant got
the O2 tank, and then gave some puffs. It worked and he went from a 5,
and then to a 9 Apgar by five minutes of age.
One must be careful to not pump the bulb of the bag too hard as a hole
could be blown in the lung of the baby. The seal should also not be too
tight. Also, don't have the oxygen up over 5 liters per minute as this
could create blindness for the baby. The guy at the welding shop where
I fill my tanks said that I should bring it in partially full but never
completely empty as this could mean contamination of the tank.
Another thing I like to do is to have the assistant at all births put
a cloth over the babies face when just the head is out. The reason I think
this is such a fine idea is that so often a gush of fluid-whether it be
clear or stained or blood follows the body. Holding the cloth there helps
prevent this intake into the lungs of whatever substance it is as the first
breath is taken. Blood is horrible for the lungs of a baby, as it is sticky.
Wiping the mouth, then suctioning only if necessary is the sequence. If
meconium is there, I would hope to suction it sooner. Maybe I am superstitious
on this cloth idea, but I do it and believe in it.
I think that there are pros and cons to mouth to mouth and an ambu bag.
There is a transmission of life force with mouth to mouth which I like.
Also a risk of disease spreading. With an ambu bag, the higher concentration
of oxygen seems possibly more effective than air from my mouth. You can
observe the baby better too. From my training, I have learned (in theory)
that if you start early in helping a baby WHO NEEDS IT to breathe, less
is required and outcome is likely to be better. A nice aspect of a homebirth
is that it can be done in a calm manner without panic, in a directed way.
The parents can help by talking to the baby or rubbing him to get a breath.
The cord need not be cut if oxygen is coming through still and it is not
excessively short. For the babies with transient tachypnea or grunting/
flaring/ or retractions, a little oxygen by mask may help. A Russian method
for slowing down tachypnea that my colleague taught me is this: Take the
bundled baby in your arms next to your body horizontally and rock swiftly
left to right, arms in a bit of a figure 8. It has worked.
Other important aspects to helping a baby breathe are:
I am curious about stories of babies that were not here and came into
there bodies when an ambivalent parent welcomed them or they were told
they were accepted despite their gender being the non-preferred one.
For those babies that are a bit slower than normal to get going following
birth, stimulating the acupressure points either side of the spinal column
is spectacularly successful.
Are these specific or do we hit points by just running our fingers down
the sides of the spinal column? --- I ask because "rubbing the back" is
a traditional thing and one of the first things we do - -sometimes just
through a blanket. I assumed it worked by skin stimulation, but maybe it
was some other process all along. It "does" seem to work though [Grin]...
What you are trying to do is stimulate the spot for the vagal nerve--right
below the head. Run two fingers up and down the neck and you will see the
baby respond really well. Turn him over your knee to do it, that makes
it easier to do. Birth is the first subluxation and sometimes the neck
needs an adjusting.
I certainly am not keen on hitting or flicking babies anywhere. I saw
an old GP once throw a bowl of cold water on a sluggish to respond newborn
Well, when I say 'flicking the feet", I don't mean "hitting", just jiggling
and twiddling with them, maybe running my fingers over the heal -- a little
girl once called it "playing with the baby's feet"; a good description.....
The cold water? yeah, I've seen that too. Though it was just cold water
flicked from the fingers -- not too traumatic. Still had to question whether
the baby needed "that" much stimulation.....
Does anyone outside of Oregon "blow" on a baby to stimulate a breath?
Very common here... and often works! Just a quick puff-breath near the
head or chest will often trigger a gasp and then a cry....
From Doctor DeLee in "Obstetrics For Nurses" (1940 edition) pg 510 Treatment
of Asphyxia Neonatorum:
pg 513
Also in Practical Obstetrics (Bland, Montgomery 1932) Under treatment
for asphyxia "warm baths, gentle massage" -- though he also refers to "immersing
it (the child) alternately in hot and cold water."
I REALLY Like what I've seen when we've tried the warm bath -- sometimes
a night and day response. I agree with DeLee's opinion that alternating
hot and cold is too shocking and defeats the purpose.....
[Ed: I can't imagine any mechanism whereby lobelia rubbed on the chest
and back would help, but lobelia is sometimes use for asthma as an anti-spasmodic.
Maybe there's something that needs to relax in the baby's chest in order
to absorb the lung fluid???]
Lobelia, as a tincture is rubbed on the babe's back and chest.
The babe is positioned on a side lying position for 15 minutes
and then positioned on the other side for 15 minutes. By that
time (and I am not kidding) the flaring, retractions, wet lungs are
GONE.
So, in my opinion, giving the babe 30 minutes to see if the Lobelia
will prevent a hospital admission in those borderline situations,
is not excessive.
I've heard some people recommend some positive-pressure ventilation
as a treatment for TTN. They suggest five slow inflations, about
3 seconds each.
The
effect of body position on the respiratory rate of infants with tachypnea.
"The lowest mean respiratory rate occurred when patients were in the
prone elevated position"
We had a baby who was fine at birth, but then at the 18-hour checkup,
his resps were over 100; everything else was perfectly fine. This
baby had had a nuchal forearm, and I wondered whether there might have
been some mild inflammation from this, which caused some neurological TTN.
Then, in thinking about it some more, I realized that the 2 other babies
I'd seen with TTN had also had shoulder issues. Could it be possible
that this is something that would be corrected with a chiropractic adjustment?
Years ago I had 2 primips, 2 days apart with long hard labors.
The first I sent to the hospital and after a few hours they finally c-sec'd.
The other I did at home. Both babes, after 16 hrs developed TTN.
babe in hospital, as I found out later, wound up with some major problems
in NICU for over a week. The second I sent out our local Amish adjuster
as she had just read a circle letter from another amish midwife that had
run her thumbs up the spine of a baby she had had with similar respiratory
problem (hope that is not too confusing of a sentence). Anyway, she
went out and adjusted babe and ran her thumbs up the babes spine.
Babe still had problems and 2 hrs later the dad called me out. by
the time I got there all was resolved.
So my answer is yes. In fact, during the newborn exam I run my
thumbs up the the babes spine after any hard delivery.
In thinking it over . . . yes, both times I've seen TTN have been big
boys with delayed shoulders, so maybe they were torquing in the pelvis
in a way that caused some irritation of the spinal nerbes controlling respiratory
rate.
Good-sized babies often have a tight squeeze for the shoulders and body
to be born. Sometimes the bones in the upper spine get a little out
of whack, and that can cause "transient tachypnea of the newborn", i.e.
fast breathing without any kind of true respiratory distress. And
it makes sense that it could also cause swallowing issues. I would
recommend getting a referral from your midwife to someone who adjusts newborn
spines or does craniosacral adjustments.
Or you could use some national referral lists:
http:
One of my clients with a similar situation was a homeopathy, and she
used lots of homeopathic arnica, and that seemed to help. If he were
older and could understand, you could use some ice to reduce inflammation,
but I don't think I would recommend that for a baby! Or you could
do gentle massage along his spine in the upper back of gently stretch out
his spine by laying him flat and lifting his lower body by the knees or
hips (very gently, of course) and even hanging him upside down by his hips
if he's OK with that.
If you're open to a professional adjustment, that would be my first
recommendation.
Transient tachypnea means rapid breathing in the baby which lasts for
a while and goes away... as opposed to "tachypnea" which does have some
sort of cause and remains untill the cause is fixed.
It is true you can't exactly diagnose TTN untill it DOES go away, but
you get to that conclusion by looking at the symptoms and going through
a "process of exclusion".
it ain't hypothermia because the kids color is normal and he is toasty
warm.
We really should call it "tachypnia of unknown origen" untill it resolves.
My questions here are.... would percussion have taken care of this fluid
that was not audible? Could that have been the cause of the grunting and
tachypnea? Anyone been here before? How long is too long to sit on something
like this?
We have used percussion and steam for these big babies with good results.
We turn on the hot water in the shower and let the bathroom get good and
steamy and take the baby in and percuss with the mask from the ambu bag.
So far it has worked well.
I really hate to take these big healthy ones in just for TTN. I will
transport a smaller baby faster though. Maybe thinking the smaller baby
will have less reserves? I have seen this more often with the bigger 9-10
pounders and it tends to set off warning alarms in me if a 6-7 pounder
is breathing fast.
what percentage of babies do you have with "transient respiratory distress"
and the like in absence of infection or other problem? How do you
handle it?
I think about one percent would be really close.
I think we see it mostly in babies who are born extremely rapidly --
the kids who go from floating to to birth in a contraction or two. I've
got a theory these are kids who just didn't get enough chance to drain
out well and whose lungs are a bit wet.
It usually never gets bad enough to need anything more than observation
- I think gentle handling and frequent nursing is all the treatment most
babies need. we keep an eye on them; do nothing else unless they
are deteriorating, or having more than very mild, occasional retractions.
I tried immersing one baby in a warm bath once and was surprised at
a very quick improvement. Don't know if it would be repeated -- haven't
had the chance to try it again yet.
To determine if it is heart or true HMD (Hyaline Membrane Disease),
I see if they will suck my finger. If they are weak with a heart
defect or true HMD (also diaphragmatic whatever), they cannot suck.
Another fairly good rule of thumb: if the baby pinks up when he cries
then the problems is gunk in the lungs or something which is preventing
full breathing (treatment is time or better drainage/suction).
If he gets duskier or paler when he cries, then he/she has good air
movement but the problem is in the blood circulation (this means probably
a defect which needs treated)
<Okay, I have heard of this 'wet lung' for some time and I always
assumed that babe took in a little fluid, nothing major on a term babe.
Is is something different?
The lungs are normally filled with fluid in the womb. The fluid clears
during the laboring process -- both by pressure and hormone response. With
those first few breaths the lungs expand and the little air sacs displace
fluid. SOme of it is absorbed. Some of it drains. But some kids just don't
displace well. They need a little bit more time or pressure. These are
the kids who sound gunky or retract a bit but are pretty good color ---
they seem to clear up somewhere in the first half hour or so. Some of them
develop TTN a few hours later -- and it clears up too.
There are two schools of thought on this issue. One says the baby will
recover faster if he is made to expand his lungs more quickly -- so the
old treatment is to get the baby to cry really well (this is the idea behind
spanking or the old watershock methods). There is a much newer hospital
based idea which advises doing PPV (some say with and some say without
O2) for a few minutes. The lungs are forcibly expanded for a short time
and then the assisted ventilation is stopped.
The other school of thought says that the baby will clear on his own
with a bit of stimulation or time and gentle handling will get him through
-- as long as his color stays good -- and that it will resolve about the
same length of time.
There is another idea out there that giving him mask or blow by O2 will
actually prolong the problem. If the baby is a little low on oxygen he
breaths more deeply and rapidly -- and this is the trick he needs to fully
expand his lungs. If we give him O2 to "make it easier to breathe", then
he has plenty of oxygen -- maybe even more than he needs -- and he breathes
more lightly, gently, slowly and doesn't expand his lungs or clear the
fluid as quickly.
No matter the treatment he will eventually get over the hump -- just
about the time we're thinking of taking him in for evaluation!
Those first 15 or 20 minutes can be pretty unstable -- sometimes we
just don't know which way a baby is going to go.
oh PS -- I forgot another old time trick. Putting the baby into
a bath of warm water is supposed to help pull fluid out of the lungs by
stimulating the circulation to pull the blood into the limbs. I don't
know if the theory holds water or not, but I have seen it work.
We frequently have excellent experience with a homeopathic called Antimonium
tartaricum, used when baby has moist lung sounds and tachypnea and in the
absence of other more obvious, serious problems such as infection, etc.
We usually use 30x potency, crush 2 tablets or pellets between two teaspoons
with a tiny bit of water.
It hasn't worked every time, but I would estimate the success
rate over the last five years that I've used it for this fairly common
problem as >90%. Prior to initiating its use, we found it necessary to
use O2 and extended stimulation, percussion, postural drainage, etc. more
often. Basically our approach is (1) auscultate the lungs and heart sounds
right after birth and listen frequently thereafter. Encourage breastfeeding
after birth as soon as mother and baby are stable and interested (usually
5 to 15 minutes at most). Auscultate lung and heart sounds unobtrusively,
observe infant feeding behavior. If baby is nursing well, continue to observe
lung and heart sounds. If baby is disinterested in breast or lung sounds
are not clearing quickly or tachypnea is present, give Ant. tart. as above.
Re-auscultate lung and heart sounds. Administer another dose of Ant. tart.
if lung sounds not clearing within about 15 minutes or so. I have not had
to use more than 2 doses to achieve clear lung sounds. Ant. tart. even
favorably impressed the anesthesiologist/dad at our most recent birth in
which we had this complication. It was really quite nice to have him there
to confirm what we were hearing, although I was a bit intimidated at first!
[grin] Of course, we are assessing for other more serious problems as well.
Ant. tart. is "widely used in the treatment of . . . respiratory ailments
in babies and young children [and is] reputed to be excellent for respiratory
distress associated with fluid accumulation and rattling in the lungs .
. . " (Homeopathic Medicines for Pregnancy and Childbirth, Richard Moskowitz,
MD, 1992, North Atlantic Books and Homeopathic Educational Services.) It's
certainly made our lives as midwives easier these last 5 years! [grin]
I was at a birth where the baby's lungs sounded wetter than we'd liked,
so I tried, for the first time, the homeopathic Antimonium Tart.
Within two minutes, the kid stopped crying and started rooting - nursed
well. After that, he was only quiet alert - didn't even cry during
his newborn exam. His lungs didn't sound much better, but something
seemed to really help him out. He weighed 9#1oz, by the way.
A meta-analysis suggests that 100% oxygen should be reserved for backup.
Saugstad OD, Rootwelt T, Aalen O
Pediatrics 1998 Jul;102(1):e1
For a self-inflating bag, if you attach the O2 without the O2reservoir
the baby gets 40%. If you remove both the O2 and the O2 reservoir
the baby gets room air which is 20.9%. If you have both the O2 reservoir
and the 100% O2 attached then the baby is getting 90-100% (depending on
the type of reservoir the bag comes with) oxygen.
Suctioning
Anand KJ, Runeson B, Jacobson B.
J Pediatr. 2004 Apr;144(4):449-54.
Suctioning Not Always Benign
I do clinic births and home births and hospital births. I don't really
do anything different in terms of my management based on place (other than
having to work somewhat harder at the hospital to keep things low key).
Suctioning May Cause Sticky Shoulders
A midwife friend and I were talking, and we both observed that we see slow
shoulders a lot less since abandoning routine suctioning. We think that
the suctioning changes the pattern a bit; you get into a pattern of sort
of "hold-everything-while-l-suction-the-baby-now-push.
Neonatal Resuscitation
Voila!You've got your prewarmed blankets and resus board all ready
whenever and wherever you need them.
Helping Baby Clear the Lungs
Ideally, a baby will nurse to help clear the lungs. However, a baby
who's having trouble breathing may not nurse well; an alternative is to
have the baby suck on a gloved finger.
Hot Water Bath for Resuscitation
This consists of removal of foreign matter form the air passage,
preservation of the body heat, artificial respiration, and the treatment
of shock." (He describes suction technique ...)"The infant is then placed
in a hot bath (106degrees). Some physicians place the infant alternately
in hot and cold water -- as severe shock to the little one, and a procedure
the author has never found necessary. In mild cases these measures suffice
to bring about normal breathing.
He goes on to describe asphyxia pallida, which we now call severe asphyxia
or secondary apnea and agrees with the current view that suctioning and
"substitute breathing" --positive pressure oxygen -- needs to be done immediately.
Throughout all these procedures continual care is to be taken
not to fool the babe too much. The skin is wet, the child shocked, and
he refrigerates rapidly. In fact, sometimes the child dies because of too
violent and prolonged manipulations intended for resuscitation. The hot
bath, warm flannel receivers (blankets) and the warm-water bag, gentle
friction with a warmed hand under cover, all tend to keep up the baby's
temperature.
These days we use radiant warmers or HEATING PADS (midwife trick) or moms
own abdomen instead of "warm water bags (hot water bottles).
Wet Lungs
Transient Tachypnea of the Newborn - TTN
Sconyers SM, Ogden BE, Goldberg HS
J Perinatol 1987 Spring;7(2):118-21
It ain't heart defect, because the heart sounds fine and there is good
color and good perfusion.
It ain't infection, because the temp is normal and the baby is alert,
eating, sleeping etc.
It ain't hypoglycemia because the kid is alert, nursing and not jittery.
it ain't aspiration because the breath sounds are quite clear
it ain;'t bloodloss because there was no bleeding and the color is
good etc etc.
Ya go on down the list of possibilities untill you find no reason for
the rapid breathing... and you get a "presumptive" diagnosis of TTN.
And then when it goes away you get a "confirmed diagnosis" of TTN.
