Can Chiropractor Adjustments Cure Problems With Breastfeeding?

Can Chiropractor Adjustments Cure Problems With Breastfeeding?

I have to admit I know very little about this field despite having friends are practitioners. A few months back, a family in the NICU sought to address the care of their premature infant who was not progressing as fast as they wanted by involving an alternative healer. The healer who would come in the night without leaving notes about what they had done and it left us all wondering what benefits the healer was providing. The family mind you was delighted with the care they were receiving and as we saw no adverse effects following treatments and the family had consented to him coming we allowed this practice to continue.

As I reflected on this experience I turned to the literature to look at the third most common health practitioner in North America after doctors and dentists; the Chiropractor. The truth is I have known for some time that Chiropractors provide treatments for newborns and children but have been somewhat oblivious as to what services they can offer. My curiosity was piqued by finding that Chiropractors have been treating newborns for difficulties with breast-feeding. Before I turn to the evidence for such practice it is worthwhile reviewing what Chiropractic is based on.

Chiropractic is actually a relatively new field having been developed by D.D. Palmer in 1895, who was a magnetic healer. He believed that many diseases were caused by joint subluxations of the vertebrae, which would lead to interruptions of neurological impulses thus creating disease. Having said that the indications for Chiropractic have expanded over time as the profession has developed. While initially practiced in adults the use of such manipulations has expanded over time to include children some as young as newborns.  One such goal is to improve success with breastfeeding and a sample manipulation is shown in this video:

When it comes to breast-feeding the number of studies examining efficacy are few and far between but the largest study is worth studying as at the very least it outlines what it is that the Chiropractors believe they are treating. In 2009 JE Miller et al published the following article: Contribution of Chiropractic Therapy To Resolving Suboptimal Breastfeeding: A Case Series of 114 Infants. In this case series, maternal infant dyads who were on average 3 weeks of age at presentation (but the most common age of presentation was 1 week) were referred to a Chiropractor for help in establishing exclusive breastfeeding. The infants in this study most commonly presented with issues latching on rather than drawing milk once latched. In fact the issue more often than not was simply not having the infant show interest in latching. The findings of the Chiropractors assessing these infants as to the etiology of the problem were as follows:

  • Altered tongue action resulting in ineffective latch
  • Decreased mandible excursion preventing wide mouth opening
  • Hypotonic suprahyoid muscle group preventing sufficient mouth opening
  • Displaced hyoid preventing balanced tongue activity
  • Aberrent cervical range of motion and/or posterior joint restrictions affecting infant posture and position
  • Hypo or hypertonic orbicularis oris, masseter, digastric muscles causing imbalance in muscle torque
  • Temporormandibular joint laxity or imbalance
  • Mechanical changes in neural function relative to cranial or cervical distortion

The number of treatments were from 1 to 9 with a mean of 4. These manipulations typically involve the hyoid bone, TMJ or cervical spine. Exclusive breastfeeding was reached in 78% based on a 10 point numerical scale and discussion with families.

Interestingly the frequency of birth trauma was notably higher in these patients than in the general population, which is used as an argument to suggest that these infants were at risk of injury in need of manipulation.

I have to give credit to the authors of this paper as they presented this information but acknowledged that the improvement in breast-feeding rates could be a function of allowing time for the skill to develop as opposed to the effect of their treatment. The only other study I located was a similar case series from 2012 looking at 19 patients showing similar improvements. The problem though in all of this is the lack of blinding of the interventions. Families that seek out a Chiropractor as they have already seen a lactation consultant, midwife and physician are clearly dedicated to the plan of breastfeeding and are motivated to take that extra step to achieve it. Whether the manipulations provided were effective or it was simply the result of dedication and time one will never know but I suspect that may be the case.

An additional factor that is worth mentioning is that with a higher rate than in the general population of birth trauma it is plausible that the delay in initiation of breastfeeding is related to after effects of birth as opposed to any true subluxation whether true or not.

Lastly one significant concern with respect to manipulations of the head and neck despite being well intended is the risk although small of vertebral artery dissection and stroke. This has been reported in adults and only once in Pediatrics but all families need to ask whether the proposed benefit is worth the small risk of a significant neurologic injury. My bias as you can probably guess is that implementing unproven therapy that carries a small but devastating risk is not worth it.

There is no doubt that the literature will become scattered with such case reports showing the benefits of Chiropractic care in achieving breast-feeding but my suggestion is to give it time. If it is meant to happen it will and exposing your infant to manipulation of the hyoid bone or neck is too fraught with danger to be worth pursuing.

Reducing length of stay for preterm infants.  Ask them, don't tell them when to feed!

Reducing length of stay for preterm infants. Ask them, don't tell them when to feed!

Will that be q2h, q3h or q4h feeding?  When I started my residency in Pediatrics that was the question I needed to ask before writing an order to start oral feeding in a preterm infant.  At the time it seemed perfectly reasonable but I have to admit the question for me was “What if they aren’t ready?”.  Does a baby who won’t take the breast or bottle at the 3 hour mark clearly show they aren’t able to feed or that they really are just not ready to feed?  We commonly say that children are not small adults.  Hospitalized adults commonly will utter the words “I’m not hungry” when their food tray is brought to them.  This may be a reflection of what has been put before them rather than whether hunger exists or not but they seem to be able to be ready to eat so why not children and by extension preterm infants in the NICU.

My approach to feeding premature infants was fairly consistent until about 10 years ago when nurses in Edmonton, Alberta (in a level II unit) introduced me to “semi-demand” feeding.  What I find interesting about this, is the paucity of evidence that existed on the subject.  At the time, the evidence really centred around one paper but the impact of the approach was undeniable.  In 2001 McCain et al published the randomized controlled trial involving 81 infants A feeding protocol for healthy preterm infants shortens time to oral feeding.  The concept of semi-demand feeding was to assess each infant (once preterms reached 32-34 weeks CGA) before a feed for signs “of feeding readiness”.  This was accomplished through offering non-nutritive sucking every three hours before a scheduled feed.  If the infant was found to be in a wakeful state, the oral feeding was commenced but otherwise the infant was left for 30 minutes with NNS attempted again.  If the infant was still not ready then a gavage would be given.  The key here is that the infants were monitored for signs of feeding readiness rather than insisting upon an arbitrary time for their next feed.  The study findings were a halving of the time it took to reach full feeds (10 days in control vs. 5 days in semi-demand) with no difference in weight gain observed between groups.  The latter point is worth emphasizing, as the concern with semi-demand has been from some that in a worst case scenario where feeds took place every 3.5 hours a baby would miss one feed compared to another infant on a q3h schedule.  This fear though does not bear out in the study.

The experience in the centre I currently work at has been so positive that it is hard to find a patient that is not fed in such a way whether a physician orders the approach or not!  What is truly fascinating to me is how effective the approach seemingly is and has been adopted again with very little evidence compared to that traditionally needed to change a practice in the neonatal world.  Interestingly, although we can’t say for sure we have noticed year over year declines in length of stay for infants born with a birthweight of 1500 – 2000g since the introduction of semi-demand feeding.  This could be a coincidence as this has not been the only practice change in our units but it certainly is interesting.

I was delighted to see a paper published this week on the topic by Wellington and Perlman.  This was a Quality Improvement project entitled Infant Driven Feeding in Premature Infants: A Quality Improvement Project.  This study compared three periods.  The first was one in which physicians set the feeding schedule (PDF), the second a training period for a new system and the last the infant driven period (IDP).  In the PDF phase, the physicians would order one oral feed a day, then two, three and so on when the full feed was attained at each prescribed level.  In the IDF period an assessment sheet for feeding readiness would be completed before each attempt and the decision to offer an oral feed based on the perceived ability to feed at that time.


While this study was not an RCT it is a much larger group of patients than the study by McCain.  This comparison was between 153 PDF vs 101 IDF patients.  Feeding readiness assessments would start at 32 weeks CGA but feedings would not be offered by either approach until 33 weeks CGA similar to our own approach to feeding for the most part.  The use of IDF made no difference to timing of first attempt at nipple feeding.  The time to attain full nipple feeding was where significant differences in approach became apparent.

Time to reach full nipple feeding by gestational age at birth:

<28 weeks: IDF versus PDF group reached full NF 17 days sooner (374/7 vs 40 weeks; p=0.03)

28316/7: IDF versus PDF group reached full NF 11 days sooner (35 4/7 vs 37 1/7 weeks; p<0.001)

32 weeks: IDF versus PDF group reached full NF 3 days sooner (354/7 vs 351/7 weeks; p=0.04).

Affect on discharge

<28 weeks GA, no difference between the IDF versus PDF group (41 3/7 vs 39 4/7 weeks; p=0.10).

28316/7 weeks GA, IDF group were discharged 9 days earlier (366/7 vs 381/7 weeks; p<0.001).

32 weeks GA, the IDF group were discharged 3 days earlier (36 weeks vs 363/7 weeks;


Although the findings are clear there does need to be the usual acknowledgement that this is not the gold standard RCT but the practice change in the unit was done pretty carefully.  The concept is one that makes a great deal of sense regardless.  The lack of difference in discharge for the smallest infants makes some sense as it may well be apnea of prematurity that is the last to resolve.  There is no disputing however the benefit in earlier discharge for the 28 – 31 6/7 week group.  They achieve feeding earlier and go home faster.  From a family centred approach this is the best of both worlds.  One should not write off the use of this technique in the smallest infants either as they will have their care normalized much earlier with the NG tube being removed and the parents getting to participate and practice feeding much earlier in their course. Although not measured in this study, it would be intriguing to look at the number of patients who were admitted to hospital post discharge with failure to thrive.

Imagine the impact as well on hospital length of stay data if you multiple the reductions in length of stay by the total number of patients seen in these gestational age categories each year.  This almost certainly can represent over a year of patient days for many hospitals.

As I see it the direction is clear.  We should not force our premature infants to follow a schedule that works for us.  Rather use the cues that only they can provide to tell us when and how much milk they desire.  Both the parents, infants and our hospitals will benefit.

Bressure, Lactavists and Brelfies

Bressure, Lactavists and Brelfies

Nineteen seventy two was notable for many things aside from the year of my birth.  Canada defeated the Soviets in the summer series, the Watergate scandal took down a Presidency, The GodFather was released and for the purposes of this post breastfeeding rates in the US reached an all time low of 22%.  For an excellent review of the history of breastfeeding the article by AL Wright is excellent.BF rates

Rates of breastfeeding began a steady decline in the 1960s as more and more women entered the workforce and seemingly had to choose between employment and breastfeeding.  This was a time when it was not seen as being acceptable to breastfeed in public (although that is not the case in many places still to this day) and the workplace was not as conducive to supporting women as in current times (think onsite daycares).  Add to this that the 1970s also saw a backlash of sorts in the appeal of breastfeeding due to science “perfecting” a better source of nutrition in formula and we had the low rates that we did.  In fact through discussions with parents from that generation, mother’s who chose to breastfeed may have been viewed by some as being silly for not using something like formula that could let the whole family in on the experience.  Mom, Dad, kids and grandparents could all take part in the wonderful act of feeding.  Why be so selfish?

Following this period as research began to demonstrate improved outcomes with breastfeeding including reductions in atopic disease, less hospital admissions and more recently positive impacts on intelligence and your microbiome the trend reversed. In fact, as the above graph demonstrates, rates approximating 70% were reached by the late 1990s.  Since that time the CDC has shown that initiation rates have continued to rise and currently are at the highest documented levels in history.

Screenshot 2015-06-01 00.38.37

Looking at the CDC data though reveals some very important information.  While the rates of any breastfeeding reach 80%, the rates at 6 months hover around 50%.   This means that a significant portion of US women are using some formula when they come home and from the graph on the right about 35% by three months are exclusively breastfeeding. This number is far short of the goal the WHO has set to encourage exclusive breastfeeding for the first 6 months however it is a remarkable achievement for infant health.

A recent trend on social media and print media has been the Brelfie.  As you may know, this involves taking a picture of yourself breastfeeding your baby and posting it in one forum or another.  This has been popularized by many celebrities and made it’s way onto the cover of Elle magazine this month.

CF8PngLVAAMCIoSSo called Lactavists have been overjoyed to see such public acceptance and promotion of breastfeeding.  As a Neonatologist I am delighted to see such high rates of breastfeeding and with it the beneficial effects that it brings.

Curiously, though all of this attention and promotion of breastfeeding has created a culture that is now being called bressure.  This is defined as pressure to breastfeed and was the subject of a recent survey by Channel Mum in the UK.  The highlights of the survey that went out to  2,075 mums showed:

–  16 per cent of bottle-feeding mums have been on the receiving end of cruel comments from other mothers they know

 – one in 20 being attacked on social media

 – 69 per cent of bottle-feeding mums said they had been judged negatively

–  41 per cent made to feel they have ‘failed as a mum and failed their child’ by not breastfeeding

–  15 per cent of mums have even lied to cover up their bottle-feeding and appear to be ‘better’ mums.

This so called bressure has led to a public campaign to increase awareness of the harassment that some mothers feel which involves taking selfies with cards having one word describing what breastfeeding meant for them.  A video from Channel Mum can be seen here

Channel Mum Video Response to Brelfies

While I am all for breastfeeding, I find it peculiar that the experience that breastfeeding mothers (all 22% of them) had in 1972 is now being felt by a larger percentage in 2015 who are bottle feeding.  It is unfortunate that assumptions are being made of many of these women who put a bottle in the mouths of their infants.  How many times does one conclude that the mother simply chose not to breastfeed because they were worried about the way their breasts would be affected cosmetically or that they simply chose to go back to work and breastfeeding would just get in the way.  I suspect in most cases the truth is much different.  Many of these mothers have tried to breastfeed but couldn’t produce enough.  Others may have suffered from cracked nipples, mastitis, abscesses or due to prior surgery were unable to produce milk.  Many such mothers have agonized over their “failure” to do something that they hear “everyone can do”.  While they are told it takes some work for many that is a huge understatement.  Is it not bad enough that these women have suffered the feeling of failure?  To be looked at or spoken to in a disapproving way does nothing to support them.  Add to this that by 3 months of age at least in the US 65% of mothers are providing some formula and it seems silly to take the “high and mighty” approach in the first couple of months and assume the worst of these women. Many of the “breastfeeders” will soon enough join the ranks of those using some formula.

Maybe the better option is to try and help.  Many of the above problems whether it be producing enough quantity or pain related to breastfeeding can be addressed through tips on technique.  While I am not an expert in this, hospitals would do well to increase staffing of on site lactation consultants to help mothers who wish to breastfeed get off on the right foot so to speak.  A larger working force of midwives in North America in particular could certainly provide help in this regard.  What I can say is that if a woman suffers a bad experience with breastfeeding in their first pregnancy the likelihood they will try again the next time is lower especially if we as a society make them feel like a failure.

Yes we need to promote breastfeeding and we should do what we can to follow the WHO recommendations and minimize the use of formula when possible.  While bressure may have been intended to yield something good we need to be sensitive.  Perhaps a better strategy next time a friend says they are going to use formula is to ask if they are having trouble with breastfeeding and if they need some help. Not having the discussion will ensure that nothing changes and a chance to do something will be lost due to misdirected bressure.

Glucose gel For Managing Hypoglycemia.  Can We Afford Not To Use It?

Glucose gel For Managing Hypoglycemia. Can We Afford Not To Use It?

I was inspired to write this post after sharing a review of an article from 2013 on my Facebook page. The article pertained to the use of a 40% dextrose gel to treat neonatal hypoglycemia

We have been using this glucose gel in our population for nearly two years and have noted great success in avoiding admissions for hypoglycemia, however this remains unpublished. I was surprised to hear how many places have yet to adopt such treatment and based on the comments on the page it would appear that adoption of such gels are on their way in some locations. The popularity of this post though inspired me to write this piece, which summarizes the evidence for the use of gels in the neonate.

What is the Evidence For Using Glucose Gels

Surprisingly there is actually very little in the way of publications on the topic. In 1992, there was a small randomized trial which failed to show a benefit in terms of variability of one serum glucose to the next but it did not look at other functional outcomes such as impact on maternal infant separation or success in breast-feeding.

The next study is in fact the one mentioned in the article that was posted on Facebook called the Sugar Babies study. Dr. Harris in this case studied 118 infants who received 40% dextrose gel vs 119 who received a placebo gel. All of the infants in this study were selected based on risk factors for hypoglycemia (IDM, IUGR, LBW, LGA, near term) and were all 35 weeks or greater. Each infant had to be less than 48 hours of age when enrolled. Infants received 0.5 mL/kg 40% dextrose gel (200 mg/kg). This was designed to deliver the same amount of sugar as would be given with a D10W bolus of 2 mL/kg. In order to receive the treatment the blood glucose had to be < 2.6 mmol/L so equivalent to our own standards in Canada and the US. Treatment failure, which was the primary outcome was defined as a blood glucose < 2.6 mmol/L despite two treatments with gel. The significant findings were quite interesting and are shown in the table below.

Finding Dextrose Placebo
Treatment Failure 14% 24%
Admission to NICU 14% 25%
# formula feeds (median) 7 10
Formula fed at 2 weeks 4% 13%

What was not found to be significant and in and of itself is a very important finding is a higher incidence of rebound hypoglycemia in the dextrose gel group. This was a potential concern as provision of dextrose in theory could cause a spike in insulin secretion thereby dramatically lowering the blood glucose but thankfully this was not observed.

Dextrose Gel Improves Breastfeeding Rates

These results I believe speak for themselves but it is extremely important to highlight the benefit here. The use of the dextrose gel was also able to enhance success at breastfeeding rates. This was accomplished in all likelihood by a reduction in admission to NICU and less reliance on formula to achieve satisfactory blood glucose. As these infants were all less than 48 hours old it is safe to assume that in many cases the mother’s milk had not yet come in so if the glucose measured was low, health care providers were more likely to intervene with an offering of formula.  It is worth noting that while this is the only significant study in the field there is a letter to the editor in which another author describes the use of a sublingual sugar powder for treating the same, which was met with similar success. There is no actual peer-reviewed study to examine however so we will leave it as simply an interesting point.

New Study on The Way

If these results leave you still being skeptical you may be pleased to hear there is a very large study (2129 babies needed) beginning enrolment in New Zealand with the primary outcome of admission to the NICU.  This prospective RCT will hopefully put to rest any questions about this treatment that have delayed implementation in many units.

As a final thought regarding the Sugar Babies study, one of the differences that came close to reaching statistical significance was the rate of IV insertions for dextrose. In the dextrose gel group the rate was 7% vs 14% in the placebo. With a p value of 0.09 it suggests that with a larger study size a difference may have been reached. The idea that we have the option of using a therapy that can decrease formula use, improve breastfeeding rates including those found post discharge and lastly decrease the poking of infants for IV dextrose is a goal well worth pursuing. Is this enough evidence for you? I would encourage all who read this piece to ask their NICU the question of whether a trial of dextrose gel is worthwhile. It could make a big difference far beyond treating a number.
