Problem Solving: NICU infants with GER

QUESTION: I have two infants that I am currently treating who were both preemies one extremely premature and one late-preterm. However they are both showing similar s/s that seem to be cues of bigger issues that are not clear to anyone right now. Would love some open discussion and feedback.Both have had VFSS which showed some oral disorganization however pharyngeal stages looked decent organizing in valleculae at appropriate ages. Both babies have been worked up by pediatric GI with suspected milk allergy and are on Nutrimagen.

Taught families to read baby’s cues as first tasks in plan of care and addressed nipple flow rates. One baby with similac slow flow and other with haberman. Both babies take on average one ounce and stop which is a good feed. Some feeds all feed is gavaged due to crying and fussing to point of exhaustion.

Had parents swaddling babies for first several months and now older baby still likes swaddle at time and younger baby is in phase where as soon as mom swaddles she begins to fight and scream.
Both babies have had EGD with no remarkable findings other than which we already knew GERD/EER. Both babies on appropriate H-2 blocker for reflux.

I have had several colleagues comment that they have had similar cases in past and never felt they got anywhere and I just can’t except the we don’t know answer. These two girls cases will drive me crazy until we find the right combination for them as you would expect they both show significant aversions to each and every feed and parents report their best feeds are the “dream feeds”. I would love whatever input is out there to help me continue to piece these girls puzzles together. Thank you!!!

ANSWER: It sounds as though GER/EER may indeed be part of the picture. it is helpful that they did an EGD to ruleout Eosinophilic Esophagitis; not often done in NICUs. That at least tells us that positive intervention strategies due to GI issues will include: frequent burps, not allowing gulping, reducing air swallowing and smaller more frequent feedings, all of which will help these preterms.

The specifics of the post don’t mention GA or current PCA for either infant but we know one is extremely preterm (so I am thinking at or under 28 weeks GA) and one is a late preterm. We know from the literature that the extremely preterm infant is profiled as a high risk fragile feeder due to her co-morbidities, which include very likely respiratory co-morbidities. For her, that may be a bigger influencing factor than the EER. There is the potential for increased WOB and intermittent tachypnea at baseline , and then a subsequent increase in both due to the aerobic demands of feeding, with resulting respiratory fatigue. Her signs of disengagement (i.e., signalling she is done via not rooting or not continuing to suck) may indeed be driven by respiratory issues as much as the effects of EER. Your description of her recent feeding behaviors strongly suggests a primary respiratory issue adversely affecting feeding. I’d tend to stay away from thickening as it has its own adverse sequelae in neonates and stay with effective “co-regulated” external pacing combined with a slow controllable flow rate, sidelying and respect for infant’s signs of engagement and disengagement. Sounds like you are already doing that. Depending on her history, asking/expecting her to take all feeds PO may be beyond her capacity to do so. Caregivers who, with good intentions, “feed past her stop signs” with a focus on “volume-driven” versus “infant-guided” feeding experiences may indeed reinforce negative learning and wire those neural pathways which will ultimately move her “away from” the desire to feed.

The late preterm infant, surprisingly, is in a group, “late preterms”, who, according to the most recent literature, are more likely to be re-admitted for poor feeding than extremely preterm infants. That is because they too have the key co-morbidities, which often get less notice as they are perceived as “a little newborn” by some caregivers. These co-morbidities include respiratory, due to immature lungs and RDS (although more subtle than infants of younger GA)but still adversely affecting coordination and drive to feed. In addition, their other common co-morbitidites often include decreased postural control, hypoglycemia and jaundice, and reduced state regulation (all of which can reduce drive to feed and result in poor endurance and suboptimal intake). Re-alerting strategies are important for this group, as is controllable/slow flow and co-regulated external pacing in a swaddled sidelying positon.

The infant you mention below, whom you fed at 9-12-3 sounds as if she may be the former extremely preterm infant. Her adverse overt behavior of coughing, combined with uncoupling of breathing and swallowing (reflected in gulping, eyebrow raise, eyebrow furrowing and movement into extension) suggest the workload may be beyond her skill level and she may be becoming an unsafe feeder at times, despite having no bolus mis-direction during the VFSS. Look to see if feeders are truly offering co-regulated external pacing; her adverse behaviors you mention below suggest a need for better co-regulation, i.e., breaks could perhaps be offered more contingent on her signs of impending incoordination, to avert stress behaviors by facilitating a stable burst-pause pattern and better swallow-breathe synchrony.

Helping all caregivers recognize that we cannot push preterms beyond their capacity is critical. I think you are providing wonderful infant-guided support. Be careful to not get pulled into the “volume means success” mantra that for years was the guide in the NICU. Both infants, from the limited description, are preterms who may not be able to be full PO feeders in the near future, but they can be supported to have positive experiences no matter what amount they take.

Problem Solving: VFSS orders from GI docs

We have a pediatric GI doc who is very fond of ordering MBS’s (and every other test possible). In the last 5 years he has practiced at this hospital I have seen 4 of his patients actually aspirate. Most already have a dx of reflux. Because I work IP and do not do a ton of long-term feeding tx I was wondering if these MBS’s are helping anyone – particularly OP SLP’s who treat.

Answer: I think the GI docs are actually asking us to help them complete a differential, that is, to rule out if s/s the child presents might be a true dysphagia. It may be that the etiology for the s/s is indeed GI-related, but I have had pediatric patients referred by GI docs for VFSS who have both a GI-related etiology and a true dysphagia co-occurring, and also those for whom the etiology is indeed only dysphagia, though it appeared GI-related prior to the VFSS. The physician’s thoughtful use of the VFSS to assist with a differential is good and should be welcomed by those of us who work with children who present feeding/swallowing problems. To the extent that a good differential is completed, by us and by the doc, our plan of care will be more appropriate. Even if a child does not aspirate, the information about the physiology of the swallow and any bolus mis-direction, and its etiology(ies), is useful information. As Bonnie Martin-Harris has said, “Aspiration or penetration is neither necessary nor sufficient for a swallowing impairment”, meaning the value of /data from a VFSS is far greater than just a pass/fail rating.

Shaker Webinar on Passy-Muir Valve in the NICU to Optimize Swallowing and Feeding

Shaker Webinar on Passy-Muir Valve in the NICU to Optimize Swallowing and Feeding 

This webinar will highlight the key components of Passy-Muir Valve use in the Neonatal Intensive Unit (NICU) for swallowing and feeding. Limited information is available in the literature about application of the valve in this setting. The presenters will describe their journey, share their key clinical leanings and the positive response in their NICU. The fragile nature of these patients, combined with limited knowledge on the part of medical/nursing staff regarding the benefits of the Passy-Muir Valve, require a thoughtful and team-oriented approach. The clinical benefits for using the valve for swallowing and feeding will be reviewed. Functional changes during instrumental assessments with the valve will be highlighted.

Shaker Publication on moving away from volume-driven feeding

“Feed Me Only When I’m Cueing: Moving Away From a Volume-Driven Culture in the NICU” published in the May-June 2012 issue of Neonatal Intensive Care –The Journal of Perinatology-Neonatology.

Abstract: The adverse feeding  outcomes of NICU graduates and their enduring feeding problems suggest a need  to critically look at  “the culture of feeding” in the NICU. It is a pivotal factor in how the preterm experiences feeding , how parents develop their working model of the feeding  relationship, and how the NICU  team communicates about,  and attempts to support,  feeding skills needed for discharge to home. These cultural underpinnings can affect caregiving, both adversely and positively, and, therefore, the emergence of safe and successful feeding and  swallowing.  An “infant-driven” culture of feeding (Ludwig & Waitzman, 2007) embraces the infant as a co-regulatory partner. A more traditional “volume-driven” feeding culture focuses on emptying  the bottle. An Infant-driven culture is suggested as essential for a true cue-based feeding approach, which optimally supports the preterm infant’s developmental strivings and long-term well-being.

Together, we can help change the culture of feeding in the NICU.

Problem Solving: Infants with congenital heart disease

Question: “I recently evaluated a one month old baby with ASD and VSD for a feeding evaluation. His mother reported coughing during meals and some reflux. He bottle and breast feeds, uses a nipple shield for breast feeding. He has a strong suck but is disorganized. Sucking bursts vary from 25 to 7 to 15, etc. Liquid extraction is good. He did exhibit some reflux during the feeding but no coughing. I am going to return for a second feeding next week. I have been researching the effects of ASD and VSD on feeding and have found that they tend to be poor feeders. I am wondering if this is because of the breathing difficulties they tend to have. He did not exhibit any breathing difficulties during the feeding. Has anyone had experience with this diagnosis? His reflexes are good. He does have an upper attached lip frenulum with some tightness of the upper lip. He appears to have a good latch and has a non-nutritive suck although he really doesn’t like his pacifier.”

Answer :
Infants with an ASD and/or VSD typically do have increased work of breathing and tachypnea. These compensatory behaviors may be overt or subtle. It is also challenging if one is not used to looking at these types of behaviors to necessarily “see” them.

His long sucking bursts are highly likely to be adverse. They keep him from stopping often enough to deep breathe. Deep breaths which re-saturate the blood with oxygen are critical for babies with heart defects. Long bursts of sucking without deep breaths then deplete his respiratory reserves, causes him to all of a sudden need to inhale (even if he is in the middle of a swallow) and can result in the coughing you report. Unfortunately, most events of aspiration are silent in infants, as the cough reflex is unreliable, especially at his age, so he may be compromising his airway more than is overtly apparent.

It may help you to gain support for assessing respiratory work during feeding (and at rest) in infants to pair up with another SLP who can look along with you at the cardiorespiratory symptoms that he may be displaying.

In the meantime, I’d switch him to a slow flow nipple, feed in swaddled sidelying to reduce work of breathing, avoid any prodding or passive manipulation of the nipple to “prompt” him to suck if he stops to breathe, and provide vigilant external pacing to limit the number of sucks in a row based on his “continuous feedback” from moment to moment.

To help you regarding what “cues” signal a need for a pause from sucking, and best supportive interventions, see: Shaker, C.S. Nipple feeding preterm infants: An individualized, developmentally supportive approach.1999. Neonatal Network, 18(3) 15-22. Even though the focus in that article is on preterms, it provides a good explanation of infant cues (signs of stress versus stability) that may be observed secondary to the cardio-respiratory work which is part and parcel of feeding.

Infants with an ASD or VSD are likely to become uncoordinated and exhibit respiratory fatigue, which can increase as the feeding progresses, due to the aerobic demands of feeding. It will be important to protect the infant and to help parents understand that slowing him down in the long run will better help him “go the distance”
