Feeding Infants with Neonatal Abstinence Syndrome: Finding the Sweet Spot

Verbal Behavior of Mothers With Opioid Use Disorder While Feeding Infants With Neonatal Opioid Withdrawal Syndrome

BACKGROUND

An infant's cognitive development is highly dependent on early interactions with its primary caregiver, often its mother. Feeding, a frequent and early exchange between mothers and infants, is an important time for maternal-infant bonding. Mothers with opioid use disorder have been found to be more physically and verbally stimulating and more active during feeds than mothers with no opioid use.

PURPOSE

The purpose of this study was to describe the characteristics of verbal interactions mothers with opioid use disorder expressed while engaged in a feeding encounter with their infant undergoing treatment for neonatal opioid withdrawal syndrome to offer insight into maternal experiences and potential challenges of feeding infants experiencing withdrawal.

METHODS

A qualitative descriptive analysis of maternal verbalizations during the feeding was used in a secondary analysis using the Barnard Model as the theoretical framework for maternal-infant interaction.

RESULTS

A theory-driven deductive approach was assumed to organize the identified subthemes within the concepts of the Barnard Model. Mothers frequently commented on hunger, satiation, and stress cues, while providing consolation, praise, and encouragement. Mothers expressed concerns regarding feeding volume and pace, and consequences related to feeding.

IMPLICATIONS FOR PRACTICE AND RESEARCH

It is crucial that clinicians remember that feeding is an important time for maternal-infant bonding. Further research into the feeding interactions of mother-infant dyads with opioid exposure is warranted. As infants may present with subacute signs of withdrawal, including persistent feeding difficulties for months, further investigation into feeding challenges dyads experience after discharge from the hospital is needed.

Factors Associated with Maternal Engagement in Infant Care When Mothers Use Substances

Introduction

Mothers who use substances can play a key role in the treatment and care of their infants. However, challenges exist to engaging these mothers in the care of their infant. The purpose of this study was to identify factors associated with maternal engagement in infant care when mothers are experiencing substance use disorders.

Materials and Methods

A systematic search was conducted using the databases of CINAHL, APA PsycINFO, and PubMed along with a manual search of Google Scholar between the years of 2012 and 2022. Studies were included if they were (1) original qualitative research; (2) published in English; (3) peer reviewed; (4) from the perspective of mothers who use substances or nurses; (5) included descriptions of interactions between mothers who use substances and their infants during postpartum care, and/or in the nursery or neonatal intensive care unit; and (6) conducted in the United States. The studies were assessed for quality and validity using 10 criteria from the Joanne Briggs Institute critical appraisal checklist for qualitative research.

Results

Findings from 22 qualitative studies were synthesized using a thematic synthesis approach and revealed 3 overarching themes that included 7 descriptive subthemes that identified factors to maternal engagement. The seven descriptive subthemes included: (1) Attitudes Toward Mothers Who Use Substances; (2) Knowledge on Addiction; (3) Complicated Backgrounds; (4) Emotional Experiences; (5) Managing Infant Symptoms; (6) Model of Postpartum Care; and (7) Hospital Routines.

Discussion

Participants described stigma from nurses, complex backgrounds of mothers who use substances, and postpartum models that influenced mothers' engagement in infants' care. The findings suggest several clinical implications for nurses. Nurses should manage their biases and approach mothers who use substances in a respectful manner, increase their knowledge of issues and care related to addiction in the perinatal period, and promote family-centered approaches to care.

Conclusion

The findings of 22 qualitative studies described factors associated with maternal engagement in mothers who use substances that were integrated using a thematic synthesis method. Mothers who use substances have complex backgrounds and experience stigma which can negatively impact their engagement with their infants.

Early Weight Loss Percentile Curves and Feeding Practices in Opioid-Exposed Infants

OBJECTIVE

We examined weight loss patterns and feeding practices of infants hospitalized for neonatal opioid withdrawal syndrome (NOWS) managed by the eat, sleep, console approach, which emphasizes nonpharmacologic treatment. Although feeding practices during hospitalization vary widely, weight loss patterns for infants managed under this approach have not yet been described.

METHODS

Of 744 infants with NOWS born from 2014 to 2019 at our institution, 330 met inclusion criteria (≥35 weeks' gestation and no NICU transfer). We examined maximum weight loss and created weight loss percentile curves by delivery type using mixed effects quantile modeling with spline effect for hour of life; 95% confidence intervals (CI) were compared to published early weight loss nomograms.

RESULTS

In the cohort, the mean gestational age was 39.2 weeks, mean birth weight was 3.1 kg, and mean length of stay was 6.5 days; 94.6% did not require pharmacologic treatment. Median percent weight loss was significantly more compared to early weight loss nomograms for both vaginally-delivered infants at 48 hours (6.9% [95% CI: 5.8-8.5] vs 2.9%) and cesarean-delivered infants at 48 hours (6.5% [95% CI: 4.1-9.1] vs 3.7%) and 72 hours (7.2% [95%CI 4.7-9.9] vs 3.5%), all P < .001. Overall, 27.9% lost >10% birth weight.

CONCLUSIONS

We demonstrate weight loss patterns of infants with NOWS managed by the eat, sleep, console approach at a single center. Infants with NOWS lose significantly more weight than nonopioid exposed infants and are at increased risk of morbidity and health care use. Studies to address optimal feeding methods in these infants are warranted.

A Meta-Analysis of Breastfeeding Effects for Infants With Neonatal Abstinence Syndrome

Supplemental digital content is available in the text.

Background

Neonatal abstinence syndrome (NAS) rates have dramatically increased. Breastfeeding is a nonpharmacological intervention that may be beneficial, reducing NAS symptom severity and thus the need for and duration of pharmacological treatment and length of hospital stay.

Objectives

Conduct meta-analysis to determine whether breastfeeding results in better outcomes for NAS infants. Variables included symptom severity, need for and duration of pharmacological treatment, and length of hospital stay.

Methods

PubMed, Scopus, Embase, and Cochrane Library were searched from 2000 to 2020, and comparative studies examining breastfeeding for NAS infants were extracted. Randomized trials and cohort studies were included. Data were extracted and evaluated with Review Manager Version 5.3. A random-effects model was used to pool discontinuous outcomes using risk ratio and 95% confidence intervals. Continuous outcomes were evaluated by mean differences and 95% confidence intervals.

Results

Across 11 studies, 6,375 neonates were included in the meta-analysis. Using a random-effects analysis, breastfeeding reduced initiation of pharmacological treatment, reduced duration of pharmacological treatment, and reduced length of stay. No differences were detected for severity of NAS symptoms. Most studies only reported one to two variables of interest. For most studies, these variables were not the primary study outcomes. All studies were found to be of low risk and good quality based on the Cochrane Risk Assessment Tools. Varying breastfeeding definitions limit generalizability.

Discussion

Breastfeeding is associated with decreased initiation and duration of pharmacological treatment and length of stay.

A Review of Feeding Practices in Infants With Neonatal Abstinence Syndrome

BACKGROUND

There has been an increase in infants with neonatal abstinence syndrome (NAS) in neonatal intensive care units (NICUs) over the past several decades. Infants with NAS experience withdrawal as a result of the sudden termination at birth of substance exposure during pregnancy. A serious sign related to infants diagnosed with NAS is poor feeding. The prevalence of NAS urges researchers and clinicians to develop effective strategies and techniques to treat and manage the poor feeding of infants exposed to substances in utero.

PURPOSE

To synthesize current feeding methods and practices used for infants diagnosed with NAS.

METHODS/SEARCH STRATEGY

PubMed, CINAHL, and Scopus were searched for articles published within the last 20 years that focused on feeding practices or feeding schedules, were written in English, were peer-reviewed, and described human studies. The search terms utilized were "neonatal abstinence syndrome" OR "neonatal opioid withdrawal syndrome" AND "feeding."

FINDINGS/RESULTS

Three findings emerged regarding techniques and management of poor feeding in the NAS population. The findings included infants who received mother's own milk had decreased severity and later onset of clinical signs of withdrawal, demand feeding is recommended, and the infant's cues may be helpful to follow when feeding.

IMPLICATIONS FOR PRACTICE

Clinicians should encourage mother's own milk in this population unless contraindications are present. Caregivers and clinicians must be receptive to cues when feeding infants with NAS.

IMPLICATIONS FOR RESEARCH

Even with the clinical knowledge and experience that infants with NAS are difficult to feed, there is limited research assessing techniques and schedules that are effective in managing successful feeding. Future research should compare feeding schedules such as on-demand feeding versus regimented feeding schedules, as well as investigate techniques that mothers and nurses can utilize to encourage oral intake in this population.Video abstract available at https://journals.lww.com/advancesinneonatalcare/Pages/videogallery.aspx?autoPlay=false&videoId=37.

Feeding Behaviors in Infants With Prenatal Opioid Exposure: An Integrative Review

BACKGROUND

Oral feeding is one of the most complex maturational skills of infancy. Difficulties with feeding require specialized attention, and if not well managed, may prolong the newborn's hospital length of stay. This is particularly true for prenatally opioid exposed (POE) infants. A paucity of literature exists characterizing feeding behaviors of POE infants, yet feeding problems are common.

PURPOSE

The purpose of this integrative review was to synthesize and critically analyze the evidence that characterizes feeding behaviors in full-term, POE infants.

METHODS/SEARCH STRATEGY

The electronic databases of CINAHL, PubMed, Scopus, and PsycINFO were used. Inclusion criteria were studies in English, conducted from 1970 to 2019, with participant samples consisting of infants with prenatal opioid exposure, born full-term, and between 38 and 40 weeks of gestation. Based on the inclusion criteria, our search yielded 557 articles. After further screening, only 4 studies met our full inclusion/exclusion criteria. These studies were analyzed for evidence of infant feeding behaviors, including characterization of problematic feeding behavior for POE infants.

FINDINGS/RESULTS

Our findings revealed inconsistencies in characterization of feeding behaviors among POE infants. A synthesis of the most common evidence-based behaviors was constructed. Infant feeding behaviors were identified and grouped into 2 major behavior domains: (1) typical feeding behavior and (2) problematic feeding behavior.

IMPLICATIONS FOR PRACTICE AND RESEARCH

Feeding behaviors related to sucking and behavioral states may be different in POE infants. Further examination of effective assessment methods and the categorization of infant feeding behaviors are warranted for use in the development of evidence-based, targeted intervention.

The Joys and Frustrations of Breastfeeding and Rooming-In Among Mothers With Opioid Use Disorder: A Qualitative Study

OBJECTIVES

To investigate perspectives of mothers with opioid use disorder regarding breastfeeding and rooming-in during the birth hospitalization and identify facilitators and barriers.

METHODS

We conducted in-depth qualitative interviews with 25 mothers with opioid use disorder 1-12 weeks after delivery. Grounded theory analysis was used until thematic saturation was reached. Findings were triangulated, with experts in the field and a subset of informants themselves, to ensure data reliability.

RESULTS

Among 25 infant-mother dyads, 36% of infants required pharmacologic treatment, 72% of mothers initiated breastfeeding, and 40% continued until discharge. We identified the following themes: (1) information drives maternal feeding choice; (2) the hospital environment is both a source of support and tension for mothers exerting autonomy in the care of their infants; (3) opioid withdrawal symptoms negatively impact breastfeeding; (4) internal and external stigma negatively impact mothers' self-efficacy; (5) mothers' histories of abuse and trauma affect their feeding choice and bonding; (6) mothers' recovery makes caring for their infants emotionally and logistically challenging; and (7) having an infant is a source of resilience and provides a sense of purpose for mothers on their path of recovery.

CONCLUSIONS

Future interventions aimed at increasing breastfeeding and rooming-in during the birth hospitalization should focus on education regarding the benefits of breastfeeding and rooming-in, supporting mothers' autonomy in caring for their infants, minimizing stigma, and maximizing resilience.
