Eating as a neurodevelopmental process for high-risk newborns

Relationship between prematurity and difficulties in the transition of food consistency in childhood: a systematic review

PURPOSE

To systematically review the literature regarding the impact of prematurity on the transition of food consistencies in infants during the introduction of complementary feeding.

RESEARCH STRATEGIES

Searches were conducted in the EMBASE, Latin American and Caribbean Literature in Health Sciences (LILACS), LIVIVO, PubMed/Medline, Scopus, and Web of Science databases, Google Scholar; for gray literature, searches were conducted on Open Gray, and ProQuest Dissertations & Theses databases, from August 10, 2020, onwards.

SELECTION CRITERIA

"PECOS" was selected to determine inclusion criteria: Population (P): Infants; Exposure (E): Prematurity; Comparison (C): Full-term newborns; Outcomes (O): Progression of food consistencies in premature newborns with or without comparison; Study design (S): Cohort study, Case-control; Cross-sectional.

DATA ANALYSIS

The methodological quality of the selected observational studies was assessed using the Meta-Analysis of Statistics Assessment and Review Instrument (MASTARI).

RESULTS

A total of 3,310 articles were found, of which nine were selected for qualitative synthesis. Among the selected studies, a relationship between invasive oral interventions and feeding difficulties was observed for all assessed skills, with feeding difficulties being more frequent in infants with lower gestational age.

CONCLUSION

Most studies found no significant relationship between prematurity and difficulties in the progression of food consistencies during the introduction of complementary feeding; only three studies demonstrated such a relationship.

Relationships between preterm medical factors and feeding behaviors at term-equivalent age

AIM

To identify relationships between early medical factors and preterm infant feeding behaviors at term-equivalent age.

METHODS

Forty-three very preterm infants born ≤32 weeks gestation had standardized feeding assessments using the Neonatal Eating Outcome Assessment at term-equivalent age (36-42 weeks postmenstrual age). Medical factors were collected and analyses were run to determine if associations between different medical factors and feeding performance exist.

RESULTS

Lower Neonatal Eating Outcome Assessment scores at term-equivalent age were associated with lower estimated gestational age (p < .01), lower birthweight (p < .01), older postmenstrual age at discharge (p < .01), longer length of stay in the neonatal intensive care unit (p < .01), chronic lung disease (p = .03), as well as more days on total parenteral nutrition (p = .03), endotracheal intubation (p < .01), and noninvasive mechanical ventilation (p < .01).

CONCLUSION

More feeding problems are observed in infants born earlier, with longer hospital stays, and with complex medical courses. Knowledge of the association between these medical factors and feeding difficulties allows for identification of infants who may benefit from early, targeted interventions to optimize the feeding process.

Birth-related, medical, and diagnostic characteristics in younger versus older children with avoidant/restrictive food intake disorder (ARFID)

BACKGROUND

Although avoidant/restrictive food intake disorder (ARFID) presents the replacement and extension of feeding disorders of infancy and childhood, previous research into ARFID concentrated mainly on older patients. While birth-related characteristics play an etiologic role in feeding disorders, virtually nothing is known so far in ARFID. Therefore, the first aim of the study was to identify differences in birth-related characteristics in younger vs. older children with ARFID. Second, differences in physical and mental comorbidities, and third, diagnostic features between age groups were analysed.

METHODS

Among N = 51 in- and outpatient treatment-seeking patients, n = 23 patients aged 0-5 years (30% girls) and n = 28 patients aged 6-17 years (57% girls), with an interview-based diagnosis of ARFID were included. Data on the pre- and perinatal period and mental and physical comorbidities were derived from patients' medical records, while diagnostic criteria, main ARFID presentation, and sociodemographic variables were collected through diagnostic interview.

RESULTS

Significantly, younger patients with ARFID were born more often preterm and had more pre- and perinatal complications and a higher incidence of postnatal invasive procedures. Patients with ARFID aged 0-5 years presented significantly more physical comorbidities and conditions, especially congenital anomalies, while mental comorbidities, especially mood disorders, were significantly more common in patients with ARFID aged 6-17 years. No age differences were found for the distribution of diagnostic criteria and main ARFID presentation.

CONCLUSION

This is the first study which aimed to identify age-specific characteristics in patients with ARFID with potential relevance for diagnosis and treatment. Especially birth-related complications, including invasive procedures postnatally, may be associated with developing ARFID, highlighting the importance of a closer view on these potential risk factors of the disorder. Future research with longitudinal design and larger samples may allow more detailed information on further age-specific associations, symptom trajectories, and age-specific risk factors for ARFID.

Comparison of Effect of Feeding Premature Infants with Either Cup, Bottle, and Syringe on Transition to Breastfeeding, Breastfeeding Success, Weight Gain, and Duration of Hospitalization

Objective: This study was completed with the aim of determining the effect of cup feeding (CF), bottle feeding (BF), and syringe feeding (SF) methods on the transition to breastfeeding, breastfeeding success, physiological parameters, weight gain, and discharge duration for preterm neonates in the neonatal intensive care unit (NICU). Materials and Methods: The study was designed to be randomized, controlled, and single blinded. The study was completed with 102 premature neonates between 29-34 gestational weeks abiding by the case selection criteria receiving treatment and care in the NICU. The 1st group comprised premature neonates receiving CF, the second group received BF, and the third group received SF. For collection of data, the Premature Infant Descriptive Information and Monitoring Form, Bristol Breastfeeding Assessment Tool (BBAT), and Infant-Focused Feeding Scales (IFFS) were used. Results: Comparison of mean peak heart rate in the groups found that the BF group was significantly high (p = 0.047) and comparison of mean SO2 found that the SF group was significantly high (p = 0.000). Infants in the SF group were determined to have significantly higher BBAT scores compared to the infants in the BF and CF groups (p = 0.015). In addition, SF infants were determined to transition to full enteral feeding and breastfeeding in a shorter duration (p < 0.05). There were no significant differences between the groups for weight gain and discharge duration (p > 0.05). Conclusions: The SF method was determined to more positively affect breastfeeding success, transition to full breastfeeding duration, and vital signs compared to the CF and BF methods. In line with the results obtained in the study, the use of the SF method may be recommended to increase breastfeeding success of neonates, to shorten the transition to full breastfeeding and for stable physical parameters.

Associations between feeding and development in preterm infants in the NICU and throughout the first year of life

BACKGROUND

There is little published evidence regarding associations between feeding and development in preterm infants which could help identify infants most needing follow-up services.

AIMS

To determine if preterm infant feeding and development were predictable throughout the first year of life and identify associations with maternal factors, neonatal factors, and socioeconomic measures.

STUDY DESIGN

Prospective single-site study of the feeding and development of extremely and very preterm infants at three time points throughout the first year of life.

SUBJECTS

Infants <32 weeks gestational age were followed from neonatal intensive care unit (NICU) discharge (DC) until 12 months corrected gestational age (CGA).

OUTCOME MEASURES

Feeding and development were evaluated at NICU DC, 3 months and 12 months CGA. Maternal health, infant health, and socioeconomic measures were also recorded.

RESULTS

Significant differences were found between assessments for feeding and development at each of the three time points: NICU DC (p = 0.026), 3 months CGA (p = 0.001), and 12 months CGA (p = 0.000); however, no associations were found between feeding and development at NICU DC and 12 months CGA (p = 0.137). Of the maternal factors determined to be significant, none were consistent enough as to be considered relevant.

CONCLUSIONS

This study demonstrated that preterm infants with typical feeding and development at DC may go on to develop concerns in these areas, and those who scored abnormally at DC may perform typically during the first year of life. This study affirms the importance of NICU follow-up services to support feeding and development for all infants born <32 weeks gestation.

Effects of Swaddling During Bottle Feeding in Preterm Infants

BACKGROUND

Preterm infants have immature oral feeding skills, affecting length of hospital stay and long-term feeding outcomes. Swaddling has positive effects on pain and stress responses, state regulation, and physiological stability in preterm infants in the neonatal intensive care unit (NICU). Swaddling during bottle feeding may support preterm infant behavioral organization and oral feeding skills. Swaddling is used inconsistently during feeding in the NICU and has not been critically examined for effects on bottle feeding performance in preterm infants.

PURPOSE

To examine the effects of swaddling on bottle feeding quality and efficiency in preterm infants.

METHODS

A convenience sample of 30 infants born before 34 weeks of gestation was selected in an urban level IV NICU. Using an experimental, randomized crossover design, each infant was swaddled for one feeding and unswaddled for one feeding. Feeding efficiency was measured by rate and volume consumed. Feeding quality was examined by the Early Feeding Skills Assessment and frequency of physiological changes. Data were analyzed using dependent t tests and Wilcoxon signed rank test.

RESULTS

When swaddled, participants demonstrated significantly better scores on all related subtests of the Early Feeding Skills Assessment ( P ≤ .001). Infants demonstrated no difference in frequency of bradycardia or oxygen desaturations greater than 4 seconds. No significant differences were found in feeding efficiency outcomes.

IMPLICATIONS FOR PRACTICE AND RESEARCH

Swaddling can be used in the NICU to improve bottle feeding quality in preterm infants. Future investigation is needed on long-term effects of swaddling during bottle feeding on feeding performance, weight gain, and length of stay.

Clinical validation of the infant-driven feeding scales© in Turkey

BACKGROUND

Supporting the development of feeding skills among preterm infants is an important component of neonatal care. The selection of appropriate and supportive feeding interventions begins with a comprehensive assessment of the infant's skills.

PURPOSE

This study aimed to adapt the Infant-Driven Feeding Scales© (IDFS) to the Turkish language.

METHODS

This was a methodological, observational, single-center cross-sectional study. The study included 80 infants born at a gestational age ≥ 32 weeks, consecutively admitted to a tertiary Neonatal Intensive Care Unit (NICU). Research data were collected using a premature infant descriptive information form (IDIF), IDFS, and LATCH Score for Breastfeeding Assessment. For the Turkish validity-reliability of the IDF, the translate-back translate method was used with the content validity index (CVI) assessed.

RESULTS

The scale had CVI values between 0.90 and 1.00 with a mean CVI = 0.96. For measures 1 and 2, there were significant positive and high-level correlations between IFDS-R and IFDS-Q correlation values (r = 0.553-0.958; p = 0.001) and significant negative, low-level correlations between IFDS-R and IFDS-Q with the LATCH scale (r = 0.439-0.532; p = 0.001). According to inter-observer compatibility analyses, the kappa value was 0.94-1.00 for the first measure and 0.96-1.00 for the second measure (p = 0.001). There were negative significant correlations between IDFS-R points with gestational age and postmenstrual age (PMA) (p = 0.001), and gestational age and PMA were explanatory factors for 13.8% of IDFS-R points (F = 7.30, p = 0.001).

CONCLUSIONS

The IDFS is recommended for use as a valid and reliable tool to ease the safe and successful development of oral feeding skills in preterm infants and to plan evidence-based interventions.

IMPLICATIONS FOR PRACTICE

The IDFS appears to be a beneficial measurement device for use in assessing the state of readiness of preterm infants for oral feeding and for early determination of risks that may occur due to delayed feeding independence of infants.

Le suivi de l'extrême prématuré après le congé des soins intensifs néonatals

La survie des extrêmes prématurés (moins de 28 semaines d'âge gestationnel) s'est améliorée au fil du temps. Bon nombre s'en sortent bien et ont une bonne qualité de vie. Ils demeurent toutefois vulnérables à des problèmes de santé, y compris des difficultés neurosensorielles et neurodéveloppementales, que les médecins de première ligne, les pédiatres et les cliniques spécialisées doivent surveiller. Le présent document de principes passe en revue les conséquences médicales et neurodéveloppementales potentielles pour les extrêmes prématurés dans les deux ans suivant leur congé et fournit des stratégies de counseling, de dépistage précoce et d'intervention. Parce qu'ils sont tous liés à l'extrême prématurité, la dysplasie bronchopulmonaire ou les troubles respiratoires, les problèmes d'alimentation et de croissance, le développement neurosensoriel (vision et audition), la paralysie cérébrale et le trouble du spectre de l'autisme doivent faire rapidement l'objet d'une évaluation. Pour évaluer la croissance et le développement, il faut corriger l'âge chronologique en fonction de l'âge gestationnel jusqu'à 36 mois de vie. Par ailleurs, l'attention au bien-être émotionnel des parents et des proches fait partie intégrante des soins de qualité de l'extrême prématuré.

Follow-up care of the extremely preterm infant after discharge from the neonatal intensive care unit

The survival of babies born extremely preterm (EP, <28 weeks gestation) has improved over time, and many have good outcomes and quality of life. They remain at risk for health issues, including neurosensory and neurodevelopmental difficulties requiring monitoring by primary physicians, paediatricians, and specialty clinics. This statement reviews potential medical and neurodevelopmental consequences for EP infants in the first 2 years after discharge and provides strategies for counselling, early detection, and intervention. EP-related conditions to assess for early include bronchopulmonary dysplasia or respiratory morbidity, feeding and growth concerns, neurosensory development (vision and hearing), cerebral palsy, and autism spectrum disorder. Correction for gestational age should be used for growth and development until 36 months of age. Integral to quality care of the child born EP is attention to the emotional well-being of parents and caregivers.

Treatment of Pediatric Patients With High-Flow Nasal Cannula and Considerations for Oral Feeding: A Review of the Literature

PURPOSE

High-Flow Nasal Cannula (HFNC) has become an increasingly common means of noninvasive respiratory support in pediatrics and is being used in infants and children with respiratory distress both inside and outside of the intensive care units. Despite the widespread use of HFNC, there remains a paucity of data on optimal flow rates and its impact on morbidity, mortality, and desired outcomes. Given the scarcity of information in these critical areas, it is not surprising that guidelines for initiation of oral feeding do not exist. This review article will review HFNC mechanisms of action, its use in specific populations and settings, and finally what is known about initiation of feeding during this therapy.

CONCLUSIONS

The practice of withholding oral feeding solely, because of HFNC, is not supported in the literature at the time of this writing, but in the absence of safety data from clinical trials, clinicians should proceed with caution and consider patient-specific factors while making decisions about oral feeding. Well-controlled prospective clinical trials are needed for development of best practice clinical guidelines and attainment of optimal outcomes.

Increasing Student Confidence With Medically Complex Infants Through Simulation: A Mixed Methods Investigation

PURPOSE

The purpose of this study was to compare student knowledge and confidence, related to the assessment and management of oral feeding readiness in medically complex infants, following a written case study versus a high-fidelity human patient simulation (HPS).

METHOD

A sequential, two-phase, embedded mixed methods design was conducted. Participants were two sequential cohorts of second-year speech-language pathology graduate students enrolled in a didactic Pediatric Dysphagia course. At the end of the course, students completed the same case scenario presented as a written case study (control group; N = 28) or as an HPS (experimental group; N = 24). Pre- and post-knowledge assessment results and self-assessments of confidence conducted at three time points were compared.

RESULTS

All students made gains in knowledge, regardless of intervention (written case study or HPS). Despite different baselines, the percent change in knowledge was significant with the control group improving 33% and the experimental group improving 76% from baseline. Students in the experimental group demonstrated significantly greater gains in confidence with skills enhanced by the hands-on, immersive experience of HPS. Qualitative analysis further identified factors contributing to increased confidence with all students reporting that experience significantly contributes to their confidence in their ability to treat patients.

CONCLUSIONS

While knowledge outcomes were similar between the groups, the confidence that the experimental group gained through the hands-on experiences of HPS fosters student development as confident professionals in assessing feeding readiness and managing medically complex infants. Results support integration of simulation into the graduate curriculum to support student learning.

Eating Behaviors, Caregiver Feeding Interactions, and Dietary Patterns of Children Born Preterm: A Systematic Review and Meta-Analysis

Infants born preterm (<37 weeks of gestation) often experience feeding problems during hospitalization. Whether difficulties persist or have long-term sequelae on childhood eating is unclear. We aimed to describe the oromotor eating skills (e.g., chewing/swallowing), eating behaviors (e.g., food neophobia), food parenting practices (e.g., pressure to eat), and dietary patterns of preterm children during late infancy (6-12 mo) and early childhood (>12 mo-7 y) and to determine whether these differed from those of term-born peers. We identified 67 articles (57 unique studies) for inclusion. We used random-effects meta-analysis of proportions to examine the prevalence of oromotor eating skill and eating behavior challenges among preterm children, standard meta-analysis for comparisons with term-born peers, and the Grading of Recommendations, Assessment, Development and Evaluation approach to assess the certainty of evidence. Forty-three percent (95% CI: 24%, 62%) of infants and 25% (95% CI: 17%, 33%) of children born preterm experienced oromotor eating difficulties and 16% (95% CI: 4%, 27%) and 20% (95% CI: 11%, 28%), respectively, exhibited challenging eating behaviors. During late infancy and early childhood, oromotor eating difficulties (OR: 2.86; 95% CI: 1.71, 4.77; I2 = 67.8%) and challenging eating behaviors (OR: 1.52; 95% CI: 1.11, 2.10; I2 = 0.0%) were more common in those born preterm than in those born term: however, the certainty of evidence was very low. Owing to the low number and heterogeneity of studies, we narratively reviewed literature on food parenting and dietary patterns. Mothers of preterm infants appeared to have heightened anxiety while feeding and utilized coercive food parenting practices; their infants reportedly received less human milk, started solid foods earlier, and had poorer diet quality than term-born peers. In conclusion, meta-analyses show preterm children experience frequent oromotor eating difficulties and challenging eating behaviors throughout the early years. Given preterm birth increases risk of later obesity and diet-related chronic disease, research examining the effects of caregiver-child interactions on subsequent diet is warranted.

Cue-based feeding and short-term health outcomes of premature infants in newborn intensive care units: a non-randomized trial

BACKGROUND

Feedings based on behavioral cues is a method relying on infants' behavioral expressions of readiness to feed. The objective of this interventional study was to determine the effect of cue-based feeding on the short-term health outcomes of preterm infants.

METHODS

This quasi-experimental study utilized a historical or phase lag design. It involved 60 preterm infants admitted to an Iranian referral hospital's Level III-Newborn Intensive Care Unit (NICU) from April 2017 until January 2018. The experimental group (n = 30) received a three-step intervention of offering behavioral-cue-based oral (BCBO) feedings: Step 1 - One BCBO feeding every 12 hours for 3 days; Step 2 - Two BCBO feedings every 12 h for 3 days; and Step 3 - All feedings as BCBO feedings for 3 days. The control group received standard care feedings. Group difference data were analyzed with SPSS version 16 using descriptive and inferential statistics.

RESULTS

The infants' mean weight at time of discharge for the intervention and control groups were 1492.79 ± 21.65 g and 1395.71 ± 17.61 g (P = .003) respectively. The mean durations of achieving full oral feedings in the intervention and control groups were 17 ± 6 and 20 ± 11 days, respectively (P = .19). The mean frequencies of hypoxia were 1 ± 1.54 and 5 ± 9.31 respectively (P = .03) and of gavage feedings 725 ± 584 and 1846 ± 2097 respectively (P = .009). No apnea events were reported for the intervention group; the frequency of apnea in the control group was 1 ± 2.11 (P = .16).

CONCLUSION

The findings indicate that cue-based feeding is beneficial for preterm infants. Therefore, it is recommended that nurses employ cue-based feeding in the NICU.

A cross-sectional analysis of infant-driven and traditional feeding outcomes for neonatal intensive care unit infants

OBJECTIVE

The goal of this study was to assess the impact of infant-driven feeding (IDF) compared to traditional feeding protocols in promoting earlier successful feeding outcomes.

STUDY DESIGN

We performed a cross-sectional analysis of infants admitted to a level three neonatal intensive care unit (NICU) over a 2-year period. We compared infants fed with the traditional protocol to those under the IDF protocol.

RESULTS

Infants in the IDF group were younger at first feed (p < 0.001). There was no difference in age at nasogastric (NG) tube removal or at discharge, length of stay, or percentage breastfeeding at discharge. There were no differences in outcomes within two subgroups born at <35 and <32 weeks gestation, respectively.

CONCLUSION

The IDF program led to earlier initiation of oral feeding. However, this did not lead to earlier NG tube removal or discharge, a shorter length of stay, or increase in the rates of breastfeeding.

A Delphi survey based construction and validation of test for oropharyngeal dysphagia in Indian neonates

BACKGROUND

SLPs have a crucial need to depend on comprehensive clinical swallowing assessments to determine the presence of dysphagia in neonates. A comprehensive clinical swallowing assessment that is ethnoculturally sensitive may help to identify the presence and severity of swallowing problems in neonates.

OBJECTIVE

The study aimed to construct and validate the contents of a test for oropharyngeal dysphagia in Indian neonates (TOD-IN).

METHOD

The test for oropharyngeal dysphagia in Indian neonates (TOD-IN) was developed using the Delphi process. Five expert panelists served as participants; two rounds of electronic questionnaire-based survey was carried out to develop and validate the contents of TOD-IN.

RESULTS

Round one rendered descriptive data that was analyzed quantitatively and qualitatively. At the end of round one, panelists unequivocally agreed on the need for research to develop a validated assessment tool for dysphagia in Indian neonates. The second round dealt with establishing the face and content validity of the final version of TOD-IN. A unanimous consensus was obtained regarding the format, scoring system, and the construct of the final version of the tool.

CONCLUSION

Practicing clinicians in India are met with several challenges such as resource constraints, limited infrastructure, increasing caseload, and a lack of trained workforce. We believe that inexperienced clinicians will benefit from the structured guidance provided by TOD-IN in a restrained resource context where prioritization of patients is the key. Further studies investigating the psychometric properties of TOD-IN are in progress.

Physiological Basis of Neonatal Aerodigestive Difficulties in Chronic Lung Disease

In the United States, preterm birth rates have steadily increased since 2014. Despite the recent advances in neonatal-perinatal care, more than 40% of very low-birth-weight infants develop chronic lung disease (CLD) and almost 25% have feeding difficulties resulting in delayed achievement of full oral feeds and longer hospital stay. Establishment of full oral feeds, a major challenge for preterm infants, becomes magnified among those on respiratory support and/or with CLD. The strategies to minimize aerodigestive disorders include supporting nonnutritive sucking, developing infant-directed feeding protocols, sensory oromotor stimulation, and early introduction of oral feeds.

The Effectiveness of an Oral Sensorimotor Stimulation Protocol for the Early Achievement of Exclusive Oral Feeding in Premature Infants. A Randomized, Controlled Trial

Aims: This study is aimed to investigate the effectiveness of an oral stimulation protocol in preterm infants compared to usual care, to reduce the time for achieving safe full oral feeding.Methods: 47 preterm infants (25- 30 weeks of gestational age) were randomized into two groups. Babies of the EG (n = 24) received a 10-minute oral stimulation protocol while the CG (n = 23) received the standard care. The primary outcome were the days from the initiation of the intervention until the achievement of full oral feeding. Secondary outcomes were: days from the first day the intervention started until achieving a first oral intake of 30% in the first 5 minutes, days from the first day the intervention started until achieving a first oral intake of 100%, and days of hospitalization. A parametric survival model with Gaussian distribution was used.Results: The EG achieved full oral feeding 8.3 days before the CG (p = 0.013). EG also achieved the first oral intake of 30% in the first five minutes, 6.03 days before (p = 0.019) and of 100%, 5.88 days before (p = 0.040). EG also spent 6.9 days less hospitalized than CG (p = 0.028).Conclusion: Oral stimulation in preterm infants significantly shortens the time to achieve full oral feeding and reduces the length of hospitalization.

Individualised developmental care for babies and parents in the NICU: Evidence-based best practice guideline recommendations

Advances in neonatal care have improved survival of premature and critically ill infants; and while rates of some long-term neurodevelopmental problems in survivors have improved, such as cerebral palsy, there are others such as learning and behavioural difficulties that have not. The goal of improving long term neurodevelopmental morbidity has led to an increased focus on improving developmental care not only in neonatal long term follow- up clinics but within the NICU itself to capture the period of earliest brain neuroplasticity. The application of a systematic approach to improve practice is considered the most effective strategy for implementing neuroprotective developmentally supportive care. The content of this paper incorporates evidence-based systematic reviews to guide clinicians in the application of developmentally supportive interventions.

Nutritive sucking abnormalities and brain microstructural abnormalities in infants with established brain injury: a pilot study

OBJECTIVE

To determine the relationship between nutritive sucking and microstructural integrity of sensorimotor tracts in newborns with brain injury.

STUDY DESIGN

Diffusion imaging was performed in ten newborns with brain injury. Nutritive sucking was assessed using Nfant®. The motor, sensory, and corpus callosum tracts were reconstructed via tractography. Fractional anisotropy, radial, axial, and mean diffusivity were estimated for these tracts. Multiple regression models were developed to test the association between sucking features and diffusion parameters.

RESULTS

Low-sucking smoothness correlated with low-fractional anisotropy of motor tracts (p = 0.0096). High-sucking irregularity correlated with high-mean diffusivity of motor (p = 0.030) and corpus callosum tracts (p = 0.032). For sensory tracts, high-sucking irregularity (p = 0.018) and low-smoothness variability (p = 0.002) correlated with high-mean diffusivity.

INTERPRETATION

We show a correlation between neuroimaging-demonstrated microstructural brain abnormalities and variations in sucking patterns of newborns. The consistency of this relationship should be shown on larger cohorts.

The impact of neonatal unit policies on breast milk feeding at discharge of moderate preterm infants: The EPIPAGE-2 cohort study

Facilitating factors and barriers to breast milk feeding (BMF) for preterm infants have been mainly studied in very preterm populations, but little is known about moderate preterm infants. We aimed to analyze hospital unit characteristics and BMF policies associated with BMF at discharge for infants born at 32 to 34 weeks' gestation. EPIPAGE-2, a French national cohort of preterm births, included 883 infants born at 32 to 34 weeks' gestation. We investigated kangaroo care in the first 24 hr, early involvement of parents in feeding support, volume of the unit, BMF information given to mothers hospitalized for threatened preterm delivery, protocols for BMF, presence of a professional trained in human lactation, unit training in neurodevelopmental care, and regional BMF initiation rates in the general population. Multilevel logistic regression analysis was used to investigate associations between unit policies and BMF at discharge, adjusted for individual characteristics and estimating odds ratios (ORs) and 95% confidence intervals (CIs). Overall, 59% (490/828) of infants received BMF at discharge (27% to 87% between units). Rates of BMF at discharge were higher with kangaroo care (adjusted OR 2.03 [95% CI 1.01, 4.10]), early involvement of parents in feeding support (1.94 [1.23, 3.04]), unit training in a neurodevelopmental care programme (2.57 [1.18, 5.60]), and in regions with a high level of BMF initiation in the general population (1.85 [1.05, 3.28]). Creating synergies by interventions at the unit and population level may reduce the variability in BMF rates at discharge for moderate preterm infants.

A comparison of the nutritive sucking performance of full term and preterm neonates at hospital discharge: A prospective study

BACKGROUND

Studies show that 40% to 70% of premature infants exhibit both immature and atypical feeding ability. To establish thresholds of performance and develop efficacious treatments for initiating and advancing oral feedings, we must first identify the nutritive sucking performance measures impacted by preterm birth.

AIMS

To compare objective measures of neonatal nutritive sucking between full term and preterm infants at hospital discharge.

STUDY DESIGN AND METHODS

This was a prospective observational study including full term (FT; N = 32) and preterm (PT; N = 44) infants. Nutritive sucking performance at discharge was assessed. The outcome measures of interest were means and coefficients of variability of nutritive sucking peak amplitude, frequency, duration, and smoothness, and feeding-related length of stay.

RESULTS

There was a significant difference in sucking performance between groups; FT infants demonstrated significantly lower mean suck frequency, with longer suck duration and greater suck smoothness as compared to PT. PT infants had significantly less variability in suck amplitude and frequency as compared to FT, while FT infants had significantly less variability in suck smoothness as compared to PT. Post hoc regression analyses found suck frequency alone accounted for 28% of the variance in feeding length of stay for PT; suck smoothness alone accounted for 34% of the variance in feeding length of stay for FT.

CONCLUSIONS

Suck frequency may be an important intervention target for PT infants having difficulty transitioning to oral feeding. Suck smoothness may be a sensitive marker for identifying infants at high risk for feeding challenges.

Optimal Timing to Utilize Olfactory Stimulation with Maternal Breast Milk to Improve Oral Feeding Skills in the Premature Newborn

Background: Olfactory maturation is essential for successful oral feeding. Previous studies have suggested that olfactory stimulation with maternal breast milk may expedite oral feeding skills in the premature infant; however, the optimal developmental window to utilize this intervention and sex-specific responses to stimuli are largely unknown. Objectives: To determine individual responses to olfactory stimulation with mother's own milk (MOM) on feeding outcomes in premature newborns. Materials and Methods: Infants born between 28 0/7 and 33 6/7 weeks' gestation (n = 36) were randomized to receive either MOM or water (sham) stimulus during the learning process of oral feeding. Clinical and feeding outcomes were recorded. Statistical analyses examined the effect of stimulation with MOM on feeding outcomes stratified for age and sex. Results: Overall, there was no significant difference between sham infants compared with MOM infants in mean postmenstrual age of full oral feeds (sham: 35 5/7 versus MOM 36 0/7; p = 0.37). However, when stratified by gestational age (GA), infants born <31 weeks' gestation who received MOM stimulation learned to feed sooner than controls (p = 0.06), whereas infants born ≥31 weeks' gestation learned to feed later than controls (p = 0.20) with a significant interaction (p = 0.02) between the stimulus (MOM versus sham) and dichotomized GA (<31 versus ≥31 weeks). There were no sex differences in response to olfactory stimulus. Conclusions: Infants born <31 weeks' GA who received MOM stimulation learned to feed sooner than control infants and the impact of MOM is significantly different between infants born before or after 31 weeks GA. These data suggest there may be an optimal time in development to utilize maternal breast milk to expedite oral feeding maturation in the premature newborn.

Patterned frequency-modulated oral stimulation in preterm infants: A multicenter randomized controlled trial

Objective

To evaluate the effect of patterned, frequency-modulated oro-somatosensory stimulation on time to full oral feeds in preterm infants born 26–30 weeks gestation.

Study design

This is a multicenter randomized controlled trial. The experimental group (n = 109) received patterned, frequency-modulated oral stimulation via the NTrainer system through a pulsatile pacifier and the control group (n = 101) received a non-pulsatile pacifier. Intent-to-treat analysis (n = 210) was performed to compare the experimental and control groups and the outcomes were analyzed using generalized estimating equations. Time-to-event analyses for time to reach full oral feeds and length of hospital stay were conducted using Cox proportional hazards models.

Results

The experimental group had reduction in time to full oral feeds compared to the control group (-4.1 days, HR 1.37 (1.03, 1.82) p = 0.03). In the 29–30 weeks subgroup, infants in the experimental group had a significant reduction in time to discharge (-10 days, HR 1.87 (1.23, 2.84) p < 0.01). This difference was not observed in the 26–28 weeks subgroup. There was no difference in growth, mortality or morbidities between the two groups.

Conclusions

Patterned, frequency-modulated oro-somatosensory stimulation improves feeding development in premature infants and reduces their length of hospitalization.

Full oral feeding is possible before discharge even in extremely preterm infants

AIM

This study described the steps needed to achieve full oral feeding before discharge in a group of very and extremely preterm (EPT) infants. We analysed the effects of oral feeding skills on discharge timing and on weight gain during their neonatal intensive care unit (NICU) stay.

METHODS

A prospective cross-sectional observational study of 100 infants who were <32 weeks of gestation (GA) was conducted at the Division of Neonatology, Graz, Austria, from March 2014 to February 2015. Patients were stratified into two groups: those who were <28 weeks at birth and those who were 28 weeks and over. Velocity of oral feeding skills attainment and weight gain were analysed.

RESULTS

All infants successfully acquired oral feeding skills during hospitalisation. The median GA at which full oral feeding skills were reached was 37 + 1 weeks in EPT and 34 + 5 weeks in very preterm infants. More immature neonates showed worse feeding performances and lower weight increments during oral feeding steps.

CONCLUSION

Our study confirmed the role of GA in the development of oral feeding skills in the most premature babies. It also raises the question of whether expected daily weight gain should be targeted according to GA.

Unit policies and breast milk feeding at discharge of very preterm infants: The EPIPAGE-2 cohort study

BACKGROUND

Facilitating factors and barriers to breast milk feeding (BMF) very preterm (VP) infants have been widely studied at the individual level. We aimed to describe and analyse factors associated with BMF at discharge for VP infants, with a special focus on unit policies aiming to support BMF.

METHODS

We described BMF at discharge in 3108 VP infants enrolled in EPIPAGE-2, a French national cohort. Variables of interest were kangaroo care during the 1st week of life (KC); unit's policies supporting BMF initiation (BMF information systematically given to mothers hospitalised for threatened preterm delivery and breast milk expression proposed within 6 hours after birth) and BMF maintenance (availability of protocols for BMF and a special room for mothers to pump milk); the presence in units of a professional trained in human lactation and regional BMF initiation rates in the general population. Associations were investigated by multilevel logistic regression analysis, with adjustment on individual factors.

RESULTS

In total, 47.2% of VP infants received BMF at discharge (range among units 21.1%-84.0%). Unit policies partly explained this variation, regardless of individual factors. BMF at discharge was associated with KC (adjusted odds ratio (aOR) 2.26 (95% confidence interval (CI) 1.40, 3.65)), with policies supporting BMF initiation (aOR 2.19 (95% CI 1.27, 3.77)) and maintenance (aOR 2.03 (95% CI 1.17, 3.55)), but not with BMF initiation rates in the general population.

CONCLUSION

Adopting policies of higher performing units could be an effective strategy for increasing BMF rates at discharge among VP infants.

Quantifying the Impact of Common Feeding Interventions on Nutritive Sucking Performance Using a Commercially Available Smart Bottle

An estimated 25% to 40% of infants experience difficulties with learning to breast- or bottle-feed. Yet, guidelines and evidence-based support for common feeding practices are limited. The objective of this case report was to quantify the impact of feeding interventions on nutritive sucking performance after discharge in an outpatient setting. This observational case series involved 2 infants. To determine the impact of cumulative interventions, pre- and postintervention effect sizes were calculated. Sucking performance metrics of interest included nipple movement peak sucking amplitude, duration, frequency, and smoothness. Interventions included positional changes and changes in nipple flow rate, among others. For both infants, cumulative interventions had the greatest impact on suck frequency; postintervention, infants were able to increase their rate of nutritive sucking per burst. Other aspects of sucking performance were differentially impacted for each baby. Researchers agree that neonatal and infant feeding has been understudied and that the evidence for common interventions needs to be strengthened. We have demonstrated the implementation of readily available technology that can be used to quantify the direct impact of any intervention on actual sucking performance. In doing so, we can individualize care to support skill development and improve outcomes for infants at risk for ongoing feeding challenges.

A Decision Tree for Donor Human Milk: An Example Tool to Protect, Promote, and Support Breastfeeding

Despite decades of breastfeeding promotion, exclusive breastfeeding rates for the first 6 months of life remain low: around 40% globally. Infants that are admitted to a neonatal ward are even less likely to be exclusively breastfed. Lactogenesis is frequently delayed in mothers that deliver early, with the added burden of separation of the unstable newborn and mother. For such vulnerable infants, donor human milk is recommended by the World Health Organization, UNICEF, and professional organizations as the next best alternative when mother's own milk is unavailable and can serve as a bridge to full feeding with mother's own milk. Hospital support of optimal breastfeeding practices is essential with thoughtful integration of donor human milk policies for those infants that need it most. We propose a decision tree for neonatal wards that are considering the use of donor human milk to ensure donor human milk is used to replace formula, not to replace mothers' own milk. By first evaluating barriers to full feeding with mother's own milk, healthcare workers are encouraged to systematically consider the appropriateness of donor human milk. This tool also seeks to prevent overuse of donor human milk, which has the potential to undermine successful lactation development. In settings where donor human milk supplies are limited, prioritization of infants by medical status is also needed. Readily available and easy-to-use tools are needed to support healthcare staff and mothers in order to improve lactation development and neonatal nutrition.

Usefulness of the Infant Driven Scale in the early identification of preterm infants at risk for delayed oral feeding independency

BACKGROUND

Very preterm infants frequently experience difficulties in achieving feeding independency. The availability of feeding assessment instruments has been recommended to evaluate an infant's readiness for oral feeding and enable preterm infants' caregivers to document each infant's feeding readiness and advancements.

AIMS

To investigate the implementation of the Infant Driven Scale in neonatal intensive care units and to identify a cut off value associated with delayed feeding independency.

STUDY DESIGN

Prospective, observational, single-centre study.

SUBJECTS

A total of 47 infants born at a gestational age≤32weeks, consecutively admitted to a tertiary neonatal unit between July 2015 and March 2016.

OUTCOMES MEASURES

The infant's feeding readiness and the postmenstrual age at achievement of feeding independency.

RESULTS

Mean postmenstrual age at feeding independency was 35.6±1.34weeks. A linear regression analysis showed that a score≤8 at 32weeks of postmenstrual age was associated with a delay of 1.8weeks in achieving feeding independency.

CONCLUSION

The Infant Driven Scale appears to be a useful additional instrument for the assessment of preterm infants' oral feeding readiness and the early identification of the infants at risk for delayed feeding independency.

Verification of Reliability and Validity of the Feeding and Swallowing Scale for Premature Infants (FSSPI)

Objective

To propose a new scale, the Feeding and Swallowing Scale for Premature Infants (FSSPI), based on videofluoroscopic swallowing study (VFSS) findings and to verify the reliability and validity of the FSSPI.

Methods

One hundred thirty preterm infants who had undergone VFSS were enrolled in this retrospective study. The FSSPI was developed by referring to the Baby Regulated Organization of Subsystems and Sucking approach. The FSSPI score for each VFSS video was evaluated by a physiatrist as well as by three experienced speech-language pathologists. To verify the reliability of the FSSPI, the inter-evaluator and intra-evaluator associations for the FSSPI scores were analyzed. To verify the validity of the FSSPI, the association between FSSPI scores and clinical characteristics including prognosis-related factors was analyzed.

Results

The mean gestational age was 27.3±2.8 weeks. The FSSPI showed a high degree of both intra-rater reliability and inter-rater reliability. Also, there was a significant negative correlation between the FSSPI score and corrected age (CA) at the time of performing VFSS. Further, a significant positive correlation was observed between the FSSPI score and CA at the time of achieving full oral feeding. A significant negative correlation was observed between the FSSPI score and weight gain, between the 1st and 2nd month after birth, and between the 2nd and 3rd month after birth, respectively.

Conclusion

In this study, we proposed a new clinical scale using VFSS to reflect the development of feeding and swallowing skills in preterm infants. Further, we verified the reliability and validity of the scale.

Quantifying Neonatal Sucking Performance: Promise of New Methods

Neonatal feeding has been traditionally understudied so guidelines and evidence-based support for common feeding practices are limited. A major contributing factor to the paucity of evidence-based practice in this area has been the lack of simple-to-use, low-cost tools for monitoring sucking performance. We describe new methods for quantifying neonatal sucking performance that hold significant clinical and research promise. We present early results from an ongoing study investigating neonatal sucking as a marker of risk for adverse neurodevelopmental outcomes. We include quantitative measures of sucking performance to better understand how movement variability evolves during skill acquisition. Results showed the coefficient of variation of suck duration was significantly different between preterm neonates at high risk for developmental concerns (HRPT) and preterm neonates at low risk for developmental concerns (LRPT). For HRPT, results indicated the coefficient of variation of suck smoothness increased from initial feeding to discharge and remained significantly greater than healthy full-term newborns (FT) at discharge. There was no significant difference in our measures between FT and LRPT at discharge. Our findings highlight the need to include neonatal sucking assessment as part of routine clinical care in order to capture the relative risk of adverse neurodevelopmental outcomes at discharge.

Preliminary psychometric performance of the Neonatal Feeding Assessment Scale

Objective

The objective was to determine the preliminary psychometric performance of a new clinical feeding scale to diagnose oropharyngeal dysphagia (OPD) in neonates.

Methods

Twenty neonates with a median gestational age of 35 weeks were evaluated using the Neonatal Feeding Assessment Scale (NFAS) and modified barium swallow studies (MBSS). The results were compared.

Results

Nine of the 20 participants presented with OPD on the NFAS. Comparison of the scale’s results with instrumental MBSS indicated that all participants without OPD were correctly excluded (100% sensitivity). The specificity was 78.6%, indicating that three participants were falsely identified with OPD on the scale. Inter-rater reliability was determined on 50% (n = 10) of the sample. Substantial agreement (80%) was obtained between two raters in five of the six sections of the scale and on the diagnostic outcome.

Conclusion

The preliminary performance of the scale appears to be promising. A further validation study will take place.

Does parental involvement affect the development of feeding skills in preterm infants? A prospective study

BACKGROUND

Feeding difficulties frequently occur in preterm infants, thus contributing to delayed growth and hospital discharge.

AIMS

To evaluate the effect of Kangaroo mother care implementation and parental involvement in infants' feeding on the timing of achievement of full oral feeding in preterm infants.

STUDY DESIGN

Prospective, observational, single-centre study.

SUBJECTS

A total of 81 infants born at a gestational age ≤32weeks, consecutively admitted to a tertiary neonatal unit between June 2014 and May 2015.

OUTCOME MEASURES

The timing of the achievement of full oral feeding of preterm infants.

RESULTS

Full oral feeding was achieved at a mean postmenstrual age of 35.5±2.1weeks. A multiple linear regression analysis showed that a low birth weight, the occurrence of bronchopulmonary dysplasia, and the need for gastrointestinal surgical procedures were associated with a higher postmenstrual age at achievement of full oral feedings. By contrast, the earlier that parents fed their infants and the earlier that Kangaroo mother care was started, the lower the postmenstrual age at the achievement of full oral feeding.

CONCLUSIONS

These findings indicate that an early start of Kangaroo mother care and early parental involvement in infants' feeding positively affect the achievement of independent oral feeding.

Development of a clinical feeding assessment scale for very young infants in South Africa

Background

There is a need for validated neonatal feeding assessment instruments in South Africa. A locally developed instrument may contribute to standardised evaluation procedures of high-risk neonates and address needs in resource constrained developing settings.

Objective

The aim of the study was to develop and validate the content of a clinical feeding assessment scale to diagnose oropharyngeal dysphagia (OPD) in neonates.

Method

The Neonatal Feeding Assessment Scale (NFAS) was developed using the Delphi method. Five international and South African speech-language therapists (SLTs) formed the expert panel, participating in two rounds of electronic questionnaires to develop and validate the content of the NFAS.

Results

All participants agreed on the need for the development of a valid clinical feeding assessment instrument to use with the neonatal population. The initial NFAS consisted of 240 items across 8 sections, and after the Delphi process was implemented, the final format was reduced to 211 items across 6 sections. The final format of the NFAS is scored using a binary scoring system guiding the clinician to diagnose the presence or absence of OPD. All members agreed on the format, the scoring system and the feeding constructs addressed in the revised final format of the NFAS.

Conclusion

The Delphi method and the diverse clinical and research experience of participants could be integrated to develop the NFAS which may be used in clinical practice in South Africa or similar developing contexts. Because of demographically different work settings marked by developed versus developing contexts, participants did not have the same expectations of a clinical dysphagia assessment. The international participants contributed to evidence-based content development. Local participants considered the contextual challenges of South African SLTs entering the field with basic competencies in neonatal dysphagia management, thereby justifying a comprehensive clinical instrument. The NFAS is aimed at clinicians working in Neonatal Intensive Care Units where they manage large caseloads of high-risk neonates. Further validation of the NFAS is recommended to determine its criterion validity in comparison with a widely accepted standard such as the modified barium swallow study.

Translating Neurodevelopmental Care Policies Into Practice: The Experience of Neonatal ICUs in France-The EPIPAGE-2 Cohort Study

OBJECTIVES

To describe the implementation of neurodevelopmental care for newborn preterm infants in neonatal ICUs in France in 2011, analyze changes since 2004, and investigate factors associated with practice.

DESIGN

Prospective national cohort study of all births before 32 weeks of gestation.

SETTING

Twenty-five French regions.

PARTICIPANTS

All neonatal ICUs (n = 66); neonates surviving at discharge (n = 3,005).

INTERVENTIONS

None.

MEASUREMENTS AND MAIN RESULTS

Neurodevelopmental care policies and practices were assessed by structured questionnaires. Proportions of neonates initiating kangaroo care during the first week of life and those whose mothers expressed breast milk were measured as neurodevelopmental care practices. Multilevel logistic regression analyses were used to investigate relationships between kangaroo care or breast-feeding practices and unit policies, taking into account potential confounders. Free visiting policies, bed availability for parents, and kangaroo care encouragement significantly improved between 2004 and 2011 but with large variabilities between units. Kangaroo care initiation varied from 39% for neonates in the most restrictive units to 68% in less restrictive ones (p < 0.001). Individual factors associated with kangaroo care initiation were gestational age (odds ratio, 5.79; 95% CI, 4.49-7.48 for babies born at 27-31 wk compared with babies born at 23-26 wk) and, to a lesser extent, single pregnancy, birthweight above the 10th centile, and mother's employment before pregnancy. At unit level, policies and training in neurodevelopmental care significantly influenced kangaroo care initiation (odds ratio, 3.5; 95% CI, 1.8-7.0 for Newborn Individualized Developmental Care and Assessment Program implementation compared with no training). Breast milk expression by mothers was greater in units with full-time availability professionals trained for breast-feeding support (60% vs 73%; p < 0.0001).

CONCLUSIONS

Dissemination of neurodevelopmental practices occurred between 2004 and 2011, but large variabilities between units persist. Practices increased in units with supportive policies. Specific neurodevelopmental care training with multifaceted interventions strengthened the implementation of policies.

Fiberoptic Endoscopic Evaluation of Swallowing: A Multidisciplinary Alternative for Assessment of Infants With Dysphagia in the Neonatal Intensive Care Unit

BACKGROUND

The standard procedure to assess an infant in the neonatal intensive care unit (NICU) who is suspected of aspirating on oral feedings is a videofluoroscopic swallowing study (VFSS). The VFSS has been used for more than 30 years to assess dysphagia and is considered the gold standard. However, there are challenges to the VFSS, including radiation exposure, transport to radiology, usage of barium, limited positioning options, and cost. An alternative approach is fiberoptic endoscopic evaluation of swallowing (FEES), which uses a flexible endoscope passed transnasally into the pharynx to assess anatomy, movement/sensation of structures, swallow function, and response to therapeutic interventions. Fiberoptic endoscopic evaluation of swallowing has been established as a valid tool for evaluating dysphagia and utilized as an alternative or supplement to the VFSS in both adults and children.

PURPOSE

This article provides an overview of the current challenges in the NICU with assessing aspiration and introduces a multidisciplinary FEES program for bottle and breastfeeding.

METHODS/SEARCH STRATEGY

A review of the literature of dysphagia, VFSS, and FEES in the adult, pediatric, infant, and neonatal populations was performed. Clinical competency standards were researched and then implemented through an internal process of validation. Finally, a best practice protocol was designed as it relates to FEES in the NICU.

FINDINGS/RESULTS

Fiberoptic endoscopic evaluation of swallowing is a safe alternative to the VFSS. It can be utilized at the infant's bedside in a NICU for the diagnosis and treatment of swallowing disorders by allowing the clinician the ability to replicate a more accurate feeding experience, therefore, determining a safe feeding plan.

IMPLICATIONS FOR PRACTICE

Competency and training are essential to establishing a multidisciplinary FEES program in the NICU.

IMPLICATIONS FOR RESEARCH

Further research is needed to compare the efficacy and validity of FEES versus VFSS for infants in the NICU. Furthermore, evaluating the efficacy of FEES during breastfeeding is warranted.

Eating in "SINC": Safe Individualized Nipple-Feeding Competence, a Quality Improvement Project to Explore Infant-Driven Oral Feeding for Very Premature Infants Requiring Noninvasive Respiratory Support

Oral feeding is a developmental task for all premature infants. often, independent nipple feeding is the last barrier to discharge home from the NICU. A relationship exists between consistent, infant-driven feeding management practices and improved feeding performance. Conversely, a random approach to feeding may contribute to poor short-term and long-term clinical outcomes. We report a quality improvement project that was undertaken across five NICUs in an urban setting. our aim was to safely initiate and advance nipple feeding for very preterm neonates (born at <32 weeks gestation) who had a respiratory morbidity requiring nasal continuous positive airway pressure therapy. A novel algorithm entitled "eating in SINC: Safe individualized nipple-Feeding Competence" was developed. Safe individualized nipple-feeding competence involves the baby, the parents, and the health care team by using infant-driven strategies, common language, and developmentally appropriate goals while supporting fragile neonates to be skilled feeders.

Feeding in the NICU: A Perspective from a Craniosacral Therapist

Completing full feedings is a requirement for discharge for babies in the NICU. interaction between the nerves and the muscles of the jaw, tongue, and the soft palate is required for functional sucking and swallowing. Jaw misalignment, compressed nerves, and misshapen heads can interfere with these interactions and create feeding difficulties. craniosacral therapy (CST) is a noninvasive manual therapy that is perfect for the fragile population in the NICU. CST can be used as a treatment modality to release fascial restrictions that are affecting the structures involved in feeding, thereby improving feeding outcomes.

Dietary transition difficulties in preterm infants: critical literature review

OBJECTIVE

To analyze the scientific literature on dietary changes in preterm children during the first years of life.

DATA SOURCE

The PubMed database was used for article selection. The texts were analyzed according to their objectives, research design, and research group characteristics. The following were selected to comprise the criteria: (1) publications in the period from 1996 to 2014; (2) participation of infants and children from birth to 10 years of age; (3) development of oral motor skills necessary for feeding; (4) development of the feeding process; and (5) feeding difficulties during childhood.

SUMMARY OF THE FINDINGS

There were 282 studies identified, of which 17 were used in the review, and five more articles were identified through the reference list of selected articles, totaling 22 references.

CONCLUSION

Very low birth weight preterm newborns are more likely to have feeding problems in early postnatal stages and during childhood when compared with full-term infants. Monitoring the feeding of these infants after hospital discharge is strictly recommended in an early intervention program aiming at better development of feeding skills.

Supporting Oral Feeding Skills Through Bottle Selection

Infants who have feeding difficulties often struggle with coordinating sucking, swallowing, and breathing, and have difficulty eating sufficient quantities for adequate growth. Speech-language pathologists (SLPs) need advanced expertise across a number of areas (e.g., development, medical, swallowing) to work effectively with these young infants, and they use a variety of strategies when treating this population. Therapists working with infants who have feeding difficulties use bottles as a primary therapy tool; how the infant tolerates the flow rate from the bottle/nipple is a major consideration. Caregivers must understand the influence of bottle/nipple flow rates on eating skills, so they can support the emerging oral skill development for these fragile infants, and help parents decide what bottle system to use in their home. Both infant and equipment factors influence bottle/nipple flow rates. This article discusses the influencing factors that need to be considered when determining the optimal flow rate for an individual infant.

Influência do estado comportamental nos padrões de sucção de recém-nascidos pré-termo

Objetivo Verificar a influência do estado comportamental na sucção não nutritiva, na sucção nutritiva e na performance alimentar de recém-nascidos pré-termo, no momento da liberação da via oral. Métodos Participaram 32 recém-nascidos pré-termo, clinicamente estáveis, internados em uma unidade de terapia intensiva neonatal. Foram realizadas, por um fonoaudiólogo, as avaliações do estado comportamental, padrão postural, reflexos orais, características dos órgãos fonoarticulatórios, sucção não nutritiva e nutritiva, número de suções por bloco de sucção, taxa de transferência e desempenho alimentar, após a liberação médica para início da alimentação por via oral. Resultados Não foi possível verificar associação do estado comportamental com a sucção não nutritiva. Na sucção nutritiva, verificou-se influência do estado comportamental sobre o número de sucções nos três primeiros blocos, ou seja, o estado de alerta, ao iniciar a mamada, possibilitou aos recém-nascidos apresentarem maior número de sucções, quando comparados aos recém-nascidos em estado de sono. Isto se refletiu na performance alimentar, por meio da maior taxa de transferência e melhor desempenho, embora não tenha sido observada significância estatística quanto a esses aspectos. Conclusão Os achados mostram que o estado comportamental não influenciou os aspectos de sucção não nutritiva, considerados, entretanto, na sucção nutritiva. O estado de alerta apresentou associação com maior número de sucções por bloco, em relação ao estado de sono.

Setting the stage for successful oral feeding: the impact of implementing the SOFFI feeding program with medically fragile NICU infants

To evaluate the impact of implementing the Supporting Oral Feeding in Fragile Infants (SOFFI) program in a tertiary-level neonatal intensive care unit (NICU) on the oral feeding, growth, and length of stay outcomes of a heterogeneous population of medically fragile infants at discharge and feeding and growth outcomes postdischarge at 3 to 5 months postterm. Data related to feeding, growth, and length of stay from a convenience sample of 81 infants recruited pre-SOFFI training were compared with data for 75 infants recruited post-SOFFI training of the NICU staff. Subjects were not excluded on the basis of level of illness or medical diagnoses. To establish comparability of subject groups, infants were assigned scores using the Neonatal Medical Index. At 3 to 5 months postterm, semistructured parent phone interviews related to feeding and growth at home were conducted (n = 128). Post-SOFFI infants born at less than 37 weeks' gestation achieved full oral feedings in significantly fewer days than pre-SOFFI infants (P = .01). Time to achieve full oral feedings was not significantly different in post-SOFFI infants born at 37 or more weeks' gestation. Growth and length of stay were not significantly different at discharge. At follow-up, parents of post-SOFFI infants reported significantly fewer feeding problems overall (P = .01), less arching (P = .003), less vomiting (P = .006), and fewer infants seeing feeding specialists (P = .03). Results of the study support that NICU implementation of the SOFFI feeding program positively influences feeding outcomes before and following discharge.

Cue-based feeding in the NICU: using the infant's communication as a guide

Although studies have shown cue-based feeding can lead to earlier achievement of full oral feeding, the successful implementation of cue-based feeding has been constrained by the volume-driven culture, which has existed for many years in the NIC U. This culture was built on the notion that a "better" nurse is one who could "get more in," and infants who are "poor feeders" are ones who "can't take enough." The infant who feeds faster is often viewed as more skilled in this task-oriented approach. The feeding relationship and the infant's communication about the experience of feeding may not be nurtured. This article will explain the central role of the preterm infant's communication in successful cue-based feeding. When the infant is perceived as having meaningful behavior (i.e., communicative intent), the focus changes from a volume-driven to a co-regulated approach, through which the infant guides the caregiver. This is cue-based feeding.
