Oral stimulation for promoting oral feeding in preterm infants

Reducing the Duration to Reach Full Enteral and Oral Feeding Volumes for Very Preterm and Extremely Preterm Infants: A Quality Improvement Project

BACKGROUND

Enteral and oral feeding are crucial for infants with a gestational age <32 weeks during hospitalization, with potential for improved outcomes through optimized feeding practices.

PURPOSE

To shorten the time to achieve full enteral and oral feeding volumes in infants with a gestational age <32 weeks.

METHODS

This pre-post-intervention study focused on patients with a gestational age <32 weeks in Shenzhen City, 44 bed NICU. Quality improvement interventions included workflow enhancements, breastfeeding education, and oral motor strategies. Analysis of feeding times and hospital stays was conducted using SPSS software, alongside a provider survey to project feasibility.

RESULTS

Statistical significant improvements were seen in full enteral feeding time for infants under 28 weeks gestation and full oral feeding time for those between 28 and 30 weeks. Length of stay did not show significant differences between period. Providers unanimously found the intervention feasible and acceptable.

IMPLICATIONS

Quality improvement interventions can expedite achievement of full feeding volumes in preterm infants, with potential for enhanced feeding outcomes.

Effectiveness of a Novel Feeding Algorithm for Oral Feeding Transition of Infants Born Prematurely

BACKGROUND

Feeding skill acquisition is commonly a limiting factor determining when an infant born prematurely can be discharged.

PURPOSE

This study aimed to determine if the addition of a novel feeding progression algorithm (combination of objective data from a suck measurement device and slow flow/low variability nipples) to current neonatal intensive care unit (NICU) standards could decrease feeding-related length of stay (primary outcome). We hypothesized that by timing the initiation of oral feedings to coincide with adequate sensory-motor skill development, feeding-related length of stay may be decreased.

METHODS

This was a prospective intervention study, with a historical control cohort, of infants born less than 30 weeks' gestational age without comorbidities affecting feeding skill acquisition at a Regional Level III-S NICU at a women and infant's hospital in Louisiana. A novel feeding progression algorithm utilized objective assessment of sucking to determine progression in nipple flow rates with slow flow/low variability nipples (flow rates from 0 to 9 mL/min) for infants receiving intervention (n = 18). Thirty-six controls who did not receive the feeding progression algorithm were identified via electronic medical record retrospective chart review.

RESULTS

Eighteen completed the study. Compared to the control group, infants receiving feeding interventions had delayed sequencing initiation, extended time between initially off positive pressure ventilation and initiation of sequencing, and decreased feeding-related length of stay, with similar total length of stay.

IMPLICATIONS FOR PRACTICE AND RESEARCH

This study adds to existing research supporting the effectiveness of novel feeding progression algorithms and interventions to support the health and outcomes of infants born prematurely. Future research should focus on implementation studies for feeding progression algorithm integration into standard NICU care.

A Ducted, Biomimetic Nipple Improves Aspects of Infant Feeding Physiology and Performance in an Animal Model

Breastfeeding is widely regarded as the optimal form of feeding infants, as it provides both nutritional and physiological benefits. For example, breastfed infants generate greater intraoral suction and have higher amplitude muscle activities compared to bottle-fed infants, with downstream implications for motor function, development, and health. One mechanism that might explain these physiological differences is the structure of the nipple an infant is feeding on. Breasts in most mammals are ducted soft-tissue structures that require suction to be generated for milk to be released, whereas bottle nipples are hollow and allow milk to be acquired by compression of the nipple. We used a validated animal model (pigs) to test how being raised on a novel ducted nipple impacted feeding physiology and performance compared to infants raised on a standard (cisternic) nipple. At the end of infancy, we fed both groups with both nipple types and used high-speed videofluoroscopy synchronized with intraoral pressure measurements to evaluate feeding function. Nipple type did not have a profound impact on sucking or swallowing rates. However, when feeding on a ducted nipple, infant pigs raised on a ducted nipple generated more suction, consumed milk at a faster rate, swallowed larger boluses of milk, and had decreased likelihood of penetration and aspiration than those raised on a cisternic nipple. These data replicate those found when comparing breast- and bottle-fed infants, suggesting that a ducted, biomimetic nipple may provide bottle-fed infants with the physiologic benefits of breastfeeding.

Introduction of oral feeding in premature infants on high flow nasal cannula in a level IV neonatal intensive care unit: a quality improvement initiative

BACKGROUND

Failure to reach full oral feeding remains a significant barrier for premature infants to discharge home. Postmenstrual age (PMA) at first oral feeding is significantly associated with the length of hospital stay (LOS).

METHODS

Single-center QI to introduce oral feeding to infants on high-flow nasal cannula (HFNC) by reducing the flow to 2 L during feeds.

GLOBAL AIM

To reduce PMA at first oral feeding and reduce the LOS.

SMART AIM

To introduce oral feeds in 40% of infants who are on ≤4 L HFNC by the end of 12 months.

RESULTS

Over 12 months, SMART aim reached with 100% enrollment. PMA at first oral feeding decreased from a median of 42.4w ((IQR) (40,46.6) to 37.8w (35.8,43.2), PMA at discharge decreased from 47w (44.6,50.7) to 42.6w (41.3,48.8).

CONCLUSION

Allowing oral feeding in infants while on HFNC is feasible. This approach can significantly reduce PMA at first and full oral feeding.

The effectiveness of oral motor interventions on the weight gain, independent oral feeding, and length of hospital stay in hospitalized preterm infants: A systematic review and meta-analysis

Background and Aims

Oral feeding for preterm infants has been a challenging issue globally. In an effort to enhance the effectiveness of oral feeding in preterm infants, oral motor intervention (OMI) was developed. Present systematic review and meta-analysis study aims to examine the impact of various OMI techniques on key outcomes, including body weight at the time of discharge, the duration required to achieve independent oral feeding, and the length of hospital stay for preterm infants.

Methods

A systematic search of the literature was performed across various databases such as PubMed, Scopus, and Web of Science and Google Scholar up to September 28, 2023. Quality assessment was conducted using the Joanna Briggs Institute (JBI) checklist. The overall effect measure was calculated using a random-effects model and was presented as the standard difference of the mean (SDM), accompanied by the standard error and a 95% confidence interval (CI). We used I 2 statistic for investigating the heterogeneity between studies. Data analysis was performed by CMA software (Version 2).

Results

Finally, 22 articles included in this review. The overall effect for body weight at discharge was found to be statistically significant in the prefeeding oral stimulation (PFOS) (SDM = 7.91, 95% CI: 5.62, 10.2, p = 0.000, I 2 = 86.31) and Premature Infant OMI (PIOMI) (SDM = 3.71, 95% CI: 0.72, 6.69, p = 0.01, I 2 = 96.64) groups versus control group. The overall effect of independent oral feeding was significant for PFOS-only (SDM = -0.64, 95% CI: -1.1, -0.17, p = 0.007, I 2 = 75.45), PIOMI only (SDM = -1.48, 95% CI: -2.49, -0.46, p = 0.004, I 2 = 93.73) and nonnutritive sucking (NNS) only (SDM = -0.53, 95% CI: -0.76, -0.30, p = 0.001, I 2 = 0) groups versus control groups. The overall effect of length of hospital stay was significant for NNS group (SDM = -0.45, 95% CI: -0.67, -0.23, p = 0.067, I 2 = 0) and PIOMI group (SDM = -0.42, 95% CI: -0.69, -0.15, p = 0.002, I 2 = 20.18) versus control group.

Conclusion

Among OMIs, the PIOMI approach generally exhibited a more favorable impact on body weight gain at discharge, the duration required to achieve independent oral feeding, and the length of hospital stay.

Effect of Thoracic Squeezing Technique and Expiratory Flow Increase Technique on Neonates With Neonatal Respiratory Distress Syndrome: A Case Report

Neonatal respiratory distress syndrome (NRDS) is a major cause of morbidity and death in premature newborns due to inadequate surfactant synthesis in the lungs. Preterm birth carries a higher risk of respiratory problems. Clinically cyanosis, grunting, retractions, and tachypnea are signs of early respiratory distress associated with RDS Should therapeutic measures not be implemented, the infant may suffer respiratory failure and increasing hypoxia. This case study investigates how physical therapy affects a preterm newborn with NRDS regarding thoracic squeeze, percussion, and vibration with expiratory flow increase technique The patient's prenatal, natal, and postnatal history is included in depth in the report, along with information on the mother's health, pregnancy difficulties, birth details, first clinical presentation, and care that followed. Despite advancements in treatment through the use of surfactants, prenatal corticosteroids, and advanced respiratory care for the newborn, RDS continues to be the leading cause of morbidity and mortality in premature newborns. The significance of interdisciplinary methods in improving the care and prognosis of newborns with NRDS is shown by this instance.

A swallowing and breastfeeding intervention programme for small and sick neonates embedded in kangaroo mother care

Available evidence of oral sensorimotor interventions for small neonates is not strong. Evidence of interventions for sick term neonates is largely lacking. Studies are limited by risk of bias and inconsistency. Evidence of interventions relying on a single stimulation technique only appears to be low to very low. Ongoing research is required.Contribution: We describe a five-component neonatal swallowing and breastfeeding intervention programme embedded in the practice of kangaroo mother care (KMC). Drawing on oropharyngeal physiology, neonatology, neurodevelopmental care, breastfeeding- and KMC science, the programme is the product of collaboration between a speech-language therapist and a medical doctor, and their team. Its implementation is dependent on coaching mothers and the neonatal care team. Researchers are invited to determine outcomes of the programme.

Effectiveness of Oral-Motor Stimulation on Oral Feeding in Premature Infants: A Protocol for Systematic Review and Meta-Analysis of Controlled Randomized Trials

Objectives

Premature infants (born before 37 weeks of gestational age) frequently experience feeding difficulties due to underdeveloped oral motor skills and poor chewing, swallowing, and breathing coordination. In order to improve oral feeding efficiency in these infants, Oral-Motor Stimulation (OMS) has been used in various studies. This systematic review study will aim to assess the effectiveness of OMS for oral feeding in preterm infants.

Materials & Methods

The authors will follow the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. They will conduct a search in electronic databases, including PubMed, Scopus, Web of Science, Cochrane Central Register of Controlled Trials in The Cochrane Library (CENTRAL), Medline via PubMed, and Cumulative Index to Nursing and Allied Health Literature (CINAHL) for nursing and related healthcare texts without language restrictions from the first month of 1991 to the fifth month of 2024 to achieve the study objectives. All Randomized Controlled Clinical Trials (RCT) examining the effect of OMS on oral feeding in preterm infants will be included in this study.

Results

The primary outcome of this systematic review will be oral feeding, and the secondary outcomes will include duration of hospitalization, weight gain, and feeding efficiency. Two independent reviewers will select and extract data for the study. The Cochrane Risk of Bias Tool (RoB2) will be used to evaluate potential biases in the study. Publication bias will be evaluated using funnel plots, Begg's, and Egger's tests. The degree of heterogeneity among the studies will be assessed using the I2 statistic and the χ2 test. Analyses of subgroups will also be carried out. All meta-analyses will be conducted using Stata V.14.

Conclusion

This systematic review protocol for preterm infants will aim to promote evidence-based decision-making and support the development of clinical practice guidelines in preterm feeding.

A Single-Subject Study to Consider the Premature Infant Oral Motor Intervention Combined with Kinesio-Tape in Premature Infants with Feeding Problems

Background

The survival rate in premature infants (PIs) has increased, but many have medical and developmental complications. Difficulty with sucking, swallowing, and poor nourishment are common complications. This study aimed to investigate the effects of Kinesio-tape (KT) combined with premature infant oromotor intervention (PIOMI) on feeding efficiency (mean volume intake [%MV]), oromotor skills (Preterm Oral Feeding Readiness Assessment Scale [POFRAS]), and weight gain in PIs.

Methods

In this single-subject study, 5 PIs with feeding problems were received the PIOMI-KT for 7 consecutive days. The main outcome measure was the POFRAS scale. The %MV and weight gain were the secondary outcome measures. Measurements were taken before treatment (T0), after the 4th session (T1), and after the 7th session (T3).

Results

The POFRAS scores, %MV, and weight gain improved in all infants after treatment. The maximum and minimum change in level between the baseline and treatment phase was +26 and+16 for POFRAS, +54 and, +34 for %MV, +180, and +100 for weight gain. The treatment trend was upward for all infants and shown by the directions of the slopes indicated by positive values. The feeding problems were resolved in all infants after the 7th treatment session.

Conclusion

The combination therapy of PIOMI-KT improved feeding function in PIs.

Effect of Neonatal Unit Interventions Designed to Increase Breastfeeding in Preterm Infants: An Overview of Systematic Reviews

INTRODUCTION

This overview aims to systematically review evidence regarding effects of interventions undertaken in neonatal units to increase breastfeeding in preterm infants.

METHODS

We followed Cochrane methodology. Systematic reviews published to October 31, 2022, reporting meta-analysis of effects from original studies on breastfeeding rates in preterm infants of neonatal unit interventions designed to increase breastfeeding were included.

RESULTS

Avoidance of bottles during breastfeed establishment (comparator breastfeeds with bottle-feeds) demonstrated clear evidence of benefit for any breastfeeding at discharge and exclusive breastfeeding 3 months post-discharge, and possible evidence of benefit for exclusive breastfeeding at discharge, and any breastfeeding post-discharge. Kangaroo mother care (KMC) (comparator usual care) demonstrated clear evidence of benefit for any and exclusive breastfeeding at discharge and possible benefit for any breastfeeding post-discharge. Quality improvement (QI) bundle(s) to enable breastfeeds (comparator conventional care) showed possible evidence of benefit for any breastfeeding at discharge. Cup feeding (comparator other supplemental enteral feeding forms) demonstrated possible evidence of benefit for exclusive breastfeeding at discharge and any breastfeeding 3 months after. Early onset KMC (commenced <24 h post-birth), oral stimulation, and oropharyngeal colostrum administration, showed no evidence of benefit. No meta-analyses reported pooled effects for gestational age or birthweight subgroups.

CONCLUSION

There is ample evidence to support investment in KMC, avoidance of bottles during breastfeed establishment, cup feeding, and QI bundles targeted at better supporting breastfeeding in neonatal units to increase prevalence of breastfeeding in preterm infants and promote equal access to breastmilk. Stratifying effects by relevant subgroups is a research priority.
