Oral feeding practices and discharge timing for moderately preterm infants

Novel classification of foramen magnum meningiomas predicted by topographic position relative to neurovascular bundle

PURPOSE

Proximity to critical neurovascular structures can create significant obstacles during surgical resection of foramen magnum meningiomas (FMMs) to the detriment of treatment outcomes. We propose a new classification that defines the tumor's relationship to neurovascular structures and assess correlation with postoperative outcomes.

METHODS

In this retrospective review, 41 consecutive patients underwent primary resection of FMMs through a far lateral approach. Groups defined based on tumor-neurovascular bundle configuration included Type 1, bundle ventral to tumor; Type 2a-c, bundle superior, inferior, or splayed, respectively; Type 3, bundle dorsal; and Type 4, nerves and/or vertebral artery encased by tumor.

RESULTS

The 41 patients (range 29-81 years old) had maximal tumor diameter averaging 30.1 mm (range 12.7-56 mm). Preoperatively, 17 (41%) patients had cranial nerve (CN) dysfunction, 12 (29%) had motor weakness and/or myelopathy, and 9 (22%) had sensory deficits. Tumor type was relevant to surgical outcomes: specifically, Type 4 demonstrated lower rates of gross total resection (65%) and worse immediate postoperative CN outcomes. Long-term findings showed Types 2, 3, and 4 demonstrated higher rates of permanent cranial neuropathy. Although patients with Type 4 tumors had overall higher ICU and hospital length of stay, there was no difference in tumor configuration and rates of postoperative complications or 30-day readmission.

CONCLUSION

The four main types of FMMs in this proposed classification reflected a gradual increase in surgical difficulty and worse outcomes. Further studies are warranted in larger cohorts to confirm its reliability in predicting postoperative outcomes and possibly directing management decisions.

Premature Babies Can Be Cared for in the Maternity Ward without an Increased Risk and Discharged with a Feeding Tube If Necessary

In general, premature babies are discharged home when they reach full self-feeding. We established a discharge management protocol which allows for discharging late preterm babies with a feeding tube if necessary. This retrospective study included 108 preterm infants (34+ weeks) born in 2019 and 2020. The preterm infants discharged with a feeding tube (n = 32) were born at 35.23 weeks' gestation (±0.884), with a birth weight of 2423 g (±375.1), and were discharged at 7.22 days (±3.63) and had a weight of 3466 g (±591.3) at the first outpatient visit around the expected birth date. The preterm infants discharged without a feeding tube were born at 35.97 weeks' gestation (±0.702) with a birth weight of 2589 g (±424.84), discharged home at 6.82 days (±7.11) and a weight of 3784 g (±621.8) at the first outpatient visit. The gestational week and birth weight were statistically significantly different between the groups, with a p-value of <0.001 for each, and the length of hospital stay (p = 0.762) and weight at follow-up (p = 0.064) did not significantly differ. No infant required tube-feeding at the time of the first outpatient visit, i.e., the time of expected birth. Therefore, with well-thought-out management, it is possible and safe to discharge preterm infants home with a feeding tube.

Bolus Feeding Via Gastric Versus Oral Routes in Very Preterm Neonates

BACKGROUND

We intend to investigate the association of bolus orogastric tube (BOG) and nipple bottle (N) feedings with postnatal growth in very premature neonates (VPN: gestational age between 28 and 33 weeks).

MATERIAL AND METHODS

The days of life (DOL) to achieve full combined oral and gastric enteral nutrition (FEN) and attain body weight (BW) of 2200 g (Wt22) and the length of hospitalization (LOH) were retrospectively associated with clinical and BOG and N feeding-related variables via multivariate regression analyses. Correlations were performed to ascertain the strength of associations.

RESULTS

In a cohort of 127 VPN, FEN demonstrated negative associations with gestational age (GA) and LOH and Wt22 with birth weight (BW). FEN showed positive associations with nil by mouth and intravenous fluid-nutrition days and with DOL to start and achieve full nipple feeding. LOH was associated with days on antibiotics and DOL to start and achieve full nipple feeding. Wt22 was associated with DOL to achieve full nipple feeding. The start day of BOG feeding had no independent associations and weak, highly significant positive correlations with Wt22, LOH, and FEN.

CONCLUSION

Bolus orogastric tube feeding has no independent implications for postnatal growth, duration of hospitalization, or chronological age to attain full enteral nutrition in VPN unless combined with nipple feeding to provide enteral nutrition. Oral bottle feeding accelerates postnatal catch-up growth and full enteral nutrition acquisition while reducing hospitalization duration. Initiating nipple feeding at 32 weeks of postmenstrual age may be safe in stable VPN. Antibiotic therapy increases hospitalization duration.

A Unique Clinical Tool for the Evaluation of Oral Feeding Skills in Infants

Background. Occupational therapy practice for oral feeding assessment is based on clinical observation of infants' sucking, swallowing, and breathing ability, which is influenced by clinical experience and provides poor evidence on explanatory factors. Purpose. To test the clinical utility and safety of a nipple monitoring device for the quantitative evaluation of oral feeding skills. Method. Sixteen infants, with no severe medical complications, participated in a pre-experimental pilot study. Oral feeding performances (duration, intake volume, and rate of transfer), and occurrence of adverse events (apnea, bradycardia, and oxygen desaturations) were recorded to ensure the tool does not interfere with infant's feeding ability or does not create any adverse effects. Findings. There was no significant difference in duration, intake volume, rate of transfer between the two monitored sessions, and no occurrence in adverse events. Implications. The findings suggest that the nipple monitoring device may be used for quantitative assessment and intervention planning of oral feeding difficulties in infants.

Effect of cue-based feeding on time to nipple feed and time to discharge in very low birth weight infants

The objective of this study is to evaluate the effectiveness of a cue-based feeding protocol in improving time to nipple feed and time to discharge in very low birth weight infants in a Level III Neonatal Intensive Care Unit. Demographic, feeding, and discharge data were recorded and compared between the two cohorts. The pre-protocol cohort included infants born from August 2013 through April 2016 and the post-protocol cohort included infants born from January 2017 through December 2019. 272 infants were included in the pre-protocol cohort and 314 infants in the post-protocol cohort. Both cohorts were statistically comparable in gestational age, gender, race, birthweight, prenatal care, antenatal steroid use, and rates of maternal diabetes. There were statistically significant differences between the pre- versus post-protocol cohorts in median post-menstrual age (PMA) in days at first nipple feed (PO) (240 vs 238, p = 0.025), PMA in days at full PO (250 vs 247, p = 0.015), and length of stay in days (55 vs 48, p = 0.0113). Comparing each year in the post-protocol cohort, for each outcome measure, a similar trend was noted in 2017 and 2018, but not in 2019. In conclusion, the cue-based feeding protocol was associated with a decrease in the time to first PO, time to full nipple feeds, and the length of stay in very-low-birthweight infants.

Oral Feeding Outcomes in Infants Born With Neonatal Abstinence Syndrome

OBJECTIVE

Breastfeeding is the optimal source of nutrition for all infants, but there are limited data on feeding outcomes in infants with neonatal abstinence syndrome (NAS) who are admitted in the neonatal intensive care unit (NICU).

METHODS

A retrospective cohort study was conducted at a level II/III NICU. Study sample consisted infants with a diagnosis of NAS and those diagnosed with respiratory distress syndrome. The primary outcome was attainment of independent oral feeds, defined as the number of days to transition from full-tube to full oral feeds. Secondary outcomes included length of hospital stay and method (breast or bottle) of oral feeds at the start, at attainment of independent oral feeds, and at hospital discharge.

RESULTS

Infants with NAS took significantly longer to attain independent oral feeds than controls (P = .021) and received significantly fewer breastfeeds at the start of oral feeds, at independent oral feeds, and at hospital discharge (P = .000). There was no difference in length of hospital stay between groups.

CONCLUSION

These results suggest that infants with NAS can experience difficulties achieving independent oral feeds and are less likely to receive breastfeeds. Additional support is required to enhance oral feeds in infants with NAS in the NICU.

Contributions of the NICHD neonatal research network's generic database to documenting and advancing the outcomes of extremely preterm infants

The Eunice Kennedy Shriver National Institute of Child Health and Human Development Neonatal Research Network (NRN) maintains a database of extremely preterm infants known as the Generic Database (GDB). Begun in 1987, this database now includes more than 91,000 infants, most of whom are extremely preterm (<29 weeks gestation). The GDB has been the backbone of the NRN, providing high quality, prospectively collected data to study the changing epidemiology of extreme prematurity and its outcomes over time. In addition, GDB data have been used to generate hypotheses for prospective studies and to develop new clinical trials by providing information about the numbers and characteristics of available subjects and the expected event rates for conditions and complications to be studied. Since its inception, the GDB has been the basis of more than 200 publications in peer-reviewed journals, many of which have had a significant impact on the field of neonatology.

Risk Factors Associated With Long-term Feeding Problems in Preterm Infants: A Scoping Review

BACKGROUND

Infants who are born preterm are at a high risk of encountering feeding problems.

PURPOSE

The aim of this scoping review is to identify risk factors associated with feeding problems that persist beyond infancy in children (aged 1-6 years) who were born preterm (<37 weeks' gestation).

METHODS

To perform this scoping review, the Preferred Reporting Items for Systematic Reviews and Meta-Analyses framework was applied. To be included in this study, articles had to be published in peer-reviewed journals, had an empirical study design, examined feeding problems relating to the child's feeding ability or refusal to eat certain texture of foods, and assessed risk factors (age, weight, and medical conditions) associated with long-term feeding problems in children who were born preterm.

RESULTS

After abstract and full-text screening, a total of 9 articles meeting the inclusion criteria were included in this study. Findings from this study identified that gestational age and birth weight are significant risk factors and that sex, duration of mechanical ventilation, and length of tube feedings are potential risk factors.

IMPLICATIONS FOR PRACTICE

This study confirms that younger and smaller infants are at a high risk of encountering oral feeding difficulties and early interventions services should be focused on these preterm infants.

IMPLICATIONS FOR RESEARCH

Evaluation of timing and intensity (dose) of early interventions strategies should be investigated to provide more targeted and effective interventions for younger and smaller preterm infants.

Improving Time to Independent Oral Feeding to Expedite Hospital Discharge in Preterm Infants

BACKGROUND AND OBJECTIVES

Achievement of independent oral feedings remains the most common barrier to discharge in preterm infants. Early oral feeding initiation may be associated with a lower postmenstrual age (PMA) at independent oral feeding and discharge. In preterm infants born between 25 and 32 weeks' gestation, our aim was to decrease the PMA at independent oral feedings and discharge by 1 week between June 2019 and June 2020.

METHODS

Following formation of a multidisciplinary team, the following plan-do-study-act cycles were targeted: (1) oral feeding initiation at <33 weeks' PMA, (2) cue-based feeding, and (3) practitioner-driven feeding in infants who had not yet achieved independent oral feedings by 36 weeks' PMA. Outcome measures included the PMA at independent oral feeding and discharge. Process measures included adherence to cue-based feeding assessments and PMA at oral feeding initiation.

RESULTS

In total, 552 infants with a median gestational age of 30.3 weeks' (interquartile range 28.1-32.0) and birth weight of 1320 g (interquartile range 1019-1620) were included. The PMA at discharge decreased from 38.8 to 37.7 weeks during the first plan-do-study-act cycle, which coincided with an increase in the number of infants initiated on oral feeds at <33 weeks' PMA from 47% to 80%. The age at independent oral feeding decreased from 37.4 to 36.5 weeks' PMA.

CONCLUSIONS

In preterm infants born between 25 and 32 weeks' gestation, earlier oral feeding initiation was associated with a decreased PMA at independent oral feeding and discharge.

Safety and efficacy of a home nasogastric monitoring program for premature infants

BACKGROUND

A novel home monitoring program, in which premature infants are cared for at home with a nasogastric tube in place prior to achievement of full oral feeding, was evaluated. The program combines a digital, fully EMR-integrated, virtual daily rounding platform with direct provider video and telephone contact.

METHODS

A case-control study was performed evaluating infants <  34 weeks' gestation who were followed in our program. A historical control group, was created by matching 2 : 1 based on gestational age±6 days, retroactively.

RESULT

15 patients discharged in the program were compared with 30 controls. The home cohort gained an average of 30 g/day compared with the in-hospital group at 27g/day (p = 0.325). The home group required a mean of 5.9±2.9 days to full oral feeding once discharged, not different from the control group at 5.4±3.7 days (p = 0.606). The percentage of oral feeds for the home cohort, however, increased at a rate of 12.2%before discharge compared to rising 57%at home (p <  0.001). The control group spent an additional 8.1±3.9 days in the hospital after reaching criteria. There were no reported adverse events or readmissions.

CONCLUSION

Premature infants can safely advance oral feeds using a home monitoring program. While at home, infants gained weight similarly to their inpatient controls inpatient, yet gained full oral skills at a significantly faster rate compared to when they were in the hospital.

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.

Implementation of Cue-Based Feeding to Improve Preterm Infant Feeding Outcomes and Promote Parents' Involvement

OBJECTIVE

To implement cue-based feeding for preterm infants and to assess its effects on time to achieve full oral feedings, length of stay, and parents' involvement in the feeding process.

DESIGN

A quality improvement project with a pre-post evidence-based practice implementation design.

SETTING

Level III NICU in a quaternary hospital in the U.S. Northeast.

PARTICIPANTS

Medical records of preterm infants from 23 0/7 weeks to 31 6/7 weeks gestational age who were eligible for initiation of oral feeding.

INTERVENTION/MEASUREMENTS

We implemented cue-based feeding through staff education and training. We completed a retrospective review of the medical records of 82 preterm infants before implementation and 167 preterm infants after implementation for the outcomes of time to achieve full oral feedings, length of stay, and parents' involvement in the feeding process.

RESULTS

For infants 23 0/7 weeks to 27 6/7 weeks gestation, time to achieve full oral feedings decreased by 7 days, length of stay decreased by 4.4 days, and parents' involvement in the feeding process increased by 80% from before to after implementation. For infants 28 0/7 weeks to 31 6/7 weeks, time to achieve full oral feedings decreased by 6.6 days, length of stay decreased by 2.7 days, and parents' involvement in the feeding process increased by 49% from before to after implementation. The organization saved $103,950 per year by decreasing length of stay.

CONCLUSIONS

Cue-based feeding decreased time to achieve full oral feedings, decreased length of stay, increased parents' involvement in the feeding process, and resulted in cost savings for the institution.

Oral-feeding guidelines for preterm neonates in the NICU: a scoping review

OBJECTIVE

This scoping review describes the nature and evidence base of internationally available guidelines for the introduction of oral feeding for preterm infants in neonatal units.

STUDY DESIGN

Thirty-nine current infant oral feeding introduction guidelines were obtained, and their recommendations contrasted with available scientific literature.

RESULT

Documents were primarily from the USA, UK, Canada, and Australia, from hospitals, regional health authorities, and journal articles. Specifics of nonnutritive sucking, gestational age at first feed, exclusions to oral feeding, suggested interventions, and the definition of full oral feeding varied between documents. There was variable use of scientific evidence to back up recommendations.

CONCLUSION

Guidelines for oral feeding, whether written by clinicians or researchers, vary greatly in their recommendations and details of interventions. Areas more widely researched were more commonly discussed. Recommendations varied more when evidence was not available or weak. Guideline developers need to synthesize evidence and local variability to create appropriate guidelines.

Quantitative assessment of nutritive sucking patterns in preterm infants

OBJECTIVE

To assess patterns of nutritive sucking in very preterm infants ≤32 weeks of gestation.

STUDY DESIGN

Very preterm infants who attained independent oral feeding were prospectively assessed with an instrumented feeding bottle that measures nutritive sucking. The primary outcome measure was nutritive sucking performance at independent oral feeding.

RESULT

We assessed nutritive sucking patterns in 33 very preterm infants. We recorded 63 feeding sessions. The median number of sucks was 784 (IQR: 550-1053), the median sucking rate was 36/min (IQR: 27-55), and the median number of sucking bursts during the first 5 min of oral feeding was 14 (IQR: 12-16). Maximum sucking strength correlated with the number of sucks (r = 0.62; p < 0.01). No safety concerns were identified during the study.

CONCLUSION

The quantitative analysis of nutritive sucking patterns with a newly developed instrumented bottle in stable, very preterm infants is safe and feasible. More research is needed to develop and refine the instrument further.

Safety and Parental Satisfaction With Early Discharge of Preterm Infants on Nasogastric Tube Feeding and Outpatient Clinic Follow-Up

Aim: To evaluate our early discharge program of preterm infants with nasogastric tube feeding (NTF) and close outpatient clinic follow-up with regard to safety, parent satisfaction and parental stress level. Methods: 119 preterm infants were discharged on NTF from our tertiary care neonatal unit (median gestational age 31.0 weeks, median birthweight 1,650 g). Parental satisfaction was evaluated by a standardized questionnaire. For safety assessment growth until term equivalent age and re-hospitalizations within 2 months after discharge were evaluated. Results: Infants were discharged home at a median gestational age of 35.4 weeks after a median hospital stay of 22 days. Follow up was attained in 95 of 104 parent-infant dyads. The majority of parents (94%) reported that they had made the right decision in taking their infant home on NTF. At the time of discharge 86% of parents felt very well-prepared to perform NTF. 70% Of parents rated their stress level at home as low (≤2 out of 5). There were no NTF associated readmissions and no growth faltering until term equivalent age. Conclusion: Early discharge of preterm infants with NTF together with outpatient clinic follow-up is very well-accepted by parents and appears to be safe.

Inadequate oral feeding as a barrier to discharge in moderately preterm infants

OBJECTIVES

The objectives describe the frequency that inadequate oral feeding (IOF) is the reason why moderately preterm (MPT) infants remain hospitalized and its association with neonatal morbidities.

STUDY DESIGN

Prospective study using the NICHD Neonatal Research Network MPT Registry. Multivariable logistic regression was used to describe associations between IOF and continued hospitalization at 36 weeks postmenstrual age (PMA).

RESULT

A total of 6017 MPT infants from 18 centers were included. Three-thousand three-seventy-six (56%) remained hospitalized at 36 weeks PMA, of whom 1262 (37%) remained hospitalized due to IOF. IOF was associated with RDS (OR 2.02, 1.66-2.46), PDA (OR 1.86, 1.37-2.52), sepsis (OR 2.36, 95% 1.48-3.78), NEC (OR 16.14, 7.27-35.90), and BPD (OR 3.65, 2.56-5.21) compared to infants discharged and was associated with medical NEC (OR 2.06, 1.19-3.56) and BPD (OR 0.46, 0.34-0.61) compared to infants remaining hospitalized for an alternative reason.

CONCLUSION

IOF is the most common barrier to discharge in MPT infants, especially among those with neonatal morbidities.
