Caregiver experiences of oral feeding in infants on long-term high flow nasal cannula support

Purpose Navigating the feeding journey of medically complex infants on long-term high flow nasal cannula support can be challenging for caregivers, especially given inconsistencies in clinical practice for oral feeding on high flow nasal cannula support. The aim of this study was to explore the perspectives of caregivers who have experienced this journey, to inform best practice care. Method This study used a generic qualitative inquiry approach. Semi-structured interviews were conducted with seven caregivers of children who had been on long-term high flow nasal cannula support as infants during 2021. Reflexive thematic analysis was used to generate meaning-united stories. Result All caregivers reported oral feeding difficulties that persisted beyond hospitalisation, resulting in demanding mental loads and care arrangements. Caregivers described how these difficulties were often exacerbated by complex medical needs and the strategies they experimented with to support oral feeding. Caregiver’s experiences in the healthcare system were characterised by inconsistencies in care pathways and variable access to specialist feeding services. The importance of a collaborative relationship with healthcare professionals and a conducive hospital environment were also highlighted. Conclusion The oral feeding journey for families with infants on long-term high flow nasal cannula support was characterised by multifaceted challenges and implications. Further research is required to establish and provide consistent, family-centred, and evidence-based care for this population.

A parent-administered sensorimotor intervention for oral feeding in infants born preterm: A randomized clinical study.

To evaluate the effect of a parent-administered sensorimotor intervention (PASI) program on developmental outcomes of infants born preterm during their stay in the neonatal intensive care unit (NICU). A randomized clinical study was conducted with 94 infants (mean gestational age 31 weeks [SD 2.2 weeks]; 1658 g [SD 478 g]; 49 males, 45 females) initially enrolled and randomly assigned to an experimental or a control group. Infants in the experimental group received a PASI, consisting of tactile input to oral structures, trunk/limbs, and non-nutritive sucking for 15 minutes, once a day, for 10 days. Infants in the control group received standard care. Outcomes included attainment of complete oral feeds, occurrence of direct breastfeeding at hospital discharge, and motor function assessed using the Test of Infant Motor Performance (TIMP). A total of 80 infants completed the study. Infants in the experimental group achieved complete oral feeds sooner (11.9 [SD 4.3] vs 15.3 [SD 6.5] days, p = 0.013), and a greater number of them received direct breastfeeds (22 vs 12, p = 0.010) than controls. Infants in both groups had equivalent motor functions scores on the TIMP (46.9 [SD 4.8], 46.8 [SD 8.4], p = 0.961). A PASI program may enhance an infant's oral feeding skills. These findings provide evidence to advocate for the institution of PASI in NICUs.

Characterizing Biomarkers of Continuous Peristalsis and Bolus Transit During Oral Feeding in Infants at pH-Impedance Evaluation: Clinical and Research Implications

ObjectiveTo examine the biomarkers of pharyngoesophageal swallowing during oral feeding sessions in infants undergoing pH-impedance testing and determine if swallow frequencies are distinct between oral- and partially oral-fed infants. Study designOne oral feeding session was performed in 40 infants during pH-impedance studies and measurements included swallowing frequency, multiple swallow rate, air and liquid swallow rates, esophageal swallow clearance time (ESCT), and gastroesophageal reflux (GER) characteristics. Linear and mixed statistical models were applied to examine the swallowing markers and outcomes. ResultsInfants (30.2 ± 4.4 weeks birth gestation) were evaluated at 41.2 ± 0.4 weeks postmenstrual age (PMA). Overall, 10,675 swallows were analyzed during the oral feeding sessions (19.3 ± 5.4 min per infant) and GER events were noted (2.5 ± 0.3 per study). Twenty-four-hour acid reflux index (ARI) was 9.5 ± 2.0%. Differences were noted in oral- and partially oral-fed infants for: volume consumption (p<0.01), consumption rate (p<0.01), and length of hospital stay in days (p<0.01). Infants with ARI >7% had greater frequency of swallows (p=0.01). The oral-fed group had greater ARI (12.7 ± 3.3%, p=0.05). ConclusionsOropharyngeal swallowing regulatory characteristics decrease over the feeding duration and were different between ARI >7% vs ≤7%. Although GER is less in infants who are partially oral-fed, the neonates with increased acid exposure achieved greater oral intakes and shorter hospitalizations, despite the presence of comorbidities. Pharyngoesophageal stimulation as during consistent feeding or GER events can activate peristaltic responses and rhythms, which may be contributory to the findings.

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

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). Single-center QI to introduce oral feeding to infants on high-flow nasal cannula (HFNC) by reducing the flow to 2 L during feeds. To reduce PMA at first oral feeding and reduce the LOS. To introduce oral feeds in 40% of infants who are on ≤4 L HFNC by the end of 12 months. 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). Allowing oral feeding in infants while on HFNC is feasible. This approach can significantly reduce PMA at first and full oral feeding.

Effect of Select Nutraceuticals on Transitioning from Tube Feeding to Oral Feeding in Infants

This study investigated the effects of oral feeding readiness assessments on nutraceutical therapies in infants admitted to neonatal intensive care units. Nutraceuticals are increasingly being used to promote newborn health. However, their effects on feeding transitions and developmental outcomes have not been thoroughly studied. Therefore, this study was conducted on 210 infants to explore the effect of nutraceutical therapies on the rate of successful eating transitions and the incidence of feeding-related problems. Data on age, gender, birth weight, delivery technique, and nutraceutical use were also collected. Successful transitions, delayed transitions, and complications such as aspiration and feeding intolerance were recorded. The findings indicated that infants who received nutraceutical therapies achieved a higher success rate in transitioning to feeding, with a statistically significant difference in outcomes compared to those who did not. Probiotics improved gastrointestinal well-being and decreased challenges during dietary changes. Omega-3 supplements and vitamin D exhibited favorable effects, aiding smooth transitions and reducing hospital readmissions. This study revealed that age and feeding technique significantly influenced the success of transitions. Incorporating nutraceuticals into feeding protocols can result in better outcomes in neonatal ICUs.

Effect of oral stimulation in improving feeding performance of pre-term infants in NICU: A systematic review

Aim: The Aim of this systematic review is to evaluate the effectiveness of oral stimulation techniques in improving feeding performance among pre-term infants in neonatal intensive care units (NICUs). Method: We conducted a comprehensive literature search of electronic databases, including PubMed, CINAHL, and Cochrane Library, from 2010-2021. Studies were included if they investigated the effect of oral stimulation on feeding performance outcomes such as time to full enteral feeding, weight gain, and length of hospital stay. Two reviewers independently assessed the quality of the studies using the Cochrane risk-of-bias tool and extracted data using a standardized data extraction form, and data were synthesized using a narrative approach due to heterogeneity in study design and outcome measures. Result: Our search identified 10 studies that met the inclusion criteria, consisting of randomized controlled trials, quasi-experimental studies, and case series. Eight studies reported significant improvements in feeding performance outcomes with the use of oral stimulation interventions compared to standard care or placebo. The remaining two studies reported mixed findings or no significant differences between groups. Overall, the quality of evidence was low to moderate due to methodological limitations and inconsistency in outcome reporting. Our findings suggest that oral stimulation techniques such as non-nutritive sucking, pacifier-activated device, and oral motor exercises are effective in improving feeding performance among pre-term infants in NICUs. These techniques were associated with reduced time to achieve full oral feeds, shortened hospital stay, and improved weight gain compared to control groups. Conclusion: The results of this systematic review suggest that oral stimulation may be an effective intervention for improving feeding performance in pre-term infants in NICUs. However, further research is needed to establish the optimal timing, frequency, and duration of oral stimulation interventions, as well as their long-term effects on growth and development. Future studies should also address methodological limitations, such as small sample sizes and lack of blinding, to improve the quality of evidence in this field. Significance of the study: Oral feeding is a difficult job for premature infants those who are admitted to NICU. Because of poor muscle tone, underdeveloped oral motor skills and reduced suck-swallow-breathe synchronization, they are unable to commence feeds from the bottle and breast immediately after birth, unlike full-term infants. As long as oral feeding is not developed, a number of non-oral feeding methods are employed which feeding methods can cause severe side effects 1. The primary barrier to oral feeding in infants with gestational age less than 34 weeks is the lack of coordination in sucking, swallowing, and breathing. Oral feeding in these infants can cause apnoea, decreased pulse oximetry, transient bradycardia, and aspiration. Therefore, in neonates those who do not reach the gestational age of 34 weeks for them bottle or breastfeeding are not considered, and developmental transition from gavage to oral feeding in a 28-week-old infant may take 6 weeks or longer. Several studies have shown that oral motor intervention on infants less than 34 weeks results in decreased transition time from gavage to oral feeding 2.

Oral Feeding in Infants After Congenital Diaphragmatic Hernia Repair While on Non-invasive Positive Pressure Ventilation: The Impact of a Dysphagia Provider-Led Protocol.

Infants with congenital diaphragmatic hernia (CDH) who require non-invasive positive pressure ventilation or high flow nasal cannula are at risk for aspiration and delayed initiation of oral feeding. We developed a dysphagia provider-led protocol that involved early consultation with an occupational therapist or speech/language pathologist and modified barium swallow study (MBSS) to assess for readiness for oral feeding initiation/advancement on non-invasive positive pressure ventilation. The objective of this study was to retrospectively compare this intervention cohort to a historical control cohort to evaluate the protocol's impact on the time to initiate oral feeding. We describe the development and implementation of the protocol, the MBSS findings of the intervention cohort, and compared the control (n = 64) and intervention (n = 37) cohorts using Fischer's exact test and Mann-Whitney test. We found that both cohorts had similar prenatal and neonatal characteristics including age at extubation. Significantly more infants in the intervention cohort were on non-invasive positive pressure ventilation or high flow nasal cannula at the time of oral feeding initiation (84% vs. 28%, p < 0.0001). None of the control cohort infants underwent MBSS while on respiratory support. Of the intervention cohort, 15 infants underwent a MBSS while on non-invasive positive pressure ventilation; 6 had no evidence of laryngeal penetration and/or aspiration during swallowing. Infants in the control cohort initiated oral feeds significantly sooner after extubation (6 versus 11days, p = 0.001) and attained full oral feeds earlier (20days versus 28days, p = 0.02) than the intervention group. There was no difference in the rate of gastrostomy tube placement (38%). Appropriate monitoring by a dysphagia provider and evaluation with clinical and radiological means are crucial to determine the safety of initiating oral feeding in term infants with CDH. Continued surveillance is needed to determine the long-term impact on oral feeding progression in this population.

Cue-Based Feeding as Intervention to Achieve Full Oral Feeding in Preterm Infants Primarily Managed with Bubble CPAP.

Cue-based feeding aims at matching introduction of per oral (PO) feeding with physiological readiness of preterm infants to facilitate PO intake and avoid oral aversion. It was claimed that cue-based feeding may lead to delay in the initiation or achieving full PO feeding in clinical setting primarily using bubble nasal continuous positive airway pressure (CPAP). The study aimed to examine the association of cue-based feeding with time of introduction and completing oral feeding in infants primarily managed with bubble CPAP. A retrospective analysis where outcomes of preterm infants ≤32 weeks' gestational age (GA) and ≤2,000 g birth weight (BW) were compared after a practice change from volume-based feeding advancement to cue-based feeding. Continuous variables were compared by using t-test and multilinear regression analysis to control for confounding variables. Of the 311 preterm infants who met inclusion and exclusion criteria, 194 were in the cue-based feeding group and 117 were in the volume-based advancement historical comparison group. There were no differences between groups regarding demographic or clinical variables. Postmenstrual age (PMA) of initial feeding assessment was less in the cue-based feeding group. Age of first PO feeding and when some PO was achieved every feed was mildly delayed in the cue-based feeding compared with comparison group, 34 (±1.3) versus 33.7 (±1.2) weeks, and 36.2 (±2.3) versus 36.0 (±2.4) weeks, (p < 0.01) respectively. However, the age of achieving full PO did not differ between groups, 36.8 (±2.2) versus 36.4 (±2.4) weeks (p = 0.13). There was no difference between groups regarding growth parameters at 36 weeks' PMA or at discharge. Similar results were obtained when examining subcategories of infants ≤1,000 g and 1,001 to 2,000 g. Cue-based feeding may not be associated with a delay in achieving full oral feeding or prolongation of the length of stay in preterm infants managed with CPAP. · Cue-based feeding matches introduction of PO feeding with physiological readiness.. · Cue-based feeding may not be associated with a delay in achieving full oral feeding in preterm infants.. · Cue-based feeding is not associated with prolongation of the length of stay in preterm infants.. · Cue based feeding in preterm infants managed with noninvasive bubble CPAP is examined..

Transcutaneous Auricular Vagus Nerve Stimulation-Paired Rehabilitation for Oromotor Feeding Problems in Newborns: An Open-Label Pilot Study.

Neonates born premature or who suffer brain injury at birth often have oral feeding dysfunction and do not meet oral intake requirements needed for discharge. Low oral intake volumes result in extended stays in the hospital (>2 months) and can lead to surgical implant and explant of a gastrostomy tube (G-tube). Prior work suggests pairing vagus nerve stimulation (VNS) with motor activity accelerates functional improvements after stroke, and transcutaneous auricular VNS (taVNS) has emerged as promising noninvasive form of VNS. Pairing taVNS with bottle-feeding rehabilitation may improve oromotor coordination and lead to improved oral intake volumes, ultimately avoiding the need for G-tube placement. We investigated whether taVNS paired with oromotor rehabilitation is tolerable and safe and facilitates motor learning in infants who have failed oral feeding. We enrolled 14 infants [11 premature and 3 hypoxic–ischemic encephalopathy (HIE)] who were slated for G-tube placement in a prospective, open-label study of taVNS-paired rehabilitation to increase feeding volumes. Once-daily taVNS was delivered to the left tragus during bottle feeding for 2 weeks, with optional extension. The primary outcome was attainment of oral feeding volumes and weight gain adequate for discharge without G-tube while also monitoring discomfort and heart rate (HR) as safety outcomes. We observed no adverse events related to stimulation, and stimulation-induced HR reductions were transient and safe and likely confirmed vagal engagement. Eight of 14 participants (57%) achieved adequate feeding volumes for discharge without G-tube (mean treatment length: 16 ± 6 days). We observed significant increases in feeding volume trajectories in responders compared with pre-stimulation (p < 0.05). taVNS-paired feeding rehabilitation appears safe and may improve oral feeding in infants with oromotor dyscoordination, increasing the rate of discharge without G-tube, warranting larger controlled trials.

Factors Associated with Delayed Transition to Oral Feeding in Infants with Single Ventricle Physiology

To describe the duration of time to achieve exclusive oral feeding in infants with single ventricle physiology and to identify risk factors associated with prolonged gastrostomy tube dependence. Single center, retrospective study of infants with single ventricle physiology. The primary outcome was duration of time required to achieve oral feeding. Transition periods were defined as exclusive oral feeding by Glenn palliation (early), by 1year of age (mid), or after 1year of age (late). Seventy-eight infants were analyzed; 46 (59%) were discharged to home with a gastrostomy tube after the initial hospitalization. Overall, 39 infants (50%) achieved early transition, 14 (18%) mid, and 18 (23%) late. The group who achieved early transition had a higher percentage of preoperative oral feeding (P<.01), greater weight-for-age z score at initial discharge (P=.03), shorter initial intensive care unit duration (P<.01), shorter initial hospital length of stay (P<.01), and greater weight-for-age z score at Glenn admission (P=.02). No preoperative oral feeding (OR=0.12, P=.02) and greater number of cardiac medications at initial discharge (OR=3.8, P=.03) were associated with failure to achieve early transition. No preoperative oral feeding (OR=0.09, P=.01) and longer initial intensive care unit duration (OR=1.1, P=.03) were associated with failure to achieve mid transition. Preoperative oral feeding may potentially be a modifiable factor to help improve early transition to oral feeding.

Sniffin' Away the Feeding Tube: The Influence of Olfactory Stimulation on Oral Food Intake in Newborns and Premature Infants.

Because of their immaturity, many premature infants are fed via nasogastric tube. One objective of the neonatal care is to feed infants orally early. The olfactory function of premature infants is developed before birth and odorants have a significant impact on nutrition in infants. The aim of the study was to test whether odor stimulation has a positive effect on the transition from gavage to oral feeding in infants. Participants were premature infants with gestational age of more than 27 weeks, with full or partial gavage feeding, stable vital parameters and without invasive ventilation. Before each feeding procedure an odorant was presented in front of the infant's nose. Infants were randomized into 1 of 3 groups and received either rose odor (not food-associated), vanilla odor (food-associated), or placebo (no odor). The primary outcome of the study was defined as the time until complete oral nutrition. About 150 children born at a postnatal age of 9.5 ± 7.8 days were included in this study. The duration until complete oral nutrition was reached after 11.8 ± 7.7 (vanilla), 12.2 ± 7.7 (rose), and 12.9 ± 8.8 (control) days. A nearly linear relation between odor presentation frequency and effect size was detectable. For infants that received the intervention for more than 66.7% of the time the length of gavage feeding (8 ± 5.4) and hospitalization (11 ± 6.5) was significantly lower in the vanilla group when compared with control (15 ± 7.3 and 21 ± 13.7, respectively). Odor stimulation with vanilla has an impact on oral feeding in premature infants, however the odor has to be presented on regular basis.

Children With Bronchiolitis on High-Flow Nasal Cannula: To Feed or Not Feed, That IsNotthe Only Question

Bronchiolitis remains the single most common cause of hospitalization during the first year of life.1 Although supportive treatment is the cornerstone of bronchiolitis therapy, with excellent recovery in the majority of children,2 clinicians continue to search for new and better treatment strategies. As reflected in the most recent American Academy of Pediatrics clinical practice guidelines for bronchiolitis,1 previously embraced treatment strategies such as ribavirin, chest physiotherapy, systemic glucocorticoids, epinephrine, and β-agonist therapy are not recommended for children with bronchiolitis. Even the stance emphasizing continuous pulse oximetry has been prudently revisited (clinicians may choose not to use it for patients who do not require supplemental oxygen or if oxygen saturation is >90%). However, treatment guidelines have not yet confronted the putative benefits of high-flow nasal cannula (HFNC) in the more severely ill component of the population. There is also no consensus surrounding the propriety of enteral nutrition in infants with bronchiolitis being treated with HFNC. Despite the absence of data showing the efficacy of HFNC in the context of bronchiolitis, the strategy is increasingly being used. For children with accelerating illness, and who display respiratory distress and hypoxemia despite nasal cannula support, HFNC is generally more well tolerated than nasal continuous positive airway pressure devices. In a small trial ( N = 14), HFNC had a demonstrably favorable effect on diaphragmatic contraction in children with bronchiolitis, thereby decreasing the work of breathing.3 Although it is tempting to ascribe a lower rate of intubation4,5 with the use of HFNC, these studies involved historical control subjects, which confounds data interpretation. The first randomized controlled trial to …

High-flow nasal cannula oxygen and nasal continuous positive airway pressure and full oral feeding in infants with bronchopulmonary dysplasia

Retrospective Study of Gabapentin for Poor Oral Feeding in Infants With Congenital Heart Disease.

Infants who experience extended intensive care stays may lose opportunities for learning to eat and may associate eating with pain or discomfort.1 Feeding difficulties affect 40% to 70% of infants with prematurity or complex medical issues.2 Following severe neonatal pain experiences some infants may present with food refusal or early satiety because they experience oral discomfort, odynophagia, dysphagia, or dyspepsia as a consequence of hyperalgesia, sensitization of peripheral nociceptors, and central nervous system activation of nonspecific arousal systems.3,4 Children born with life-threatening cardiac abnormalities who required corrective or palliative heart surgery are at high risk for oral feeding difficulties.5,6 When oral feeding does not advance in a timely fashion after cardiovascular surgery, infants may require gastrostomy feeding tubes with or without fundoplication.7 Drugs for chronic pain have demonstrated great promise in improving oral feeding outcomes in medically complicated children.8,9 The nerve-stabilizing medication gabapentin has been used for chronic neuropathic pain10 and reduced irritability in neurologically impaired children.11 Furthermore, gabapentin appeared to be an effective adjunct to move medically fragile toddlers from tube to oral feedings.8 In the current study, we hypothesized that feeding difficulties may be related to sensory hypersensitivities of the face and mouth, oropharynx, esophagus, and stomach. We aimed to assess the effect of gabapentin on voluntary oral intake in infants following surgery for congenital heart disease. We selected gabapentin because it is not associated with serious cardiovascular side effects.

Absence of Effect of Nasal Continuous Positive Airway Pressure on the Esophageal Phase of Nutritive Swallowing in Newborn Lambs

It is presently recommended that oral feeding be started in premature infants as soon as possible, often at an age at which nasal continuous positive airway pressure (nCPAP) is still required for ventilatory support. Our previous data showed that application of nCPAP up to 10 cmH2O in full-term lambs had no deleterious effect on cardiorespiratory safety, feeding efficiency, or on nutritive swallowing-breathing coordination. Besides fear of swallowing-breathing coordination disturbances, esophageal motility disruption by nCPAP could be a reason to delay oral feeding. To our knowledge, no study has focused on the effects of nCPAP on esophageal motility in the neonatal period. The aim of the present study was therefore to further assess the effects of nCPAP on oral feeding by assessing its effects on the esophageal phase of nutritive swallowing (nutritive esophagodeglutition). Six full-term lambs, ages 2 to 3 days, underwent esophageal multichannel intraluminal impedance-pH monitoring. Lambs were bottle-fed under 2 randomized conditions, namely spontaneous breathing and nCPAP 6 cmH(2)O. Beyond confirmation of unaltered feeding efficiency, analysis of multiple variables measured by impedance monitoring revealed that nCPAP 6 does not alter nutritive esophagodeglutition in any way (nCPAP vs spontaneous breathing, P > 0.1 for all variables). offering further support to neonatologists pleading for initiation of oral feeding in infants still on nCPAP, the present results set the foundations for similar clinical studies in preterm human infants to confirm the absence of effects of nCPAP on nutritive swallowing.

Milk Temperature Influences Esophageal Motility in the Newborn Lamb

Esophageal dysmotility is common in infants. We aimed to evaluate the influence of milk temperature on esophageal motility using multichannel intraluminal impedance-pH monitoring (MII-pH). Five healthy lambs, ages 2 to 3 days, underwent a MII-pH whereas bottle-fed randomly with 50 mL of ewe milk at 26 °C, 38.5 °C, and 41.5 °C. Impedance motility parameters were studied on 5 swallows at each temperature. At 38.5 °C we noted a higher total propagation velocity and a shorter total bolus transit time (TBTT) (P < 0.05). These unique results suggest a potential role of milk temperature alterations in improving oral feeding in infants with esophageal dysmotility.

Die Obstruktionen der oberen Atemwege und ihre Bedeutung für das Schlucken bei Neugeborenen

Oral feeding in infants requires highly integrated sucking, swallowing, and respiratory sequencing controlled by the neurologic system. Rapid neuromuscular coordination of oral, pharyngeal, and esophageal phases of swallowing must be coordinated with respiration in the swallowing process. When obstruction is present in the upper airway secondary to anatomic or physiologic anomalies, disruption to the oral feeding process may occur. The infant will likely be unable to coordinate sucking and swallowing with breathing in an advantageous sequence. Inefficient feeding and difficulty with airway protection during swallowing may have serious implications regarding the infant's respiratory health as well as ability to gain weight adequately. A stable and patent airway is always the first priority in the management of the infant with upper-airway obstruction. Evaluation of the infant's potential for oral feeding may occur simultaneously with the initial evaluation of the degree of airway obstruction or it may occur following medical or surgical intervention for the airway obstruction. The evaluation process and management options for oral feeding will depend upon the method used to establish a patent airway. Clinical assessment by the speech-language pathologist includes a thorough assessment of oral sensory and motor mechanics, recognition of clinical signs and symptoms of swallowing dysfunction, and consideration of referral for instrumental assessment to obtain objective information regarding airway protection and swallowing function. A variety of medical and feeding interventions may be used to help support oral feeding to whatever extent is safe and efficient. Infants with significant oral feeding problems in the presence of airway obstruction may require a period of supplemental tube feeding and non-nutritive oral stimulation.

Feeding-Facilitating Techniques for the Nursing Infant with Robin Sequence

To determine the effectiveness of feeding-facilitating techniques in children with Robin sequence. Hospital de Reabilitação de Anomalias Craniofaciais, University of São Paulo, Bauru, São Paulo, Brazil. Twenty-six children less than 2 months of age with Robin sequence, whose only cause of respiratory obstruction was glossoptosis. Thirteen infants were treated by being placed in the prone position (Group 1), and 13 were treated by nasopharyngeal intubation (Group 2). During hospitalization, the following feeding-facilitating techniques were applied daily to all children: pacifier, massage to relax and anteriorize the tongue, long and soft bottle nipple with original or enlarged hole, global symmetric position, rhythmic movement of the nipple during suction, and insertion of the nipple on the tongue. During the first evaluation, Group 1 patients accepted 36.15 +/- 33.05 mL milk orally within a period of 44.62 +/- 42.94 minutes, whereas Group 2 ingested 20.00 +/- 20.51 mL milk within 30.38 +/- 25.77 minutes. A significant increase (p < .01) in the volume of ingested milk was observed for the two groups at hospital discharge after a mean treatment period of 10.7 days (Group 1: 63.46 +/- 22.58 mL and Group 2: 55.00 +/- 13.07 mL). The mean duration of feeding decreased in the two groups, with a value of 21.54 +/- 7.18 minutes for Group 1 and of 20.28 +/- 8.53 minutes for Group 2. The results showed that feeding-facilitating techniques can foster oral feeding in infants with Robin sequence.

Oral Feeding in the Preterm Infant

After completing this article, readers should be able to: 1. Describe the sequential development of sucking, swallowing, and respiration. 2. Delineate the limitation of an infant’s oral feeding skills at specific times of development to provide realistic expectations for oral feeding performance. 3. Define oral feeding success in preterm infants. 4. Use the current knowledge of preterm infants’ oral motor skills to facilitate and enhance their performance. 5. Enumerate the potential short- and long-term consequences of an infant’s oral feeding aversion for the patient, family, and health professional. Oral feeding issues in preterm infants are a growing concern for neonatologists because attainment of independent oral feeding is one of the prerequisites for hospital discharge. With the increase in survival of infants born continuously more preterm, understanding such issues has a certain urgency. Concerns do not pertain only to difficulties encountered by neonatologists during the birthstay hospitalization, but also by pediatricians and pediatric gastroenterologists who attend to long-term feeding difficulties/disorders, such as oral feeding aversion. Indeed, greater than 40% of patients followed in feeding disorder clinics are former preterm infants. Research over the last decade has begun to shed light on the development of oral feeding skills in these infants as they mature, which has increased understanding of their limited skills at varying postmenstrual ages. Such knowledge is crucial in clinical practice insofar as expectations of these infants’ oral feeding performance must take into account the ever-changing level of maturity of their skills. This article focuses on the development of sucking, swallowing, and respiration (as it pertains to oral feeding) and the coordination of these three functions. Additional factors, separate from infant feeding skills, also are discussed because they can affect oral feeding performance. This review examines information gathered from bottle feeding because more extensive research has been conducted on bottle feeding than on breastfeeding. However, …
