Abstract
BACKGROUND Preterm infants (< 37 weeks' post-menstrual age (PMA)) are often delayed in attaining oral feeding. Normal oral feeding is suggested as an important outcome for the timing of discharge from the hospital and can be an early indicator of neuromotor integrity and developmental outcomes. A range of oral stimulation interventions may help infants to develop sucking and oromotor co-ordination, promoting earlier oral feeding and earlier hospital discharge. This is an update of our 2016 review. OBJECTIVES To determine the effectiveness of oral stimulation interventions for attainment of oral feeding in preterm infants born before 37 weeks' PMA. SEARCH METHODS Searches were run in March 2022 of the following databases: CENTRAL via CRS Web; MEDLINE and Embase via Ovid. We also searched clinical trials databases and the reference lists of retrieved articles for randomised controlled trials (RCTs) and quasi-randomised trials. Searches were limited by date 2016 (the date of the search for the original review) forward. Note: Due to circumstances beyond our control (COVID and staffing shortages at the editorial base of Cochrane Neonatal), publication of this review, planned for mid 2021, was delayed. Thus, although searches were conducted in 2022 and results screened, potentially relevant studies found after September 2020 have been placed in the section, Awaiting Classification, and not incorporated into our analysis. SELECTION CRITERIA Randomised and quasi-randomised controlled trials comparing a defined oral stimulation intervention with no intervention, standard care, sham treatment or non-oral intervention (e.g. body stroking protocols or gavage adjustment protocols) in preterm infants and reporting at least one of the specified outcomes. DATA COLLECTION AND ANALYSIS Following the updated search, two review authors screened the titles and abstracts of studies and full-text copies when needed to identify trials for inclusion in the review. The primary outcomes of interest were time (days) to exclusive oral feeding, time (days) spent in NICU, total hospital stay (days), and duration (days) of parenteral nutrition. All review and support authors contributed to independent extraction of data and analysed assigned studies for risk of bias across the five domains of bias using the Cochrane Risk of Bias assessment tool. The GRADE system was used to rate the certainty of the evidence. Studies were divided into two groups for comparison: intervention versus standard care and intervention versus other non-oral or sham intervention. We performed meta-analysis using a fixed-effect model. MAIN RESULTS We included 28 RCTs (1831 participants). Most trials had methodological weaknesses, particularly in relation to allocation concealment and masking of study personnel. Oral stimulation compared with standard care Following meta-analysis, it is uncertain whether oral stimulation reduces the time to transition to oral feeding compared with standard care (mean difference (MD) -4.07 days, 95% confidence interval (CI) -4.81 to -3.32 days, 6 studies, 292 infants; I2 =85%, very low-certainty evidence due to serious risk of bias and inconsistency). Time (days) spent in the neonatal intensive care unit (NICU) was not reported. It is uncertain whether oral stimulation reduces the duration of hospitalisation (MD -4.33, 95% CI -5.97 to -2.68 days, 5 studies, 249 infants; i2 =68%, very low-certainty evidence due to serious risk of bias and inconsistency). Duration (days) of parenteral nutrition was not reported. Oral stimulation compared with non-oral intervention Following meta-analysis, it is uncertain whether oral stimulation reduces the time to transition to exclusive oral feeding compared with a non-oral intervention (MD -7.17, 95% CI -8.04 to -6.29 days, 10 studies, 574 infants; I2 =80%, very low-certainty evidence due to serious risk of bias, inconsistency and precision). Time (days) spent in the NICU was not reported. Oral stimulation may reduce the duration of hospitalisation (MD -6.15, 95% CI -8.63 to -3.66 days, 10 studies, 591 infants; I2 =0%, low-certainty evidence due to serious risk of bias). Oral stimulation may have little or no effect on the duration (days) of parenteral nutrition exposure (MD -2.85, 95% CI -6.13 to 0.42, 3 studies, 268 infants; very low-certainty evidence due to serious risk of bias, inconsistency and imprecision). AUTHORS' CONCLUSIONS There remains uncertainty about the effects of oral stimulation (versus either standard care or a non-oral intervention) on transition times to oral feeding, duration of intensive care stay, hospital stay, or exposure to parenteral nutrition for preterm infants. Although we identified 28 eligible trials in this review, only 18 provided data for meta-analyses. Methodological weaknesses, particularly in relation to allocation concealment and masking of study personnel and caregivers, inconsistency between trials in effect size estimates (heterogeneity), and imprecision of pooled estimates were the main reasons for assessing the evidence as low or very low certainty. More well-designed trials of oral stimulation interventions for preterm infants are warranted. Such trials should attempt to mask caregivers to treatment when possible, paying particular attention to blinding of outcome assessors. There are currently 32 ongoing trials. Outcome measures that reflect improvements in oral motor skill development as well as longer term outcome measures beyond six months of age need to be defined and used by researchers to capture the full impact of these interventions.

Abstract
BACKGROUND Oral support during feeding was clinically provided to patients with severe motor and intellectual disabilities (SMID) for the prevention of dysphasia. The present study investigated the advantages of oral support anatomically and functionally. METHODS A videofluoroscopic swallowing study was conducted on nine patients with SMID (age = 5-41 years; mean age = 15.0; four males, five females) and 24 healthy adults (age = 26-67 years; mean age = 44.3; 16 males, eight females). The movements of the hyoid bone and mandible during pharyngeal swallowing were tracked, and the pharyngeal residues were evaluated. The temporal and spatial features of the movements were compared between patients with and without oral support as well as healthy adults. RESULTS The mandible moved downward earlier and showed larger displacement in the patients with SMID. The patients also had insufficient anterior displacement of the hyoid, which was associated with the pharyngeal residue. This displacement was enhanced, and the pharyngeal residue decreased with oral support. CONCLUSIONS Oral support to hold the mandible successfully improved hyoid excursion and reduced pharyngeal residue during swallowing, which is a simple and reliable strategy for the prevention of dysphasia in patients with SMID.

Abstract
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.

Abstract
Purpose Pediatric feeding disorders (PFDs) present as a complex clinical challenge because of the heterogeneous underlying etiologies and their impact on health, safety, growth, and psychosocial development. A multidisciplinary team approach is essential for accurate diagnosis and prompt interventions to lessen the burdens associated with PFDs. The role of the speech-language pathologist (SLP) as a member of the multidisciplinary team will be highlighted. Method This clinical focus article reviews the definition of PFDs and pertinent literature on factors that contribute to the development of PFDs, the accurate diagnosis, and current interventions for infants and children. As part of the multidisciplinary team, the SLP has an integral role in determining whether a child cannot or will not eat and working with the team to identify and carryout appropriate interventions. Collaboration between SLPs and psychologists/behavioral specialists in conjunction with the parents/caregivers as part of the multidisciplinary team is essential to the advancement of therapeutic goals. Conclusions Due to their complex nature, the successful management of PFDs is only possible with the care and expertise of a multidisciplinary team, which includes parents/caregivers. SLPs are important members of these multidisciplinary teams and provide valuable input for the accurate identification and effective remediation of PFDs.

Abstract
BACKGROUND Premature birth is associated with feeding difficulties due to inadequate coordination of sucking, swallowing, and breathing. Nonnutritive sucking (NNS) and oral stimulation interventions may be effective for oral feeding promotion, but the mechanisms of the intervention effects need further clarifications. PURPOSE We reviewed preterm infant intervention studies with quantitative outcomes of sucking performance to summarize the evidence of the effect of interventions on specific components of sucking. METHODS PubMed, CINAHL, MEDLINE, EMBASE, and PSYCOLIST databases were searched for English language publications through August 2017. Studies were selected if they involved preterm infants, tested experimental interventions to improve sucking or oral feeding skills, and included outcome as an objective measure of sucking performance. Specific Medical Subject Headings (MeSH) terms were utilized. RESULTS Nineteen studies were included in this review: 15 randomized, 1 quasi-randomized, and 3 crossover randomized controlled trials. Intervention types were grouped into 6 categories (i) NNS, (ii) NNS with auditory reinforcement, (iii) sensorimotor stimulation, (iv) oral support, (v) combined training, and (vi) nutritive sucking. Efficiency parameters were positively influenced by most types of interventions, though appear to be less affected by trainings based on NNS alone. IMPLICATIONS FOR PRACTICE These findings may be useful in the clinical care of infants requiring support to achieve efficient sucking skills through NNS and oral stimulation interventions. IMPLICATIONS FOR RESEARCH Further studies including quantitative measures of sucking performance outcome measures are needed in order to best understand the needs and provide more tailored interventions to preterm infants.

A range of oral stimulation interventions may help infants to develop sucking and oromotor co-ordination, promoting earlier oral feeding and earlier hospital discharge. OBJECTIVES To determine the effectiveness of oral stimulation interventions for attainment of oral feeding in preterm infants born before 37 weeks' postmenstrual age (PMA).To conduct subgroup analyses for the following prespecified subgroups.• Extremely preterm infants born at < 28 weeks' PMA.• Very preterm infants born from 28 to < 32 weeks' PMA.• Infants breast-fed exclusively.• Infants bottle-fed exclusively.• Infants who were both breast-fed and bottle-fed. SEARCH METHODS We used the standard search strategy of the Cochrane Neonatal Review Group to search the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE via PubMed (1966 to 25 February 2016), Embase (1980 to 25 February 2016) and the Cumulative Index to Nursing and Allied Health Literature (CINAHL; 1982 to 25 February 2016). We searched clinical trials databases, conference proceedings and the reference lists of retrieved articles. SELECTION CRITERIA Randomised and quasi-randomised controlled trials comparing a defined oral stimulation intervention with no intervention, standard care, sham treatment or non-oral intervention in preterm infants and reporting at least one of the specified outcomes. DATA COLLECTION AND ANALYSIS One review author searched the databases and identified studies for screening. Two review authors screened the abstracts of these studies and full-text copies when needed to identify trials for inclusion in the review. All review authors independently extracted the data and analysed each study for risk of bias across the five domains of bias. All review authors discussed and analysed the data and used the GRADE system to rate the quality of the evidence. Review authors divided studies into two groups for comparison: intervention versus standard care and intervention versus other non-oral or sham intervention. We performed meta-analysis using a fixed-effect model. MAIN RESULTS This review included 19 randomised trials with a total of 823 participants. Almost all included trials had several methodological weaknesses. Meta-analysis showed that oral stimulation reduced the time to transition to oral feeding compared with standard care (mean difference (MD) -4.81, 95% confidence interval (CI) -5.56 to -4.06 days) and compared with another non-oral intervention (MD -9.01, 95% CI -10.30 to -7.71 days), as well as the duration of initial hospitalisation compared with standard care (MD -5.26, 95% CI -7.34 to -3.19 days) and compared with another non-oral intervention (MD -9.01, 95% CI -10.30 to -7.71 days).Investigators reported shorter duration of parenteral nutrition for infants compared with standard care (MD -5.30, 95% CI -9.73 to -0.87 days) and compared with another non-oral intervention (MD -8.70, 95% CI -15.46 to -1.94 days). They could identify no effect on breast-feeding outcomes nor on weight gain. AUTHORS' CONCLUSIONS Although the included studies suggest that oral stimulation shortens hospital stay, days to exclusive oral feeding and duration of parenteral nutrition, one must interpret results of these studies with caution, as risk of bias and poor methodological quality are high overall. Well-designed trials of oral stimulation interventions for preterm infants are warranted. Such trials should use reliable methods of randomisation while concealing treatment allocation, blinding caregivers to treatment when possible and paying particular attention to blinding of outcome assessors.

IRANIAN RED CRESCENT MEDICAL JOURNAL 2015; 17:e13515. [PMID: 26421163 PMCID: PMC4583832 DOI: 10.5812/ircmj.17(5)2015.13515] [Citation(s) in RCA: 13] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 07/16/2013] [Revised: 09/07/2014] [Accepted: 03/20/2015] [Indexed: 11/22/2022]
Abstract
Background: One of the limiting factors for early hospital discharge in preterm infants is their inability to feed sufficiently to obtain consistent weight gain. Therefore, feeding difficulty is one of the most significant issues with which a preterm infant is faced. Objectives: The purpose of this study was to examine the effect of oral sensory motor stimulation on feeding performance, length of hospital stay, and weight gain in preterm infants at 30 - 32 weeks of gestational age. Patients and Methods: Premature infants (n = 20) were randomly assigned to experimental and control groups. The experimental group received oral sensory motor stimulation of the oral structures (15 minutes / day) for 10 successive days, while these stimulations were not offered to the control group. Days elapsed to achieve oral feeding, length of hospital stay, and weight gain in the two groups were assessed. Results: Transition to oral feeding was acquired significantly earlier in the infants in the experimental group than in the controls: 13 and 26 days, respectively (P < 0.001). Likewise, the length of hospitalization was significantly shorter in the experimental group than in the control group: 32 days and 38 days, correspondingly (P < 0.05). The two groups showed no significant difference in terms of weight gain in the first, second, third, and fourth weeks of birth: first week: 100 vs. 110; second week: 99 vs. 111; third week: 120 vs. 135; and fourth week: 129 vs. 140. Conclusions: The present research revealed that the number of days to reach oral feeding in our preterm babies was decreased by oral motor stimulation, which in turn conferred earlier hospital discharge.

Abstract
Precise assessment of infants’ ability to regulate feeding challenges requires modeling of physiologic values across intervals of the feeding period without smoothing too much of the data stream. Using a subset of data from a study of physiologic stability and feeding performance in very preterm (≤30 weeks’ gestational age) infants fed in two different feeding positions, this exploratory study compared mean heart rate (HR) and its coefficient of variation sampled during the feeding period using four methods: (1) dividing the feeding period into three equal intervals; (2) extracting 2-min intervals from the initial, middle, and final third of the feeding period; (3) using successive 2-min intervals during the first 6 min of feeding; and (4) using successive 2-min intervals during the entire feeding period. Power analysis simulation was conducted with varying numbers of subjects to determine the method that requires the least number of subjects to detect a position effect for change in HR across time with 80% power. Different patterns of HR change across the feeding period were observed across the methods, which suggest potential advantages and disadvantages of each method. Among the four methods, using the first 6 min of the feeding period required the fewest subjects to detect significant differences in changes in HR across time between the feeding positions.

Abstract
The purpose of this article was to present the case of a premature infant who displayed immature feeding progression because of nasal occlusion. Two male preterm infants of 33 weeks' gestational age at birth from a larger randomized trial were observed in a comparative case study. Using a prospective design, feeding assessments were conducted weekly from initiation of oral feeding until hospital discharge. Sucking organization was measured using the Medoff-Cooper Nutritive Sucking Apparatus (M-CNSA), which measured negative sucking pressure generated during oral feedings. Oral and nasogastric (NG) intake and vital signs were recorded. At 35 weeks, infant A demonstrated an immature feeding pattern with the M-CNSA NG feedings prevailing over oral feedings. When attempting to feed orally, infant A exhibited labored breathing and an erratic sucking pattern. During the third weekly feeding evaluation, nasal occlusion was discovered, the NG tube was discontinued, and phenylephrine (Neo-Synephrine) and humidified air were administered. Following treatment, infant A's sucking pattern normalized and the infant maintained complete oral feeding. Infant B demonstrated normal feeding progression. Nasal occlusion prevented infant A from achieving successful oral feeding. The M-CNSA has the ability to help clinicians detect inconsistencies in the sucking patterns of infants and objectively measures patterns of nutritive sucking. The M-CNSA has the potential to influence clinical decision making and identify the need for intervention.

Abstract
This article presents the elements of the Oral Motor Intervention section of the Infant Care Path for Physical Therapy in the Neonatal Intensive Care Unit (NICU). The types of physical therapy interventions presented in this path are evidence based as well as infant driven and family focused. In the context of anticipated maturation of suck-swallow-breathe coordination, the timing and methods for initiation of oral feedings and transition from gavage to full breast or bottle-feedings are presented with supporting evidence.

Abstract
Preterm infants often display difficulty establishing oral feeding in the weeks following birth. This article aims to provide an overview of the literature investigating the development of feeding skills in preterm infants, as well as of interventions aimed at assisting preterm infants to develop their feeding skills. Available research suggests that preterm infants born at a lower gestational age and/or with a greater degree of morbidity are most at risk of early feeding difficulties. Respiratory disease was identified as a particular risk factor. Mechanisms for feeding difficulty identified in the literature include immature or dysfunctional sucking skills and poor suck–swallow–breath coordination. Available evidence provides some support for therapy interventions aimed at improving feeding skills, as well as the use of restricted milk flow to assist with maintaining appropriate ventilation during feeds. Further research is needed to confirm these findings, as well as to answer remaining clinical questions.

Abstract
Abstract
OBJECTIVE. We examined the effects of cheek and jaw support on the feeding ability of inefficient feeders born prematurely.
METHOD. Twenty preterm infants served as their own controls. Each infant received either intervention (feeding with oral support) or control (feeding without oral support) for 2 consecutive feedings per day on 2 consecutive days.
RESULTS. Infants displayed a greater intake rate during the intervention feedings, both during the first 5 min (p = .046) and throughout the entire feeding (p = .023). The percentage of leakage during the first 5-min feeding was smaller in the intervention condition than in the control condition (p = .040). No significant differences were found between the two conditions in the sucking, physiological, and alertness variables.
CONCLUSION. Findings confirm oral support as a safe and effective strategy to improve the feeding performance of preterm infants who are poor feeders.

Abstract
Prolonged use of gavage feedings is common in premature infants who have not yet acquired suck, swallow, and breathing coordination. Preterm infants must be developmentally mature to orally feed successfully. Als' Synactive Theory of Development offers a conceptual framework to facilitate understanding of how premature infants dynamically differentiate to attain developmental milestones such as oral feeding. Key clinical implications for neonatal nurses are contingent upon incorporating evidence-based research into practice and providing consistent quality care to improve feeding outcomes.

Abstract
AIM To study the effect of stimulation of sucking and swallowing on weaning from nasogastric (NG) feeding and length of hospital stay in premature infants. METHOD Randomized controlled trial with blinded evaluation. Premature infants on NG feeds and post-menstrual age (PMA) less than 36 weeks who had poor ability to suck were randomized to receive one daily session of stimulation according to Vojta or no intervention other than standard nursing care. RESULTS Of 36 infants, 18 received stimulation and 18 were observed without intervention. Mean gestational age at birth was 32.2 weeks (SD 2.4) versus 31.4 (2.3) weeks, p = 0.27, and PMA at study entry 35.1 weeks (0.8) versus 34.4 (0.9) weeks, p = 0.01, respectively. NG feeding was discontinued at 36.8 weeks (0.9) versus 36.3 (0.9) weeks' PMA, p = 0.25, and they were discharged at 37.8 weeks (0.9) versus 37.7 (1.3) weeks, p = 0.81. CONCLUSION The stimulation programme did not result in earlier weaning from NG feeding or earlier discharge. However, such studies may need to be large to limit the possibility of type II errors.

Abstract
This study compared the effects of oral stimulation with those of oral support on non-nutritive sucking and feeding parameters in preterm infants. Preterm infants (23 males, 20 females) born between 29 and less than 34 weeks' gestational age (GA; mean GA 31.2wks [standard error of mean{SEM} 0.39]; mean birth-weight 1580g [SEM 120]) were allocated to one of three experimental groups: (Stimulation+support [five males, four females]; Stimulation [four males, seven females]; and Support [seven males, five females]) or a control group. Non-nutritive sucking pressure and sucking activity were quantified in the gavage and transition periods. Oral support minimizes fluid loss, stabilizes the jaw, and organizes deglutition. The time of transition, the quantity of milk ingested per day, and the number of bottle feeds per day were recorded. Variables were analyzed by repeated-measures analysis of variance, with birth-weight as covariate (ANCOVA). Transition time was reduced (p<0.0001) for the Stimulation+support and Support groups. ANCOVA computed during gavage showed increased non-nutritive sucking pressure and sucking activity (p<0.001) for the Stimulation and Stimulation+support groups. ANCOVA computed during transition revealed increases in non-nutritive sucking pressure and daily bottle feeds (p<0.001) for the three experimental groups and in daily milk ingested (p=0.002) for the Stimulation+support and Support groups. We demonstrated that oral support is the result of both the action of chin and cheek support, and the aid to deglutition. An analysis of the organization of sucking patterns should be undertaken to provide better understanding of the mechanisms involved in oral support.

Abstract
OBJECTIVE This study examined the relationship between the number of sucks in the first nutritive suck burst and feeding outcomes in preterm infants. The relationships of morbidity, maturity, and feeding experience to the number of sucks in the first suck burst were also examined. METHODS A non-experimental study of 95 preterm infants was used. Feeding outcomes included proficiency (percent consumed in first 5 min of feeding), efficiency (volume consumed over total feeding time), consumed (percent consumed over total feeding), and feeding success (proficiency >or=0.3, efficiency >or=1.5 mL/min, and consumed >or=0.8). Data were analyzed using correlation and regression analysis. RESULTS AND CONCLUSIONS There were statistically significant positive relationships between number of sucks in the first burst and all feeding outcomes-proficiency, efficiency, consumed, and success (r=0.303, 0.365, 0.259, and tau=0.229, P<.01, respectively). The number of sucks in the first burst was also positively correlated to behavior state and feeding experience (tau=0.104 and r=0.220, P<.01, respectively). Feeding experience was the best predictor of feeding outcomes; the number of sucks in the first suck burst also contributed significantly to all feeding outcomes. The findings suggest that as infants gain experience at feeding, the first suck burst could be a useful indicator for how successful a particular feeding might be.

Abstract
Preterm infants develop the skills necessary to begin oral feeding as their health stabilizes and as they reach a postconceptional age that supports coordination of breathing and swallowing with oral-motor functioning. The time from initiation of oral feeding to full oral feedings (with adequate intake for growth and maintenance of physiologic stability) can vary from days to months for the preterm infant. The approach to feeding the infant during this transition period must be developmentally supportive and tailored to meet the needs of the individual. To accomplish this, caregivers--notably nurses and parents--need to communicate about the specific skills that the infant has gained, about skills that are emerging, and about skills that the infant has not yet developed. The Early Feeding Skills (EFS) Assessment is a checklist for assessing infant readiness for and tolerance of feeding and for profiling the infant's developmental stage regarding specific feeding skills: the abilities to remain engaged in feeding, organize oral-motor functioning, coordinate swallowing with breathing, and maintain physiologic stability. This article introduces the EFS.

Abstract
Finding ways to consistently prepare preterm infants and their families for more timely discharge must continue as a focus for everyone involved in the care of these infants in the neonatal intensive care unit. The gold standards for discharge from the neonatal intensive care unit are physiologic stability (especially respiratory stability), consistent weight gain, and successful oral feeding, usually from a bottle. Successful bottle-feeding is considered the most complex task of infancy. Fostering successful oral feeding in preterm infants requires consistently high levels of skilled nursing care, which must begin with accurate assessment of feeding readiness and thoughtful progression to full oral feeding. This comprehensive review of the literature provides an overview of the state of the science related to feeding readiness and progression in the preterm infant. The theoretical foundation for feeding readiness and factors that appear to affect bottle-feeding readiness, progression, and success are presented in this article.

Abstract
BACKGROUND Preterm infants have difficulty maintaining engagement throughout early oral feedings, which can lead to less efficient feeding and prolonged feeding skill development. OBJECTIVE To examine contributions of the infant, mother, and feeding context to infant engagement during bottle-feeding. METHODS Bottle-feedings of very-low-birthweight infants (n = 22) by their mothers were observed. Infant and maternal behaviors were coded and synchronized with physiologic measures. At completion of the feeding, the mothers were interviewed, and their working model of feeding coregulation was scored. Feedings were subdivided into feeding episodes (n = 114). Using multilevel linear regression analyses, four dyadic characteristics (working model of the caregiver's role as coregulator, birthweight, postconceptional age, baseline oxygen saturation) and five episode characteristics (readiness at episode onset, episode baseline oxygen saturation, mean oxygen saturation during the episode, maternal feeding behavior, and phase of feeding) were examined as potential predictors of feeding episode engagement. RESULTS Conditions observed during the feeding observation explained most of the variation in engagement. Engagement was more likely to occur during the early phase of feeding (p <.05), during feeding episodes that began with infant readiness (p <.05), and during feeding episodes with higher mean oxygen saturation during the episode (p <.05). Feeding episodes with less jiggling of the nipple had a significantly greater amount of engagement (p <.05). CONCLUSIONS The ability of the preterm infant to maintain engagement during bottle-feeding cannot be explained by characteristics of the infant or by the prefeeding condition of the infant alone. Rather, engagement is coregulated by the caregiver and the infant throughout the feeding. Strategies to assist infants in maintaining physiologic stability during bottle-feeding and further study of effective and contingent caregiver feeding behaviors are needed.

Abstract
PURPOSE The purpose of this study was to examine the effect of prefeeding non-nutritive sucking (NNS) on breathing, nutritive sucking (NS), and behavioral characteristics of bottle feeding. SUBJECTS The convenience sample was composed of 10 preterm infants who were 33 to 40 weeks postconceptual age (PCA) at the time of the observation. DESIGN Randomized, crossover; each infant was observed twice during the first 48 hours of bottle feeding. METHODS Ten preterm infants received NNS before 1 bottle feeding and served as their own control at a second bottle feeding. Sucking was measured using a chin strain gauge and breathing was measured with a nasal thermistor. Behavioral characteristics included behavior state, measured using the Neonatal Individualized Developmental Care and Assessment Program (NIDCAP) behavior state scale, and feeding efficiency. MAIN OUTCOME MEASURES Characteristics of NS (number of suck bursts, sucks/burst, suck burst length) and breathing (number of breath bursts, breaths/burst, breath burst length), as well as behavior state during bottle feedings and feeding efficiency (percent of prescribed formula consumed, formula consumed/minute of feeding). PRINCIPAL RESULTS NS waves were smoother and more regular than NNS waves. Time to onset and duration of the first non-nutritive suck burst were positively correlated with time to onset for the first nutritive suck burst. Prefeeding NNS had no statistically significant effect on characteristics of breathing or on any other characteristics of NS. Behavioral state during feedings and feeding efficiency were not affected by prefeeding NNS. CONCLUSIONS In this sample, the use of prefeeding NNS did not affect NS, breathing during feeding, or select behavioral characteristics of feeding.

Abstract
BACKGROUND For preterm infants and infants who have difficulty with oral feeding, excessive drooling during oral feedings can result in inaccurate assessment of intake. The drooled volume is typically estimated by visual and tactile assessment of the bib. Research, however, has demonstrated that visual assessment is inaccurate. PURPOSE The purpose of this study was to determine the accuracy of a scale that was used for the test weighing of milk that was drooled during a study of oral feeding for preterm infants. Additionally, the effect of weighing solutions with different densities on the accuracy of test weights was examined. METHOD Descriptive, comparative design. PROCEDURES A simulated feeding situation was performed using 3 fluids (water, Enfamil(20), and Enfamil(24)) and 3 volume ranges (1 mL to 10 mL, 11 mL to 20 mL, and 21 mL to 30 mL). Data collection sessions were conducted for each of the 3 fluids using each range of volumes, for a total of 180 test weights. The research assistant performing the test weights was blinded to the preweight of the bib and the amount of fluid being applied to the bib. RESULTS Differences between the actual volume applied to the bib and the volume estimated by the scale were very small, with 51% of the differences equaling 0 mL and 48% of the differences between -1 mL and 1 mL. There were significant differences in errors related to both the type of fluid (F = 25.7; df = 2; P < 0.001) and volume range (F = 12.7; df = 2; P < 0.001), as well as for the interaction between the 2 factors (F = 7.02; df = 4; P < 0.001). Water had significantly less mean error than either formula, and large volumes had significantly greater mean error than either small or medium volumes. CONCLUSIONS Test weighing is an accurate method for measuring fluids of different densities and volumes in a simulation of drooling during oral feeding. The increased error with larger volumes of higher density solutions was not clinically significant. The study supports the need to consider both the accuracy of the scale and characteristics of the fluid when test weighing is used to measure volumes of fluids.

Abstract
BACKGROUND During the time when preterm infants' oral feeding skills are developing they often experience physiological instability and need assistance from caregivers to maintain adequate oxygenation. Assisting infants to maintain optimal oxygenation during oral feeding requires an understanding of how they express and aim to self-regulate their oxygen status. AIM The purpose of this study was to identify potential behavioural indicators of declining oxygenation during preterm infant early bottle-feeding. METHOD The design was explorative. Data were collected from a secondary analysis of 20 videotapes of preterm infant bottle feedings which included concurrent oxygen saturation data. In this analysis infant behaviours and quality of breathing were coded and compared across three periods: high oxygen saturation, immediately preceding an oxygen desaturation event, and during an oxygen desaturation event. FINDINGS Infants gave limited behavioural indicators of declining oxygenation. Immediately prior to a desaturation event, they had an increase in eye flutter and were typically sucking and apnoeic. During a desaturation event, they typically relaxed their arms/hands and stopped sucking. CONCLUSIONS Reliance on preterm infant behavioural cues will be insufficient for detection of oxygen desaturation during oral feeding. Attention to changes in breath sounds and to the pattern of sucking are potentially important intervention strategies for the prevention of and appropriate response to oxygen decline during feeding. Sucking pauses may be a time when preterm infants aim to regulate their breathing pattern and thereby increase oxygenation. Interventions that focus on detection and minimization of apnoea during feeding, and which aim to protect infant sucking pauses, may reduce the number and severity of desaturation events preterm infants experience during bottle feeding.

Abstract
The ability of a preterm infant to make the transition from gavage to oral nipple feeding depends on the infant's neurodevelopment in relation to behavioral organization, to a rhythmic suck-swallow-breathe pattern, and to cardiorespiratory regulation. Research-based knowledge about infant neurodevelopment in these three areas has led to the creation of a semidemand feeding method to aid in this transition. The method combines the use of nonnutritive sucking to promote awake behavior for feeding, use of behavioral assessment to identify readiness for feeding, and systematic observation of and response to infant behavior cues to regulate frequency, length, and volume of oral feedings. Semidemand feeding may be individualized for healthy preterm infants. This article discusses both the relevant knowledge about neurodevelopment and the semidemand feeding method itself.

Abstract
OBJECTIVE To ascertain whether the implementation of a paced feeding protocol in a sample of preterm infants with respiratory diagnoses will result in the development of more efficient sucking patterns, increased weight gain, decreased incidence of bradycardia during feeding, and shorter length of hospital stay. METHOD A total of 36 premature infants were enrolled into a nonrandomized clinical trial conducted in a neonatal intensive care unit (NICU). The first 18 infants were traditionally bottle-fed. Following this cohort's discharge from NICU, nursing staff completed continuing education on implementing a paced feeding protocol and the next 18 infants were delivered paced feedings. RESULTS The two cohorts were equivalent at the initiation of oral feedings on gestational age, birth weight, 1 and 5 minute Apgar scores, weight, and postconceptual age. The paced infants demonstrated statistically and clinically significant decreases in bradycardic incidences during feeding and gains in development of more efficient sucking patterns at discharge. Discharge and average weekly weight gain did not differ between the two groups. CONCLUSIONS The incorporation of pacing into NICU care practices appears to be beneficial for preterm infants with respiratory disease.
