Abstract
Objective To explore the relationship between different modes of respiratory support and feeding intolerance (FI) in preterm infants over the course of their hospitalization and to provide recommendations for the management of enteral feeding in preterm infants requiring respiratory support. Methods A retrospective analysis was performed with the preterm infants admitted to the Neonatal Intensive Care Unit (NICU), West China Second University Hospital, Sichuan University between June 2015 and November 2018. The modes of respiratory support were used as independent variables and FI was used as the outcome indicator. The preterm infants were grouped according to the specific modes of respiratory support they were on over the course of their hospitalization and the relationship between each mode of respiratory support and FI was compared. Results A total of 272 preterm infants were enrolled in the study. After adjusting for confounding factors, findings from logistics regression suggested that, compared with normobaric oxygen, high flow nasal cannula (HFNC) might reduce the incidence of FI (odds ratio [OR]=0.53, 95% confidence interval [CI]: 0.06-4.77), while other modes of respiratory support might increase the incidence of FI. Compared with nasal continuous positive airway pressure (NCPAP), bilevel positive airway pressure (BIPAP) and invasive ventilation might increase the incidence of FI, with the adjusted OR being 1.31 and 1.69, and 95% CI being 0.67-2.55 and 0.65-4.41, respectively. The incidence of FI in BIPAP and invasive ventilation was similar (adjusted OR=1.00, 95% CI: 0.41-2.42). However, the P-values of the above results were all greater than 0.05. Conclusion HFNC has the lowest incidence of FI in the respiratory support modes examined in this study. Attention should be paid to enteral feeding management when using NCPAP, BIPAP, and invasive ventilation to avoid the occurrence of FI. Given the limited sample size, further research is warranted to confirm the conclusion.

Abstract
Nasal continuous positive airway pressure (nCPAP) is a safe, effective, non-invasive respiratory modality to deliver positive end expiratory pressure in neonates. Many studies have established its associated improved respiratory outcomes without increase in major morbidities associated with preterm neonates. In contrast, there is paucity in literature addressing complications such as nasal injury, abdominal distention, air leak syndromes (especially pneumothorax), hearing loss, heat and chemical burns, swallowing and aspiration of small components of the nasal interface and delay in escalation of respiratory support associated with the use of nCPAP, most frequently due to its incorrect use. This is a comprehensive review that seeks to address the different complications that are associated with the incorrect use of nCPAP highlighting that these are operator-related and not device-related.

Early-Life Slow Enteral Feeding Progression Pattern Is Associated with Longitudinal Head-Size Growth Faltering and Neurodevelopmental Impairment Outcomes in Extremely Preterm Infants. Nutrients 2023; 15:nu15051277. [PMID: 36904276 PMCID: PMC10005088 DOI: 10.3390/nu15051277] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/04/2023] [Revised: 03/02/2023] [Accepted: 03/02/2023] [Indexed: 03/08/2023] Open
Abstract
OBJECTIVE To determine whether feeding progression patterns in the first eight postnatal weeks, depicted by clustering analysis of daily enteral feeding volume, are associated with longitudinal head-circumference (HC) growth and neurodevelopmental outcomes in extremely preterm (EP) infants. METHODS 200 infants who were admitted at gestational ages 23-27 weeks between 2011 and 2018; survived to discharge; and underwent longitudinal HC growth measurements at birth, term-equivalent age (TEA), corrected age (CA) 6-month, 12-month, and 24-month; and neurodevelopmental assessment using the Bayley Scales of Infant Development at CA 24 months were included for analysis. RESULTS kmlShape analysis identified two distinct enteral feeding progression patterns: fast progression in 131 (66%) infants and slow progression in 69 (34%) infants. Compared to the fast progression group, the slow progression group showed significantly lower daily enteral volumes after day 13, was older in postnatal age reaching full feeding, had a higher rate of Delta z scores of HC (zHC) < -1 (p < 0.001) between birth and TEA, and displayed lower longitudinal zHC from TEA to CA 24 months. The slow progression group also showed higher rates of microcephaly [42% vs. 16%, p < 0.001; adjusted odd ratio (aOR): 3.269, p = 0.001] and neurodevelopmental impairment (NDI) (38% vs. 19%, p = 0.007; aOR: 2.095, p = 0.035) at CA 24 months. For NDI, the model including feeding progression patterns showed a lower Akaike information criterion score and a better goodness of fit than the model that did not include feeding patterns. CONCLUSION Characterizing feeding progression pattern may help identify EP infants at high-risk of head-size growth faltering and NDI at early childhood.

Abstract
PURPOSE High-Flow Nasal Cannula (HFNC) has become an increasingly common means of noninvasive respiratory support in pediatrics and is being used in infants and children with respiratory distress both inside and outside of the intensive care units. Despite the widespread use of HFNC, there remains a paucity of data on optimal flow rates and its impact on morbidity, mortality, and desired outcomes. Given the scarcity of information in these critical areas, it is not surprising that guidelines for initiation of oral feeding do not exist. This review article will review HFNC mechanisms of action, its use in specific populations and settings, and finally what is known about initiation of feeding during this therapy. CONCLUSIONS The practice of withholding oral feeding solely, because of HFNC, is not supported in the literature at the time of this writing, but in the absence of safety data from clinical trials, clinicians should proceed with caution and consider patient-specific factors while making decisions about oral feeding. Well-controlled prospective clinical trials are needed for development of best practice clinical guidelines and attainment of optimal outcomes.

Nutrients 2022; 14:nu14051032. [PMID: 35268013 PMCID: PMC8912445 DOI: 10.3390/nu14051032] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/27/2021] [Revised: 02/25/2022] [Accepted: 02/28/2022] [Indexed: 11/16/2022] Open
Abstract
Establishing the different feeding trajectories based on daily enteral feeding data in preterm infants at different gestational ages (GAs), may help to identify the risks and extrauterine growth restriction (EUGR) outcomes associated with the adverse feeding pattern. In a single center, we retrospectively included 625 infants born at 23-30 weeks of gestation who survived to term-equivalent age (TEA) from 2009 to 2020. The infants were designated into three GA groups: 23-26, 27-28, and 29-30 weeks. The daily enteral feeding amounts in the first 56 postnatal days were analyzed to determine the feeding trajectories. The primary outcomes were EUGR in body weight and head circumference calculated, respectively, by the changes between birth and TEA. Clustering analysis identified two feeding trajectories, namely the improving and adverse patterns in each GA group. The adverse feeding pattern that occurred in 49%, 20%, and 17% of GA 23-26, 27-28, and 29-30 weeks, respectively, was differentiated from the improving feeding pattern as early as day 7 in infants at GA 23-26 and 27-28 weeks, in contrast to day 21 in infants at GA 29-30 weeks. The adverse feeding patterns were associated with sepsis, respiratory, and gastrointestinal morbidities at GA 23-26 weeks; sepsis, hemodynamic and gastrointestinal morbidities at GA 27-28 weeks; and preeclampsia, respiratory, and gastrointestinal morbidities at GA 29-30 weeks. Using the improving feeding group as a reference, the adverse feeding group showed significantly higher adjusted odds ratios of EUGR in body weight and head circumference in infants at GA 23-26 and 27-28 weeks. Identifying the early-life adverse feeding trajectories may help recognize the related EUGR outcomes of preterm infants in a GA-related manner.

[PMID: 35046837 PMCID: PMC8762202 DOI: 10.3389/fphys.2021.785086] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/28/2021] [Accepted: 12/06/2021] [Indexed: 11/19/2022] Open
Abstract
Aim: Convalescing preterm infants often require non-invasive respiratory support, such as nasal continuous positive airway pressure or high-flow nasal cannulas. One challenging milestone for preterm infants is achieving full oral feeding. Some teams fear nasal respiratory support might disrupt sucking–swallowing–breathing coordination and induce severe cardiorespiratory events. The main objective of this study was to assess the safety of oral feeding of preterm lambs on nasal respiratory support, with or without tachypnoea. Methods: Sucking, swallowing and breathing functions, as well as electrocardiogram, oxygen haemoglobin saturation, arterial blood gases and videofluoroscopic swallowing study were recorded in 15 preterm lambs during bottle-feeding. Four randomly ordered conditions were studied: control, nasal continuous positive airway pressure (6 cmH2O), high-flow nasal cannulas (7 L•min–1), and high-flow nasal cannulas at 7 L•min–1 at a tracheal pressure of 6 cmH2O. The recordings were repeated on days 7–8 and 13–14 to assess the effect of maturation. Results: None of the respiratory support impaired the safety or efficiency of oral feeding, even with tachypnoea. No respiratory support systematically impacted sucking–swallowing–breathing coordination, with or without tachypnoea. No effect of maturation was found. Conclusion: This translational physiology study, uniquely conducted in a relevant animal model of preterm infant with respiratory impairment, shows that nasal respiratory support does not impact the safety or efficiency of bottle-feeding or sucking–swallowing–breathing coordination. These results suggest that clinical studies on bottle-feeding in preterm infants under nasal continuous positive airway pressure and/or high-flow nasal cannulas can be safely undertaken.

Abstract
OBJECTIVE To assess the eligibility criteria and trial characteristics among contemporary (2010-2019) randomized clinical trials (RCTs) that included infants born extremely preterm (<28 weeks of gestation) and to evaluate whether eligibility criteria result in underrepresentation of high-risk subgroups (eg, infants born at <24 weeks of gestation). STUDY DESIGN PubMed and Scopus were searched January 1, 2010, to December 31, 2019, with no language restrictions. RCTs with mean or median gestational ages at birth of <28 weeks of gestation were included. The study followed the PRISMA guidelines; outcomes were registered prospectively. Data extraction was performed independently by multiple observers. Study quality was evaluated using a modified Jadad scale. RESULTS Among RCTs (n = 201), 32 552 infants were included. Study participant characteristics, interventions, and outcomes were highly variable. A total of 1603 eligibility criteria were identified; rationales were provided for 18.8% (n = 301) of criteria. Fifty-five RCTs (27.4%) included infants <24 weeks of gestation; 454 (1.4%) infants were identified as <24 weeks of gestation. CONCLUSIONS The present study identifies sources of variability across RCTs that included infants born extremely preterm and reinforces the critical need for consistent and transparent policies governing eligibility criteria.

Abstract
Newborn infants with respiratory difficulties frequently require nasal respiratory support such as nasal continuous positive airway pressure (nCPAP) or high-flow nasal cannulae (HFNC). Oral feeding of these infants under nasal respiratory support remains controversial out of fear of aspiration and cardiorespiratory events. The main objective of this study was to evaluate the safety of oral feeding under different types of nasal respiratory support in newborn lambs without or with tachypnea. Eight lambs aged 4-5 days were instrumented to record sucking, swallowing, respiration, ECG, oxygen saturation, and arterial blood gases. Each lamb was given two bottles of 30 mL of milk with a pause of 30 s under videofluoroscopy in four conditions [no respiratory support, nCPAP 6 cmH2O, HFNC 7 L/min, HFNCCPAP (= HFNC 7 L/min + CPAP 6 cmH2O)] administered in random order. The study was conducted in random order over 2 days, with or without standardized tachypnea induced by thoracic compression with a blood pressure cuff. Generalized linear mixed models were used to compare the four nasal respiratory supports in terms of safety (cardiorespiratory events and aspiration), sucking-swallowing-breathing coordination, and efficacy of oral feeding. Results reveal that no nasal respiratory support impaired the safety of oral feeding. Most of the few laryngeal penetrations we observed occurred with HFNCCPAP. Nasal CPAP modified sucking-swallowing-breathing coordination, whereas the efficiency of oral feeding decreased under HFNCCPAP. Results were similar with or without tachypnea. In conclusion, oral feeding under nasal respiratory support is generally safe in a term lamb, even with tachypnea.NEW & NOTEWORTHY The practice of orally feeding newborns suffering from respiratory problems while on nCPAP or HFNC remains controversial for fear of triggering cardiorespiratory events or aspiration pneumonia, or aggravating chronic lung disease. The present results show that bottle-feeding is generally safe in full-term lambs under nasal respiratory support, both without and with tachypnea.

Abstract
BACKGROUND The aim of this systematic review was to determine whether introduction of oral feeding for infants and children receiving nasal continuous positive airway pressure (nCPAP) or high flow nasal cannula (HFNC) respiratory support facilitates achievement of full oral feeding without adverse effects, compared to no oral feeding (NPO; nil per oral) on CPAP or HFNC. METHODS A protocol was lodged with the PROSPERO International Prospective Register of Systematic Reviews. We searched Medline, Embase, CINAHL, CENTRAL and AustHealth from database inception to 10th June 2020. Study population included children (preterm to < 18 years) on nCPAP or HFNC who were orally feeding. Primary outcomes included full or partial oral feeding and oropharyngeal aspiration. Secondary outcomes examined adverse events including clinical signs of aspiration, aspiration pneumonia and deterioration in respiratory status. RESULTS The search retrieved 1684 studies following duplicate removal. Title and abstract screening identified 70 studies for full text screening and of these, 16 were included in the review for data extraction. Methods of non-invasive ventilation (NIV) included nCPAP (n = 6), nCPAP and HFNC (n = 5) and HFNC (n = 5). A metanalysis was not possible as respiratory modes and cohorts were not comparable. Eleven studies reported on adverse events. Oral feeding safety was predominantly based on retrospective data from chart entries and clinical signs, with only one study using an instrumental swallow evaluation (VFSS) to determine aspiration status. CONCLUSIONS Findings are insufficient to conclude whether commencing oral feeding whilst on nCPAP or HFNC facilitates transition to full oral feeding without adverse effects, including oropharyngeal aspiration. Further research is required to determine the safety and efficacy of oral feeding on CPAP and HFNC for infants and children. TRIAL REGISTRATION PROSPERO registration number: CRD42016039325 .

[PMID: 33288867 DOI: 10.1038/s41372-020-00887-6] [Citation(s) in RCA: 12] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/21/2020] [Revised: 10/14/2020] [Accepted: 11/20/2020] [Indexed: 01/02/2023]
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
OBJECTIVE We compared protocolized weaning versus nonprotocolized weaning practice from nasal high flow therapy (nHFT) in preterm infants. STUDY DESIGN A before-and- after observational study. METHODS The study was conducted in three phases; Phase 1: infants were weaned according to usual practice for 6 months (nonprotocolized), Phase 2: education and training physicians and nursing staff for the protocol for 1 month, and Phase 3: protocol of weaning from nHFT was applied for the following 6 months with specified criteria for readiness to wean, weaning failure and weaning technique. The primary outcome was failure to wean off nHFT. RESULTS One hundred and four preterm infants were enrolled, 51 preterm infants in the protocol group and 53 in the nonprotocol group. The groups were similar in demographic and clinical characteristics at baseline. There were significantly lower number of patients who failed weaning from nHFT in the protocol group compared to nonprotocol group (4 [7.8%] versus 15 [28.3%], p = .007]. There was shorter time to reach full enteral feeding in the protocol group compared with nonprotocol group (p = .03). There were no significant differences between groups regarding other outcomes including total durations of respiratory support, nHFT and oxygen therapy, duration of nHFT after decision of weaning, and neonatal mortality and morbidity. CONCLUSION Implementation of a standardized protocol for weaning from nHFT in preterm infants reduced weaning failure and reduced the time to full feeds. Larger trials are recommended to detect the impact of weaning protocols on other outcomes.

Abstract
OBJECTIVE To systematically evaluate the efficacy and safety of high-flow nasal cannula (HFNC) therapy versus nasal continuous positive airway pressure (nCPAP) in the treatment of respiratory distress syndrome (RDS) in neonates. METHODS PubMed, Embase, Cochrane Library, Web of Science, China Biology Medicine disc, Wanfang Database, CNKI, and Weipu Database were searched for the randomized controlled trials (RCTs) of HFNC versus nCPAP in the treatment of neonatal RDS published up to April 1, 2020. RevMan5.3 software was used to perform a Meta analysis of the eligible RCTs. RESULTS A total of 12 RCTs were included, with 2 861 neonates in total, among whom 2 698 neonates (94.30%) had a gestational age of ≥28 weeks and 163 (5.70%) had a gestational age of <28 weeks. For primary respiratory support, the HFNC group had a significantly higher rate of treatment failure than the nCPAP group (RR=1.86, 95%CI: 1.53-2.25, P<0.001), but there were no significant differences between the two groups in the rate of invasive mechanical ventilation (P=0.40) and the rate of use of pulmonary surfactant (P=0.77). For post-extubation respiratory support, there were no significant differences between the two groups in the treatment failure rate, reintubation rate, and total oxygen supply time (P>0.05). For primary respiratory support and post-extubation respiratory support, the HFNC group had a significantly lower incidence rate of nasal injury than the nCPAP group (P<0.001), and there were no significant differences between the two groups in the mortality rate and incidence rates of the complications such as air leak syndrome, bronchopulmonary dysplasia, and necrotizing enterocolitis (P>0.05). CONCLUSIONS Based on the current clinical evidence, HFNC has a higher failure rate than nCPAP when used as primary respiratory support for neonates with RDS, and therefore it is not recommended to use HFNC as the primary respiratory support for neonates with RDS. In RDS neonates with a gestational age of ≥28 weeks, HFNC can be used as post-extubation respiratory support in the weaning phase.

Abstract
Objective: To assess the feasibility of conducting a study comparing nasal continuous positive airway pressure (nCPAP) or heated, humidified, high flow nasal cannula (HHHFNC) on oral feeding in preterm infants.Study design: Randomized controlled pilot study in a level III NICU, of infants' born ≤28°/7 weeks who at 34°/7 weeks post menstrual age (PMA) were dependent on noninvasive ventilation (NIV). Infants were randomized evenly to nCPAP or HHHFNC groups and orally fed on low-flow oxygen. The primary outcomes of enrollment and retention were assessed.Results: We enrolled 40 infants and 12 completed the study in the nCPAP group versus 13 in the HHHFNC group. Using our respiratory and feeding protocols, we showed overall enrollment and retention rates (95%CI) at 0.66 (0.54, 0.77) and 0.63 (0.48, 0.78), respectively. Breastfeeding rates were 82% in the nCPAP group and 76% in the HHHFNC group. Infants in the HHHFNC group reached full feeds 7 days earlier than those in the nCPAP groupConclusions: Based on our retention rate, an adequately powered randomized controlled trial can be performed to confirm or refute that HHHFNC is associated with achieving oral feeds earlier.Trial registration: United States National Library of Medicine (www.clinicaltrials.gov) Identifier: NCT02055339.

Abstract
BACKGROUND The optimal method to wean preterm infants from non-invasive respiratory support (NIVRS) with nasal continuous positive airway pressure (CPAP) or high-flow nasal cannula is still unclear, and methods used vary considerably between neonatal units. OBJECTIVE Perform a systematic review and meta-analysis to determine the most effective strategy for weaning preterm infants born before 37 weeks' gestation from NIVRS. METHOD EMBASE, MEDLINE, CINAHL, Google and Cochrane Central Register of Controlled Trials were searched for randomised controlled trials comparing different weaning strategies of NIVRS in infants born before 37 weeks' gestation. RESULTS Fifteen trials (1.547 infants) were included. With gradual pressure wean, the relative risk of successful weaning at the first attempt was 1.30 (95% CI 0.93 to 1.83), as compared with sudden discontinuation. Infants were weaned at a later postmenstrual age (PMA) (median difference (MD) 0.93 weeks (95% CI 0.19 to 1.67)). A stepdown strategy to nasal cannula resulted in an almost 3-week reduction in the PMA at successful weaning (MD -2.70 (95% CI -3.87 to -1.52)) but was associated with a significantly longer duration of oxygen supplementation (MD 7.80 days (95% CI 5.31 to 10.28)). A strategy using interval training had no clinical benefits. None of the strategies had any effect on the risk of chronic lung disease or the duration of hospital stay. CONCLUSION A strategy of gradual weaning of airway pressure might increase the chances of successful weaning. Stepdown strategy from CPAP to nasal cannula is a useful alternative resulting in an earlier weaning, but the focus should remain on continued weaning in order to avoid prolonged oxygen supplementation. Interval training should probably not be used.

Abstract
OBJECTIVE To determine whether delaying oral feeding until coming off NCPAP will alter feeding and respiratory-related morbidities in preterm infants. DESIGN In this retrospective pre-post analysis, outcomes were compared in two preterm infant groups (≤32 weeks gestation). Infants in Group 1 were orally fed while on NCPAP, while infants in Group 2 were only allowed oral feedings after ceasing NCPAP. RESULTS Although infants in Group 2 started feeds at a later postmenstrual age (PMA), they reached full oral feeding at a similar PMA compared with Group 1. Interestingly, there was a positive correlation between the duration of oral feeding while on NCPAP and the time spent on respiratory support in Group 1. CONCLUSIONS Delayed oral feeding until ceasing NCPAP did not contribute to feeding-related morbidities. We recommend caution when initiating oral feedings in preterm infants on NCPAP without evaluating the safety of the infants and their readiness for oral feedings.

Abstract
Previous studies on high-flow nasal cannula (HFNC) in very-low-birth-weight infants (VLBWIs) focused on comparing HFNC with nasal continuous positive airway pressure (nCPAP) to determine the usefulness of HFNC as a backup in the case of extubation failure and nasal trauma; however, the studies did not consider oral feeding. This retrospective case-control study aimed at elucidating whether HFNC could prevent the delay in feeding and achievement of full oral feeding in VLBWIs with chronic lung disease (CLD). Forty five VLBWIs were enrolled in this study: an HFNC group (n = 11) that was supported by HFNC at oral feeding initiation, and a non-HFNC group (n = 34) that could start oral feeding without HFNC. The gestational age and birth weight of the HFNC group were lower than those in the non-HFNC group. The median duration of exposure to oxygen and neonatal intensive care unit stay were comparable in both groups. The timings of oral feeding initiation and full oral feeding achievement in both groups were not significantly different: 35.3 (33.0 - 38.1) vs. 35.5 (33.7 - 42.4) weeks (P = 0.91) for the HFNC and 38.6 (34.4 - 42.3) vs. 36.7 (34.6 - 44.4) weeks postmenstrual age (P = 0.29) for the non-HFNC. Clinically significant aspiration pneumonia during the period of oral feeding was not observed in the HFNC group. Respiratory support by HFNC in VLBWIs with CLD might prevent oral feeding delay. Initiation of oral feeding of VLBWIs on HFNC might be safe and might accelerate the achievement of oral feeding milestones.

Abstract
Nasal high-flow therapy (nHF) is increasingly used for neonates, with perceived benefits including reduced rates of nasal trauma and parent and nursing staff preference. Current evidence suggests that although nHF is a reasonable alternative for postextubation support of preterm infants, continuous positive airway pressure is a superior modality for primary support of respiratory distress syndrome. Minimal evidence exists for use of nHF in extremely preterm infants less than 28 weeks' gestation. Depending on clinician preference, units may still choose nHF in some settings, although careful choice of appropriate patients, and availability of rescue continuous positive airway pressure, is essential.

Abstract
Endotracheal intubation and invasive mechanical ventilation have been mainstays in respiratory care of neonates with respiratory distress syndrome. Together with antenatal steroids and surfactant, this approach has accounted for significant reductions in neonatal mortality. However, with the increased survival of very low birthweight infants, the incidence of bronchopulmonary dysplasia (BPD), the primary respiratory morbidity of prematurity, has also increased. Arrest of alveolar growth and development and the abnormal development of the pulmonary vasculature after birth are the primary causes of BPD. However, invasive ventilation-associated lung inflammation and airway injury have long been believed to be important contributors. In fact, discontinuing invasive ventilation in favor of noninvasive respiratory support has been considered the single best approach that neonatologists can implement to reduce BPD. In this review, we present and discuss the mechanisms, efficacy, and long-term outcomes of the four main approaches to noninvasive respiratory support of the preterm infant currently in use: nasal continuous positive airway pressure, high-flow nasal cannula, nasal intermittent mandatory ventilation, and neurally adjusted ventilatory assist. We show that noninvasive ventilation can decrease rates of intubation and the need for invasive ventilation in preterm infants with respiratory distress syndrome. However, none of these noninvasive approaches decrease rates of BPD. Accordingly, noninvasive respiratory support should be considered for clinical goals other than the reduction of BPD.

Abstract
Background: As a noninvasive respiratory support mode, high-flow nasal cannula (HFNC) is widely used in preterm infants at neonatal care units. HFNC is often used as an alternative to nasal continuous positive airway pressure (NCPAP) for initial or post-extubation respiratory support. The purpose of this meta-analysis is to evaluate and compare the efficacy and safety of HFNC and NCPAP for respiratory support in preterm infants.Methods: We searched PubMed, Web of Science, Embase, Cochrane Library, Clinicaltrials.gov, Controlled-trials.com, Google Scholar, VIP, and Wang Fang for articles from their inception to December 2018. All published randomized controlled trials (RCTs) evaluating and comparing the effects of HFNC and NCPAP therapy for primary respiratory support in newborns were included. All meta-analyses were performed using Review Manager 5.3.Results: In total, 21 RCTs involving 2886 preterm infants were included. The results of the meta-analysis revealed the following: (1) for primary respiratory support, the rates of treatment failure at trial entry were similar between HFNC and CPAP (relative risk 1.03, 95% confidence interval 0.79-1.33), and HFNC had reduced nasal trauma (p < .00001); and (2) for respiratory support after extubation, CPAP was associated with a lower likelihood of treatment failure than HFNC (relative risk 1.23, 95% confidence interval 1.01-1.50). The incidences of nasal trauma and pneumothorax in the HFNC group were significantly lower than that in the CPAP group (p < .0001 and p = .03). Serious adverse events did not significantly differ.Conclusions: HFNC had effects similar to those of CPAP regarding the failure of initial respiratory support in premature infants and was associated with reduced nasal trauma compared to CPAP. Following extubation, CPAP had fewer treatment failures than HFNC, but CPAP had a significantly increased rate of nasal trauma and pneumothorax. Further studies are needed to clarify the potential benefits of HFNC as primary respiratory support in extremely low birth weight or extremely preterm infants.

Abstract
BACKGROUND Oral feeding skills of moderately preterm infants are not mature at birth. AIMS To establish the relationship between postmenstrual age at introduction of first oral feeding and attainment of full oral feeding and hospital discharge for moderately preterm infants. STUDY DESIGN Multicenter retrospective analysis of a prospective cohort of moderately preterm infants admitted to a Eunice Kennedy Shriver National Institute of Child Health and Human Development Neonatal Research Network hospital. SUBJECTS 6146 infants born at 29-33 weeks' gestation from January 2012 to November 2013. OUTCOME MEASURES Postmenstrual age at full oral feeding and at hospital discharge. RESULTS The median postmenstrual age at first oral feeding was 33.9 weeks (interquartile range 33.1-34.3). For each week earlier at first oral feeding, full oral feeding occurred 4.5 days earlier (p < 0.0001) and hospital stay was shortened by 3.4 days (p < 0.0001). Higher birth weight (p < 0.0001) and black maternal race (p = 0.0001) were associated with younger postmenstrual age at full oral feeding and at discharge. CONCLUSION Moderately preterm infants with earlier introduction of oral feeding achieved earlier full oral feeding and hospital discharge.

Abstract
Several treatments have been proposed to shorten the time to the attainment of full oral feeding (FOF) for premature infants, but there are only a few evaluation methods useful in estimating predictors of this period. We investigated whether specific items within the disorganized sucking patterns described by the Neonatal Oral-Motor Assessment Scale (NOMAS) could estimate the time to FOF in preterm infants with feeding difficulty. Preterm infants diagnosed with a disorganized sucking pattern in the NOMAS evaluation before 50 weeks of postmenstrual age were included. Video recordings of at least 2 min of oral feeding were further analyzed retrospectively by two assessors and the premature infants who exhibited disorganized sucking patterns (n = 109) were divided into three clusters (clusters 2-4). The observational items compatible with disorganization in the original NOMAS were divided into three groups: cluster 2 (disorganized: arrhythmical), cluster 3 (disorganized: arrhythmical + unable to sustain), and cluster 4 (disorganized: arrhythmical + incoordination ± unable to sustain) and further divided into incoordination-positive (cluster 4) and incoordination-negative groups (clusters 2 and 3). Premature infants in the incoordination-positive group (cluster 4, which means stress signals) showed a median transition time of 22 days (range: 4-121 days) which was longer than that in the incoordination-negative group (median 6 days; range: 1-25 days). Univariate linear regression analysis revealed that the presence of incoordination among disorganized sucking patterns (NOMAS cluster 4 vs. clusters 2 and 3), birth weight, total parenteral nutrition (TPN) duration, non-invasive positive pressure ventilation duration, the presence of moderate to severe bronchopulmonary dysplasia, pulmonary hypertension, sepsis, small for gestational age (SGA), and necrotizing enterocolitis are associated with the transition time to FOF. In a multivariate linear regression analysis, the variables revealed to be associated with the transition time were TPN duration, SGA, and the presence of stress signals (incoordination-positive group) among disorganized sucking patterns. When selecting premature infants to be treated with swallowing therapy, it is reasonable to pay more attention to the incoordination-positive group described in the NOMAS, that is, premature infants with stress signals to shorten the time to attain FOF.

Nasal high flow therapy in very low birth weight infants with mild respiratory distress syndrome: a single center experience. Ital J Pediatr 2017; 43:116. [PMID: 29282094 PMCID: PMC5745898 DOI: 10.1186/s13052-017-0438-9] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/01/2017] [Accepted: 12/11/2017] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND Pulmonary disorders and respiratory failure represent one of the most common morbidities of preterm newborns admitted to neonatal intensive care units (NICUs). The use of nasal high-flow therapy (nHFT) has been more recently introduced into the NICUs as a non-invasive respiratory (NIV) support. METHODS We performed a retrospective study to evaluate safety and effectiveness of nHFT as primary support for infants born < 29 weeks of gestation and/or VLBW presenting with mild Respiratory Distress Syndrome (RDS). The main outcome was the percentage of patients that did not need mechanical ventilation. Secondary outcomes were rate of bronchopulmonary dysplasia (BDP), air leaks, nasal injury, late onset sepsis (LOS), intraventricular hemorrhage (IVH), retinopathy (ROP), necrotizing enterocolitis (NEC), hemodynamically-significant patent ductus arteriosus (PDA) and death. RESULTS Sixty-four preterm newborns were enrolled. Overall, 93% of enrolled patients did not need mechanical ventilation. In a subgroup analysis, 88.5% of infants < 29 weeks and 86.7% of infants ELBW (< 1000 g BW) did not need mechanical ventilation. BPD was diagnosed in 26.6% of preterms enrolled (Mild 20%, Moderate 4.5%, Severe 1.5%). In subgroup analysis, BPD was diagnosed in 53.9% of newborns with GA < 29 weeks, in 53.3% of ELBW newborns and in 11.1% of small for gestational age (SGA) newborns. Neither air leaks nor nasal injury were recorded as well as no exitus occurred. LOS, IVH, ROP, NEC and PDA occurred respectively in 16.1%, 0%, 7.8%, and 1.6% of newborns. CONCLUSIONS According to our results, n-HFT seems to be effective as first respiratory support in preterm newborns with mild RDS. Further studies in a larger number of preterm newborns are required to confirm nHFT effectiveness in the acute phase of RDS.

Samson N, Nadeau C, Vincent L, Cantin D, Praud JP. Effects of Nasal Continuous Positive Airway Pressure and High-Flow Nasal Cannula on Sucking, Swallowing, and Breathing during Bottle-Feeding in Lambs. Front Pediatr 2017; 5:296. [PMID: 29387680 PMCID: PMC5776098 DOI: 10.3389/fped.2017.00296] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/04/2017] [Accepted: 12/21/2017] [Indexed: 12/02/2022] Open
Abstract
The use of prolonged respiratory support under the form of high-flow nasal cannula (HFNC) or nasal continuous positive airway pressure (nCPAP) is frequent in newborn infants. Introduction of oral feeding under such nasal respiratory support is, however, highly controversial among neonatologists, due to the fear that it could disrupt sucking, swallowing, and breathing coordination and in turn induce cardiorespiratory events. The recent observation of tracheal aspirations during bottle-feeding in preterm infants under nCPAP justifies the use of animal models to perform more comprehensive physiological studies on the subject, in order to gain further insights for clinical studies. The objective of this study was to assess and compare the impact of HFNC and nCPAP on bottle-feeding in newborn lambs, in terms of bottle-feeding efficiency and safety as well as sucking-swallowing-breathing coordination. Eight full-term lambs were instrumented to record sucking, swallowing, and respiration as well as electrocardiogram and oxygenation. Lambs were bottle-fed in a standardized manner during three randomly ordered conditions, namely nCPAP 6 cmH2O, HFNC 7 L/min, and no respiratory support. Results revealed that nCPAP decreased feeding duration [25 vs. 31 s (control) vs. 57 s (HFNC), p = 0.03] and increased the rate of milk transfer [2.4 vs. 1.9 mL/s (control) vs.1.1 mL/s (HFNC), p = 0.03]. No other indices of bottle-feeding safety or sucking-swallowing-breathing coordination were significantly altered by HFNC or nCPAP. In conclusion, our results obtained in full-term newborn lambs suggest that: (i) nCPAP 6 cmH2O, but not HFNC 7 L/min, increases bottle-feeding efficiency; (ii) bottle-feeding is safe under nCPAP 6 cmH2O and HFNC 7 L/min, with no significant alteration in sucking-swallowing-breathing coordination. The present informative and reassuring data in full-term healthy lambs must be complemented by similar studies in preterm lambs, including mild-to-moderate respiratory distress alleviated by respiratory support in order to mimic preterm infants with bronchopulmonary dysplasia and pave the way for clinical studies.
