Background: Extremely preterm infants (EPIs) frequently encounter challenges in feeding due to their underdeveloped digestive systems. Attaining full enteral feeding at the earliest possible stage can facilitate the removal of vascular catheters and decrease catheter-related complications. Methods: We performed a retrospective cohort study comprising 145 extremely preterm infants with a gestational age < 28 weeks who underwent non-invasive mechanical ventilation at Shenzhen Maternity & Child Healthcare Hospital between January 2019 and June 2020. The KMC group received standard nursing care along with KMC, while the control group received standard nursing care without KMC. KMC initiation took place three weeks after admission and continued for a period of two weeks or more while maintaining stable vital signs. We evaluated the rate of exclusive breastmilk feeding within 24 h prior to discharge and the time to full enteral feeding throughout hospitalization. Additionally, we conducted a multiple linear regression analysis to identify the independent factors associated with exclusive breastmilk feeding rates and the time to full enteral feeding. Results: The KMC group exhibited a significantly higher rate of exclusive breastmilk feeding in the 24 h before discharge in comparison to the Non-KMC group (52.8% vs. 31.5%, OR 2.43; 95% CI 1.24, 4.78). Moreover, the KMC group achieved full enteral feeding in a shorter duration than the Non-KMC group (43.1 ± 9.6 days vs. 48.7 ± 6.9 days, p < 0.001). Multiple linear regression analysis revealed that KMC was an independent protective factor associated with improved exclusive breastmilk feeding rates (OR 2.43; 95% CI 1.24, 4.78) and a reduction in the time to full enteral feeding (β -5.35, p < 0.001) in extremely preterm infants. Conclusion: Kangaroo Mother Care (KMC) can expedite the achievement of full enteral feeding and enhance exclusive breastmilk feeding rates in extremely preterm infants receiving non-invasive assisted ventilation. These findings highlight the beneficial effects of KMC on the feeding outcomes of this vulnerable population, underscoring the importance of implementing KMC as a part of comprehensive care for extremely preterm infants.

This study investigated the effects of exclusive donor milk or formula in the first 7 days after birth, on the time to full enteral feeding, growth, and morbidity of adverse events related to premature infants. This was a retrospective study carried out from July 2014 to December 2019 at the Department of Neonatology of Shanghai Children’s Hospital. All infants with a birth weight

Background: The transition to full enteral feeding is important for ensuring adequate growth in preterm infants. Aims: The aim of this study was to investigate the effects of two different intermittent feeding methods on the transition to full enteral feeding in preterm infants. Study design: A prospective, randomized controlled study was conducted in a neonatology and perinatology center. Subjects: Preterm infants with a gestational age between 24 + 0/7 and 31 + 6/7 were included in this study. They were divided into two groups: the SIF (slow infusion feeding) group and the IBF (intermittent bolus feeding) group. In the SIF group, feed volumes were administered over one hour using an infusion pump through an orogastric tube, with feeding occurring every three hours. The IBF group received enteral feeding using a gravity-based technique with a syringe through an orogastric tube, completed within 10 to 30 min. Outcome measures: The primary outcome was the achievement of full enteral feeding and the occurrence of feeding intolerance. Results: A total of 103 infants were enrolled in the study (50 in SIF and 53 in IBF). The time to achieve full enteral feeding did not differ significantly between the two groups (p = 0.20). The SIF group had significantly fewer occurrences in which gastric residual volume exceeded 50% (p = 0.01). Moreover, the SIF group had a significantly shorter duration of non-per-oral (NPO) status than the IBF group (p = 0.03). Conclusions: It is our contention that the use of the SIF method as an alternative feeding method is appropriate for infants with feeding intolerance and those at high risk of feeding intolerance.

Aim: We propose a new technique for feeding a malnourished patient with a "high" double-barrel jejunostomy (at about 60 cm from the Treitz Ligament). The procedure aims to restore an adequate nutritional state maintaining a correct diet for 24 h a day, without complications and without interfering with the normal activity of the nurses caring for the stoma. Method: Using local anesthesia, we introduced a Reverdin needle through the efferent loop of jejunostomy and externalized it through the skin, medially from jejunostomy of about 10 cm. Using this guide, we inserted an enteral feeding tube with a blunt tip and then introduced it through the efferent loop to reach about 40 cm distantly into the bowel. Results: The stoma output decreased from 3 to 1.5 L/day; kidney status was restored to normal function. Conclusion: The main advantages are the minimal invasiveness of the implantation procedure, the possibility of nutrition during all 24 h, and the easy management by nurses. [ABSTRACT FROM AUTHOR]

Objective We assessed the impact of early enteral feeding introduction during therapeutic hypothermia on time to reach full enteral feeding (FEF) and other feeding related outcomes in infants born at ≥35 weeks gestational age and diagnosed with moderate to severe Hypoxic-Ischemic Encephalopathy. Methods A prospective cohort with historical control study, conducted on infants admitted to the Alberta Children’s Hospital level III NICU in Calgary between January 2013 and December 2018. Infants were divided into 2 groups: (1) unfed group (UG), which was kept nil per os during the 72 h of therapeutic Hypothermia (TH), with subsequent introduction of feeding and gradual increase to FEF; (2) fed group (FG), which received feeding at 10 mL/kg/day during TH then increased gradually to FEF. Groups were compared for time to FEF and the type of milk they were being fed on discharge. Other gut related health risks such as NEC and sepsis were examined. Results During the study period, 146 infants received therapeutic hypothermia, of whom 75 in the UG and 71 in the FG. The FG compared to the UG received the first feed sooner after TH initiation (median 57 vs. 86.5 h, p < .001), reached FEF earlier (median 6 vs. 8 days, p = .012), had a higher rate of being fully fed in the first week of life (70 vs. 53%, p < .035), was kept NPO for shorter duration (median 2 vs. 4 days, p < .001), and had a higher rate of breast milk feeding at discharge (41 vs. 13%, p < .001). There were no cases of necrotizing enterocolitis or late onset sepsis in either group during the hospital stay. Conclusion Minimal enteral feeding during therapeutic hypothermia appears to be safe and leads to a shorter time to FEF and higher rates of breast milk feeding at discharge. [ABSTRACT FROM AUTHOR]

While probiotics are reported to reduce the risks of neonatal morbidities, less is known about probiotics and feeding tolerance. With this retrospective cohort study, we investigate whether introduction of probiotic supplementation as the standard of care was associated with fewer neonatal morbidities and improved feeding tolerance in very preterm infants. Using the Swedish Neonatal Quality Register, 345 live-born very preterm infants (28–31 weeks' gestation), from January 2019–August 2021, in NICUs in Stockholm, Sweden, either received probiotic supplementation (Bifidobacterium infantis, Bifidobacterium lactis, Streptococcusthermophilus) (139) or no supplementation (206); they were compared regarding a primary composite outcome of death, sepsis, and/or necrotising enterocolitis and secondary outcomes: time to full enteral feeding and antibiotics use. Probiotics seemed associated with a reduced risk of the composite outcome (4.3% versus 9.2%, p = 0.08). In the subgroup of 320 infants without the primary outcome, probiotics were associated with shorter time to full enteral feeding (6.6 days versus 7.2 days) and less use of antibiotics (5.2 days versus 6.1 days). Our findings suggest that probiotics improve feeding tolerance and further support that very preterm infants may benefit from probiotic supplementation. [ABSTRACT FROM AUTHOR]

Abstract Background Delayed meconium evacuation is an important cause of intestinal dysfunction in preterm infants. There are many methods to induce defecation in preterm infants: however, the effects are controversial. Finding a new intervention method to promote meconium evacuation in premature infants is necessary. Therefore, in the proposed study, the effectiveness of breast milk enema on complete meconium evacuation and time to achieve full enteral feeding will be investigated in preterm infants. Methods/design The study is a randomized, open-label, parallel-group, and single-center clinical trial. A total of 294 preterm infants will be recruited and stratified based on gestational age. Then, the infants will be assigned in a randomized block design to the intervention and control groups with a 1:1 ratio. Preterm infants in the control and intervention groups will receive saline enema and breast milk enema, respectively. The primary outcomes will be the time to achieve complete meconium evacuation from birth and time to achieve full enteral feeding from birth in preterm infants. The secondary outcomes will include hospitalization days, body weight at discharge, duration of total parenteral nutrition, cholestasis, and adverse events. Discussion The results of this trial will determine whether breast milk enema shortens the time to complete meconium evacuation and the time to achieve full enteral feeding in extremely preterm and preterm infants. Furthermore, the study results may provide a new, safe, inexpensive, and easy-to-use intervention to effectively evacuate meconium in preterm infants.

• Citrulline levels decreased during the first 48 h after NEC onset. • Citrulline 0–48 h after NEC onset was not associated with the type of treatment. • Citrulline 0–48 h after NEC onset was not associated with survival. • Higher citrulline 0–24 h after NEC onset was related to a faster intestinal recovery. Levels of plasma citrulline (citrulline-P), a biomarker for enterocyte function, might be useful for the monitoring the course of necrotizing enterocolitis (NEC). Our aim was to evaluate whether citrulline-P levels during the first 48 h (h) after NEC onset were associated with need for surgery, survival, and intestinal recovery. In preterm infants with NEC (Bell's stage ≥2) we measured citrulline-P levels during the first 48 h after NEC onset. Categorizing the measurements into 0–8 h, 8–16 h, 16–24 h, 24–36 h, and 36–48 h, we determined the course of citrulline-P using linear regression analyses. Next, we analyzed whether citrulline-P levels measured at 0–24 h and 24–48 h differed between conservative and surgical treatment, survivors and nonsurvivors, and equal/below and above total group's median time to full enteral feeding (FEFt). We included 48 infants, median gestational age 28.3 [IQR:26.0–31.4] weeks, birth weight 1200 [IQR:905–1524] grams. Citrulline-P levels decreased the first 48 h (B per time interval: -1.40 μmol, 95% CI, −2.73 to −0.07, p = 0.04). Citrulline-P was not associated with treatment, nor with survival. Citrulline-P at 0–24 h, but not 24–48 h, was higher in infants with FEFt ≤20 days than in infants with FEFt >20 days (20.7 [IQR:19.9–25.3] µmol/L (n = 13) vs. 11.1 [IQR:8.4–24.0] µmol/L (n = 11), p = 0.049), with a citrulline-P cut-off value of 12.3 μmol/L. Citrulline-P levels decreased the first 48 h after NEC onset, suggesting on-going intestinal injury. In survivors, measuring citrulline-P in the first 24 h after NEC onset may provide an indication for intestinal recovery rate. [ABSTRACT FROM AUTHOR]

Background Early enteral feeding is one of the efforts to improve gastrointestinal adaptability in preterm infants. Volume advancement (VA) enteral feeding has been associated with less time to reach full feeding, which can improve outcomes. Objective To evaluate the duration of VA needed to achieve full enteral feeding (FEF) in low birth weight (LBW) and very low birth weight (VLBW) infants and related factors. Methods This prospective study was done in infants with birth weight 1,000 to <2,000 grams in the Neonatal Ward and NICU of Dr. Moh. Hoesin General Hospital, Palembang, South Sumatera. All infants underwent VA feeding. The time needed to achieve FEF (150 mL/kg/day) was recorded. Several clinical factors were analyzed for possible associations with the success rate of achieving FEF within 10 days of feeding. Results Thirty-five infants were included in this study with a mean gestational age of 31.83 (SD 2.67) weeks. Their median body weight at the start of protocol was 1,400 (range 1,000-1,950) grams and 80% had hyaline membrane disease. Median time to achieve FEF was 11 (range 8-21) days, with 48.6% subjects achieving FEF in =10 days. Gestational age <32 weeks (OR 5.404, 95%CI 0.963 to 30.341), birth weight <1,500 grams (OR 5.248, 95%CI 0.983 to 28.003), and male gender (OR 4.751, 95%CI 0.854 to 26.437) were associated with the failure of achieving FEF within 10 days of feeding, however, no factors remained statistically significant after multivariate analysis. Conclusion Full enteral feedings in infants with birth weight 1,000 to <2,000 grams with VA feeding are achieved within a median of 11 days. Gestational age, birth weight, and gender are not associated with time needed to achieve FEF. [ABSTRACT FROM AUTHOR]

Pasteurized donor human milk (DHM) is the preferred alternative for infant nutrition when own mother's milk (OMM) is unavailable. Whether DHM is an efficient means for protecting preterm infants from oxidative stress remains unknown. We quantified a panel of oxidative stress biomarkers in urine samples from preterm infants (≤32 weeks of gestation and a birth weight ≤1500 g) receiving ≥80% of feeding volume as either DHM or OMM. The noninvasive in vivo assessment of oxidative stress showed no statistically significant difference between both groups at the time when full enteral nutrition (150 mL/kg body weight) was achieved and until hospital discharge. In addition, the changes of urinary biomarker levels with time were assessed. This is the first longitudinal study on oxidative stress levels in preterm infants fed with DHM in comparison with OMM. There is no statistically significant difference in urinary oxidative stress levels of preterm infants from both groups indicating that despite the effects of pasteurization, DHM is a valid alternative when OMM is not available. Based on the results, we raise the hypothesis that pasteurized DHM protects preterm infants from oxidative stress as good as OMM, and consequently, its use could prevent oxidative stress-related diseases.

Background: Great variability in enteral feeding practices for very preterm (

Limiting the number of days until achievement of full enteral feeding in extremely low birth weight neonates (ELBW; < 1000 g) might affect growth in the first years of life. This study compared the Z scores in growth over time of two cohorts of ELBW neonates that were comparable on maternal and neonatal characteristics and characteristics of hospitalization, but differed in enteral feeding strategy during neonatal admission. In the 2010-2014 cohort, full enteral feeding was achieved on average 16 days earlier than in the 2000-2005 cohort. In both cohorts, weight, height, and head circumference were recorded at birth and at the corrected ages of 9 and 24 months. A linear mixed model with repeated measures controlling for neonates small for gestational age showed no significant effect of different strategies in achievement of full enteral feeding on any anthropometric Z scores over time. Although full enteral feeding was achieved earlier in the 2010-2014 cohort, this was not associated with growth patterns during the first two years of life.Conclusion: The effect of a change in strategy to achieve full enteral feeding at an earlier stage in ELBW neonates was assessed. Early enteral feeding strategies do not necessarily improve growth during the first two years of life. What is Known: • Feeding strategies during neonatal stay may affect growth in the first years of life. • Strategies to achieve full enteral feeding earlier were implemented, but data on the impact on subsequent growth after discharge are limited. What is New: • Full enteral feeding was achieved earlier, but this was not associated with improved growth during the first 2 years of life after discharge. • Early enteral feeding strategies do not necessarily improve growth during the first 2 years of life.

Aim: This study compared the impact of using either single donor breastmilk or formula to start enteral feeding in preterm infants, on the time to full enteral feeding, growth and morbidity. The milk was provided by other preterm mothers.Methods: This was an observational prospective study, carried out from June 2012 to March 2013 at the Medical University of Vienna, Austria, on the effects of preterm single donor milk on 133 very low birthweight infants with a birthweight <1500 g and a gestational age <32 weeks until they were on full enteral feeding. They were compared to a retrospective group of 150 infants from March 2011 to May 2012 who received preterm formula.Results: The time to full enteral feeding, defined as 140 mL/kg, was significantly shorter in the donor milk group than in the formula group (18 vs. 22 days, p = 0.01). Feeding donor milk was also associated with a lower incidence for retinopathy of prematurity (4% vs. 13%, p < 0.01) and culture-proven sepsis (11% vs. 23%, p < 0.01).Conclusion: Feeding preterm infants breastmilk from a single donor rather using formula was associated with a shorter time to full enteral feeding and lower incidences of retinopathy of prematurity and sepsis.

Probiotics have been linked to a reduction in the incidence of necrotizing enterocolitis and late-onset sepsis in preterm infants. Recently, probiotics have also proved to reduce time to achieve full enteral feeding (FEF). However, the relationship between FEF achievement and type of feeding in infants treated with probiotics has not been explored yet. The aim of this systematic review and meta-analysis was to evaluate the effect of probiotics in reducing time to achieve FEF in preterm infants, according to type of feeding (exclusive human milk (HM) vs. formula). Randomized-controlled trials involving preterm infants receiving probiotics, and reporting on time to reach FEF were included in the systematic review. Trials reporting on outcome according to type of feeding (exclusive HM vs. formula) were included in the meta-analysis. Fixed-effect or random-effects models were used as appropriate. Results were expressed as mean difference (MD) with 95% confidence interval (CI). Twenty-five studies were included in the systematic review. In the five studies recruiting exclusively HM-fed preterm infants, those treated with probiotics reached FEF approximately 3 days before controls (MD -3.15 days (95% CI -5.25/-1.05), p = 0.003). None of the two studies reporting on exclusively formula-fed infants showed any difference between infants receiving probiotics and controls in terms of FEF achievement. The limited number of included studies did not allow testing for other subgroup differences between HM and formula-fed infants. However, if confirmed in further studies, the 3-days reduction in time to achieve FEF in exclusively HM-fed preterm infants might have significant implications for their clinical management.

Aim To detect predictors of feeding tolerance in intrauterine growth restriction ( IUGR) infants with or without brain-sparing effect ( BS). Methods We conducted a case-control study in 70 IUGR infants (35 IUGR with BS, matched for gestational age with 35 IUGR infants with no BS). BS was classified as pulsatility index ( PI) ratio [umbilical artery ( UAPI) to middle cerebral artery ( MCAPI) ( U/ C ratio)] > 1. Clinical parameters of feeding tolerance - days to achieve full enteral feeding ( FEF) - were compared between the IUGR with BS and IUGR without BS infants. Age at the start of minimal enteral feeding ( MEF) was analysed. Results Achievement of FEF was significantly shorter in IUGR infants without BS than in IUGR with BS. IUGR with BS started MEF later than IUGR without BS infants. Significant correlation of MEF and FEF with UA PI, U/ C ratio and CRIB score was found. Multiple linear regression analysis showed significant correlations with CRIB score and caffeine administration ( MEF only), and sepsis ( FEF only) and U/ C ratio (for both). Conclusion Impaired gut function can be early detected by monitoring Doppler patterns and clinical parameters. [ABSTRACT FROM AUTHOR]

Preterm infants are often considered too unstable to be fed enterally so they are exposed to complications related to a prolonged enteral fasting. Our study aims to compare feeding tolerance of adequate for gestational age (AGA) versus small for gestational age (SGA) infants and to evaluate which perinatal factors affect feeding tolerance (measured as time to achieve full enteral feeding, FEF). Inborn infants with a gestational age (GA) less than 32 weeks, born from January 2006 to December 2010, were eligible for this study. We enrolled 310 infants. The time to FEF was longer for SGA infants than for AGA, while a longer GA was associated to a reduced time to FEF. A beneficial effect was observed for antenatal steroids, while Apgar score below 7, the administration of inotrops or caffeine, the occurrence of sepsis or NEC and the presence of PDA were associated to a longer time to FEF. When evaluated jointly with a multivariate analysis, GA ( p < 0.0001), antenatal steroids prophylaxis ( p = 0.002), SGA ( p < 0.0001) and occurrence of NEC ( p = 0.0002) proved to have independent prognostic impact on the time to FEF. Feeding tolerance is better as GA increases, and worsen in SGA infants. Antenatal betamethasone is effective in reducing the time to FEF in both AGA and SGA. [ABSTRACT FROM AUTHOR]

Intra-uterine growth restriction (IUGR) is a severe and quite common problem in obstetrics. A condition of placental dysfunction can lead to a cardiovascular adaptation in the fetus characterized by a redistribution of cardiac output to maintain oxygen supply to the heart, adrenal glands and brain - the so-called brain sparing effect - at the expense of visceral organs (such as the gastrointestinal system). This condition may predispose IUGR infants to impaired gut function after birth. A higher incidence of necrotizing enterocolitis (NEC) is documented in IUGR preterm infants. Therefore, a common practice in neonatal intensive care units is to delay feeds to reduce the risk of feeding intolerance. Recent trials, however, have shown that early enteral feeding in IUGR infants is safe and it would appear, on the basis of the few available data, that breast milk could offer protection against NEC. This mini-review offers an update on feeding in IUGR infants. Future perspectives on the usefulness of Doppler and regional splanchnic and cerebral saturation monitoring for deciding when to start feeding are also provided., (© 2013.)
