Background and Objectives : Controversy exists regarding the optimal enteral feeding regimen of very low birth weight infants ( VLBW ) . Rapid advancement of enteral feeding has been associated with an increased rate of necrotizing enterocolitis . In contrast , delaying enteral feeding may have unfavorable effects on nutrition , growth , and neurodevelopment . The aim is to compare the short-term outcomes of VLBW infants in tertiary care centers according to their enteral feeding advancement . Patients and Methods : We prospect ively studied the influence of center-specific enteral feeding advancement in 1430 VLBW infants recruited from 13 tertiary neonatal intensive care units in Germany on short-term outcome parameters . The centers were post hoc stratified to “ rapid advancement to full enteral feeds ” ( median duration of advancement to full enteral feeds ≤12.5 days ; 6 centers ) , that is , rapid advancement ( RA ) , or “ slow advancement to full enteral feeds ” ( median duration of advancement to full enteral feeds > 12.5 days ; 7 centers ) , that is , slow advancement ( SA ) . Results : VLBW infants born in centers with SA ( n = 713 ) had a significantly higher rate of sepsis compared with VLBW infants born in centers with RA ( n = 717 ) , which was particularly evident for late-onset sepsis ( 14.0 % vs 20.4 % ; P = 0.002 ) . Furthermore , more central venous lines ( 48.6 % vs 31.1 % , P < 0.001 ) and antibiotics ( 92.4 % vs 77.7 % , P < 0.001 ) were used in centers with SA . Conclusions : Center differences in enteral feeding advancement occur and may have a significant impact on short-term outcomes such as nosocomial sepsis . Large , multicenter , prospect i ve trials are required to further eluci date the optimal feeding strategy for VLBW infants OBJECTIVE Approximately 90 % of infants who develop necrotizing enterocolitis (  NEC ) do so after being fed . Previous prospect i ve studies have shown that infants given small enteral feedings  for the first 7 to 10 days of feeding do not have an increased risk for NEC compared with those given no feedings . Although neonatologists now commonly increase feeding volumes , no study has compared the risk for NEC between infants fed these small volumes and those fed volumes that are increased slowly . The purpose of this study was to compare the risks and benefits of small and increasing feeding volume . METHODS In a r and omized , controlled trial , we r and omly assigned 141 preterm infants in the newborn intensive care unit to be fed 10 days using 1 of 2 schedules . One group was fed 20 mL/kg/d for the first 10 study days ( minimal ) . The other group ( advancing ) was fed 20 mL/kg/d on study day 1 ; feeding volume was increased by 20 mL/kg/d up to 140 mL/kg/d , which was maintained until study day 10 . The main outcome measure was incidence of NEC ; secondary outcomes were maturation of intestinal motor patterns , time to reach full enteral feedings , and incidence of late sepsis . RESULTS The study was closed early because 7 infants who were assigned to advancing feeding volumes developed NEC , whereas only 1 infant fed minimal feeding volumes did , or 10 % versus 1.4 % . Although infants who were fed minimal volumes established full enteral feeding volumes later than infants who were fed advancing volumes , maturation of intestinal motor patterns and the incidence of late sepsis and feeding intolerance was similar in the 2 groups . CONCLUSION Given that advancing feeding volumes increase the risk of NEC without providing benefits for motor function or feeding tolerance , neonatologists should consider using minimal feeding volumes until future trials assess the safety of advancing feeding volumes To begin to determine the optimal time for initiating enteral feedings , 34 sick , very low birth weight infants were prospect ively selected from all neonates of less than 1,500 g ( N = 116 ) and r and omly divided into two groups . Infants were fed either on day 1 ( early ) or 7 ( late ) of life , according to a feeding protocol which included parenteral nutrition and a scheduled progression from sterile water to 2.5 % dextrose , half-strength , and finally full-strength formula over seven days . The incidence of necrotizing enterocolitis and subsequent hospital course were compared . Initiating enteral feedings on day 1 did not significantly increase the incidence of necrotizing enterocolitis , produce a clustering of cases , or induce an earlier onset of necrotizing enterocolitis . The overall incidence of necrotizing enterocolitis in sick , very low birth weight neonates was 29 % ( 5/17 ) and 35 % ( 6/17 ) in the early and late groups , respectively , compared with 4.2 % ( 2/47 ) in minimally sick , very low birth weight neonates . No significant differences between groups were seen in obstetrical complications , birth weight , gestational age , Apgar scores , presence of patent ductus arteriosus or intraventricular hemorrhage , use of umbilical catheterization , and respiratory or oxygen requirements . Infants fed enterally from day 1 did show a significantly higher energy and protein intake during the second week of life . These data show that providing dilute , early enteral calories does not adversely affect the incidence of necrotizing enterocolitis OBJECTIVE . The goal was to investigate the efficacy of orally administered probiotics in preventing necrotizing enterocolitis for very low birth weight preterm infants . METHODS . A prospect i ve , blinded , r and omized , multicenter controlled trial was conducted at 7 NICUs in Taiwan , to evaluate the beneficial effects of probiotics in necrotizing enterocolitis among very low birth weight infants ( birth weight : < 1500 g ) . Very low birth weight infants who survived to start enteral feeding were eligible and were assigned r and omly to 2 groups after parental informed consent was obtained . Infants in the study group were given Bifidobacterium bifidum and Lactobacillus acidophilus , added to breast milk or mixed feeding ( breast milk and formula ) , twice daily for 6 weeks . Infants in the control group were fed with breast milk or mixed feeding . The clinicians caring for the infants were blinded to the group assignment . The primary outcome measurement was death or necrotizing enterocolitis ( Bell 's stage ≥2 ) . RESULTS . Four hundred thirty-four infants were enrolled , 217 in the study group and 217 in the control group . The incidence of death or necrotizing enterocolitis ( stage ≥2 ) was significantly lower in the study group ( 4 of 217 infants vs 20 of 217 infants ) . The incidence of necrotizing enterocolitis ( stage ≥2 ) was lower in the study group , compared with the control group ( 4 of 217 infants vs 14 of 217 infants ) . No adverse effect , such as sepsis , flatulence , or diarrhea , was noted . CONCLUSION . Probiotics , in the form of Bifidobacterium and Lactobacillus , fed enterally to very low birth weight preterm infants for 6 weeks reduced the incidence of death or necrotizing enterocolitis Background : Necrotizing enterocolitis ( NEC ) is a frequent cause of mortality and morbidity in very low birth weight ( VLBW ) infants .  Human milk ( HM ) feeding has been associated with lower risk of NEC . However , mothers of VLBW infants often experience insufficient milk production , result ing in mixed feedings of HM and formula . Moreover , medical complications often limit the volume of feeding they can be given . Objective : To determine if high proportions of ( 50 % or greater ) HM enteral feeding within the first 14 days of life are protective against NEC . Method : This was a prospect i ve cohort study of VLBW infants who were grouped according to the HM proportion of enteral feeding in the first 14 days : < 50 % ( low human milk , LHM , n=46 ) and ⩾50 % ( high human milk , HHM , n=156 ) . The outcome of interest was development of NEC ( Bell stage 2 or 3 ) . Logistic regression was used to estimate odds ratios ( OR ) and 95 % confidence intervals ( CI ) and to assess potential confounding due to perinatal risk factors . Result : Two hundred and two infants were studied . Confirmed NEC occurred in 5/46 ( 10.6 % ) of the LHM group , as compared with 5/156 ( 3.2 % ) of the HHM . Gestational age was the only perinatal factor associated with risk of NEC . After adjustment for gestational age , HHM was associated with a lower risk of NEC ( ( OR=0.17 , 95 % CI : 0.04 to 0.68 ) , P=0.01 ) . Conclusion : Enteral feeding containing at least 50 % HM in the first 14 days of life was associated with a sixfold decrease in the odds of NEC INTRODUCTION The development of necrotizing enterocolitis is a common and serious risk to newborns . It is caused by splanchnic bed vasoconstriction that can produce intestinal necrosis . The role of onset time , type and , speed enhancements of The factors of enteral feeding related with necrotizing enterocolitis genesis such as feeding onset , type and frequency are not well understood . OBJECTIVE The incidence of necrotizing enterocolitis and mortality among infants will be compared in infants whose enteral feeding was initiated 48 hours after birth to those whose feeding began on day 5 postpartum . MATERIAL S AND METHODS A controlled clinical trial was conducted among 239 newborns weighing between 750 - 1,500 g and a gestation age of 27 - 32 weeks of gestational age . The infants were r and omly assigned to two groups--135 to an early feeding regime and 104 to delayed feeding . Breast milk or formula milk was used . Feeding was begun with one ml every six hours , progressing to three hour intervals and 20 ml/kg daily . This was increased to 150 ml/kg-d if the infant condition remained stable and it manifested no oral intolerance . RESULTS In the early feeding group , 14 ( 10;4 % ) necrotizing enterocolitis cases occurred , and in the late feeding group , 9 ( 8.7 % ) occurred ( RR= 1.22 , 95 % CI 0.49 - 3.20 , p= 0.65 ) . Five children died in early feeding group ( 3.7 % , 95 % CI 1.4 - 8.9 ) and eight in late feeding group ( 7.7 % , 95 % CI 3.6 - 15.0 , RR=0.46 , 95 % CI 0.12 - 1,60 , p= 0.18 ) . CONCLUSION Early enteral feeding in preterm newborns does not increase the risk of necrotizing enterocolitis or mortality among them ; however it represents nutritional advantages for these infants OBJECTIVE To evaluate the effect of slow vs rapid rates of advancement of enteral feed volumes on the clinical outcomes in preterm infants with 750 - 1250 g birth weight . STUDY DESIGN A total of 92 stable neonates 750 - 1250 g and gestational age < 32 weeks were r and omly allocated to enteral feeding advancement of 20 mL/kg/d ( n = 46 ) or 30 mL/kg/d ( n = 46 ) . The primary outcome was days to reach full enteral feeding , defined as 180 mL/kg/d . Secondary outcomes included rates of necrotizing enterocolitis ( NEC ) and culture-proven sepsis , days of parenteral nutrition ( PN ) , length of hospital stay , and growth end points . RESULTS Neonates in the rapid-feeding advancement group achieved full enteral volume of feedings earlier than the slower advancement group . They received significantly fewer days of PN , exhibited a shorter time to regain birth weight , and had a shorter duration of hospital stay . The incidence of NEC and the number of episodes of feeding intolerance were not significantly different between the groups , whereas the incidence of culture-proven late-onset sepsis was significantly less in infants receiving a rapid feeding advancement . Excluding infants who were small for gestational age at birth , the incidence of extrauterine growth restriction was significantly reduced in the rapid-advancement group at 28 days and at hospital discharge . CONCLUSION Rapid enteral feeding advancements in 750 - 1250 g birth weight infants reduce the time to reach full enteral feeding and the use of PN administration . Rapid-advancement enteral feed also decreases extrauterine growth restriction with improved short-term outcomes for these high-risk infants Small premature infants are often hypochlorhydric , and frequently their stomachs are colonized by enteric , gram-negative bacteria . We tested a hypothesis that gastric pH affected the colonization of the stomach with enteric bacteria and that this colonization was causally related to the risk or severity of necrotizing enterocolitis . A prospect i ve , double-blind study was conducted that compared a group of infants supplemented with 0.01–0.02 ml of 1 N HCl/ml of milk to a group with a similar supplement of water .  Gastric pH , gastric enteric bacteria counts , and the incidence and severity of necrotizing enterocolitis were monitored . The median gastric pH of the HCl-supplemented group was lower ( 3.0 ) than controls ( 4.0 ) throughout the study ( p < 0.001 ) . The gastric enteric bacterial colonization rate and the quantitative bacterial counts were strongly correlated with gastric pH over 4 ( p < 0.001 ) . Somatic growth rates in infants in the HCl-supplemented group were equal to , or exceeded , those in the control group . There was 1 case of necrotizing entero-colitis among the 34 infants in the HCl-supplemented group and 8 cases among the 34 in the control group ( p = 0.02 ) . It appears that acidifying the feedings of small premature infants to a pH low enough to inhibit bacterial proliferation in the stomach significantly lowers the risk of necrotizing enterocolitis Objective . We evaluated the efficacy of probiotics in reducing the incidence and severity of necrotizing enterocolitis ( NEC ) in very low birth weight ( VLBW ) infants . Patients and Methods . A prospect i ve , masked , r and omized control trial was conducted to evaluate the beneficial effects of probiotics in reducing the incidence and severity of NEC among VLBW ( < 1500 g ) infants . VLBW infants who started to fed enterally and survived beyond the seventh day after birth were eligible for the trial . They were r and omized into 2 groups after parental informed consents were obtained . The infants in the study group were fed with Infloran ( Lactobacillus acidophilus and Bifidobacterium infantis ) with breast milk twice daily until discharged . Infants in the control group were fed with breast milk alone . The clinicians caring for the infants were blinded to the group assignment . The primary outcome was death or NEC ( ≥ stage 2 ) . Results . Three hundred sixty-seven infants were enrolled : 180 in the study group and 187 in the control group . The demographic and clinical variables were similar in both groups . The incidence of death or NEC ( ≥ stage 2 ) was significantly lower in the study group ( 9 of 180 vs 24 of 187 ) . The incidence of NEC ( ≥ stage 2 ) was also significantly lower in the study when compared with the control group ( 2 of 180 vs 10 of 187 ) . There were 6 cases of severe NEC ( Bell stage 3 ) in the control group and none in the study group . None of the positive blood culture grew Lactobacillus or Bifidobacterium species . Conclusion . Infloran as probiotics fed enterally with breast milk reduces the incidence and severity of NEC in VLBW infants Background : Most preterm infants who develop necrotising enterocolitis ( NEC )  have received enteral feeds . Uncertainty exists about which aspects of the feeding regimen affect the risk of NEC . Aim : To examine associations between various enteral feeding practice s and the development of  NEC  in preterm infants . Methods : Multicentre case – control study . 53 preterm infants with NEC were enrolled together with a gestational age frequency-matched control without NEC from a r and omly selected neonatal unit . Clinical and feeding data were extracted and compared between the groups . Results : Significantly fewer cases than controls had received human breast milk ( 75 % vs 91 % ; OR 0.32 , 95 % CI 0.11 to 0.98 ) . The day on which enteral feeding was started did not differ significantly ( mean ( SD ) days after birth : cases 2.9 ( 2.8 ) and controls 2.8 ( 1.8 ) ) . The mean ( SD ) duration of trophic feeding ( < 1 ml/kg/h ) was significantly shorter in the cases ( 3.3 ( 3.1 ) days ) than controls ( 6.2 ( 6.7 ) days ) ( mean difference ( MD ) −2.9 , 95 % CI −4.9 to −0.9 ) days . Cases were fully fed significantly earlier than controls ( mean ( SD ) days after birth : cases 9.9 ( 4.2 ) and controls 14.3 ( 9.8 ) ; MD −4.4 , 95 % CI −7.3 to −1.5 ) . Conclusions : These data suggest that the duration of trophic feeding and rate of advancement of feed volumes may be modifiable risk factors for NEC in preterm infants . Further r and omised controlled trials are warranted to assess the effect of different rates of feed advancement on the incidence of NEC , as well as other outcomes AIMS To improve energy intake in sick very low birthweight ( VLBW ) infants ; to decrease growth problems , lessen pulmonary morbidity , shorten hospital stay , and avoid possible feeding related morbidity . Morbidity in VLBW infants thought to be associated with parenteral and enteral feeding includes bronchopulmonary dysplasia , necrotising enterocolitis , septicaemia , cholestasis and osteopenia of prematurity . METHODS A prospect i ve r and omised controlled trial ( RCT ) comparing two types of nutritional intervention was performed involving 125 sick VLBW infants in the setting of a regional neonatal intensive care unit . Babies were r and omly allocated to either an aggressive nutritional regimen ( group A ) or a control group ( group B ) . Babies in group B received a conservative nutritional regimen while group A received a package of more aggressive parenteral and enteral nutrition . Statistical analysis was done using Student’st test , the Mann-Whitney U test , the χ2 test and logistic regression . RESULTS There was an excess of sicker babies in group A , as measured by initial disease severity ( P < 0.01 ) , but mean total energy intakes were significantly higher ( P < 0.001 ) in group A at days 3 to 42 while receiving total or partial parenteral nutrition . Survival and the incidences of bronchopulmonary dysplasia , septicaemia , cholestasis , osteopenia and necrotising enterocolitis were similar in both groups . Growth in early life and at discharge from hospital was significantly better in babies in group A. There were no decreases in pulmonary morbidity or hospital stay . CONCLUSION Nutritional intake in sick VLBW infants can be improved without increasing the risk of adverse clinical or metabolic sequelae . Improved nutritional intake result ed in better growth , both in the early neonatal period and at hospital discharge , but did not decrease pulmonary morbidity or shorten hospital stay OBJECTIVE To evaluate the tolerance of rapid advancement of enteral feeds in VLBW babies . SETTING Tertiary teaching hospital . DESIGN R and omized controlled trial . METHODS All stable neonates with birth weight less than 1250 grams were included in the study . The primary outcome variable was the time taken to achieve full enteral feeds ( defined as 180 ml/kg/day ) . The secondary outcome variables were incidence of Necrotizing enterocolitis ( NNEC ) and incidence of apnea . At 48 hours , the infants were r and omized into the slow advancement group ( enteral feeds advanced by increments of 15 ml/kg/day ) or fast advancement group ( enteral feeds advanced by increments of 30 ml/kg/day ) . The monitoring during feeding included daily weight record , two hourly abdominal girth charting , gastric aspirates , apnea , time taken to reach full enteral feedings and for NNEC . RESULTS There were 53 infants who were enrolled for the study ( 27 in the fast advancement group and 26 in the slow advancement group ) . In the fast advancement group , 20 percent completed the trial ; whereas 14 ( 53.8 percent ; ) in the slow advancement group completed the study . The two groups were comparable for birth weights , gestational age , sex , intrauterine growth status , Apgar and CRIB scores . The infants in the fast group reached full enteral intake of 180 ml/kg/day significantly earlier ( 10 + /- 1.8 days ) than in the slow group ( 14.8 + /- 1.5 days ) . The two groups were comparable for episodes of feed intolerance , apnea , NNEC . Infants in the fast group regained birth weight significantly earlier ( median 18 days ) than in the slow advancement group ( median 23 days ) . CONCLUSIONS Stable VLBW neonates can tolerate rapid advancements of enteral feeding without increased risk of adverse effects NECROTIZING ENTEROCOLITIS is a serious disorder of the newborn infant that rarely occurs before the institution of oral feedings . ' -3 Various feeding practice s have been shown to be important in the pathogenesis of the disease . Low-birth-weight infants fed a hyperosmolar , 650 mOsm/1 , elemental formula  have an increased incidence of NEC when compared to low-birth-weight infants fed a cow milk formula . 4 It has also been suggested that cow milk feedings themselves or the exclusion of breast milk from the diet of small newborn infants may be predisposing factors ? The quantity of feedings in the first weeks of life may also be important , and Krouskop and associates ~ have associated the development of NEC with early institution of oral feedings . In another retrospective study , however , there were no differences between the volume of formula offered NEC patients at the time symptoms developed and infants of similar size and age who did not develop NEC . 1 Conflicting opinions therefore exist regarding the relationship of oral feeding to the development of NEC ; there have been no r and omized , prospect i ve , clinical trials dealing with this issue . The purpose s of this paper are to report the relationship of different feeding practice s in the Intermountain Newborn Intensive Care Center to the incidence of NEC , and the results of a prospect i ve controlled investigation comparing two different feeding schedules in low-birth-weight infants We studied the effect of early ( < or = 5 days ) versus delayed ( > or = 6 days ) initiation of minimal enteral feeding ( MEF ) on the incidence of necrotizing enterocolitis ( NEC ) and feeding intolerance in preterm infants with intrauterine growth restriction ( IUGR ) and abnormal antenatal Doppler results . We performed a r and omized , nonblinded pilot trial of infants receiving early or delayed MEF in addition to parenteral feeding within 48 hours of life .  Demographic data , maternal preeclampsia , antenatal steroid exposure , Doppler studies , as well as cases of NEC and feeding intolerance were all recorded . Of the 84 infants enrolled , 81 completed the study : 40 received early ( median age : 2 days , range : 1 to 5 days ) and 41 delayed ( median age : 7 days , range : 6 to 14 days ) MEF . The incidence of NEC and feeding intolerance was not significantly different between groups ( p = 0.353 and p = 0.533 , respectively ) . Birth weight was an independent risk factor for NEC in both groups . Early MEF of preterm infants with IUGR and abnormal antenatal Doppler results may not have a significant effect on the incidence of NEC or feeding intolerance . Furthermore , birth weight seems to be an independent risk factor for the development of NEC , irrespectively of the timing of MEF introduction OBJECTIVE To evaluate the efficacy of orally administered probiotics in preventing necrotizing enterocolitis ( NEC ) in preterm very low birth weight ( VLBW ) infants . STUDY DESIGN Ar and omized double blind controlled trial . PLACE AND DURATION OF STUDY The Paediatrics Department of Sylhet M.A.G. Osmani Medical College Hospital , Sylhet Bangladesh , from July 2012 to June 2015 . METHODOLOGY Preterm ( 28 - 33 weeks gestation ) VLBW ( birth weight 1000 - 1499 g ) neonates were enrolled . The study group was fed with probiotics once daily with breast milk from first feeding , and the control group with only breast milk without the addition of probiotics . Both the groups received other st and ard care . The primary outcome was the development of NEC ( stage II and III ) , categorized by modified Bell 's classification . RESULTS In 108 neonates , development of NEC was significantly lower in the study group than that of control group [ 1 ( 1.9 % ) vs. 6 ( 11.5 % ) ; p=0.044 ] . Age of achievement of full oral feeding was significantly earlier in the study group than that in the control group ( 14.88 ±3.15 and 18.80 ±4.32 days ; p < 0.001 ) . Duration of hospital stay was significantly short in the study group compared to the control group ( 15.82 ±2.94 days vs. 19.57 ±4.26 days ; p < 0.001 ) . CONCLUSION Probiotic supplementation reduces the frequency of necrotising enterocolitis in preterm neonates with very low birth weight . It is also associated with faster achievement of full oral feeding and short duration of hospital stay Background : Necrotizing enterocolitis ( NEC ) is one of the most destructive diseases associated with conditions of neonatal prematurity . Supplementation with enteral prebiotics may reduce the incidence of NEC , especially in infants who fed exclusively with breast-milk . Therefore , we compared the efficacy and safety of enteral supplementation of a prebiotic mixture ( short chain galacto-oligosaccharides/long chain fructo-oligosaccharides [ SCGOS/LCFOS ] ) versus no intervention on incidence of NEC in preterm infants . Methods : In a single-center r and omized control trial 75 preterm infants ( birth weight [ BW ] ≤1500 g , gestational age ≤34 weeks and were not fed with formula ) on 30 ml/kg/day volume of breast-milk were r and omly allocated to have enteral supplementation with a prebiotic mixture ( SCGOS/LCFOS ; 9:1 ) or not receive any prebiotic . The incidence of suspected NEC , feeding intolerance , time to full enteral feeds , duration of hospitalization were investigated . Results : Differences in demographic characteristics were not statistically important . SCGOS/LCFOS mixture significantly reduced the incidence of suspected NEC , ( 1 [ 4.0 % ] vs. 11 [ 22.0 % ] ; hazard ratio : 0.49 [ 95 % confidence interval : 0.29 - 0.84 ] ; P = 0.002 ) , and time to full enteral feeds ( 11 [ 7 - 21 ] vs. 14 [ 8 - 36 ] days ; P - 0.02 ] . Also duration of hospitalization was meaningfully shorter in the prebiotic group ( 16 [ 9 - 45 ] vs. 25 [ 11 - 80 ] ; P - 0.004 ] . Prebiotic oligosaccharides were well tolerated by very low BW ( VLBW ) infants . Conclusions : Enteral supplementation with prebiotic significantly reduced the incidence of NEC in VLBW infants who were fed exclusively breast-milk . This finding suggests that it might have been the complete removal of formula which caused a synergistic effect between nonhuman neutral oligosaccharides ( prebiotic ) and human oligosaccharides Abstract Objective : Incidence of feed intolerance ( FI ) and necrotizing enterocolitis ( NEC ) in preterm neonates with Doppler evidence of absent end diastolic flow ( AEDF ) velocities in the fetal umbilical artery when enteral feed volumes were started by 6–72 h and advanced either slowly or rapidly . Methods : Stable inborn neonates , 30–36 weeks gestation , weighing ≥1000 g and with antenatal evidence of AEDF were included in this pilot study . Infants ( stratified in < 1250 g and ≥1250 g birth weight categories ) were allocated under r and omized controlled trial , to receive either slow or rapid advancement of enteral feeding , while initiating the feeds after 6 h of birth if bowel sounds were present . Primary outcome measure was , FI and NEC till day 7 after reaching full feeds . Results : Of 159 eligible infants , 83 were r and omized : 53 infants in the ≥1250 g category ( 28 in rapid and 25 in slow group ) and 30 in the < 1250 g category ( 15 in each group ) . FI was present in 11 % versus 16 % in ≥1250 g ( p = 0.570 ) and 27 % versus 33 % in < 1250 g ( p = 0.690 ) , NEC developed in 8.4 % ( 3 versus 1 ) in ≥1250 g and ( 1 versus 2 ) in < 1250 g , in slow versus rapid feeding . Conclusion : This trial did not find increase in incidence of feed intolerance with very early introduction and rapid advancement of enteral feeds in stable preterm neonates with AEDF and birth weight ≥1250
The available trial data suggest that advancing enteral feed volumes at daily increments of 30 ml/kg to 35 ml/kg does not increase the risk of necrotising enterocolitis in very preterm or VLBW infants .
Advancing the volume of enteral feeds at slow rates result ed in several days delay in regaining birth weight and establishing full enteral feeds .
The applicability of these findings to extremely preterm , extremely low birth weight , or growth-restricted infants is limited .
BACKGROUND Early enteral feeding practice s are potentially modifiable risk factors for necrotising enterocolitis  in very preterm or very low birth weight ( VLBW ) infants .
Observational studies suggest that conservative feeding regimens , including slowly advancing enteral feed volumes , reduce the risk of necrotising enterocolitis .
However , slow feed advancement may delay establishment of full enteral feeding and be associated with metabolic and infectious morbidities secondary to prolonged exposure to parenteral nutrition .
OBJECTIVES To determine the effect of slow rates of enteral feed advancement on the incidence of necrotising enterocolitis , mortality , and other morbidities in very preterm or VLBW infants .
