    Input: Objective To determine whether feeding with 2-hourly or 3-hourly feeding interval reduces the time to achieve full enteral feeding and to compare their outcome in very low birthweight preterm infants . Design Parallel-group r and omised controlled trial with a 1:1 allocation ratio . Setting Two regional tertiary neonatal intensive care units . Patients 150 preterm infants less than 35 weeks gestation with birth weight between 1.0 and 1.5 kg were recruited . Interventions Infants were enrolled to either 2-hourly or 3-hourly interval feeding after r and omisation . Blinding was not possible due to the nature of the intervention . Main outcome measures The primary outcome was time to achieve full enteral feeding ( ≥100 mL/kg/day ) . Secondary outcomes include time to regain birth weight , episode of feeding intolerance , peak serum bilirubin levels , duration of phototherapy , episode of necrotising enterocolitis , nosocomial sepsis and gastro-oesophageal reflux . Results 72 infants were available for primary outcome analysis in each group as three were excluded due to death — three deaths in each group . The mean time to full enteral feeding was 11.3 days in the 3-hourly group and 10.2 days in the 2-hourly group ( mean difference 1.1 days ; 95 % CI −0.4 to 2.5 ; p=0.14 ) . The mean time to regain birth weight was shorter in 3-hourly group ( 12.9 vs 14.8 days , p=0.04 ) . Other subgroup analyses did not reveal additional significant results . No difference in adverse events was found between the groups . Conclusion 3-hourly feeding was comparable with 2-hourly feeding to achieve full enteral feeding without any evidence of increased adverse events . Trial registration number ACTRN12611000676910 , pre- result Background of the study Enteral feeding in preterm neonates with intrauterine growth restriction ( IUGR ) and absent or reversed end diastolic flow ( AREDF ) on umbilical artery ( UA ) Doppler is delayed owing to an increased risk of necrotizing enterocolitis ( NEC ) . Delaying enteral feeding with longer duration of parenteral nutrition ( PN ) carries an increased risk of sepsis . Objectives To study early versus late feeding in preterm IUGR neonates for time required to attain sufficient feed volume to discontinue PN and increased risk of NEC or feed intolerance ( FI ) . Design Open-label r and omized controlled trial . Setting Tertiary care neonatal unit and fetal-maternal medicine unit in India . Participants Preterm intrauterine growth restricted neonates ' ≤32 weeks with AREDF on UA Doppler enrolled from 1 January 2014 to 31 July 2015 . Intervention R and omized to receive early or late feeding using mothers own or donor breast milk as per a feed initiation and advancement protocol . Primary outcome Time in days required to attain sufficient feed volume allowing discontinuation of PN and incidence of NEC in neonates fed early versus late . Results There were 77 eligible neonates . Sixty-two neonates were included and stratified as extreme preterm ( 27 - 29 weeks ) ( n = 20 ) and very preterm ( 30 - 32 weeks ) ( n = 42 ) . Ten extreme preterm and 21 very preterm neonates were r and omized to each early feeding and late feeding arm . There was a significantly faster attainment of sufficient feeds in the early feeding arm of both the stratified groups [ extreme preterm : median 14 days ( Interquartile range IQR : 12 - 15 ) compared with 18 days ( IQR : 18 - 20 ) , hazard ratio ( HR ) : 1.59 , 95 % CI : 0.626 - 4.078 ; very preterm : 12 days ( IQR : 10 - 14 ) as compared with 16 days ( IQR 15 - 17 ) , HR : 1.89 , 95 % CI : 1.011 - 3.555 ] . There was no difference in the incidence of NEC , FI and combined outcome of NEC and FI . Conclusion Early feeding in preterm IUGR neonates with AREDF on antenatal UA Doppler allowed earlier discontinuation of PN , allowing birth weight to be regained earlier and did not increase the incidence of NEC and FI 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 Background : Breastfeeding at discharge among sick low-birth-weight ( LBW ) infants is low despite counseling and intervention like kangaroo mother care ( KMC ) . Research aim : The aim was to study the effects of early initiation of KMC on exclusive human milk feeding , growth , mortality , and morbidities in LBW neonates compared with late initiation of KMC during the hospital stay and postdischarge . Methods : A r and omized controlled trial was conducted in level 2 and 3 areas of a tertiary care neonatal unit over 15 months . Inborn neonates weighing 1 to 1.8 kg and hemodynamically stable were r and omized to receive either  early KMC , initiated within the first 4 days of life , or late KMC ( off respiratory support and intravenous fluids ) . Follow-up was until 1 month postdischarge . Outcomes were proportion of infants achieving exclusive human milk feeding and direct breastfeeding , growth , mortality and morbidities during hospital stay , and postdischarge feeding and KMC practice s until 1 month . Results : The early  KMC  group ( n = 80 ) achieved significantly higher exclusive human milk feeding ( 86 % vs. 45 % , p < .001 ) and direct breastfeeding ( 49 % vs. 30 % , p = .021 ) in hospital and almost exclusive human milk feeding ( 73 % vs. 36 % , p < .001 ) until 1 month postdischarge than the late KMC group ( n = 80 ) . The incidence of apnea ( 11.9 % vs. 20 % , p = .027 ) and recurrent apnea requiring ventilation ( 8.8 % vs. 15 % , p = .02 ) were significantly reduced in the early KMC group . There was no significant difference in mortality , morbidities , and growth during the hospital stay and postdischarge . Conclusion : Early KMC significantly increased exclusive human milk feeding and direct breastfeeding in LBW infants AIM To compare the long-term growth and neurodevelopmental outcomes at 36 months adjusted age in preterm infants ( birthweight ( BW ) < or = 1250 g ) with necrotising enterocolitis ( NEC ) with BW-matched controls . METHODS This is a case control study performed at a regional tertiary care neonatal intensive care unit . Infants with stage II or III NEC admitted to a regional tertiary care neonatal unit between 1995 and 2000 were identified . Each infant with NEC was matched by BW ( + /-100 g ) to next two infants admitted in the unit without NEC . Growth and neurodevelopmental outcomes at 36 months are compared . RESULTS In total , 51 infants with NEC and 102 controls met study eligibility criteria and 146/153 ( 94.3 % ) were prospect ively followed for 36 months . Infants with NEC had more culture-proven sepsis ( 35.3 % vs. 10.8 % , P < 0.001 ) ; patent ductus arteriosus requiring therapy ( 64.7 % vs. 45 % , P = 0.02 ) , chronic lung disease ( 60.7 % vs. 45 % , P = 0.04 ) and longer hospital stay ( 84 days vs. 71 days , P < 0.0001 ) . There were no significant differences in growth outcomes between the two groups at 36 months . Overall 24 % of infants with NEC had one major neurodevelopmental disability compared with 10 % among control infants . Infants who developed NEC had significantly higher cognitive delay ( i.e. cognitive index < 70 ) and visual impairment . A logistic regression model identified NEC as a predictor of cognitive delay . CONCLUSION Preterm infants who develop NEC are at a significantly higher risk for developing neurodevelopmental disability . We recommend close neurodevelopmental follow up for all < or = 1250 g infants who develop stage II or III NEC Background In the UK , 1–2 % of infants are born very preterm ( < 32 weeks of gestation ) or have very low birth weight ( < 1500 g ) . Very preterm infants are initially unable to be fed nutritional volumes of milk and therefore require intravenous nutrition . Milk feeding strategies influence several long and short term health outcomes including growth , survival , infection ( associated with intravenous nutrition ) and necrotising enterocolitis ( NEC ) ; with both infection and NEC being key predictive factors of long term disability . Currently there is no consistent strategy for feeding preterm infants across the UK . The SIFT trial will test two speeds of increasing milk feeds with the primary aim of determining effects on survival without moderate or severe neurodevelopmental disability at 24 months of age , corrected for prematurity . The trial will also examine many secondary outcomes including infection , NEC , time taken to reach full feeds and growth . Methods / design Two thous and eight hundred very preterm or very low birth weight infants will be recruited from approximately 30 hospitals across the UK to a r and omised controlled trial . Infants with severe congenital anomaly or no realistic chance of survival will be excluded . Infants will be r and omly allocated to either a faster ( 30 ml/kg/day ) or slower ( 18 ml/kg/day ) rate of increase in milk feeds . Data will be collected during the neonatal hospital stay on weight , infection rates , episodes of NEC , length of stay and time to reach full milk feeds . Long term health outcomes comprising vision , hearing , motor and cognitive impairment will be assessed at 24 months of age ( corrected for prematurity ) using a parent report question naire . Discussion Extensive search es have found no active or proposed studies investigating the rate of increasing milk feeds . The results of this trial will have importance for optimising incremental milk feeding for very preterm and /or very low birth weight infants . No additional re sources will be required to implement an optimal feeding strategy , and therefore if successful , the trial results could rapidly be adopted across the NHS at low cost . Trial registration IS RCT N Registry ; IS RCT N76463425 on 5 March , 2013 Background : The interrelations between early enteral feeding , necrotising enterocolitis ( NEC ) , and nosocomial sepsis ( NS ) remain unclear . Objective : To evaluate the effect of age at the introduction of enteral feeding on the incidence of NS and NEC in very low birthweight ( VLBW < 1500 g ) infants . Methods : Data were collected on the pattern of enteral feeding  and perinatal and neonatal morbidity on all VLBW infants born in one centre during 1995–2001 .  Enteral feeding was compared between infants with and without NS and /or NEC . Results : The study sample included 385 infants . Of these , 163 ( 42 % ) developed NS and 35 ( 9 % ) developed NEC .  Enteral feeding was started at a significantly earlier mean ( SD ) age in infants who did not develop nosocomial sepsis ( 2.8 ( 2.6 ) v 4.8 ( 3.7 ) days , p = 0.0001 ) . Enteral feeding was introduced at the same age in babies who did or did not develop NEC ( 3.1 ( 2 ) v 3.7 ( 3 )

agent
Available trial data do not provide evidence that advancing enteral feed volumes at daily increments of 15 to 20 mL/kg ( compared with 30 to 40 mL/kg ) reduces the risk of NEC or death in very preterm or VLBW infants , extremely preterm or ELBW infants , SGA or growth-restricted infants , or infants with antenatal AREDFV .
Advancing the volume of enteral feeds at a slow rate results in several days of delay in establishing full enteral feeds and may increase the risk of invasive infection
