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.
                A total of 92 stable neonates 750-1250 g and gestational age <32 weeks were randomly 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.
                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.
                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. To evaluate the tolerance of rapid advancement of enteral feeds in VLBW babies.
                Tertiary teaching hospital.
                Randomized controlled trial.
                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 randomized 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.
                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).
                Stable VLBW neonates can tolerate rapid advancements of enteral feeding without increased risk of adverse effects. To gather information regarding the efficacy of early minimal enteral nutrition on overall feeding tolerance in extremely low birth weight infants.
                Prospective randomized controlled trial comparing the early use of minimal enteral nutrition in extremely low birth weight infants from day 2 to day 7 vs control infants. On day 8, feeding volume in both groups were advanced by 10 ml kg(-1) day(-1) until full enteral feedings were reached. Time to full feeds, number of intolerance episodes, anthropometric measurements, peak total bilirubin levels, incidence of necrotizing enterocolitis and incidence of sepsis were compared between the two groups with t-test and chi (2) test.
                Eighty-four infants were enrolled in the study but only 61 infants completed the feeding protocol. No statistically significant differences were found between the groups with regards to growth patterns, feeding tolerance, mortality, length of hospital stay and incidence of sepsis and necrotizing enterocolitis.
                Early minimal enteral nutrition use in extremely low birth weight infants did not improve feeding tolerance. To begin to determine the optimal time for initiating enteral feedings, 34 sick, very low birth weight infants were prospectively selected from all neonates of less than 1,500 g (N = 116) and randomly 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. To evaluate whether preterm neonates weighing 1000-1499 g at birth receiving rapid enteral feeding advancement at 30 mL/kg/day attain full feedings (180 mL/kg/day) earlier than those receiving slow enteral feeding advancement at 20 mL/kg/day without increase in the incidence of feeding intolerance or necrotizing enterocolitis.
                A total of 100 stable intramural neonates weighing between 1000 and 1499 g and gestational age less than 34 weeks were randomly allocated to enteral feeding (expressed human milk or formula) advancement of 20 mL/kg/day (n = 50) or 30 mL/kg/day (n = 50). RESULTs: Neonates in the rapid feeding advancement group achieved full volume feedings before the slow advancement group (median 7 days vs. 9 days) (p < 0.001), had significantly fewer days of intravenous fluids (median 2 days vs. 3.4 days) (p < 0.001), shorter length of stay in hospital (median 9.5 days vs. 11 days) (p = 0.003) and regained birth weight earlier (median 16 days vs. 22 days) (p < 0.001). There were no statistical differences in the proportion of infants with apnea, feed interruption or feed intolerance.
                Rapid enteral feeding advancements of 30 mL/kg/day are well tolerated by stable preterm neonates weighing 1000-1499 g. To determine the effect of trophic feeding on clinical outcome in ill preterm infants.
                A randomised, controlled, prospective study of 100 preterm infants, weighing less than 1750 g at birth and requiring ventilatory support and parenteral nutrition, was performed. Group TF (48 infants) received trophic feeding from day 3 (0.5-1 ml/h) along with parenteral nutrition until ventilatory support finished. Group C (52 infants) received parenteral nutrition alone. "Nutritive" milk feeding was then introduced to both groups. Clinical outcomes measured included total energy intake and growth over the first six postnatal weeks, sepsis incidence, liver function, milk tolerance, duration of respiratory support, duration of hospital stay and complication incidence.
                Groups were well matched for birthweight, gestation and CRIB scores. Infants in group TF had significantly greater energy intake, mean difference 41.4 (95% confidence interval 9, 73.7) kcal/kg p=0.02; weight gain, 130 (CI 1, 250) g p = 0.02; head circumference gain, mean difference 0.7 (CI 0.1, 1.3) cm, p = 0.04; fewer episodes of culture confirmed sepsis, mean difference -0.7 (-1.3, -0.2) episodes, p = 0.04; less parenteral nutrition, mean difference -11.5 (CI -20, -3) days, p = 0. 03; tolerated full milk feeds (165 ml/kg/day) earlier, mean difference -11.2 (CI -19, -3) days, p = 0.03; reduced requirement for supplemental oxygen, mean difference -22.4 (CI-41.5, -3.3) days, p = 0.02; and were discharged home earlier, mean difference -22.1 (CI -42.1, -2.2) days, p = 0.04. There was no significant difference in the relative risk of any complication.
                Trophic feeding improves clinical outcome in ill preterm infants requiring parenteral nutrition. This study examined the effects of stroking and a perioral and intraoral prefeeding stimulation program on healthy, growing, preterm infants in a Level II special care nursery. Only infants without cardiac, gastrointestinal, or central nervous system problems were included in the study.
                Two groups of nine randomly assigned, medically stable preterm infants, born between 30 weeks and 34 weeks gestation, were selected for the study. All infants were introduced to nipple feeding at approximately 34 weeks postconceptual age. The infants in the control group received a 5-min stroking protocol before feeding; the infants in the experimental group received a 5-min stroking protocol in addition to a perioral and intraoral stimulation program.
                Compared with the control group, the experimental group had a decreased number of gavage feedings, greater weight gain, and fewer days of hospitalization. The experimental group also had higher scores on the Revised-Neonatal Oral Motor Assessment nutritive suck scale than the control group.
                On a preliminary basis, the findings from this study establish the efficacy of occupational therapy in a Level II special care nursery for healthy, growing, preterm infants. Further, the specific treatment strategies conducted with the infants receiving the experimental procedures have also been preliminary established as effective in enhancing the infants' feeding skills, resulting in weight gain and decreased hospital stays as compared with their counterparts in the control group. However, our findings cannot be generalized to preterm infant populations who are at greater medical risk than the infants in our study because of the potentially hazardous effects that could result. Implications of the results for intervention programs and future research are discussed. We set out to test whether premature infants were able to be fed orally on feeding cues and be discharged home earlier than infants fed by traditional feeding regimens. Attainment of adequate growth, adverse events, and nursing time to provide care were also assessed. After screening, the recruited premature infants (< 36 wks post-conceptual age [PCA]) were divided into two feeding regimens. A control group of 40 infants was fed using an initial combination of scheduled gavage and bottle feeding and then graduating to demand feeds. The intervention group comprised 39 neonates who had gavage feeds discontinued at study entrance and fed orally on cues. Outcomes measured were: weight gain in grams/kg/day, length of stay (in days) after enrollment, PCA on entrance and at discharge, adverse events during feeding, number of cues per feed in the intervention group, and resource utilization using nurse/patient ratios. Differences between groups were evaluated using Mann-Whitney U test, Fisher's exact test, and regression analysis. Two-tailed P values of < 0.05 were considered significant. There was no difference between groups in the mean weight gain; in the control group mean weight gain was 12.5 gm/kg/day and in the intervention group 12.1 gm/kg/day ( P = 0.83). The average length of stay in the control group of 14.5 days was significantly longer than the 10.0 days in the intervention group ( P = 0.009). This difference remained significant after adjusting for gestational age at birth in regression analysis. The average total number of adverse events in the control group (12.5 events) was significantly greater than in the intervention group (3.5 events; P = 0.007). The mean PCA on study entry was 34.4 wks in both groups and on exit 36.5 wks in the control group and 35.8 wks in the intervention group, a significant difference ( P = 0.02), The intervention group elicited 2.8 cues/feed. The nurse to patient ratios was equal in both groups throughout the study period. Cue-based feeding was possible for premature infants with similar weight gain as traditional feeding without affecting workload. Hospitalization and adverse events were decreased.
The available trial data do not provide evidence of important beneficial or harmful effects of early trophic feeding for very preterm or very low birth weight infants. The applicability of these findings to extremely preterm, extremely low birth weight or growth restricted infants is limited. Further randomised controlled trials would be needed to determine how trophic feeding compared with enteral fasting affects important outcomes in this population.
