Effect of Gastric Residual Evaluation on Enteral Intake in Extremely Preterm Infants: A Randomized Clinical Trial.

ABSTRACT:

Importance

Evaluating prefeed gastric residuals is considered routine care but has little supporting evidence.

Objective

To determine the effect of omitting prefeed gastric residual evaluation on nutritional outcomes in extremely preterm infants.

Design, setting, and participants

This single-center randomized clinical trial compared the omission of gastric residual evaluation with prefeed gastric residual evaluation. Infants were recruited from a level 4 neonatal intensive care unit and were enrolled from October 17, 2013, to October 8, 2016, and then followed up for 6 weeks after birth. Eligible participants were infants born at 32 or fewer weeks' gestation with a birth weight of 1250 g or less; they were enrolled within 72 hours after birth and within 24 hours after feeding initiation. All participants (N = 143) were included in the modified intent-to-treat analysis, which was conducted from March to July 2018.

Interventions

The residual group underwent prefeed gastric residual evaluation; the no residual group did not. Feeding decisions were made according to nutritional guidelines, and infants received only human milk.

Main outcomes and measures

The primary outcome was weekly enteral nutrition intake in mL/kg for 6 weeks after birth.

Results

Of 143 infants, 74 (51.7%) were randomized to undergo gastric residual evaluation (residual group) and 69 (48.3%) to omitted gastric residual evaluation (no residual group). The residual group comprised an even number of male and female infants (37 [50.0%]) with a mean (SD) gestational age of 27.1 (2.4) weeks and a mean (SD) birth weight of 888.8 (206.6) grams, whereas the no residual group had more male infants (36 [52.17%]), a mean (SD) gestational age of 27 (1.2) weeks, and a mean (SD) birth weight of 915.2 (180) grams. The no residual group had feedings that advanced more quickly compared with the residual group (mean weekly increase, 20.7 mL/kg/d vs 17.9 mL/kg/d; P = .02) and consumed more feedings at weeks 5 (137.2 [95% CI, 128.6-145.8]; P = .03) and 6 (141.6 [95% CI, 133.2-150.0]; P = .03). Among the secondary outcomes, the no residual group had higher mean estimated log weights (7.01 [95% CI, 6.99-7.02] vs 6.98 [95% CI, 6.97-7.00]; P = .03), had fewer episodes of abdominal distention (0.59 [95% CI, 0.34-1.01] vs 1.79 [95% CI, 1.27-2.53]; P = .001), and were discharged 8 days earlier (4.21 [95% CI, 4.14-4.28] vs 4.28 [95% CI, 4.19-4.36]; P = .01). Odds for necrotizing enterocolitis (0.058 [95% CI, 0.018-0.190] vs 0.026 [95% CI, 0.006-0.109]), death (0.004 [95% CI, 0.0003-0.046] vs 0.012 [95% CI, 0.001-0.131]), late-onset sepsis (0.970 [95% CI, 0.67-1.40] vs 1.38 [95% CI, 0.97-1.94]), and ventilator-associated pneumonia (0.084 [95% CI, 0.033-0.214] vs 0.056 [95% CI, 0.019-0.168]) were similar between groups.

Conclusions and relevance

Among extremely preterm infants, the omission of gastric residual evaluation increased the delivery of enteral nutrition as well as improved weight gain and led to earlier hospital discharge; these results may translate into evidence-based practice.

Project description:BackgroundEarly progression of feeding could influence the development of the gut microbiome.MethodsWe collected fecal samples from extremely preterm infants randomized to receive either early (feeding day 2) or delayed (feeding day 5) feeding progression. After study completion, we compared samples obtained at three different time points (week 1, week 2, and week 3) to determine longitudinal differences in specific taxa between the study groups using unadjusted and adjusted negative binomial and zero-inflated mixed models. Analyses were adjusted for a mode of delivery, breastmilk intake, and exposure to antibiotics.ResultsWe analyzed 137 fecal samples from 51 infants. In unadjusted and adjusted analyses, we did not observe an early transition to higher microbial diversity within samples (i.e., alpha diversity) or significant differences in microbial diversity between samples (i.e., beta diversity) in the early feeding group. Our longitudinal, single-taxon analysis found consistent differences in the genera Lactococcus, Veillonella, and Bilophila between groups.ConclusionsDifferences in single-taxon analyses independent of the mode of delivery, exposure to antibiotics, and breastmilk feeding suggest potential benefits of early progression of enteral feeding volumes. However, this dietary intervention does not appear to increase the diversity of the gut microbiome in the first 28 days after birth.Trial registrationClinicalTrials.gov identifier: NCT02915549.ImpactEarly progression of enteral feeding volumes with human milk reduces the duration of parenteral nutrition and the need for central venous access among extremely preterm infants. Early progression of enteral feeding leads to single-taxon differences in longitudinal analyses of the gut microbiome, but it does not appear to increase the diversity of the gut microbiome in the first 28 days after birth. Randomization in enteral feeding trials creates appealing opportunities to evaluate the effects of human milk diets on the gut microbiome.

Project description:Necrotising enterocolitis (NEC) is a potentially serious illness with significant mortality and morbidity in preterm infants. Previous studies have reported association of volume and colour (bile and blood stained) of gastric residuals (GR) with NEC. We aimed to study this association in our cohort of extremely preterm (EP) infants. In a case-control study using retrospective data (January 2006-December 2011), EP (gestation < 28 weeks) infants with confirmed NEC ≥ stage II (cases) were compared with infants without NEC (controls) matched for birth weight (BW) and gestational age (GA). Forty cases of NEC ≥ stage II diagnosed at a median (IQR) age of 16.5 days (10.3-23) were compared with 40 controls matched for gestation (± 3 days) and birth weight (± 680 g). Median maximum GR volume (GRV) from birth to the day of occurrence of NEC was significantly higher in cases vs. controls (5.9 vs.3.7 ml; p < 0.001). Increased maximum GRV was associated with NEC ≥ Stage II in adjusted analysis (aOR 1.36, 95%CI 1.06-1.75, p = 0.017). There was no significant difference in GRV between cases and controls throughout the clinical course, including 72, 48 and 24 h before the onset of NEC. However, green (65.0% vs. 27.5%, p = 0.001) and haemorrhagic GRs (45.0% vs. 27.5%, p = 0.092) were higher 24 h before the diagnosis of NEC.Conclusion: GRV was not associated with NEC ≥ stage II. However, green and haemorrhagic GRs were significantly higher 24 h before the diagnosis of the illness. Adequately powered prospective studies are needed to confirm the significance of our findings. What is Known: •It is unclear whether large volume, dark-coloured and blood-stained GRs are associated with NEC. •The value of routine monitoring of gastric residuals in preterm infants is currently being questioned. What is New: •Volume of gastric residuals was not associated with significant NEC. •Green and haemorrhagic GRs were significantly higher 24 hours before diagnosis of NEC.

Project description:BackgroundDue to insufficient evidence, extremely preterm infants (≤28 wk of gestation) rarely receive early progressive feeding (small increments of feeding volumes between 1 and 4 d after birth). We hypothesized that early progressive feeding increases the number of full enteral feeding days in the first month after birth.ObjectiveThe aim of this study was to determine the feasibility and efficacy of early progressive feeding in extremely preterm infants.DesignIn this single-center randomized trial, extremely preterm infants born between September 2016 and June 2017 were randomly assigned to receive either early progressive feeding without trophic feeding (early feeding group) or delayed progressive feeding after a 4-d course of trophic feeding (delayed feeding group). Treatment allocation occurred before or on feeding day 1. The primary outcome was the number of full enteral feeding days in the first month after birth. Secondary outcomes were death, necrotizing enterocolitis (NEC), culture-proven sepsis, growth percentiles at 36 wk postmenstrual age, use of parenteral nutrition, and need for central venous access.ResultsSixty infants were included (median gestational age: 26 wk; mean ± SD birth weight: 832 ± 253 g). The primary outcome differed between groups (median difference favoring the early feeding group: +2 d; 95% CI: 0, 3 d; P = 0.02). Early progressive feeding reduced the use of parenteral nutrition (4 compared with 8 d; P ≤ 0.01) and the need for central venous access (9 compared with 13 d; P ≤ 0.01). The outcome of culture-proven sepsis (10% compared with 27%; P = 0.18), restricted growth (weight, length, and head circumference <10th percentile) at 36 wk postmenstrual age (25% compared with 50%; P = 0.07), and the composite outcome of NEC or death (27% compared with 20%; P = 0.74) did not differ between groups.ConclusionEarly progressive feeding increases the number of full enteral feeding days in extremely preterm infants. This trial was registered at www.clinicaltrials.gov as NCT02915549.
