ABSTRACT
Background: To evaluate the efficacy of Gastric Residual Volume (GRV) as a measure of feed intolerance /Necrotising enterocolitis in Very Low Birth Weight (VLBW) infants.Methods: This prospective observational cohort study was done in a tertiary care hospital located in rural South India for a period of 2 years. All haemodynamically stable infants born between 30-34 weeks of gestation at birth and 1000-1500 grams of birth weight, admitted to Neonatal Intensive Care Unit (NICU) within first 24 hours of life during study period were enrolled in two groups; GRV group, where pre-feed gastric residual volume' was checked and No-GRV group, where pre-feed gastric residual volume' was not checked.Results: Both groups had similar baseline characteristics. In No-GRV group, the days to reach birth weight (12.1) and days to attain full feeds (8.0) were less when compared to GRV group. In No-GRV group, average duration of NICU stay in days (16.60) and parenteral nutrition (5.25) was less when compared to GRV group. No-GRV group does not have increased incidence of sepsis or mortality compared to GRV group. In this study there was increased incidence of NEC noted in GRV group (30%) when compared to No-GRV group (p value-0.02).Conclusions: In hemodynamically stable preterm VLBW infants, it is recommended not to check gastric residual volume routinely prior to the enteral feeding.
ABSTRACT
PURPOSE: The routine evaluation of gastric residuals (RGR) is considered standard care for premature infants. This study evaluated the usefulness of RGR in premature infants.METHODS: The study retrospectively investigated 208 premature infants (gestational aged under 34 weeks) who underwent gavage feeding in a neonatal intensive care unit at a tertiary hospital. The patients were divided into two groups: RGR (n=104) and no-RGR (n=104). Those in the no-RGR group had their gastric residuals checked only if signs of feeding intolerance were present. Clinical outcomes, including the time to reach full enteral feeding (FEF) and the incidences of gastrointestinal disorders such as feeding intolerance (FI) and necrotizing enterocolitis (NEC), were compared. Data were analyzed with SPSS ver. 21, using a Mann-Whitney U test, chi-squared test, and Fisher's exact test.RESULTS: There was no statistically significant difference for the time to FEF (z=−0.61, p =.541), incidence of FI (χ²=0.38, p =.540), and NEC (χ²=1.42, p =.234) between the two groups.CONCLUSION: No-RGR did not increase the risk for FI or NEC. These results suggest that RGR evaluation may not improve nutritional outcomes in premature infants. Recommendations for further research and practice guidelines will be provided.
