ABSTRACT.Objective. To test the hypothesis that very low birth weight infants fed by continuous nasogastric gavage (CNG) would achieve full enteral feedings (100 kcal/kg/d) at an earlier postnatal age and have less feeding intolerance (FI) than infants fed by intermittent bolus gavage (IBG).Methods. Eighty infants were stratified by birth weight (700 to 1000 g and 1001 to 1250 g) and randomized into CNG or IBG feeding groups. CNG infants were comparable with IBG in birth weight, gestational age, sex, race, and day of onset of feeding (5.7 ؎ 2.1 days vs 5.6 ؎ 2.2 days, respectively). Feedings were given as undiluted Similac Special Care formula (Ross Laboratories, Columbus, OH) via a specific protocol designed for each 50 to 100 g birth weight category. Feedings were advanced isoenergetically by a maximum of 25 mL/kg/d until an endpoint of 100/kcal/kg/d for at least 48 hours was reached. An infant whose feedings were withheld for >12 hours based on predetermined criteria was considered to have an episode of FI.Results. Infants in the CNG group reached full enteral feeding at 17.1 ؎ 8.9 days compared with 15.5 ؎ 5.5 days in the IBG group; these were not statistically different. Secondary outcome variables such as days to regain birth weight (CNG, 12.6 ؎ 5 days vs IBG, 12.5 ؎ 3.7 days), days to reach discharge weight of 2040 g (CNG, 60 ؎ 13.4 days vs IBG, 62 ؎ 13.6 days), and number of episodes of FI were not significantly different between feeding methods. FI was primarily associated with birth weight <1000 g (71%) vs 1001 to 1250 g (38%).Conclusion. Feeding methods are associated with similar outcomes when feeding regimens are comparable.

Patent ductus arteriosus (PDA) is believed to be a contributing factor in the etiopathogenesis of bronchopulmonary dysplasia (BPD). We studied the effects of early dexamethasone therapy on persistent ductal patency and the role of PDA in the etiopathogenesis of BPD during the course of a randomized double-blind trial of dexamethasone to prevent BPD. Infants, who weighed between 700 and 999 g, had severe RDS, and had been given surfactant, were randomized to receive a 12-day course of dexamethasone (n = 13) or placebo (n = 17) starting within the first 12 hours of postnatal life. The diagnosis of PDA was made clinically and was confirmed by cardiac ultrasound. The incidence of clinically significant ductus in infants who weighed less than 1000 g was 23% in the dexamethasone-treated group, as compared with 59% in infants who were given placebo. This difference was marginally significant, p = 0.05, odds ratio 0.21, 95% confidence interval 0.04-1.05. None of the infants in the dexamethasone group had recurrence of PDA after indomethacin therapy as compared with three infants in the placebo group. Dexamethasone significantly reduced the number of days infants required ventilator and supplemental oxygen as compared with infants who received placebo. Dexamethasone, as compared with placebo, also reduced the incidence of BPD, p = 0.025, odds ratio 0.08, 95% confidence interval 0.01-0.58. Dexamethasone may reduce the incidence of PDA in premature infants who weigh less than 1000 g at birth and thereby reduce the incidence of BPD.
