BackgroundNeonatal hypoglycemia is common and a preventable cause of brain damage.Dextrose gel is used to reverse hypoglycemia in diabetics. However, there is little evidence for its use in babies.
MethodWe enrolled 514 babies 35 to 42 weeks' gestation, < 48 hours, and at risk of hypoglycemia, to a randomized, double-blind placebo controlled trial to determine whether 40% dextrose gel massaged into the buccal mucosa is more effective than feeding alone in reversing hypoglycemia. Hypoglycemic babies were randomized to 40% dextrose gel 200 mg/kg (n= 118) or placebo (n= 119) and encouraged to feed.Primary outcome was treatment failure (blood glucose concentration <2路6 mmol/L) after two treatment attempts.
FindingsDextrose gel reduced the frequency of treatment failure (16/118 (14%) in dextrose vs. 29/119 (24%) in placebo group, RR 0路57; 95% CI 0路33 to 0路98; p=0路04). Babies receiving dextrose gel were less likely to be admitted to intensive care for hypoglycemia, (16/118 (14%) vs. 30/119 (25%); RR 0.54 (0.31, 0.93); P=0.03), to receive formula feeds (median 7 vs. 10 feeds; median difference 2; 95% CI 0 to 4; p=0路04) and to be formula fed at two weeks (5/118 (4%) vs.15/119 (13%), RR 0路34; 95% CI 0路13 to 0路90; p=0路03).

InterpretationDextrose gel should be considered for first-line treatment for management of hypoglycemia in late preterm and term babies in the first 48 hours after birth.
