New-born babies can suffer from low blood sugar (hypoglycaemia) which can increase a baby’s risk of brain damage or developmental delay. Usually babies with low blood sugar are helped by having extra feeding with formula milk or being admitted to a neonatal intensive care unit (NICU) and being given dextrose injections. In this study researchers in New Zealand tried using dextrose gel which could be massaged into babies’ cheeks. 416 babies were included in the trial. Some received the dextrose gel while others received a placebo. The babies who were given the dextrose gel were less likely to suffer from low blood sugar and were less likely to be admitted to hospital suffering from it.
