We are also considering using dextrose gel for asymptomatic neonatal hypoglycemia in our unit. I would be very interested to know if anyone has experience in their hospital pharmacy compounding the 40% dextrose gel so it could be administered preservative free. It appears that the only commercially available dextrose gels here in the U.S. contain methyl and propyl parabens as preservatives. I am curious how the New Zealand group maintains sterility of their dextrose gel over long periods of time. Do they keep it refrigerated? Anyway, the commercially available dextrose gel here in the U.S. is called glutose 15 (Paddock Laboratories, Inc.). Here is a link that outlines all of the ingredients: http://dailymed.nlm.nih.gov/dailymed/lookup.cfm?setid=ba2522af-e664-47ef-b93b-63f12fcfb1ea#nlm34071-1
