Blood sugar guidelines for neonates

What are your guidelines for hypoglycemia in newborns? I am at a new facility and the neonatologist is insisting that after day 2, the blood sugar needs to be between 60 and 70. The policy is above 50 first day of life. In my old facility, the policy was above 40 first day of life and then above 50 after that. This physician says that the current evidence says the blood sugar has to be above 60 and that the Academy of Pediatrics and breastfeeding medicine has it wrong. What is your practice and is there new evidence to support a BS over 60? I'm getting frustrated when trying to support my breastfeeding families.

Do you routinely check blood sugars on all babies for 2 days? When I worked in mother/baby, only babies of diabetic moms or LGA babies were on a glucose check series, which was at 1, 2, 4, 6, 12, and 24 hours of life. We didn't continue after that and we didn't check blood sugars on the rest of the babies at all, unless they looked jittery. I'm doubtful of this pediatrician's claims, I haven't heard of any recent evidence supporting him/her.

We do the same for our babies. Newborns born to either GDM or type 2 diabetes and symptomatic newborns. I think he is making it up. Unfortunately, he runs the show and obviously does not trust breastfeeding.

That's so frustrating, and unfortunately common. The job I had on the mother/baby unit was at a recently-certified Baby Friendly hospital, and the pediatricians were actually some of our biggest roadblocks to getting certified, with very outdated/incorrect knowledge about breastfeeding. Where I work now as a midwife we are "trying" to go BF, and again, peds continues to insist that formula is necessary way more than it is clinically indicated by current evidence. :-(

I'd ask the pediatrician for the research paper he is basing his orders on.

I'd also make sure that there was a hospital policy in place based on best evidence regarding how often blood sugars are checked, what the acceptable parameters are, and what interventions are required.

I am in the process of doing that. I'm used to a more collegial atmosphere, physicians and nurses working together. Thanks for all of the responses. I am afraid I have a long uphill battle.

Both the American Academy of Pediatrics and the Canadian Paediatric Society have guidelines regarding serum glucose screening of newborns, both of which are available on line at no charge:

At my hospital, preterm and SGA babies are tested q2-3 hr for 24 hrs, and LGA babies and those born to type 1, 2 or GDM moms are tested q2-3 hr for 12 hrs. The last three blood sugars have to be above 45.

Our standing orders are to check glucose for 4000g regardless of gestation, anyone 45.

Our neos like sugars to be >60 after 24 hours, but the reality is we don't check too many sugars at that point.

When I took STABLE earlier this year (great class btw, highly recommend it), the NNP teaching it told us general consensus is that there is no general consensus for a certain number that is best for every infant. We probably miss asymptomatic hypoglycemia because we don't check every newborn randomly....but the babies are apparently fine. And some kids will crash no matter what you feed them but there is almost always something else behind it when that happens.

I feel like I'm another planet. One particular MD is in the wrong century. I'm so frustrated trying to support breastfeeding with such outdated practice. Thanks for the info. At least I know I'm not crazy.

I've seen many breastfeeding relationships be damaged with ridiculous blood sugar protocols. This is one of my hulksmash issues. grrrr.
