I know the time frame for viability but what is typically the lowest viable birth weight?
TIA if anyone knows
My patient this week was a previous 27 week IUGR preemie born 533g.

It depends.....the lowest I have seen was 360 gms....very severe IUGR. I've seen many different ages that were IUGR, so to put an actual number onto it would be hard. Usually, under 500 isn't viable, but like I said...depends on the circumstances.

Most NICU equipment, ETT, umbilical lines etc... drug protocols and such set a cut off of 500gms. smallest I have ever taken care of that survived weighed 400gm.

Thanks for the info!

I've always heard 500 gms

The patient I have been taking care of all week was born at 363 grams, 2 months ago.

It usually more like weight and gestation. A sever IUGR baby born @ 27 weeks, but 400 gms is considerd viable. 400 grams and 23 weeks is not viable. Follow me? When you hear about the smallest baby to survive they are usually IUGR pts.

About 7-8 weeks ago, we delivered a 25 week severe IUGR at 370 g. The baby is actually doing quite well. He had his PDA closed surgically at 5 weeks and had no complications. No brain bleeds to date. And he now weighs 2 lbs 7 oz and eating well. This is the best that I have heard of.

This is a good question to ask the NICU forum members. THEY are the experts!
(I have heard "generally" 500g, but as you see, exceptions exist!)

I forgot about the NICU forum!
