what's the earliest a baby can be born and survive?

post #1 of 24
Thread Starter 
I feel like when I get to this milestone, I can wipe a little sweat off my brow. I'm actually not that worried with this pregancy, but I like to be able to say to myself, "Ok, if the baby were born today it would probably survive, even though it would take a lot of medical intervention." Then later I can reassure myself that the baby surely live, but just have a long stay in the NICU. So...is it 25 weeks? I know I've read that almost all babies born after 28 weeks survive.

I don't have any risk factors or history of premature births, I just play these mind games with myself.

the *smallest* baby ever to survive is Rumaisa Rahma and she was 8" long and 25 weeks at birth. It was last year I think so you may remember her and her twin being on the news. According to - now I can't remember the name of the paper - 50 babies a year survive at 23 weeks.

The old "age of viability" was 27 weeks. It was set to that for a LONG time. Now (as of what, 3, 4 years ago) it went to 24 then 23 weeks. So the medical community generally considers this # of weeks to be "viable" given the most up to date medical care.

I work in antepartum, and I see premies and losses all the time.

The earliest I've seen personally survive was a 23 4/7 weeker. He's still in NICU, and probably will be for a looooong time if he makes it. His sister (twin) prolapsed a cord and didn't make it.

But then again, we have 32 and 33 (even 35) weekers who just don't make it. Not because there's something specifically wrong with them, they're just not mature and vigorous enough. (brain bleeds and necrotizing entero-colitis--where the intestinal tissue becomes infected and rots--are also a big problem for the early ones, so they might survive for a few days-weeks, but...not in the long run)

Hi Mama, How funny. I've been playing this game myself. Thinking ok, if the baby was born there's a chance, or getting to be a pretty good chance. I figured I was the only one!! :

I also don't have any risk factors or history of premature birth, but I've played this game with I think all my pregnancies!! SO just wanted to let you know you're not the only one!

When I was in the hospital delivering my 21w, 0d second son a helpful but lacking common sense NICU nurse told me, "if only you'd waited a week before going into pre-term labor, we don't even attend the birth until 22 weeks, since there's no chance of survival until then." I guess it never occurred to her that her words were more hurtful than helpful.

And, yes, I understand the OP's emotions and thoughts here. I have 5 days until this pg gets to that 22 week mark.

Not from you DDC, but I saw this and had to respond. I saw a preemie and his mom here getting pics for his passport. I asked how old and she said FOUR MONTHS. This baby was tiny!!!! I was shocked. She then told me he was born at not quite 23 weeks.

Here's his story. http://english.samsunghospital.com/h...ptCode=EngHome

Long term prognosis is that he is normal and healthy and should have no extraordinary delays as a result of his early birth.

I play the same mind games with myself! Have with each pg. I've always at least told myself that somewhere in the 30s would be viable- I am so amazed to hear that 20-something weekers can survive!

However, then my question is: at what cost? What does "survive" mean? We had a friend of the family who had a very early preemie, 25 weeks I believe, and her little boy is very challenged with a plethora of ailments. She had her little guy when I was newly pg with my DC#1, so the possibility was forefront in my mind my entire pg (as if I don't worry enough... *sigh*). So I think that's where my self-imposed 30-something weeks comes in, to have a baby survive and be healthy.

I always heard 26 weeks gave a hair of a chance and the odds increased from there.

I mentioned the 23 week milestone to DH when we hit it, and he thought I was off my rocker. You aren't alone, mama!

Well, it's good to know that I'm not the only one!

mary3mama- I can't imagine why a nurse would say something like that to you. As if you chose to have pre-term labor?! As if it's no big deal that the baby was too young to survive?!

sierratahoe- I agree. Just survival is not really what I find reassuring. I think it's knowing that there's the possibility that the baby would live and be physically and mentally healthy that I try to comfort myself with.

I'm sure CMM could tell you, survival/lack of complications are very individual. MIL's friend gave birth at 24w, son is perfectly fine, no delays. My friend gave birth at 28w, no problems. However, some people give birth much later and the child has many more problems if they survive. It just depends on the complications that arise for each individual.

Oh Mary3Mama, how awful for you to have someone say something like that as you are going through such a painful thing

This is always a milestone that I like to reach, too. I have always been told 24 weeks, but I know they are now even considering 23 weeks in the medical community. The use of surfactant for the lungs has made a big difference in how much earlier they can save the little ones. I have known several babies over the 4+ years I have been on baby boards to be born at 24-25 weeks with no lasting problems. It really is amazing!

Since I had a 29 weeker last time (he's perfectly fine with no delays, and is actually BIG for his actual age now!), I play the "baby is viable now" game too! Technically, 23 weeks is about the earliest a baby is viable, but there's still very small chance of survival at that point. I think the chance of survival is 50% at 24 weeks? There's a list of percentages somewhere on the net, and basically, each week baby stays in, it's better off, and a week can make a huge difference! There were several 25 weekers born this year on MDC, and they're doing pretty well.

My DS was born at 29w4d, but he was the size of a 31-32 weeker and did really really well - just 4 weeks in the NICU, and came home with no problems except some mild reflux that he outgrew by 6 months. But every baby is individual, and the complications they have while in the NICU can affect things. The only thing DS had going on was some mild apnea, which is normal in preemies until their nervous systems mature. And he had to learn to take oral feedings, and hold his own temp. He was breathing 100% on his own the day after birth (thank you steroids and surfectant), and within a few days, he was getting tube feedings instead of IV. So the only tubes/wires he had on him during most of his stay was the feeding tube going down his mouth/throat into his stomach, and the monitor wires that attach to chest and feet (not sticking in baby). As I said though, he did *very* well, and not all babies his age (or even older) do that well in the NICU.

Size can affect things too, including long term issues. I believe 3.5 lbs is the cutoff for the big risk of ROP (Retinopathy of Prematurity - an eye problem)? The smaller the baby, the more complications they're at risk for. So if your baby is big for gestational age, that *can* be helpful (although it doesn't always help everything).

As far as long term issues go... I've read that after 28 weeks, the chances of having a normal life with no long term developmental issues is pretty good. And IRL, I actually know several 28 weekers who have no problems whatsoever (most are high school/college age - they all came out of the woodwork when I was hospitalized for PPROM!). And the technology is better now than it was back then.

My big goals this pregnancy have been... 22 weeks without PPROM (lungs develop 18-22 weeks, and need amniotic fluid for that), 24 weeks (what I consider viability), 29 weeks (when I PPROM'd last time), 36 weeks (when my midwife can legally attend my birth out-of-hospital - what I *wanted* to do last time).

I'm 25 weeks now, and if my baby came today, I think he would probably survive, especially since he is measuring big like his brother did. But I'd feel ALOT more comfortable if he waited until the 30s, preferably at least mid-30s, so the NICU stay can be shorter (or possibly even avoid one and have a take-home baby!). But hopefully, I'll avoid the hospital altogether. Maybe I'll be posting here at 43 weeks, saying "Ok, you can come now!".

Yes, my actual goal is 36/37 weeks, when I'm clear for a homebirth!!

I like to read the blog of a neonatalogist, and he says that a 24 weeker has a 55-60% chance of survival and a 25% chance of severe delays. So the long term prognosis for a 24 weeker (caveat! one born at a hospital with a Level 3 NICU capable of providing effective treatment for a 24 weeker) is amazingly good.

Supposedly 23 weeks is THE earliest, but chances are not good.

I popped over from January DDC. I asked this question at my last appointment. The Dr. said my magic date for "viability" is September 17, which marks the beginning of my 24th week.
