- There have been isolated instances of survival as early as 22 weeks,
- but the gestational age of the infant is always a guesstimate. With
- the usage of such interventions as high frequency ventilation, ECMO,
- synthetic surfactant, and experience, the survival rates for these
- extremly early births is rising. Unfortunately, the chances of them
- ever living a normal life is still virtually nill.
- In the real world, we *try* to save every wanted pregnancy, from week
- 20 on. But it just doesn't generally work. Perhaps 1 in 10 will
- survive, and at the cost of severe life long problems.
- There is no universally accepted definition of viability. In those
- states that have laws defining viability, 26 weeks is the date I've
- always seen.

- From a strictly pragmatic viewpoint, I'd say tha tthe survival "at
- home" definition is more accurate as far as viability goes. With the
- uproar over medical costs, it becomes necessary to ask just who is
- going to pay the bills?
