Hello Deann,
Just before sending this message, I read Susan's contribution to this
discussion and am, as always, impressed by her knowledge and analytic
capacities. Thank you, Susan! ;o)
As for the stomach capacity: at GOLD11 Nils Bergman came up with a
hypothesis about newborn stomach capacity, based on intra-stomach pressure
being measured in adults.
A certain pressure (with air, if I remember well) was brought in and raised
until becoming either uncomfortable or painful.
To find out more, this ought to be replicated in the newborn with a little
balloon at the end of a nasogastric tube, taking the pressure limits as
criterium.
From this, stomach capacity turned out to be something like 20 cc after a
week.
He discerned between functional capacity (no increase in stomach size),
physiological capacity (some increase but comfortable), receptive capacity
(what the stomach can hold at maximum stretch) and ingestive capacity (what
baby swallows, but then part will be spit out again, reflux therefore being
a capacity issue and not a disease!!).
Part of what he stated was derived from this study (Zangen S et al 2001,
Rapid Maturation of Gastric Relaxation in Newborn Infants), but it was not
done correctly, according to his opinion.
I don't have all the details, but maybe you can start working from here...?
By the way... he came to the conclusion that the feeding frequency should be
*every hour*, so that would make 60cc in 3 hours, but in portions of 20cc
per hour.
This adds up to what we consider fairly 'normal', some 480cc after a week,
but then taking the stomach capacity into account. Very interesting thought.
Best regards,

Subject: Searching for: Medical Article reflecting newborn stomach volumes
Hello all,
I am looking for a medical article, preferably physician written and NOT
associated with lactation, that details the size and volume capacity of a
newborn stomach the first few days of life. Similar to the teaching tool
from Ameda "Belly Balls" but, again, seperate from lactation. And,
preferably written within the last 5-10 years.
I have been looking myself, but am having great difficulty finding anything
relating to term newborns.
Thanks much.
