Debra, >Since this group also has the attention span of a gnat, Thank you for my chuckle of the day. That does seem to describe it, doesn't it? The question becomes, do the inhaled anesthetics cross over into breastmilk, and does it have an effect on the baby if he drinks the breastmilk which will go into his GI tract? How long are the metabolites of general anesthesia present in the milk? Has anyone ever tested milk for nitrous oxide or fluothane or whatever? My husband-the-pharmacist is of the studied opinion that once the mother is awake & aware, the anesthetic is gone too. How long can it last in the system since they have to keep giving it to her during surgery? Dr. Tom -- we await your opinion.... Jan B
