Re: flyingFrom: ainsron@msn.comWed Jan 10 09:31:25 2001
Per "Occupational and evironmental Reproductive Hazards," by Maureen Paul: "the effects of high altitude on pregnancy are clearer than they are for fertility. While acute exposure to altitude during pregnancy is apparently benign, chronic exposure is associated with decreased fetal growth." As Zach stated, this is based on studies from Peru, also from Colorado, both showing decreased fetal growth after 30 wks. There was however, no increase in perinatal morbidity or mortality. With supplemental O2 in flight and/or a pressurized cabin, effects should be minimal. Avoidance of altitudes over 15,000 is suggested because no data exists. If she were my patient or wife and alternatives exist, I would advise such during pregnancy. 9 months is not forever!

The American Medical Association is no longer designating CME hours for AMA Category II CME credit. However, physicians themselves may self designate learning activities as Category II CME credit hours if they feel it is of sufficient educational merit and meets the formal definitions of continuing medical education. OBGYN.net believes these interaction in this forum meets these criteria. For further information see the AMA web site.
