Previous message: R. Daniel Braun: "Re: Pregnancy At Altitude" In reply to: Joe: "Re: Pregnancy At Altitude" Occupational and environmental reproductive hazards, by Paul states: "Commercial air travel and acute exposure to altitudes less than 15,000 ft pose no adverse on maternal or fetal well-being. Pregnant women with medical problems (anemia, sickle cell, cardiac problems, etc.) that might be exacerbated by hypoxic environments should be carefully counseled. Avoidance of high altitudes us use of supplemental oxygen during flight may be necessary for these women." It differentiates between acute and chronic exposure, pointing out that IUGR is related to babies born above 10,000 feet, according to a study of Colorado women who lived above that altitude. Acute changes of altitude during flight do not appear to have an adverse effect on pregnancy outcome, studies of exposure to commercial jet travel with cabin pressures comparable to 8000 ft show small increases in maternal HR and no change in BP. Fetal monitoring during flight have shown no changes in FHR or variability. Ronald E.

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.
