Air
travel is safe for most pregnant women up to 36 weeks gestation, according
to a new committee opinion issued by The American College of Obstetricians
& Gynecologists (ACOG). In the absence of obstetric or medical complications,
pregnant women can observe the same basic precautions for air travel as
the general population does, notes ACOG.
Most US airlines allow pregnant women to fly up to 36 weeks gestation
on domestic flights. For international flights, 35 weeks gestation is
usually the limit.
While travel in an airplane is almost always safe during pregnancy, the
document does address some instances in which air travel should be
avoided.
Travel is not recommended at any time during pregnancy for women who
have either medical or obstetric complications -- such as pregnancy-induced
hypertension, poorly controlled diabetes, or sickle cell disease --
that could result in an unforeseen emergency.
ACOG also advises against air travel by pregnant women at significant
risk for premature labor or with placental abnormalities.
According to ACOG, environmental conditions associated with flying, such
as low cabin humidity and changes in cabin pressure, may result in an
increased heart rate, increased blood pressure and a significant decrease
in breathing capabilities in pregnant women with a weakened cardiovascular
system.
One issue of concern for all air travelers is the formation of blood
clots, especially during longer flights.
Pregnant women, as well as all air travelers, may take special precautions
to minimize risks, such as wearing support stockings and periodically
moving the lower legs to allow for proper blood circulation.
To ease in-flight discomfort, pregnant women should avoid gaseous
foods and drinks before flying.
Because air turbulence cannot be predicted and the risk for trauma is
significant, continuous use of seat belts while seated is highly
recommended.
