This manuscript is a summary of a comprehensive report dealing with as
thma and pregnancy issued by the working group on Asthma and Pregnancy
, National Institutes of Health (NIH), National Heart, Lung, and Blood
Institute. The report was developed by a panel of obstetricians, phar
macologists, internists, allergists, and pulmonologists, who met over
an 18-month period under the auspices of the NIH. Undertreatment of pr
egnant asthmatics, partially because of unfounded fears of adverse pha
rmacologic effects on the developing fetus, remains the major problem
in the management of asthma during pregnancy in the United States. The
four key components of asthma management during pregnancy are: 1) obj
ective assessment of maternal lung function and fetal well-being, 2) a
voidance or control of environmental precipitating factors, 3) pharmac
ologic therapy, and 4) patient education.
