Committee Opinion Number 746, August 2018

(Replaces Committee Opinion Number 443, October 2009)

ABSTRACT: In the absence of obstetric or medical complications, occasional air travel is safe for pregnant women. Pregnant women can fly safely, observing the same precautions for air travel as the general population. Because severe air turbulence cannot be predicted and the subsequent risk for trauma is significant should this occur, pregnant women should be instructed to use their seat belts continuously while seated. Despite a lack of evidence associating lower extremity edema and venous thrombotic events with air travel during pregnancy, certain preventive measures can be used to minimize...


Committee Opinion Number 720, September 2017

(Replaces Committee Opinion Number 550, January 2013)

ABSTRACT: Myelomeningocele, a severe form of spina bifida, occurs in approximately 1 in 3,000 live births in the United States. The extent of disability is generally related to the level of the myelomeningocele defect, with a higher upper level of lesion generally corresponding to greater deficits. Open maternal–fetal surgery for myelomeningocele repair is a major procedure for the woman and her affected fetus. Although there is demonstrated potential for fetal and pediatric benefit, there are significant maternal implications and complications that may occur acutely, postoperatively, for the...


Committee Opinion Number 717, September 2017

(Replaces Committee Opinion 494, June 2011)

ABSTRACT: The evidence regarding an association between the nitrofuran and sulfonamide classes of antibiotics and birth defects is mixed. As with all patients, antibiotics should be prescribed for pregnant women only for appropriate indications and for the shortest effective duration. During the second and third trimesters, sulfonamides and nitrofurantoins may continue to be used as first-line agents for the treatment and prevention of urinary tract infections and other infections caused by susceptible organisms. Prescribing sulfonamides or nitrofurantoin in the first trimester is still consi...


Committee Opinion Number 278, November 2002

Reaffirmed 2017

ABSTRACT: Clinically significant false-positive human chorionic gonadotropin (hCG) test results are rare. However, some individuals have circulating factors in their serum (eg, heterophilic antibodies or nonactive forms of hCG) that interact with the hCG antibody and cause unusual or unexpected test results. False-positive and false-negative test results can occur with any specimen, and caution should be exercised when clinical findings and laboratory results are discordant. Methods to rule out the presence of interfering substances include using a urine test, rerunning the assay with serial ...
