Committee Opinion Number 443, October 2009

(Replaces No. 264, December 2001, Reaffirmed 2016)

ABSTRACT: In the absence of obstetric or medical complications, pregnant women can observe the same precautions for air travel as the general population and can fly safely. Pregnant women should be instructed to continuously use their seat belts while seated, as should all air travelers. Pregnant air travelers may take precautions to ease in-flight discomfort and, although no hard evidence exists, preventive measures can be used to minimize risks of venous thrombosis. For most air travelers, the risks to the fetus from exposure to cosmic radiation are negligible. For pregnant aircrew members ...


Committee Opinion Number 496, August 2011

(Reaffirmed 2013)

ABSTRACT: Compared with men, at-risk alcohol use by women has a disproportionate effect on their health and lives, including reproductive function and pregnancy outcomes. Obstetrician–gynecologists have a key role in screening and providing brief intervention, patient education, and treatment referral for their patients who drink alcohol at risk levels. For women who are not physically addicted to alcohol, tools such as brief intervention and motivational interviewing can be used effectively by the clinician and incorporated into an office visit. For pregnant women and those at risk of pregna...

ABSTRACT: Noninvasive prenatal screening that uses cell-free DNA from the plasma of pregnant women offers tremendous potential as a screening method for fetal aneuploidy. A number of laboratories have validated different techniques for the use of cell-free DNA as a screening test for fetal aneuploidy. All tests have a high sensitivity and specificity for trisomy 18 and trisomy 21, regardless of which molecular technique is used. Women whose results are not reported, indeterminate, or uninterpretable (a “no call” test result) from cell-free DNA screening should receive further genetic counseli...

Committee Opinion Number 579, November 2013

Reaffirmed 2015

ABSTRACT: In the past, the period from 3 weeks before until 2 weeks after the estimated date of delivery was considered “term,” with the expectation that neonatal outcomes from deliveries in this interval were uniform and good. Increasingly, however, research has shown that neonatal outcomes, especially respiratory morbidity, vary depending on the timing of delivery within this 5-week gestational age range. To address this lack of uniformity, a work group was convened in late 2012, which recommended that the label “term” be replaced with the designations early term (37 0/7 weeks of gestation ...

(Reaffirmed 2016. Replaces Committee Opinion Number 514, December 2011)

ABSTRACT: Acute-onset, severe systolic hypertension; severe diastolic hypertension; or both can occur in pregnant women or women in the postpartum period. Introducing standardized, evidence-based clinical guidelines for the management of patients with preeclampsia and eclampsia has been demonstrated to reduce the incidence of adverse maternal outcomes. Individuals and institutions should have mechanisms in place to initiate the prompt administration of medication when a patient presents with a hypertensive emergency. Once the hypertensive emergency is treated, a complete and detailed evaluati...


Committee Opinion Number 563, May 2013

(Reaffirmed 2016)

ABSTRACT: Pregnant women traditionally have been assigned priority in the allocation of prevention and treatment resources during outbreaks of influenza because of their increased risk of morbidity and mortality. The Committee on Ethics of the American College of Obstetricians and Gynecologists explores ethical justifications for assigning priority for prevention and treatment resources to pregnant women during an influenza pandemic, makes recommendations to incorporate ethical issues in pandemic influenza planning concerning pregnant women, and calls for pandemic preparedness efforts to incl...


Committee Opinion Number 660, March 2016

(Replaces Committee Opinion No. 397, February 2008)

ABSTRACT: Gestational surrogacy is an increasingly common form of family building that can allow individuals or a couple to become parents despite circumstances in which carrying a pregnancy is biologically impossible or medically contraindicated. The practice of gestational surrogacy involves a woman known as a gestational carrier who agrees to bear a genetically unrelated child with the help of assisted reproductive technologies for an individual or couple who intend(s) to be the legal and rearing parent(s), referred to as the intended parent(s). Obstetrician–gynecologists may become involv...


Committee Opinion Number 478, March 2011

(Reaffirmed 2015)

ABSTRACT: Family history plays a critical role in assessing the risk of inherited medical conditions and single gene disorders. Several methods have been established to obtain family medical histories, including the family history questionnaire or checklist and the pedigree. The screening tool selected should be tailored to the practice setting and patient population. It is recommended that all women receive a family history evaluation as a screening tool for inherited risk. Family history information should be reviewed and updated regularly, especially when there are significant changes to f...


Committee Opinion Number 638, September 2015

ABSTRACT: Hypertensive disorders with adverse sequelae (including preterm birth, maternal morbidity and mortality, and long-term risk of maternal cardiovascular disease) complicate 5–10% of pregnancies. Early identification of pregnant women at risk of developing early-onset preeclampsia would theoretically allow referral for more intensive surveillance or application of preventive therapies to reduce the risk of severe disease. In practice, however, the effectiveness of such triage would be hindered by the low positive predictive value for early-onset preeclampsia reported in the literature....

(Replaces Committee Opinion Number 299, September 2004)

ABSTRACT: Imaging studies are important adjuncts in the diagnostic evaluation of acute and chronic conditions. However, confusion about the safety of these modalities for pregnant and lactating women and their infants often results in unnecessary avoidance of useful diagnostic tests or the unnecessary interruption of breastfeeding. Ultrasonography and magnetic resonance imaging are not associated with risk and are the imaging techniques of choice for the pregnant patient, but they should be used prudently and only when use is expected to answer a relevant clinical question or otherwise provid...


Committee Opinion Number 511, November 2011

Reaffirmed 2016

ABSTRACT: Clinicians who provide care for incarcerated women should be aware of the special health care needs of pregnant incarcerated women and the specific issues related to the use of restraints during pregnancy and the postpartum period. The use of restraints on pregnant incarcerated women and adolescents may not only compromise health care but is demeaning and rarely necessary.

(Replaces Committee Opinion Number 425, January 2009)

ABSTRACT: Unauthorized (undocumented) immigrants are less likely than other residents of the United States to have health insurance. The American College of Obstetricians and Gynecologists has long supported a basic health care package for all women living within the United States without regard to their country of origin or documentation. Providing access to quality health care for unauthorized immigrants and their children, who often were born in the United States and have U.S. citizenship, is essential to improving the nation’s public health.


Committee Opinion Number 667, July 2016

ABSTRACT: Emergency departments typically have structured triage guidelines for health care providers encountering the diverse cases that may present to their units. Such guidelines aid in determining which patients must be evaluated promptly and which may wait safely, and aid in determining anticipated use of resources. Although labor and delivery units frequently serve as emergency units for pregnant women, the appropriate structure, location, timing, and timeliness for hospital-based triage evaluations of obstetric patients are not always clear. Hospital-based obstetric units are urged to ...


Committee Opinion Number 643, October 2015

ABSTRACT: Advances in the understanding of genetic conditions, reproductive technologies, and improved medical and surgical care have enabled an increasing number of women with genetic conditions to achieve a normal pregnancy outcome. However, management of certain genetic conditions during pregnancy is complex and may require a multidisciplinary approach from preconception through the postpartum period. Patients with certain genetic conditions, or those at risk of having a particular genetic condition, should have a preconception evaluation with their obstetrician–gynecologists, genetics spe...

(Reaffirmed 2016. Replaces Committee Opinion Number 468, October 2010)

ABSTRACT: The Centers for Disease Control and Prevention’s Advisory Committee on Immunization Practices and the American College of Obstetricians and Gynecologists recommend that all adults receive an annual influenza vaccine. Influenza vaccination is an essential element of preconception, prenatal, and postpartum care because pregnant women are at an increased risk of serious illness due to seasonal and pandemic influenza. Since 2010, influenza vaccination rates among pregnant women have increased but still need significant improvement. It is particularly important that women who are or will...


Committee Opinion Number 661, April 2016

ABSTRACT: Immunization against vaccine-preventable diseases is an essential component of women’s primary and preventive health care. Despite the importance of vaccination and clear guidance from public health agencies, rates of vaccination lag behind national goals. Obstetrician–gynecologists can play a major role in reducing morbidity and mortality from a range of vaccine-preventable diseases, including pertussis, influenza, human papillomavirus, and hepatitis. Given demonstrated vaccine efficacy and safety, and the large potential for prevention of many infectious diseases that affect adult...

Committee Opinion Number 518, February 2012

ABSTRACT: Intimate partner violence (IPV) is a significant yet preventable public health problem that affects millions of women regardless of age, economic status, race, religion, ethnicity, sexual orientation, or educational background. Individuals who are subjected to IPV may have lifelong consequences, including emotional trauma, lasting physical impairment, chronic health problems, and even death. Although women of all ages may experience IPV, it is most prevalent among women of reproductive age and contributes to gynecologic disorders, pregnancy complications, unintended pregnancy, and s...

Abstract: Prenatal lead exposure has known adverse effects on maternal health and infant outcomes across a wide range of maternal blood lead levels. Adverse effects of lead exposure are being identified at lower levels of exposure than previously recognized in both children and adults. In 2010, the Centers for Disease Control and Prevention issued the first guidelines regarding the screening and management of pregnant and lactating women who have been exposed to lead.


Committee Opinion Number 636, June 2015

(Replaces Committee Opinion Number 449, December 2009)

ABSTRACT: Phenylketonuria (PKU) is an autosomal recessive disorder of phenylalanine (Phe) metabolism characterized by deficient activity of the hepatic enzyme, phenylalanine hydroxylase. Increased blood Phe levels are toxic to a variety of tissues, particularly the developing fetal brain. The mainstay of treatment for PKU is the dietary restriction of Phe, which results in decreased blood Phe levels. Lifelong dietary restriction and therapy improves quality of life in patients with PKU and should be encouraged. Genetic counseling is recommended for all reproductive-aged women with PKU, and sh...


Committee Opinion Number 637, July 2015

ABSTRACT: Cannabis sativa (marijuana) is the illicit drug most commonly used during pregnancy. The self-reported prevalence of marijuana use during pregnancy ranges from 2% to 5% in most studies. A growing number of states are legalizing marijuana for medicinal or recreational purposes, and its use by pregnant women could increase even further as a result. Because of concerns regarding impaired neurodevelopment, as well as maternal and fetal exposure to the adverse effects of smoking, women who are pregnant or contemplating pregnancy should be encouraged to discontinue marijuana use. Obstetri...
