Committee Opinion Number 656, February 2016

(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...

ABSTRACT: The U.S. Food and Drug Administration advises against the use of magnesium sulfate injections for more than 5–7 days to stop preterm labor in pregnant women. Based on this, the drug classification was changed from Category A to Category D, and the labeling was changed to include this new warning information. However, the U.S. Food and Drug Administration’s change in classification addresses an unindicated and nonstandard use of magnesium sulfate in obstetric care. The American College of Obstetricians and Gynecologists and the Society for Maternal-Fetal Medicine continue to support ...

ABSTRACT: Physical activity in all stages of life maintains and improves cardiorespiratory fitness, reduces the risk of obesity and associated comorbidities, and results in greater longevity. Physical activity in pregnancy has minimal risks and has been shown to benefit most women, although some modification to exercise routines may be necessary because of normal anatomic and physiologic changes and fetal requirements. Women with uncomplicated pregnancies should be encouraged to engage in aerobic and strength-conditioning exercises before, during, and after pregnancy. Obstetrician–gynecologis...

ABSTRACT: Once considered a waste product that was discarded with the placenta, umbilical cord blood is now known to contain potentially life-saving hematopoietic stem cells. When used in hematopoietic stem cell transplantation, umbilical cord blood offers several distinct advantages over bone marrow or peripheral stem cells. However, umbilical cord blood collection is not part of routine obstetric care and is not medically indicated. Umbilical cord blood collection should not compromise obstetric or neonatal care or alter routine practice for the timing of umbilical cord clamping. If a patie...

Committee Opinion Number 645, November 2015

ABSTRACT: Gonorrhea is the second most commonly reported bacterial sexually transmitted disease in the United States, with an estimated 820,000 new Neisseria gonorrhoeae infections occurring each year. Antimicrobial resistance limits treatment success, heightens the risk of complications, and may facilitate the transmission of sexually transmitted infections. Neisseria gonorrhoeae has developed resistance to the sulfonamides, the tetracyclines, and penicillin. Dual therapy with ceftriaxone and azithromycin remains the only recommended first-line regimen for the treatment of gonorrhea in the U...

ABSTRACT: The Apgar score provides an accepted and convenient method for reporting the status of the newborn infant immediately after birth and the response to resuscitation if needed. The Apgar score alone cannot be considered to be evidence of or a consequence of asphyxia, does not predict individual neonatal mortality or neurologic outcome, and should not be used for that purpose. An Apgar score assigned during a resuscitation is not equivalent to a score assigned to a spontaneously breathing infant. The American Academy of Pediatrics and the American College of Obstetricians and Gynecolog...

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...

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 639, September 2015

ABSTRACT: Information from vital records is critical to identify and quantify health-related issues and to measure progress toward quality improvement and public health goals. In particular, maternal and infant mortality serve as important indicators of the nation’s health, thereby influencing policy development, funding of programs and research, and measures of health care quality. Accurate and timely documentation of births and deaths is essential to high-quality vital statistics. This Committee Opinion describes the process by which births, maternal deaths, and fetal deaths are registered;...

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....

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...

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...

ABSTRACT: Given the enormous advances in the prevention of perinatal transmission of human immunodeficiency virus (HIV), it is clear that early identification and treatment of all pregnant women with HIV is the best way to prevent neonatal infection and also improve women’s health. Furthermore, new evidence suggests that early initiation of antiretroviral therapy in the course of infection is beneficial for individuals infected with HIV and reduces the rate of sexual transmission to partners who are not infected. Screening should be performed after women have been notified that HIV screening ...

ABSTRACT: Perinatal depression, which includes major and minor depressive episodes that occur during pregnancy or in the first 12 months after delivery, is one of the most common medical complications during pregnancy and the postpartum period, affecting one in seven women. It is important to identify pregnant and postpartum women with depression because untreated perinatal depression and other mood disorders can have devastating effects on women, infants, and families. Several screening instruments have been validated for use during pregnancy and the postpartum period. Although definitive ev...

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.

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...

ABSTRACT: The main goal of ovarian reserve testing is to identify those individuals who are at risk of decreased or diminished ovarian reserve, commonly known as DOR. Although ovarian reserve testing cannot predict the end of one’s reproductive years, results outside the range expected for a patient’s age can encourage the individual to pursue more aggressive treatment options to achieve pregnancy. Ovarian reserve testing should be performed for women older than 35 years who have not conceived after 6 months of attempting pregnancy and women at higher risk of diminished ovarian reserve. When ...

ABSTRACT: Accurate dating of pregnancy is important to improve outcomes and is a research and public health imperative. As soon as data from the last menstrual period, the first accurate ultrasound examination, or both are obtained, the gestational age and the estimated due date should be determined, discussed with the patient, and documented clearly in the medical record. Subsequent changes to the estimated due date should be reserved for rare circumstances, discussed with the patient, and documented clearly in the medical record. When determined from the methods outlined in this document fo...

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 597, May 2014

(Reaffirmed 2016)

Abstract: Functional oxytocin deficiency and a faulty oxytocin signaling pathway have been observed in conjunction with autism spectrum disorder (ASD). Because exogenous synthetic oxytocin commonly is administered for labor induction and augmentation, some have hypothesized that synthetic oxytocin used for these purposes may alter fetal oxytocin receptors and predispose exposed offspring to ASD. However, current evidence does not identify a causal relationship between labor induction or augmentation in general, or oxytocin labor induction specifically, and autism or ASD. Recognizing the limit...
