Committee Opinion Number 696, April 2017

(Replaces Committee Opinion Number 474, February 2011)

ABSTRACT: The American College of Obstetricians and Gynecologists' Committee on Obstetric Practice acknowledges that the issue of nonobstetric surgery during pregnancy is an important concern for physicians who care for women. It is important for a physician to obtain an obstetric consultation before performing nonobstetric surgery and some invasive procedures (eg, cardiac catheterization or colonoscopy) because obstetricians are uniquely qualified to discuss aspects of maternal physiology and anatomy that may affect intraoperative maternal–fetal well-being. Ultimately, each case warrants a t...


Committee Opinion Number 693, April 2017

ABSTRACT: Given the increasing availability and complexity of genetic testing, it is imperative that the practicing obstetrician–gynecologist or other health care provider has a firm comprehension of the benefits, limitations, and risks of offering a specific genetic test, as well as the importance of appropriate pretest and posttest counseling. The purpose of this Committee Opinion is to provide an outline of how obstetrician–gynecologists and other health care providers can best incorporate these tests into their current practices and provide appropriate pretest and posttest counseling to p...


Committee Opinion Number 692, April 2017

(Replaces Committee Opinion No. 623, February 2015)

ABSTRACT: Acute-onset, severe systolic hypertension; severe diastolic hypertension; or both can occur during the prenatal, intrapartum, or postpartum periods. Pregnant women or women in the postpartum period with acute-onset, severe systolic hypertension; severe diastolic hypertension; or both require urgent antihypertensive therapy. 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...


Committee Opinion Number 690, March 2017

ABSTRACT: Carrier screening, whether targeted or expanded, allows individuals to consider their range of reproductive options. Ultimately, the goal of genetic screening is to provide individuals with meaningful information that they can use to guide pregnancy planning based on their personal values. Ethnic-specific, panethnic, and expanded carrier screening are acceptable strategies for prepregnancy and prenatal carrier screening. Because all of these are acceptable strategies, each obstetrician–gynecologist or other health care provider or practice should establish a standard approach that i...


Committee Opinion Number 688, March 2017

ABSTRACT: The American College of Obstetricians and Gynecologists considers first-trimester ultrasonography to be the most accurate method to establish or confirm gestational age. Pregnancies without an ultrasonographic examination confirming or revising the estimated due date before 22 0/7 weeks of gestation should be considered suboptimally dated. This document provides guidance for managing pregnancies in which the best clinical estimate of gestational age is suboptimal. There is no role for elective delivery in a woman with a suboptimally dated pregnancy. Although guidelines for indicated...


Committee Opinion Number 687, February 2017

ABSTRACT: Obstetrician–gynecologists, in collaboration with midwives, nurses, patients, and those who support them in labor, can help women meet their goals for labor and birth by using techniques that are associated with minimal interventions and high rates of patient satisfaction. Many common obstetric practices are of limited or uncertain benefit for low-risk women in spontaneous labor. For women who are in latent labor and are not admitted, a process of shared decision making is recommended. Admission during the latent phase of labor may be necessary for a variety of reasons. A pregnant w...


Committee Opinion Number 684, January 2017

(Replaces Committee Opinion Number 543, December 2012)

ABSTRACT: Delayed umbilical cord clamping appears to be beneficial for term and preterm infants. In term infants, delayed umbilical cord clamping increases hemoglobin levels at birth and improves iron stores in the first several months of life, which may have a favorable effect on developmental outcomes. There is a small increase in jaundice that requires phototherapy in this group of infants. Consequently, health care providers adopting delayed umbilical cord clamping in term infants should ensure that mechanisms are in place to monitor for and treat neonatal jaundice. In preterm infants, de...


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 652, January 2016

(Reaffirmed 2016. Replaces Committee Opinion Number 573, September 2013)

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 ...


Committee Opinion Number 650, December 2015

(Replaces Committee Opinion Number 267, January 2002)

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...


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...


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....


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...

(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 611, October 2014

(Reaffirmed 2016. See also Committee Opinion No. 579)

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...

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 ...


Committee Opinion Number 555, March 2013

(Reaffirmed 2016)

ABSTRACT: Numerous occurrences in the past decade have brought the issue of disaster preparedness, and specifically hospital preparedness, to the national forefront. Much of the work in this area has focused on large hospital system preparedness for various disaster scenarios. Many unique features of the obstetric population warrant additional consideration in order to optimize the care received by expectant mothers and their fetuses or newborns in the face of future natural or biologic disasters.


Committee Opinion Number 550, January 2013

(Reaffirmed 2016)

ABSTRACT: Myelomeningocele, the most severe form of spina bifida, occurs in approximately 1 in 1,500 births in the United States. Fetuses in whom myelomeningocele is diagnosed typically are delivered at term and are treated in the early neonatal period. A recent randomized controlled trial found that fetal surgery for myelomeningocele improved a number of important outcomes, but also was associated with maternal and fetal risks. Maternal–fetal surgery is a major procedure for the woman and her fetus, and it has significant implications and complications that occur acutely, postoperatively, fo...

Committee Opinion Number 548, January 2013

(Reaffirmed 2016)

ABSTRACT: The updated guidelines by the Institute of Medicine regarding gestational weight gain provide clinicians with a basis for practice. Health care providers who care for pregnant women should determine a woman’s body mass index at the initial prenatal visit and counsel her regarding the benefits of appropriate weight gain, nutrition and exercise, and, especially, the need to limit excessive weight gain to achieve best pregnancy outcomes. Individualized care and clinical judgment are necessary in the management of the overweight or obese woman who is gaining (or wishes to gain) less wei...


Committee Opinion Number 533, August 2012

(Reaffirmed 2016)

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.
