Committee Opinion Number 767, February 2019

(Replaces Committee Opinion Number 692, September 2017)

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...

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 require minimal interventions and have 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 to the labor unit, a process of shared decision making is recommended to create a plan for self-care activities and coping techniques. Admission during the la...

ABSTRACT: There are medical indications in pregnancy for which there is evidence or expert opinion to support delivery versus expectant management in the early-term period. However, the risk of adverse outcomes is greater for neonates delivered in the early-term period compared with neonates delivered at 39 weeks of gestation. In addition to immediate adverse perinatal outcomes, multiple studies have shown increased rates of adverse long-term infant outcomes associated with late-preterm and early-term delivery compared with full-term delivery. A recent systematic review found that late-preter...

Committee Opinion Number 764, February 2019

(Replaces Committee Opinion No. 560, April 2013)

ABSTRACT: The neonatal risks of late-preterm and early-term births are well established, and the potential neonatal complications associated with elective delivery at less than 39 0/7 weeks of gestation are well described. However, there are a number of maternal, fetal, and placental complications in which either a late-preterm or early-term delivery is warranted. The timing of delivery in such cases must balance the maternal and newborn risks of late-preterm and early-term delivery with the risks associated with further continuation of pregnancy. Deferring delivery to the 39th week is not re...

Committee Opinion Number 761, January 2019

(Replaces Committee Opinion No. 559, April 2013)

ABSTRACT: The incidence of cesarean delivery on maternal request and its contribution to the overall increase in the cesarean delivery rate are not well known, but it is estimated that 2.5% of all births in the United States are cesarean delivery on maternal request. Cesarean delivery on maternal request is not a well-recognized clinical entity. The available information that compared the risks and benefits of cesarean delivery on maternal request and planned vaginal delivery does not provide the basis for a recommendation for either mode of delivery. When a woman desires a cesarean delivery ...

ABSTRACT: Placenta accreta spectrum, formerly known as morbidly adherent placenta, refers to the range of pathologic adherence of the placenta, including placenta increta, placenta percreta, and placenta accreta. The most favored hypothesis regarding the etiology of placenta accreta spectrum is that a defect of the endometrial–myometrial interface leads to a failure of normal decidualization in the area of a uterine scar, which allows abnormally deep placental anchoring villi and trophoblast infiltration. Maternal morbidity and mortality can occur because of severe and sometimes life-threaten...

(Replaces Committee Opinion No. 234, May 2000)

ABSTRACT: This Committee Opinion is being revised to provide updated guidance on the management of pregnant women during pregnancy and delivery to prevent mother-to-child transmission of the human immunodeficiency virus (HIV). Prevention of transmission of HIV from the woman to her fetus or newborn is a major goal in the care of pregnant women infected with HIV. Continuing research into mother-to-child transmission of HIV has suggested that a substantial number of cases of perinatal HIV transmission occur as the result of fetal exposure to the virus during labor and delivery. The precise mech...

Committee Opinion Number 745, August 2018

(Replaces Committee Opinion Number 340, July 2006)

ABSTRACT: There is a trend in the United States to perform cesarean delivery for term singleton fetuses in a breech presentation. The number of practitioners with the skills and experience to perform vaginal breech delivery has decreased. The decision regarding the mode of delivery should consider patient wishes and the experience of the health care provider. Obstetrician–gynecologists and other obstetric care providers should offer external cephalic version as an alternative to planned cesarean for a woman who has a term singleton breech fetus, desires a planned vaginal delivery of a vertex-...

Committee Opinion Number 731, March 2018

ABSTRACT: Individual prenatal care is intended to prevent poor perinatal outcomes and provide education to women throughout pregnancy, childbirth, and the postpartum period through a series of one-on-one encounters between a woman and her obstetrician or other obstetric care provider. Concerns regarding increasing health care costs, health care provider availability, dissatisfaction with wait times, and the minimal opportunity for education and support associated with the individual care model have given rise to interest in alternative models of prenatal care. One alternative model, group pre...

Committee Opinion Number 726, December 2017

(Replaces Committee Opinion Number 555, March 2013)

ABSTRACT: Large-scale catastrophic events and infectious disease outbreaks highlight the need for disaster planning at all community levels. Features unique to the obstetric population (including antepartum, intrapartum, postpartum and neonatal care) warrant special consideration in the event of a disaster. Pregnancy increases the risks of untoward outcomes from various infectious diseases. Trauma during pregnancy presents anatomic and physiologic considerations that often can require increased use of resources such as higher rates of cesarean delivery. Recent evidence suggests that floods an...

(Reaffirmed 2019)

ABSTRACT: Vaginal seeding refers to the practice of inoculating a cotton gauze or a cotton swab with vaginal fluids to transfer the vaginal flora to the mouth, nose, or skin of a newborn infant. The intended purpose of vaginal seeding is to transfer maternal vaginal bacteria to the newborn. As the increase in the frequency of asthma, atopic disease, and immune disorders mirrors the increase in the rate of cesarean delivery, the theory of vaginal seeding is to allow for proper colonization of the fetal gut and, therefore, reduce the subsequent risk of asthma, atopic disease, and immune disorde...
