Print The Case A year-old woman, gravida 3, para 1, presented for prenatal care at 24 weeks. Her past medical history was unremarkable, and results of her prenatal laboratory tests were normal. On physical examination, she was moderately obese and had a fundal height of 24 cm. Fetal heart tones were about per minute. Routine prenatal care was planned. The patient missed several ultrasound appointments, but did have several additional prenatal physical examinations that indicated normal growth in fundal height, up to a week size. At 42 weeks, she was admitted for post-dates labor induction using misoprostol and oxytocin. Twelve hours into the induction, examination showed 3 cm cervical dilatation.

In , the overall incidence of postterm pregnancy in the United States was 5. The incidence of postterm pregnancies may vary by population, in part as a result of differences in regional management practices for pregnancies that go beyond the estimated date of delivery. Accurate determination of gestational age is essential to accurate diagnosis and appropriate management of late-term and postterm pregnancies.
Antepartum fetal surveillance and induction of labor have been evaluated as strategies to decrease the risks of perinatal morbidity and mortality associated with late-term and postterm pregnancies. The purpose of this document is to review the current understanding of late-term and post-term pregnancies and provide guidelines for management that have been validated by appropriately conducted outcome-based research when available.

The information should not be construed as dictating an exclusive course of treatment or procedure to be followed. The American College of Obstetricians and Gynecologists considers first-trimester ultrasonography to be the most accurate method to establish or confirm gestational age.
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 late-preterm and early-term deliveries depend on accurate determination of gestational age, women with suboptimally dated pregnancies should be managed according to these same guidelines because of the lack of a superior alternative.
The best clinical estimate of gestational age should serve as the basis for decisions regarding antenatal corticosteroid exposure in women with suboptimally dated pregnancies who are at perceived risk of preterm delivery.
Premature or Overdue
With that in mind, one must look at prenatal care in the context of risk assessment, health promotion, and risk-directed intervention in general and not just from an obstetrical perspective. This means that a large range of issues must be systematically and consistently addressed and documented during prenatal care. If one were to attempt to make an analogy between prenatal care and building a house, the prenatal record might be seen as the blueprint and checklist for construction, and the initial prenatal visit as the foundation and framework on which the rest of the structure is built.
Good prenatal care depends on many factors but clearly is facilitated by a good prenatal record. Additionally, the prenatal record both guides and documents the delivery of good prenatal care.

Aetna considers detailed ultrasound fetal anatomic examination experimental and investigational for all other indications including routine evaluation of pregnant women who are on bupropion Wellbutrin or levetiracetam Keppra , pregnant women with low pregnancy-associated plasma protein A, and pregnant women who smoke or abuse cannabis. There is inadequate evidence of the clinical utility of detailed ultrasound fetal anatomic examination for indications other than evaluation of suspected fetal anatomic abnormalities.
Detailed ultrasound fetal anatomic examination is not considered medically necessary for routine screening of normal pregnancy, or in the setting of maternal idiopathic pulmonary hemosiderosis.

Deciding which is the appropriate management is based on assessment of symptoms, ultrasound findings, menopausal status, RMI if applicable and risk factors. An approach to management is outlined in Figure 1. These simple cysts will resolve within three menstrual cycles. If surgery is required, a laparoscopic cystectomy is the operation of choice, as aspiration can cause recurrence. Cysts of 2—5 cm should be rescanned in 3—4 months. In addition, any woman who does not meet the criteria for conservative management should be offered surgical management.
If malignancy is suspected, an oophorectomy is recommended rather than a cystectomy.

Received Aug 17; Accepted Jan For permissions, please e-mail: This article has been cited by other articles in PMC. Multivariable linear regression was conducted to determine the extent to which ultrasound GA predicted LMP dating and to correct for systematic misclassification that results after applying standard guidelines to adjudicate differences in these measures.
With adjustment for maternal age, smoking, and first-trimester vaginal bleeding, standard guidelines for adjudicating differences in ultrasound and LMP dating underestimated SGA birth by This methodological approach can be applied by researchers using different study populations in similar research contexts. Errors in estimating GA can result in misclassification, limiting progress towards identifying vulnerable times of fetal exposure and strategies to prevent adverse pregnancy outcomes.
The most widely available approaches for estimating the duration of gestation are last menstrual period LMP dating i. The shortcomings of LMP dating include inaccurate recall, the assumption that all menstrual cycles last 28 days, and the possibility of mistaking vaginal bleeding early in pregnancy as a menstrual period 1 — 3.

Definition Labor is a physiologic process during which the products of conception ie, the fetus, membranes, umbilical cord, and placenta are expelled outside of the uterus. Labor is achieved with changes in the biochemical connective tissue and with gradual effacement and dilatation of the uterine cervix as a result of rhythmic uterine contractions of sufficient frequency, intensity, and duration.
The onset of labor is defined as regular, painful uterine contractions resulting in progressive cervical effacement and dilatation. Cervical dilatation in the absence of uterine contraction suggests cervical insufficiency, whereas uterine contraction without cervical change does not meet the definition of labor. Previous Stages of Labor and Epidemiology Stages of Labor Obstetricians have divided labor into 3 stages that delineate milestones in a continuous process.

A maximum vertical pocket of centimeters is normal Doppler scan As indicated Not recommended without an indication e. Am J Obstet Gynecol ; 5: Nutrition A woman carrying twins has unique nutritional needs, especially for additional calories. Because the patient most often experiences early satiety and loss of appetite, we recommend a consult with a nutritionist to address this and other issues.
She must increase her daily dietary intake by about calories per day, calories more than a woman carrying a singleton gestation. High-protein shakes are recommended given the high nutritional value. Because women carrying twins are at an increased risk of developing anemia, the Society of Maternal-Fetal Medicine recommends 30 milligrams of iron during the first trimester and 60 milligrams of iron until delivery.
The Society of Maternal-Fetal Medicine also recommends that they take 1 mg of folic acid to prevent neural tube defects most prenatal vitamins have 0. For dizygotic twins, there is a higher probability that one or more of the fetuses will have a trisomy, resulting in a higher overall risk to the pregnancy. We recommend that all women carrying twins have integrated serum screening with a first trimester nuchal translucency measurement. Invasive diagnostic testing with chorionic villus sampling CVS or amniocentesis are available options.
However, understanding the higher risk of false positives and false negatives associated with the use of cell-free fetal DNA in twin pregnancies, this test can be offered to patients who are over the age of 33 or 35 depending on the kind of twins. The incidence of congenital anomalies is fold higher in monozygotic twins than in singletons or dizygotic twins; thus, we stress the importance of an early anatomy ultrasound.

Aetna considers the endometrial brush Tao brush an acceptable alternative to an endometrial suction curette e. Aetna considers the following experimental and investigational because the effectiveness of these approaches has not been established: Background The National Cancer Institute NCI, has stated that there is insufficient evidence to establish whether a decrease in mortality from endometrial cancer occurs with screening by endometrial sampling. The NCI notes that based on solid evidence, endometrial biopsy sampling may result in discomfort, bleeding, infection, and in rare cases uterine perforation.
In addition, risks associated with false-positive test results include anxiety and additional diagnostic testing and surgery. Furthermore, endometrial cancers may be missed on endometrial sampling. The Pipelle endometrial sampling device is the most popular method for sampling the endometrial lining Guido, Various types of brushes have also been used for endometrial sampling. Although the brush appears to be as effective or better than other blind methods of endometrial sampling, these devices have been evaluated in only a few studies with small numbers of subjects Tao, ; Tao, ; Critchley et al, ; Yang et al, ; Del Priore et al, ; Yang and Wan, ; Maksem et al, Twenty-two had cancer or atypia, the others had benign diagnoses.
