Replacing abdominal palpation with symphysis-fundal height SFH measurement for the assessment of fetal growth is not recommended to improve perinatal outcomes. A change from what is usually practiced abdominal palpation or SFH measurement in a particular setting is not recommended. SFH measurement is a commonly-practiced method of fetal growth assessment that uses a tape measure to measure the SFH, in order to detect intrauterine growth restriction IUGR.
It also has the potential to detect multiple pregnancy, macrosomia, polyhydramnios and oligohydramnios. For fetuses growing normally, from 24 weeks of gestation, the SFH measurement in centimetres should correspond to the number of weeks of gestation, with an allowance of a 2-cm difference either way Other methods of fetal growth assessment include abdominal palpation of fundal height in relation to anatomical landmarks such as the umbilicus and xiphisternum, abdominal girth measurement, and serial ultrasound measurement of the fetal parameters Accurate low-cost methods for detecting abnormal growth are desirable because ultrasound, the most accurate screening tool, is resource-intensive and not widely available in LMICs.
The ANC recommendations are intended to inform the development of relevant health-care policies and clinical protocols. These recommendations were developed in accordance with the methods described in the WHO handbook for guideline development 2. In summary, the process included: identification of priority questions and outcomes, retrieval of evidence, assessment and synthesis of the evidence, formulation of recommendations, and planning for the implementation, dissemination, impact evaluation and updating of the guideline.
Up-to-date systematic reviews were used to prepare evidence profiles for priority questions. To ensure that each recommendation is correctly understood and applied in practice, the context of all context-specific recommendations is clearly stated within each recommendation, and the contributing experts provided additional remarks where needed.
In accordance with WHO guideline development standards, these recommendations will be reviewed and updated following the identification of new evidence, with major reviews and updates at least every five years.
ACOG Issues New Prenatal Testing Guidelines
Intrauterine growth restriction IUGR is associated with perinatal morbidity and mortality. IUGR is defined as fetus that fails to achieve his growth potential. The identification of IUGR is important.
ACOG Guidelines: Management of Late-Term and Postterm Pregnancies for pregnancies that go beyond the estimated date of delivery.
Join NursingCenter to get uninterrupted access to this Article. Accurate determination of the estimated due date EDD during pregnancy has personal and social significance for the woman and her family, guides obstetric evaluation and intervention, and has research and public health consequences. Ultrasound measurement of the crown-rump length CRL in the first trimester is considered the most accurate estimator of the EDD.
Once the EDD is determined it should be documented in the medical record and discussed with the patient. Although determination of the EDD is a responsibility of the obstetric provider, nurses should be aware of the process of standards-based determination of EDD to give the most accurate and current information to women and their families and to enhance the nurse’s advocacy role surrounding gestational age-based assessments and interventions.

Obstet Gynecol. 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.

The information should not be construed as dictating an exclusive course of treatment or procedure to be followed. 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 EDD should be determined, discussed with the patient, and documented clearly in the medical record.
Subsequent changes to the EDD 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 for estimating the due date, gestational age at delivery represents the best obstetric estimate for the purpose of clinical care and should be recorded on the birth certificate.
For the purposes of research and surveillance, the best obstetric estimate, rather than estimates based on the last menstrual period alone, should be used as the measure for gestational age.
When LMP and Ultrasound Dates Don’t Match: When to Redate?
You can use the calculator below to calculate the doubling time of two beta hCG samples by entering the date of the blood test and the corresponding beta hCG value for that day. If the hCG level is decreasing the the half life will be calculated. To calculate the doubling time of two beta hCG samples: 1. Enter the date the first blood test was drawn and the beta HCG value for the date the sample was drawn 2.
Enter the date the second blood test was drawn and the beta HCG value for the date the sample was drawn. Ultrasonography is the preferred method to verify the presence of a viable intrauterine gestation.

It is prudent of the obstetrician to get a detailed menstrual history including duration, flow, previous menstrual periods, and use of hormonal contraceptive. These factors are used to determine the length of her cycles and ovulation period.

Intrauterine Growth Restriction (IUGR): Etiology and Diagnosis
The best estimated delivery date EDD is determined by the date of the last menstrual period LMP if confirmed by early ultrasound. For deliveries resulting from the use of assisted reproductive technology, the best EDD is based on the known date of fertilization. Accurate pregnancy dating is important to improve outcomes and is a research and public health imperative. The best estimated due date should be documented clearly in the medical records.
If the most recent gestational age is dated before the date of delivery, add the number of days between the most recent gestational age and the date of delivery to the gestational age estimate. The gestational age for the OE is reported in completed weeks.

The information should not be construed as dictating an exclusive course of treatment or procedure to be followed. 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.
Amniocentesis for fetal lung maturity is not recommended as a routine component of decision making when considering delivery in a woman with a suboptimally dated pregnancy. Late-term delivery is indicated at 41 weeks of gestation when gestational age is uncertain, using the best clinical estimate of gestational age. Initiation of antepartum fetal surveillance at 39—40 weeks of gestation may be considered for suboptimally dated pregnancies.
During the antenatal care of a woman with a suboptimally dated pregnancy, it is reasonable to consider an interval ultrasonographic assessment of fetal weight and gestational age 3—4 weeks after the initial ultrasonographic study. The timing of indicated delivery in a woman with a suboptimally dated pregnancy should be based on the best clinical estimate of gestational age.
