The estimated date of delivery EDD , also known as expected date of confinement [1] , and estimated due date or simply due date , is a term describing the estimated delivery date for a pregnant woman. Confinement is a traditional term referring to the period of pregnancy when an upper-class, noble, or royal woman would withdraw from society in medieval and tudor times be confined to their rooms with midwives, ladies-in-waiting and female family members only to attend them. Except in threatened pregnancies for example, in pre-eclampsia , "lying-in" or bedrest is no longer a part of antenatal care.

Obstetric ultrasonography

Accurate assignment of gestational age at time of fetal death is important for research and clinical practice. An algorithm to estimate gestational age GA at fetal death was developed and evaluated. The SCRN conducted a population-based case-control study of women with stillbirths and live births from to in five geographic catchment areas. Rules were developed to estimate a due date, identify an interval during which death likely occurred, and estimate GA at the time of fetal death. Reliability of using fetal foot length to estimate GA at death was assessed. Only

To compare the accuracy of the reported date of the last menstrual period LMP with that of symphysis-fundal height SFH in the estimation of gestational age GA , using an ultrasound US scan as reference. Gestational age was concurrently assessed by the 3 methods in this prospective, population-based, pregnancy-outcome study conducted in Hyderabad, Pakistan, from June 18, , through August 31, , with women between 20 and 26 weeks of a singleton pregnancy. Knowing gestational age GA accurately is essential for optimal prenatal, delivery, and postnatal care. The expected date of delivery, correct diagnosis of preterm or post-term labor, and differentiation between premature birth and intrauterine growth restriction rest on the estimated GA, as do prenatal counseling and interventions for poor fetal growth as well as the avoidance of unnecessary hospitalization, testing, and interventions such as induction of labor and tocolytic treatment [ 1 , 2 , 3 ]. Furthermore, a close estimation of GA informs research toward improving maternal and neonatal outcomes. And an accurately predicted delivery date PDD is obviously useful to the pregnant woman and her family. As a fetal ultrasound US scan is based on biometric measurements of the fetus, it is considered the gold standard for establishing GA when done before 20 weeks of gestation, when the biologic variations in fetal size and the effects of growth restriction are still small. The accuracy is less if the scan is performed during the third trimester [ 3 , 4 , 5 ]. In many high-resource countries, a first-trimester US scan and a second scan between 18 and 22 weeks are essential parts of obstetric practice because they establish GA and screen for fetal anomalies [ 3 , 6 ].

Pettker, MD; James D.

Obstetric ultrasonography is the use of medical ultrasonography in pregnancy , in which sound waves are used to create real-time visual images of the developing embryo or fetus in its mother's uterus womb. The procedure is a standard part of prenatal care in many countries, as it can provide a variety of information about the health of the mother, the timing and progress of the pregnancy, and the health and development of the embryo or fetus.

In conclusion, especially, large negative discrepancy was associated with increased risks of adverse perinatal outcomes. Initially, the estimated date of delivery EDD is generally calculated based on the first day of the last menstrual period LMP and may later be modified when an ultrasound US scan is performed. According to the International Society of Ultrasound in Obstetrics and Gynecology, clinical decisions should preferably be based on the EDD by US 1 , and based on first trimester ultrasound, if performed. The most frequently used formula for pregnancy dating in Sweden today is based on fetal biparietal measurements during the second trimester US scan, and this formula can be used to predict the day of delivery with a standard deviation SD of 8 days 2 , 3 , 4. A minority of clinics perform first trimester pregnancy dating, with increasing practice during the last decade 2 , 5. Before , the combined information from measurement of the biparietal diameter and femur length were generally used 5.

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. The American College of Obstetricians and Gynecologists, the American Institute of Ultrasound in Medicine, and the Society for Maternal—Fetal Medicine make the following recommendations regarding the method for estimating gestational age and due date:. An accurately assigned EDD early in prenatal care is among the most important results of evaluation and history taking. This information is vital for timing of appropriate obstetric care; scheduling and interpretation of certain antepartum tests; determining the appropriateness of fetal growth; and designing interventions to prevent preterm births, postterm births, and related morbidities.
