Because ultrasound is subjective, there may be inaccuracies. Another study comparing ultrasound to dye dilution techniques in the third trimester found that amniotic fluid index overestimated the actual amniotic fluid volume by as much as Clearly, technical competence is important in the measurement of amniotic fluid index. Screening for Fetal Growth Restriction 4. Serum Biochemistry First trimester combined screening for aneuploidy has been the focus of extensive research. Models incorporate maternal characteristics and serum biochemical markers with nuchal translucency in order to predict adverse outcomes. A raised maternal serum alpha-fetoprotein AFP is associated with an increased risk of low birth weight in the absence of structural abnormality or aneuploidy [ 67 ]. Low levels of maternal serum pregnancy-associated plasma protein A PAPP-A at the lowest 5th percentile are associated with an increased risk of an SGA infant [ 68 , 69 ]. Thirty-two percent of women with this combination delivered a low birth weight neonate less than 2, g [ 70 ].

Preconception care. Preconception care improves maternal and fetal outcomes in women with pre-existing diabetes. This involves educating women about the importance of optimal glycemic control prior to pregnancy, discontinuing potentially harmful medications and achieving a health body weight.

Clinical Background [ return to contents ] Prenatal screening and diagnosis are routinely offered for detection of neural tube defects NTDs , Down syndrome, and trisomy Since the introduction of cell-free DNA testing, screening for trisomy 13 has also been offered. The intent of such screening and diagnosis is to enable pregnant women to make informed decisions regarding their pregnancies and be better prepared in the event of the birth of an affected infant.
The Disorders Neural Tube Defects NTD Neural tube defects NTDs anencephaly, open spina bifida or meningomyelocele, and encephalocele are a heterogeneous group of congenital malformations resulting from a failure of fusion of the neural tube. Anencephaly is almost always fatal at or within a few hours of birth.
This Clinical Focus provides information relating to prenatal screening and diagnosis of neural tube defects, Down syndrome, trisomy 18, and trisomy It includes information about individuals suitable for testing, available tests, and test selection and interpretation for screening and diagnostic tests.
References Progesterone Support in Pregnancy [Figure , p. Furthermore, most of the assessment of progesterone in pregnancy as it relates to various complications of pregnancy was accomplished from the early s through the early s. In spite of improvements in the accuracy and precision of progesterone assays since that time and a better ability to date pregnancy and establish more accurate gestational ages, very little subsequent work has been accomplished in this area.
However, data on the level of progesterone in normal pregnancy, and as it relates to a variety of pregnancy-related complications and features of previous reproductive history has been generated in a study which was conducted from the years through at the Pope Paul VI Institute. Modern means of progesterone assessment with improved accuracy and precision were used along with more precise means of dating the pregnancies.
In this study, patients through pregnancies and 8, progesterone levels were studied and statistically evaluated. These patients were primarily infertility patients who were receiving progesterone supplementation during the course of their pregnancy. Infertility was either primary or secondary and some of the patients also had a history of previous spontaneous abortion and, in some cases, recurrent spontaneous abortion.
The physician reader of this web site should consult that textbook for all of the details. A summary of the statistically significant changes in progesterone levels by condition or event is presented in Table It has also been thought that the placenta takes over the production of progesterone during the second and third trimesters of pregnancy.

Abortion is the ending of pregnancy due to removing an embryo or fetus before it can survive outside the uterus. An abortion that occurs spontaneously is also known as a deliberate steps are taken to end a pregnancy, it is called an induced abortion, or less frequently an “induced miscarriage”.The word abortion is often used to mean only induced abortions.

Testing for single gene mutations Testing for confined placental mosaicism Nucleic acid-based testing for infection Previous Next: Management of Future Pregnancy If a particular medical problem is identified in the mother, it should be addressed prior to conception. For example, tight control of blood glucose prior to conception can substantially reduce the risk of congenital anomalies in the fetus. Preconceptional counseling is helpful if congenital anomalies or genetic abnormalities are found.
Genetic screening and detailed ultrasound can evaluate future pregnancies. In some cases, such as cord occlusion, the patient can be assured that recurrence is very unlikely.

Abstract Expectant management leads to successful vaginal delivery following intrauterine fetal death in a woman with an incarcerated uterus. Management of intrauterine fetal death in the second or third trimester of pregnancy in women with an incarcerated uterus is challenging.
We report a case of successful vaginal delivery following intrauterine fetal death by expectant management in a woman with an incarcerated uterus. In cases of intrauterine fetal death in women with an incarcerated uterus, vaginal delivery may be possible if the incarceration is successfully reduced.

Compared to the previous publication, the current bulletin provides comprehensive management options for ectopic pregnancy by incorporating new guidance on pregnancy of unknown location and on surgical management of ectopic pregnancy, as well as revised guidance on use of hCG levels for diagnosis. Overall, in this Practice Bulletin, ACOG is advocating use of a comprehensive approach and more conservative guidelines to avoid the potential for misdiagnosis, possible interruption of an intrauterine pregnancy or unnecessary medical treatment that could lead to teratogenicity in surviving pregnancies.
While this Practice Bulletin specifically and clearly emphasizes the importance of discussion of risks versus benefits with patients in determining treatment method, there are also other logistical issues that may arise and affect decisions about treatment. Most ectopic pregnancies are managed in the outpatient setting and with minimal variation in the team involved.
In addition, the issue concerning insured and uninsured patients deserves special consideration. It has been shown that there exists substantial insurance-related variation in treatment. In the same article2, the authors also discuss the disparity in that black and Hispanic women were less likely to receive tube-conserving surgery.
The morbidity associated with late preterm delivery is significant and yet many clinicians would be hesitant to commit to expectant management in a fetus at such a low centile. It is our hope that having greater resolution of the risks faced by SGA pregnancies will aid in patient counseling and clinical decision making.
The period-linked live birth and fetal death files from the National Center for Health Statistics NCHS Centers for Disease Control and Prevention for the year were exported and aggregated to form a single database comprising all fetal deaths and births from Jan. We excluded all multiple gestations and major congenital anomalies. The NCHS data set included month and year of birth, gestational age at delivery, birthweight, delivery method, and plurality.
Gestational age was calculated according to delivery date and last menstrual period LMP.

Having this information in advance of the birth means that healthcare staff as well as parents can better prepare themselves for the delivery of a child with a health problem. For example, Down Syndrome is associated with cardiac defects that may need intervention immediately upon birth. Many expectant parents would like to know the sex of their baby before birth. Methods include amniocentesis with karyotyping , and prenatal ultrasound. In some countries, health care providers are expected to withhold this information from parents, while in other countries they are expected to give this information.
Since screening tests yield a risk score which represents the chance that the baby has the birth defect, the most common threshold for high-risk is 1:
