Intrauterine Growth Restriction (IUGR): Etiology and Diagnosis
Complete abortion A sub-category of miscarriage spontaneous abortion in which the non-viable pregnancy tissue has completely passed from the uterus, typically without medications or surgical intervention AAFP. A rarely used procedure whereby an abortion is completed by dilating the cervix and extracting the intact fetus from the uterus. Can also be used in stillbirth management, although its use is rare ACOG.
We also place the table from ACOG CO below in terms of allowed discrepancies between ultrasound and first day of LMP. Remember that.
One in 10 infants in the United States is delivered preterm ie, before the 37th week of pregnancy , contributing to the significant burden on the national healthcare system. Nevertheless, a lack of agreement continues among obstetric professional societies on guidelines for standardization of the approach to the diagnosis and management of patients with symptoms of preterm labor PTL. This disparity in consensus has likely resulted in poor identification of women at an increased risk for preterm birth PTB.
This paper presents an overview of several clinical guidelines and recommendations from a variety of studies regarding the use of fetal fibronectin fFN testing and transvaginal ultrasound TVU cervical length measurement, 2 tools that are used to assess the risk of spontaneous PTB sPTB in women with symptoms of PTL. We identify areas of commonality and discord within these publications. Although inconsistencies exist among the published guidelines, algorithms, and studies on how to diagnose and treat women with symptoms of PTL, each of them supports the use of fFN in conjunction with TVU for assessing the risk of sPTB.
In addition, we review a case study from a regional hospital system with results demonstrating the benefits to patients and process outcomes when PTL assessment protocols are standardized, incorporating both fFN and TVU test results. In the absence of consensus on this topic, healthcare providers, administrators, and payers must navigate conflicting recommendations and identify areas of agreement for this evaluation within their own local settings.

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. The common risk factors include maternal causes hypertension, diabetes, cardiopulmonary disease, anemia, malnutrition, smoking, drug use , fetal causes genetic disease including aneuploidy, congenital malformations, fetal infection, multiple pregnancies , and placental causes placental insufficiency, placental infarction, placental mosaicism.
Intrauterine growth determines the perinatal, postnatal, and adult life development.

Sharing their study results in Clinical Biochemistry the authors are recommending that clinical lab directors and obstetric providers follow their lead—and stop using these tests to predict respiratory distress syndrome RDS in fetuses. In , the groups updated their guidelines, advising against using the FLM test to make delivery decisions for the following scenarios: well-dated and suboptimally dated pregnancies, and nonmedically indicated and medically indicated early pregnancies.

Ultrasound for Pregnancy
According to the committee, the goal of antepartum fetal surveillance is to prevent fetal death.

Gynecology (ACOG) and Society of Maternal Fetal Medicine (SMFM), screening in all patients, regardless of maternal age or baseline risk.
Because the human egg is capable of fertilization for only 12 to 24 hours after ovulation the date of ovulation may be taken as being the date of conception. However, ultrasound determination of the date of ovulation has the same imprecision as does the ultrasound estimate of the gestational age and, therefore, a precise date of conception cannot usually be determined as with in vitro fertilization.
In addition, although a woman is most likely to become pregnant if she has sex on the day of ovulation conception may also occur from live sperm still in her reproductive tract on the day of ovulation if she had sex for up to five days before ovulation [26,27]. The due date may be estimated by adding days 9 months and 7 days to the first day of the last menstrual period LMP.
This is the method used by “pregnancy wheels”. The accuracy of the EDD derived by this method depends on accurate recall by the mother, assumes regular 28 day cycles, and that ovulation and conception occurs on day 14 of the cycle. Use of the LMP to establish the due date may overestimate the duration of the pregnancy, and can be subject to an error of more than 2 weeks .
Breakey, PhD. Over the past four decades, there has been a dramatic increase in the number of women having their babies at age 35 and older. In the U. There has also been an increase in the number of first babies born to women who are 35 or older. These increases have been seen across all ethnic groups in the U. Mathews and Hamilton

Please sign in or sign up for a March of Dimes account to proceed. Pregnancy usually lasts about 40 weeks from the first day of your last menstrual period to your due date. A full-term pregnancy lasts between 39 weeks, 0 days and 40 weeks, 6 days. This is 1 week before your due date to 1 week after your due date. Pregnancy usually lasts about 40 weeks days from the first day of your last menstrual period also called LMP to your due date.
Your due date is the date that your provider thinks you will have your baby. This means your pregnancy lasts between 1 week before your due date and 1 week after your due date. Babies born full term have the best chance of being healthy, compared with babies born earlier or later. In the past, a pregnancy that lasted anywhere between 37 to 42 weeks was called a term pregnancy. Health care providers once thought this 5-week period was a safe time for most babies to be born.
In , ACOG and SMFM updated the definitions for term pregnancies because research shows that every week of pregnancy counts for the health of your baby. Lots of important things happen to your baby in the last few weeks of pregnancy. For example, your baby’s brain and lungs are still developing. These definitions can help more babies be born healthy by helping to prevent births that are being scheduled a little early for non-medical reasons.
WHO recommendation on daily fetal movement counting
Pregnancy in healthy women is associated with normal changes in lipid metabolism that are essential for fetal growth and development. However, with the obesity epidemic, we more frequently are confronted with patients with cardiovascular disease that precedes gestation, as well as unmasked cardiovascular disease during pregnancy. These alterations in lipogenesis have been linked to perinatal morbidity and mortality by recent studies which are ushering in the field of dyslipidemia in pregnancy as a hot area for outcomes research.
Normal pregnancy is associated with predicted changes in lipid metabolism and increases in lipid concentration as gestation progresses.

Do Fetuses Feel Pain? What the Science Says
Aetna considers ultrasounds not medically necessary if done solely to determine the fetal sex or to provide parents with a view and photograph of the fetus. 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.
Ultrasonography in pregnancy should be performed only when there is a valid medical indication. ACOG stated, “The use of either two-dimensional or three-dimensional ultrasonography only to view the fetus, obtain a picture of the fetus, or determine the fetal sex without a medical indication is inappropriate and contrary to responsible medical practice.

Redating a pregnancy may occur when there is a discrepancy between the estimated due date EDD calculated by the last menstrual period LMP and that by ultrasound. Care should be taken when redating a pregnancy, especially in the third trimester, as there may be other reasons for a fetus to be small for gestational age e. According to the ACOG redating is more reliable using the earliest available and reliable ultrasound examination surrogates.
For instance, CRL in the first trimester would be more accurate than a debatable uncertain LMP or 2nd-trimester biometrics. The estimated timelines listed below mandates the redating of pregnancy when these differences happen on obstetric US exams.

Pregnant women should receive a dose of the tetanus toxoid, reduced diphtheria toxoid, and acellular pertussis Tdap vaccine during each pregnancy, preferably during the early part of gestational weeks 27 through A strong recommendation coupled with an offer of Tdap from you, their prenatal care provider, is the best single best predictor of vaccination. This strategy not only helps protect the mother from getting and passing pertussis on to her infant, but also provides passive immunity to the infant.
A recent U. To maximize the passive antibody transfer to the infant, you should administer Tdap during the early part of gestational weeks 27 through The level of pertussis antibodies decreases over time, so you should administer Tdap during every pregnancy in order to transfer the greatest number of protective antibodies to each infant. Postpartum Tdap administration only provides protection to the mother — it does not provide immunity to the infant.
It takes about 2 weeks after Tdap receipt for the mother to have protection against pertussis, thereby putting her at risk for contracting and spreading the disease to her vulnerable newborn during this time.
