Transcription 1 Fetal size and dating: The application of the recommended charts in clinical practice has not been addressed as dating policies and the identification of growth related problems should form part of locally derived protocols. General guidance Dating measurements are used to confirm the postmenstrual dates if known or to estimate the gestational age GA of the fetus when the menstrual history is unknown or unreliable. Normally the earliest technically satisfactory measurement will be the most accurate for dating purposes. Once the gestational age has been assigned, later measurements should be used to assess fetal size and should not normally be used to reassign gestational age. For dating charts the known variable [crown-rump length CRL or head circumference HC ] is plotted along the horizontal X axis, and the unknown variable gestational age GA on the vertical Y axis. Size charts plot the GA on the X axis and the size variable on the Y axis. The plotting of measurements on a dating chart can cause confusion to the inexperienced operator.

ULTRASOUND EVALUATION OF FETAL BIOMETRY AND NORMAL AND ABNORMAL FETAL GROWTH

Currently there is no satisfactory system of morphological staging of the fetal period of development, and the terminology used to describe this time period reflects this confusion. However, they are widely used colloquially within obstetric practice. Staging of fetal development and growth is based on an estimate of the duration of a pregnancy.

Whereas development of a human from fertilization to full term averages days, or 9. If a fetal ageing system is used, it must be remembered that the age of the fetus may be 2 weeks more than a comparable fetus that has been aged from postovulatory days.

The ranges reported reflect the differences among studies in the patient populations under investigation and differences in the criteria used for the diagnosis of each complication. Several studies subdivide such results into those that apply to women of different race, male versus female fetuses, and primiparous versus multiparous gravidas. Standard fetal growth curves are useful for estimating the range of expected fetal weight at any particular gestational age.

However, in order for the growth curves to be useful, all such tables presuppose that the gestational age of the fetus is established properly. Without adequate gestational dating, the standard fetal growth curves cannot be interpreted successfully. The principle limitations of standard fetal growth curves that are derived from population-based studies are as follows: They apply only to fetuses that are of normal size for gestational age and not to those with significant and potentially pathologic growth abnormalities.

The standard deviation SD associated with the mean birth weight estimate at any particular gestational age is wide, typically exceeding grams. The fetus’s gestational age must be known with a high degree of certainty to use the growth curves with any degree of reliability. In general, these growth curves can expect to apply to large populations of pregnant women who have well-dated pregnancies, but the limits of their predictive accuracy make them less than ideal tools for estimating fetal weight for individual patients.

In addition, the fetal growth curves are the most inaccurate at the extremes of fetal weight deviation ie, women carrying fetuses that are either growth restricted or macrosomic.

To ultrasound or not to ultrasound? That is the question. For most pregnant mamas, ultrasounds are just a given. As a natural mama, we want to avoid as many interventions as possible during pregnancy and birth. Some studies also found that when women had an ultrasound for dating they were less likely to be induced for post-term pregnancy. However, if you have a practitioner like a midwife who is ok with continuing to closely monitor a post-term pregnancy, this may not be an issue for you.

The network uses the national Infomed backbone to provide real-time connection between community-based polyclinics in primary health care and the Provincial Medical Genetics Reference Center. The platform has records for 23, pregnant women and sequential clinical data on genetic risk assessment in early pregnancy, first trimester ultrasound, sickle cell anemia screening, alpha-fetoprotein levels, cytogenetic antenatal diagnosis, second trimester ultrasound, delivery and newborn characteristics, neonatal metabolic screening, and infant clinical assessment.

The system makes health care results immediately available and provides health alerts to enable timely preventive care for pregnant women. It also provides guidelines for processes and practices, and streamlines administrative and monitoring activities through statistical reports. The database generates indicators for assessing fetal growth and applies international standards for antenatal ultrasound quality control.

Multiple gestation with significant growth discrepancy Oligohydramnios Post-term pregnancy greater than 41 weeks gestation Pregnancy-induced hypertension Previous fetal demise unexplained or recurrent risk Fetal Movement Assessment A decrease in the maternal perception of fetal movement often but not invariably precedes fetal death, in some cases by several days. This observation provides the rationale for fetal movement assessment by the mother “kick counts” as a means of antepartum fetal surveillance.

In a review on fetal movement assessment, Froen and colleagues noted that while almost all pregnant women adhere to it, organized screening by fetal movements has seen variable popularity among health professionals. Early results of screening were promising and fetal movement counting is the only antepartum testing method that has shown effect in reducing mortality in a randomized controlled trial comparing testing versus no testing.

Although awareness of fetal movements is associated with improved perinatal outcomes, the quest to define a quantitative “alarm limit” to define decreased fetal movements has so far been unsuccessful, and the use of most such limits developed for fetal movement counting should be discouraged. Non-Stress Test The NST is based on the premise that the heart rate of a fetus that is not acidotic or neurologically depressed will temporarily accelerate with fetal movement.

Noting that accurate dating is a research and public health imperative, researchers from the Committee on Obstetric Practice evaluated methods for improving accurate dating of pregnancy in an effort to promote consistency and accuracy among medical professionals when assigning due dates. The committee noted that the gestational due date should be determined as soon as data from the last menstrual period, the first accurate ultrasound examination, or both are obtained.

The due date should be discussed with the patient and recorded in the medical record.

FDA announces comprehensive regulatory plan to shift trajectory of tobacco-related disease, death The U.

Food and Drug Administration today announced a new comprehensive plan for tobacco and nicotine regulation that will serve as a multi-year roadmap to better protect kids and significantly reduce tobacco-related disease and death. The goal is to ensure that the FDA has the proper scientific and regulatory foundation to efficiently and effectively implement the Family Smoking Prevention and Tobacco Control Act.

The agency will also seek input on critical public health issues such as the role of flavors in tobacco products. Tobacco use remains the leading cause of preventable disease and death in the United States, causing more than , deaths every single year. The agency intends to issue an Advance Notice of Proposed Rulemaking ANPRM to seek input on the potential public health benefits and any possible adverse effects of lowering nicotine in cigarettes.

The conductors 26, 28 of a fetal monitor probe 2 , such as a fetal heartbeat monitor electrode, are marked with calibration means corresponding to predetermined distances from a babyward end 20 of the probe 2. The babyward end 20 of the probe 2 is attached to the baby. During labor, the position and progress of the fetus on the birth canal may be inferred by observing the calibration means relative to the outer end of the birth canal. It has long been recognized that monitoring fetal heart beat is an important procedure during the conduct of labo Various methods and apparatus for performing thi monitoring function have been designed over the years.
