Ultrasound exposures that elevate fetal temperature by 4°C above normal for 5 min or more have the potential to induce severe developmental defects.
American Institute of Ultrasound in Medicine consensus report on potential bioeffects of diagnostic ultrasound. National Council on Radiation Protection and Measurements. Criteria Based on All Known Mechanisms. National Council on Radiation Protection and Measurements; Effective prenatal diagnosis relies on a high standard of imaging. Several national and international bodies have described standards for imaging in the first, second, and third trimester of pregnancy.
However, many experts in the field advocate the use of additional views to improve diagnostic performance. In addition to describing the basic components of an obstetrical ultrasound examination in this chapter, we also present extended views that improve the quality of the examination and the detection of pregnancy-related problems. This chapter deals with normal fetal anatomy; however, frequent references to anomalies are made to underscore the pertinence of a good anatomic evaluation.
Each image used in this chapter was obtained using two-dimensional 2D ultrasound. Three-dimensional 3D ultrasound can be a useful adjunct to 2D ultrasound in select circumstances and will be discussed in Chapter 2. All stated gestational ages are according to last menstrual period dating. When performed, the examination is generally limited to determination of the location and number of gestations present, determination of chorionicity in cases of multiple gestations, assessment for viability, and estimation of gestational age.

Gestational age is a measure of the age of a pregnancy which is taken from the woman’s last menstrual period (LMP), or the corresponding age of the gestation as estimated by a more accurate method if available. Such methods include adding 14 days to a known duration since fertilization (as is possible in in vitro fertilization), or by obstetric ultrasonography.
Doppler Ultrasound The doppler shift principle has been used for a long time in fetal heart rate detectors. Further developments in doppler ultrasound technology in recent years have enabled a great expansion in its application in Obstetrics, particularly in the area of assessing and monitoring the well-being of the fetus, its progression in the face of intrauterine growth restriction, and the diagnosis of cardiac malformations. Doppler ultrasound is presently most widely employed in the detection of fetal cardiac pulsations and pulsations in the various fetal blood vessels.
The “Doptone” fetal pulse detector is a commonly used handheld device to detect fetal heartbeat using the same doppler principle. Blood flow characteristics in the fetal blood vessels can be assessed with Doppler ‘flow velocity waveforms’. Diminished flow, particularly in the diastolic phase of a pulse cycle is associated with compromise in the fetus. Various ratios of the systolic to diastolic flow are used as a measure of this compromise.

International conference on transition and cord clamping at birth April It is increasingly recognised that the circulatory changes involved in transition at birth cannot occur within a few seconds of birth. While the healthy fetal circulation and the healthy neonatal circulation are moderately well understood, the underlying triggers, the precise sequence and speed of the changes in the circulation are not. How can we interefere in something we do not understand?
Nearly all textbooks and journals which include the physiological transition of the neonate at birth describe a marked change in the peripheral vascular resistance and an increase in the afterload of the heart.
The fetal crown rump length (CRL) is the measurement between the top of the head to the area above where the legs begin; it is done by ultrasound usually up to the 14th week of the pregnancy.
Inheritance[ edit ] Inheritance is a key feature in CSS; it relies on the ancestor-descendant relationship to operate. Inheritance is the mechanism by which properties are applied not only to a specified element, but also to its descendants. Descendant elements may inherit CSS property values from any ancestor element enclosing them. In general, descendant elements inherit text-related properties, but box-related properties are not inherited. Properties that can be inherited are color, font, letter-spacing, line-height, list-style, text-align, text-indent, text-transform, visibility, white-space and word-spacing.
Properties that cannot be inherited are background, border, display, float and clear, height, and width, margin, min- and max-height and -width, outline, overflow, padding, position, text-decoration, vertical-align and z-index. Inheritance can be used to avoid declaring certain properties over and over again in a style sheet, allowing for shorter CSS. Inheritance in CSS is not the same as inheritance in class-based programming languages , where it is possible to define class B as “like class A, but with modifications”.
However, it is not possible to define a CSS class B like that, which could then be used to style multiple elements without having to repeat the modifications. Given the following style sheet: The style sheet h1 has the color pink, hence, the em element is likewise pink. Whitespace between properties and selectors is ignored. In addition to formatting CSS for readability, you can use shorthand properties to write out the code faster which also gets processed more quickly when being rendered,  like so: Normal flow Inline items are laid out in the same way as the letters in words in text, one after the other across the available space until there is no more room, then starting a new line below.

TYPES OF ELECTROLYTIC SETUPS The manner in which artifacts are set up for electrolysis is dependent upon the following factors (Hamilton , ).
The first Fender solidbody model, the Esquire , lasted in name only from June to October This model name was replaced by the “Broadcaster”, which lasted in name only from the October to January All Broadcasters have truss rods, where many Esquires often have no truss rod. In Gretsch had trademarked the name “BroadKaster” for a line of drums. After advertising the Broadcaster in music trade papers in February 20, , Gretsch took notice and sent Fender a telegram asking them to change their name.
Therefore Fender was forced to drop the name Broadcaster. Starting around February 22, , Fender cut the word “Broadcaster” off of their headstock decals. These models February to summer are known as “NoCasters”. Starting in the summer of , Fender adopted the name “Telecaster” for this model, and started using new decals after all the old clipped decals were used. Decal attachment was the last assembly step, so NoCasters with a February neck date are seen.

With this setup, a conservator is able to precisely regulate the flow of the current to the artifact and maintain a predetermined electrode potential conducive to metal reduction on the surface of the specimen. This setup is used for artifacts that are especially significant and need to be conserved as carefully as possible. The Type 2 electrolytic setup Figure 10B. When this arrangement is used, it is important to make sure that the distance between the different anodes is greater than the distances between the artifact and its anode in order to prevent any cross-over current.
This point is not graphically depicted in Figure 10B. With this setup, the current flow to each artifact can be carefully controlled, and the correct electrode potential can be maintained.

Trimester Calculator – The three basic methods of calculating trimesters are explained. Pregnancy Tests Schedule and quick guide to some of the routine tests used in pregnancy. Week by week pregnancy information table Many find it easy to work out how the weeks, months and trimesters relate to each other on the table above; this has now been added to the top of all the Fetus Development pages , so you can click a week, a month or trimester to see what your little one will be doing in your ‘bump’ at that stage.
Although it may be confusing at first, health care providers begin counting the pregnancy from day one of the last known menstrual period. Yes, that is about 14 – 16 days before you even conceived. There is often confusion when some try to convert weeks into months and count a month as 4 weeks. February is the only month with just 4 weeks. The average calendar month is A normal pregnancy is 40 weeks, or, a little longer than nine average months.
Several years ago World health organizations made an attempt for a universal lunar months method to measure pregnancy length [i. This has just made the confusion worse, with some health care providers using the 10 lunar months method now, while others do not. Timeline breakdowns for pregnancy Days – days from your LMP Gestational or days from conception to birth Fetal age. Weeks – 40 weeks from the start of your LMP Gestational. Most doctors count pregnancy weeks from LMP Gestational , a few others may count from conception to birth Fetal age ; and the week numbers may vary.

A fetus born prior to the 37th week of gestation is considered to be preterm. A preterm baby is likely to be premature and consequently faces increased risk of morbidity and mortality. An estimated due date is given by Naegele’s rule.
To investigate whether the difference between mean gestational sac diameter and crown-rump length (mGSD − CRL) is associated with first-trimester pregnancy loss or adverse pregnancy outcomes after in vitro fertilization (IVF) and to determine if mGSD − CRL is a better predictor of pregnancy loss than either measurement alone.
Underestimation of gestational age by conventional crown-rump length growth curves. Reprinted with permission of American College of Obstetricians and Gynecologists Variations in the measurement of CRL can be attributed to differences in fetal growth patterns. Such differences are related to factors similar to those that influence birth weight curves, including maternal age and parity, prepregnancy maternal weight, geographic location, and population characteristics.
These include incorporation of the yolk sac or lower limbs in the CRL measurement, excessive curling or extension of the fetus, and tangential section of the trunk. The biparietal diameter BPD is one of the most commonly measured parameters in the fetus. Campbell was the first investigator to link fetal BPD to gestational age 20 ; however, since this original report, numerous publications on this subject have appeared in the literature. The BPD is imaged in the transaxial plane of the fetal head at a level depicting thalami in the midline, equidistant from the temporoparietal bones and usually the cavum septum pellucidum anteriorly Fig.

Gestational age assignment is based on the mean BPD; however, a single BPD encompasses a range of ages in which most fetuses of that size are most likely to fall Table 4. A number of factors may contribute to variation or inaccuracy in the BPD measurement.
