Use the first day of the last menstrual period to calculate the due date. The quick way to do it in your head is to count backwards 3 months from the first day of the LMP, then add 7 days. The second trimester is from weeks until 28 weeks. The third trimester is from 28 weeks until delivery. The mother has had a previous Cesarean delivery but has now delivered vaginally. A cut made with surgical scissors from the opening of the vagina straight back toward the rectum just before the birth. The cut is made from the vaginal opening at an angle more toward the leg than straight back. It used to be taught that it was better to cut an episiotomy than allow a tear, but in the last 25 years all the research in OB literature has shown that lacerations are usually not as large as episiotomies, heal faster than episiotomies, and are less painful than episiotomies. A first degree laceration 1E is minor and does not involve muscle. A second degree laceration 2E is equivalent to a median episiotomy, and does involve some muscle.

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. One notable exception is Gray’s Anatomy. Gray’s Anatomy describes inflation of the neonatal lungs as the first change after birth and does not describe any changes in the afterload of the heart.

The first trimester is months one, two, and three of your pregnancy. Below are scan pictures taken during the early weeks of pregnancy. Measurements taken at these early scans will help to; confirm a pregnancy, date the pregnancy and to see any problems that may occur in the pregnancy low lying placenta, twins etc. Scans in early pregnancy are usually performed in the first trimester around 12 weeks.
You may have a earlier scan, if you are experiencing pain or bleeding for example or unsure of LMP dates. Transabdominal ultrasound TAU and also the transvaginal ultrasound TVU are valuable diagnostic tools in obstetrics and gynecology. Transabdominal ultrasound will provide a panoramic view of the abdomen and pelvis and is noninvasive, whereas transvaginal ultrasound provides a more limited pelvic view and requires insertion of a probe into the vagina.
Transabdominal ultrasound cannot reliably diagnose pregnancies that are less than 6 weeks gestation. Prompt diagnosis made possible by transvaginal ultrasound can, therefore, result in earlier treatment. It is recommended that all pregnant women have a scan in the first trimester, to establish the date when the baby is due, check the number of babies also the position of the placenta. First trimester ultrasonic scans may show ‘soft’ markers for chromosomal abnormalities, such as the absence of fetal nasal bone or an increased fetal nuchal translucency back of the neck to enable detection of Down syndrome fetuses.
While your sonographer takes measurments they will explain what you are looking at. It may not be easy for you to make out what you are seeing on the screen in the early scans.
Fetal growth assessment – decision support
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’.
Nuchal translucency measurement can be maintained between 6 weeks 6 and more information about your first trimester dating scan done at 10 minute. If you a mother has approximately 12 week scan is an ultrasound scan.
Ultrasound Scans Dublin Some Common Questions If you are wondering why you should have an early pregnancy scan , why not take a look at this video where one of our consultants, Dr. Shane Higgins, explains clearly the reasons for attending an early pregnancy scan — just click on: Especially if this is your first pregnancy, you may also be unsure as to when is the earliest you could have your first scan. Normally this 1st trimester scan is undertaken from 6 to 12 weeks.
These weeks refer to the gestational age of your baby, and what this means is that the date is taken from your last period. However we often recommend leaving this scan until after 7 weeks if possible, because at this stage we can normally get more accurate information at your scan. Also this first pregnancy scan is when we should be able to see how many babies are in your uterus, for those of you who are pregnant with multiples.
Of course you will want to know your estimated due date, and we can also give you this information at the early pregnancy scan. Sometimes baby could be located in the fallopian tubes and this can be determined at this time. This is called an ectopic pregnancy. The video features another of our consultants, Professor Fionnuala Mc Auliffe.
Nuchal translucency (NT) scan – BabyCentre UK
Transvaginal ultrasound is performed using a special transducer which is slightly thicker than a tampon. It is covered with a disposable latex sheath and lubricating gel, then gently placed into the vagina. The probe sits in the vagina throughout the examination which usually takes between minutes. Most patients find the examination much more tolerable when compared to a cervical PAP smear. During the scan the sonographer may need to gently press on the abdomen to move bowel out of the way and bring the ovaries and other pelvic structures into view.
This also enables any point of tenderness in the pelvis to be identified.
Available to women from 16 years of age. This service includes a Non Invasive Prenatal Test (NIPT for short, sometimes called the Harmony™ prenatal blood test from Ariosa Diagnostics Inc or Vision™ from Future Health Biobank) and an ultrasound scan.
The test combines pathology results from a blood test and a nuchal translucency ultrasound scan, both matched to your age. The CFTS correlates these findings with a likelihood risk to determine if you are at high risk of having a baby with a chromosomal abnormality, such as Downs Syndrome. The CFTS does not directly diagnose an abnormality, but predicts the likelihood of this type of abnormality being present. Please make your appointment as soon as you receive the referral from your doctor to ensure you are booked during that period.
We recommend patients to book in between 12 and 13 weeks gestation. The fetal gestation age is calculated from the first day of your last menstrual period LMP or from an earlier ultrasound-dating scan so please have this information available when you phone South Coast Radiology to make a booking. The thickness of the nuchal translucency can be measured during your ultrasound scan. Usually, there is an increase in the nuchal translucency when the baby has a chromosomal abnormality.
What is my CFTS risk? All women regardless of age have a small risk of giving birth to a baby with a chromosomal abnormality. The FTS test assesses whether your risk is less than, equal to, or greater than the average risk for your age.
Getting a nuchal scan All pregnant women will be routinely offered the nuchal translucency scan as part of their antenatal care. The scan needs to be done between 10 weeks and 13 weeks plus six days gestation, so many hospitals will include the test as part of your week scan. It is up to you whether you want to have it.
A NATURAL BIRTH ADVOCATE. He is an active supporter of natural birthing options and is willing to attend a home birth. He is supportive of women choosing to have a birth plan and utilizing methods such as HypnoBirthing and Spinning Babies.
It is usually part of an assessment called combined first trimester screening. Combined first trimester screening Combined first trimester screening assesses the risk for your baby having certain chromosomal abnormalities trisomy 13, 18 and This testing combines the nuchal translucency ultrasound with specific blood tests. Nuchal translucency ultrasound alone can also provide this risk assessment, but it is not as accurate as combined first trimester screening.
Combined first trimester screening is a non-invasive way of assessing your risk, which means it does not involve putting needles into the placenta or amniotic sac, as happens with CVS and amniocentesis. This means that combined first trimester screening simply tells us if your risk is low or high.

Can the scan show the gender of my baby? What is actually done? Scans are usually performed by a doctors, midwives or radiographers who are specially trained in ultrasound, and are known as sonographers. The whole pregnancy will be assessed. The amount of liquor amniotic fluid , the position and appearance of the placenta and a detailed scan of the baby itself.
The baby will be measured, and the anatomy examined in detail.
How nuchal translucency scan results are calculated. Your baby’s chances of having a chromosomal abnormality are determined by the nuchal translucency measurement, your age, your baby’s gestational age and the blood test results.

Will I be given a risk level for any other abnormalities? What is nuchal translucency? Nuchal translucency is a collection of fluid under the skin at the back of your baby’s neck. The amount of fluid is measured during a nuchal translucency NT ultrasound scan: That’s why the NT scan is used to help screen for Down’s syndrome. Why might I have a nuchal scan? All pregnant women are offered an NT scan, to help assess whether or not their babies are likely to have Down’s syndrome. Every woman has a chance of giving birth to a baby with Down’s syndrome.
The chance increases as you get older. A screening test tries to get a clearer estimation of whether your baby may have Down’s syndrome.

A look at what your scans will involve. What is nuchal translucency? Nuchal translucency is a collection of fluid under the skin at the back of your baby’s neck. It can be measured using ultrasound: But many babies with Down syndrome have an increased amount Snijders et al Why might I have an NT scan?
Ultrasound uses sound waves to create an image (picture). The sound waves can not be heard and the power of the sound waves used is very low. In pregnancy an ultrasound scan can be used to look at the developing baby, the uterus and the placenta. An ultrasound is safe for both mother and baby.
