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.

My rock, my reminder, my inspiration, my failure Case 1 It was fall and early in my second year of residency. The patient was a year-old male presenting with syncope. Admittedly, he was an alcoholic who was an on-the-wagon, off-the-wagon type. His trip to the ED found him off the wagon for several weeks, deeply depressed, and outwardly self-neglected. His story was not unfamiliar to the ED; lots of alcohol without eating or drinking much else and lots of time on the couch.
Today, he got up to get something from the fridge but found himself at the bottom of a set of stairs. A housemate was kind enough to call EMS when it took more than a few minutes for him to wake up. It was early morning so I had a bit more time than usual to chitchat. He wore a Minnesota Twins jersey. Though I was from the northeast, I told him how I was a big Kirby Puckett fan growing up, which segued into discussion about their current season, game soon-to-be in progress, and the Vikings acquisition of Farve.
Our conversation was natural, comfortable, and enjoyable. All the usual suspects were considered but we thought his low saturations sats were most likely due to his smoking history and low blood pressure due to dehydration. Fluids and albuterol went in, labs came back, and time ticked by.
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.

Ultrasonic Fetal Measurement Standards If we assume a fetus is growing normally, biometric measurements are determined by gestational age, and we can estimate the gestational age and thus the due date. Conditions which alter fetal growth will make the estimates less reliable. Although many embryonic and fetal structures can be measured, only a few measurements are easy and repeatable enough for widespread use. The most common are: The first element to be measurable is the gestation sac of the early pregnancy.
The gestational sac is measured in three dimensions, and the average, the Mean Sac Diameter MSD used for estimating gestational age. The length of the embryo on the longest axis excluding the yolk sac constitutes the crown-rump length. The transverse width of the head at it’s widest. We measure from the the leading edge to leading edge of the bones, because this leading interface is most distinct. Since the head is oval, the error induced by small errors in positioning is small, making for a repeatable, robust measure.
The BPD best used after 12 weeks. The femur length is a repeatable measurement with accuracy similar to the BPD. It is effected by skeletal dysplasias, but since these are rare, it is a reliable measurement which confirms measurements of the head. It is best measured after 14 weeks.
First trimester ultrasound is performed in the first months of a pregnancy. Pregnancy ultrasounds are performed mainly using transabdominal ultrasound. For many women, especially after 8 weeks gestation, sufficient information about the baby may be obtained with transabdominal ultrasound only. However, in the early pregnancy, the developing embryo is very small at 6 weeks gestation, the baby is only mm long and a transvaginal ultrasound may be required to get a better image of the baby.
Transvaginal ultrasound is safe and commonly performed during all stages of pregnancy, including the first trimester. It will not harm you or your baby.
