One of the most pleasant examinations during pregnancy is the ultrasonic examination. Some inconvenience is connected only by certain condition, which is the bladder should be full enough and the baby can be seen on the screen. Now days there are vaginal sensors that allow doing the scanning without full bladder.
For the best ultrasound passages bared belly cover with a gel layer and then on its surface slowly move the ultrasonic radiator. The ultrasonic device registers the echo of the waves that reflected from a body of the child. The image on the monitor looks as follows: the negative is the fetal fluid and white color is the child.
Normally the examination runs 2 times during pregnancy: between 16th to 20th week and between 32nd and 36th week. Each time the doctor will measure the size of the fetus, and soon after the first measurements it will be easy to count the birth date. For example it is well known that if the fetus height (from head to buttock) is 8 centimeter – it is 10 weeks fetus. At 20th week it is possible to count fingers on hands and feet, and even neck folds. Over here the doctor can recognize the heart parts of the baby, the liver and kidney structure and the brain.
If the pregnancy is complicated the doctor will assign frequent ultrasonic examinations: for instance the doctor detected uterus supertension, pelvic presentation or any other uncommon fetus and umbilical cord position. These tests will not harm both the fetus and the mother. There is only one restriction: that is you have to keep 2 weeks interval between each ultrasonic examination.
Recently they add a new examination, so called Doppler-test, which is possible to do since 18th week. This test allows defining if the fetus or uterus placenta blood flows are as it supposed to be or not.
In the modern maternity clinics that have computers and appropriate equipment, after 32nd week assign monitoring or current cardiograph. You can hear the baby’s heart beats and this is key information for doctor to figure out how the baby feels, how he grows, feed and if there is enough oxygen for him. This test is very safe one, it is effective tool to control and monitor your baby development and there is no need to have special condition
