Ultrasound was done specifically to:
* Determine the age of the fetus. Fetal size, measured by ultrasound, allowing doctors to calculate the date of delivery. More accurate measurement in the first half of pregnancy.
* Rule out or confirm an ectopic pregnancy. Ultrasound can be used to diagnose a tubal pregnancy located in the canal or the abdomen rather than the uterus.
* Identify the possibility of spontaneous abortion. If there is bleeding in early pregnancy, or if the fetal heartbeat or movement appears to have stopped during pregnancy, ultrasound can determine whether the fetus has died and if he will have a spontaneous abortion.
* Confirmation of the double pregnancy.
* To diagnose certain birth defects. Ultrasound can be used to diagnose certain birth defects like spina bifida. If a special ultrasound (level II) to detect abnormalities in fetal development, the doctor may refer you to the patient to a health center specializing in ultrasound evaluation more complex. complexes of different tests can help determine the nature of the problem and what options women account.
* Detects Down’s syndrome. Recent research shows that the ultrasound during the first quarter, combined with maternal blood analysis, blood tests as effective as traditional in the second quarter for the early detection of Down syndrome and other birth defects cromosómicos.3 four ultrasound looks for thickening of the skin behind the fetal neck, called the fold nuchae sometimes appears with Down syndrome. College of obstetricians United States (American College of obstetricians, ACOG) recommends that all pregnant women provides a screening test for Down.4 syndrome
* Evaluation of fetal growth. If the uterus grow slower or faster than expected, ultrasound can help determine whether the problem is caused by the growth of the fetus, with little or amniotic fluid volume excess or other causes. In some cases, the doctor who recommended some ultrasound to monitor fetal growth.
* Determine the cause of bleeding in the second or third trimester of pregnancy. Bleeding is often due to placental problems that may require special care and a cesarean delivery.
* Check the condition of the fetus towards the end of pregnancy. Ultrasound and other tests (such as fetal heart rate monitoring) were used to monitor fetal health during the last trimester of pregnancy (or sometimes before) at high-risk pregnancies. May recommend one or more ultrasound if the mother has chronic health problems such as diabetes or high blood pressure or if the baby’s growth seems to be too slow. In some cases, premature birth may not be suitable for infants.
* To provide guidance for other tests. Doctors use ultrasound as a guide to perform certain diagnostic tests such as amniocentesis and chorionic villus sampling (CVS).
* Determine fetal position when almost for delivery. If the baby is in an abnormal position may require a cesarean delivery.
