said that unreliable tests caused a baby to die every day.These alarming claims are based on four studies on the use of ultrasound in early pregnancy.This was a cross-sectional observational study that collected data on women who were scanned in early pregnancy at four London hospitals.Women will be offered an early ultrasound if they experience lower abdominal pain, vaginal bleeding, have a poor obstetric history, or to estimate the gestational age of their baby.Neural tube defects affected around 1 in 800 babies.Gastroschisis, where the intestines develop outside the abdomen, also affected 1 in 2,500 babies. You can discover that a baby has a birth defect before birth, at birth or after the child is born.
The person who carries out the scan, the sonographer, will take measurements of the baby and look carefully at how it’s developing."Bone abnormalities are more often picked up at this scan as the light reflects better off the bones by this time," says Dr Beckett who’s also a spokesperson for the Royal College of Obstetricians and Gynaecologists.Despite what headlines have suggested, early pregnancy ultrasounds are invaluable and highly accurate diagnostic tools, and even using current guidelines, the vast majority of cases would be accurately diagnosed.However, this study has demonstrated there is room to further improve guidelines and the care of women in early pregnancy.Early ultrasounds assess particular symptoms or situations, and differ from the standard antenatal screening ultrasound typically given at 10-14 weeks of pregnancy.To estimate whether a miscarriage has occurred, the health professional performing the ultrasound will look at a number of measurements, including the average length of the ‘gestational sac’ an embryo will grow in and the length of the embryo from the crown to the rump.
