Patient's question:
1 Can an ultrasound be done after four and a half months now?2 Is it okay to check the impact of medication on the fetus at the county people's hospital?
Doctor's answer:
The first ultrasound examination is best performed between the 18th and 20th weeks of pregnancy. During this period, the fetus's organs have fully developed, and a careful ultrasound examination can reveal any abnormalities in each important organ. It allows for the early detection of fetal malformations, enabling timely termination of pregnancy with minimal impact on the mother's health.Later, if there are no abnormal conditions, the second ultrasound can be conducted around the 30th week for a more comprehensive color Doppler ultrasound to assess the development of the baby's organs and. The third ultrasound should be done between the 37th and 38th weeks to determine the position of the placenta and the amount of amniotic fluid, which helps decide whether to have a vaginal birth or a cesarean section.
If the amniotic fluid decreases during the late stages of pregnancy, multiple ultrasound examinations may be necessary, as the less amniotic fluid there is, the higher the risk of fetal hypoxia and birth asphyxia.
