![]() ![]() You will not be able to urinate until the test is over.This makes the ultrasound picture clearer. A full bladder helps transmit sound waves, and it pushes the intestines out of the way of the uterus. You may be able to leave your clothes on, or you will be given a gown to wear. Make sure that a fetus is alive and moving.įetal ultrasound can be done in a doctor's office, hospital, or clinic.Find major birth defects, such as a neural tube defect or heart problems.Check the position of the fetus, umbilical cord, and placenta during a procedure such as amniocentesis or umbilical cord blood sampling.Look at the size and position of the fetus, placenta, and amniotic fluid. ![]() Check for birth defects that affect the brain or spinal cord.Estimate the risk of a chromosome defect, such as Down syndrome.Estimate the age of the fetus ( gestational age).Find out if you are pregnant with more than one fetus.Different details can be learned at different times during your pregnancy. This screening also includes blood tests that measure the levels of two substances that may be related to birth defects.įetal ultrasound is done to learn about the health of your fetus. The first-trimester screening test uses ultrasound to measure the thickness of the skin at the back of the baby's neck. Ultrasound is one of the screening tests that may be done in the first trimester to look for birth defects, such as Down syndrome. Sometimes the sex of your fetus can be seen by about the 18th week of pregnancy. It can be done as early as the 5th week of pregnancy. It does not use X-rays or other types of radiation that may harm your fetus. ![]() It can find things such as the size and position of the fetus. In a transvaginal ultrasound, a transducer is put into your vagina.įetal ultrasound is the safest way to check for problems and get details about your fetus. In a transabdominal ultrasound, a small hand-held device called a transducer is moved over your belly. They may be saved as part of your baby's record.įetal ultrasound can be done two ways. The pictures are also called a sonogram, an echogram, or a scan. It may be in black and white or in colour. It produces a picture of the baby (fetus), the organ that supports the fetus ( placenta), and the liquid that surrounds the fetus ( amniotic fluid). By analogy with cytomegalovirus, toxoplasmosis, and Zika virus infections, it is likely that monkeypox virus is shed in the amniotic fluid only once the fetal kidneys produce sufficient urine (ie, after 18–21 weeks' gestation).Fetal ultrasound is a test done during pregnancy that uses reflected sound waves. The sensitivity of molecular detection of monkeypox virus in the amniotic fluid is unknown. Monkeypox can have considerable risks to the fetus, so we also suggest testing asymptomatic pregnant women with significant monkeypox virus exposure to identify those who require fetal ultrasound follow-up. Fetal ultrasound monitoring is required in cases of maternal monkeypox virus infection, and subsequent management should be based on the presence of ultrasound anomalies such as fetal hepatomegaly or hydrops. Diagnosis is confirmed by nucleic acid amplification testing with real-time or conventional PCR for monkeypox virus from vesicles or genital lesions additionally, we advise ruling out varicella, herpes simplex, and syphilis, as these might resemble monkeypox in pregnancy. Clinicians must maintain a high index of suspicion for monkeypox virus in any pregnant woman presenting with lymphadenopathy and vesiculopustular rash-including rash localised to the genital or perianal region-even if there are no apparent epidemiological links. Here, we propose a clinical management algorithm for pregnant women with suspected monkeypox virus exposure ( figure).
