Three month fetal ultrasound indicators

Ultrasound is an important means of evaluating fetal health. The ultrasound indicators of the fetus at three months of pregnancy are mainly used to confirm the basic development of the fetus, exclude obvious structural abnormalities, and verify whether the gestational age is consistent. Common testing items include fetal biparietal diameter, head hip length, fetal heart rate, and preliminary organ development.

1. Analysis of fetal indicators

1. Fetal biparietal diameter: At three months, the biparietal diameter of the fetus is approximately between 1.6-2.5 centimeters. By measuring the distance between the widest parts of the fetal head on both sides, it is possible to evaluate whether the fetal head is developing normally. Excessive size may indicate developmental abnormalities such as hydrocephalus, while insufficient size may be related to developmental delay.

2 Head Hip Length: It is an important indicator for evaluating the overall development level of the fetus. The normal range for head to hip length at this stage is 4-9 centimeters. If the value is too small, it may be necessary to combine other indicators to determine whether there is a possibility of gestational age error or fetal growth restriction.

3 fetal heart rate: The normal range is 120-160 beats per minute, and fluctuations that are too large or too small may indicate fetal heart problems or intrauterine hypoxia, requiring further examination.

4 Preliminary organ development: such as observing the position of the placenta, the closure of the spine, the basic contour of the limbs, and the structure of the brain, these can preliminarily screen for obvious congenital malformations.

2. Factors affecting abnormal ultrasound indicators

1. Genetic factors: Chromosomal abnormalities may cause abnormal indicators, such as Down syndrome and other genetic diseases.

2 External environment: Prolonged exposure of pregnant women to harmful chemicals, drugs, or radiation may affect fetal development.

3 Maternal factors: malnutrition, diabetes, hypertension or poor uterine environment will affect the normal development of the fetus.

4 disease factors: such as congenital heart disease, neural tube insufficiency, or abnormal bone development in fetuses.

3. Suggestions for dealing with abnormal ultrasound indicators

1. Further diagnosis: If abnormalities are detected by ultrasound, more accurate examination methods such as amniocentesis, non-invasive DNA testing, or MRI can be used for clear diagnosis.

2 Adjusting Pregnancy Status: Pregnant women should have a balanced intake of nutrients, supplement essential substances for fetal development such as folate and protein, regularly monitor their physical condition, and have regular check ups.

3 Medical Intervention: If a certain disease is clearly detected, medical intervention measures can be taken, such as intrauterine surgery or other guided treatment interventions.

Three month fetal ultrasound is an important screening method during pregnancy. If abnormalities are found, both spouses should treat them rationally and follow medical advice for subsequent evaluation and treatment. At the same time, pregnant women need to maintain a healthy lifestyle, conduct follow-up pregnancy monitoring, and provide a stable and healthy development environment for the fetus.
