Introduction

At 32 weeks of gestation, a biparietal diameter (BPD) of 8.8 cm and femur length (FL) of 6.0 cm are normal. The biparietal diameter refers to the distance from the inner edge of the fetal skull on the far side to the outer edge of the cranial bone plate on the near side, measured perpendicular to the midline of the brain. The typical normal value for BPD at 32 weeks is approximately 8.17 cm; therefore, a measurement of 8.8 cm is generally considered within the normal range. The biparietal diameter is commonly used to assess fetal developmental stage and estimate the timing of delivery.

At 32 weeks of gestation, a fetal biparietal diameter (BPD) of 8.8 cm and femur length (FL) of 6.0 cm are considered normal. Detailed analysis is as follows:

1. Biparietal Diameter (BPD)

The biparietal diameter refers to the distance from the inner edge of the fetal skull on the far side to the outer edge of the skull bone on the near side, measured perpendicular to the midline of the brain. At 32 weeks of gestation, the average normal BPD value is approximately 8.17 cm; therefore, a measurement of 8.8 cm is generally within the normal range. The BPD is commonly used to assess fetal developmental stage and estimate delivery timing. If the BPD at 32 weeks is greater than or equal to 9.0 cm, it may indicate fetal macrosomia, which could affect the choice of delivery method.

2. Femur Length (FL)

The femur refers to the fetal thigh bone. At 32 weeks of gestation, the average femur length is about 6.43 cm, so a measurement of 6.0 cm is typically considered normal. A significantly lower femur length may suggest fetal malnutrition, potentially leading to intrauterine growth restriction. Therefore, adequate nutritional intake during pregnancy is important.

It is recommended that pregnant women undergo regular prenatal check-ups. Normal fetal growth measurements serve only as reference values and cannot be used alone to diagnose fetal development status; further relevant examinations are required for accurate assessment.

Is it normal to have one loop of umbilical cord around the neck at 32 weeks of pregnancy?

In general, one loop of umbilical cord around the neck at 32 weeks of gestation is considered normal. Umbilical cord entanglement refers to the wrapping of the fetal umbilical cord around the neck either once or multiple times. The umbilical cord is the structure connecting the fetus to the placenta, through which oxygen and nutrients are transferred. Umbilical cord entanglement can be observed during ultrasound examinations in pregnant women. At 32 weeks of gestation, there is relatively more amniotic fluid, and the fetus tends to move frequently.

Can I still have a 4D ultrasound at 32 weeks of pregnancy?

A 4D ultrasound can still be performed at 32 weeks of pregnancy, although it is not the optimal time. Four-dimensional ultrasound is an advanced prenatal imaging technique that combines three-dimensional color Doppler ultrasound with real-time motion display. It allows for three-dimensional images and live dynamic videos of the fetus inside the uterus. Performing a 4D ultrasound at 32 weeks enables observation and assessment of fetal development.

What are the causes of sudden stomach pain at 32 weeks of pregnancy?

Abdominal pain refers to pain in the belly. Sudden abdominal pain at night during the 32rd week of pregnancy may be caused by false labor contractions (Braxton Hicks contractions), especially when symptoms become more noticeable after physical exertion. It could also result from acute gastroenteritis due to consuming contaminated food, in which inflammation irritates the gastrointestinal tract and causes abdominal discomfort. If the abdominal pain is severe and accompanied by vaginal bleeding, and ultrasound shows either presence or absence of cervical shortening, it may indicate threatened preterm labor.

Pregnant at 32 weeks, suddenly having frequent bowel movements

Frequent bowel movements at 32 weeks of pregnancy may be caused by diarrhea during pregnancy, dietary factors, digestive system issues, rebound constipation due to edema, or other underlying diseases. Pregnant women are prone to diarrhea due to hormonal changes and alterations in the digestive system. Possible causes include food poisoning, infections, or medication side effects. Treatment includes maintaining adequate fluid intake.
