Fetal abdominal circumference mainly refers to the development of fetal abdomen. By detecting the size of fetal abdominal circumference, we can judge whether the fetus is developing normally. At the 22nd week of pregnancy, the fetal abdominal circumference is about16.70 2.23 cm. If the abdominal circumference exceeds16.70 2.23 cm, it may be fetal obesity, visceral diseases, or pleural effusion. If it is less than 16.70 2.23 cm, it may be that the placental function of pregnant women is not good, and the fetus cannot absorb nutrients, resulting in small size.
More development indicators at 22 weeks of pregnancy: How normal is the fetus at 22 weeks of pregnancy?
The fetus at 22 weeks of pregnancy is about 27 cm long and weighs about 450 grams.
In the 22nd week of pregnancy, the eyebrows and eyelids of the fetus are clearly visible, the fingers also grow small nails, the fetal hair on the head and body also appears, the eyes have developed, the lips are becoming clearer and clearer, the gums have small teeth, and the pancreas is also developing steadily. If it is a male treasure, his testicles begin to enter the scrotum.
How much is the fetal heart rate in 22 weeks of pregnancy normal?
Fetal heart rate can be used to understand the reaction of fetal heart during fetal movement and contraction, so as to infer whether the fetus is hypoxic. At the 22nd week of pregnancy, the normal fetal heart rate is within the range of 1 10~ 160 beats/min. If the fetal heart rate is above 160 beats/min or continuously below 100 beats/min, it indicates intrauterine hypoxia. However, if the pregnant woman has a fever, hyperthyroidism, taking certain drugs, or the fetus has
How much is amniotic fluid index normal in 22 weeks of pregnancy
Amniotic fluid index is an important index for the healthy development of fetus in uterus. The depth of amniotic fluid is an important index to judge whether a child is developing normally. At the 22nd week of pregnancy, the amniotic fluid index is in the range of15.1-15.2 cm, the amniotic fluid depth is about 3-8cm, and the normal amniotic fluid volume is about 200-500ml. Too high amniotic fluid index can easily lead to pregnancy-induced hypertension, premature delivery, placental abruption, postpartum hemorrhage, abnormal fetal position, umbilical cord prolapse and fetal distress. Low amniotic fluid index may be caused by fetal growth retardation or premature development, fetal malformation or urinary system abnormality, placental insufficiency and so on.
Standard of uterine height at 22 weeks of pregnancy
The height of pregnant women's uterus is short for the height of pregnant women's uterus. By measuring the height of uterus, we can indirectly know the growth and development of fetus. The uterine height of pregnant women at 22 weeks of pregnancy is about 18.0-22.5cm. If the uterine height is high at 22 weeks of pregnancy, there are many reasons, such as polyhydramnios, hysteromyoma, macrosomia, or pregnancy with twins or multiple births. If the uterus height is too small at 22 weeks of pregnancy, there are many reasons, such as short stature of pregnant women, small fetal size, or oligohydramnios.
