Reference table of cervical canal length in late pregnancy

Examinations during pregnancy can effectively monitor the health of the pregnant mother and fetus. If any problems are found, medical intervention can be carried out in time. Moreover, due to pregnancy, the body of a pregnant woman is more prone to changes. Pregnant women need to have a simple grasp of these things. So what is the normal measurement of the size of the cervical canal of a pregnant woman?

Reference table of cervical canal length in late pregnancy

Gynecologists will use ultrasound to determine the length of the cervix and whether the pregnancy is at risk of premature birth. During the 22-24 weeks of pregnancy, if the cervical length exceeds 30mm, it is considered normal. If it is less than 25mm, it indicates a high possibility of premature birth. During the delivery period, the cervix gradually loosens and the cervical opening enlarges from 0.5cm to 10cm, and the baby is delivered. The cervix is ​​located below the uterus, is nearly conical, and is about 2.5cm-3cm long. The cervix of pregnant women undergoing caesarean section may be longer than the standard value.

First of all, there is a reliable reference table for the length of the cervical canal. Pregnant women can refer to the values ​​on this table for judgment based on their own conditions. Under normal circumstances, the length of the cervical canal should be more than 30mm. If the cervix is ​​short, miscarriage is more likely to occur in the late stages of pregnancy.

In fact, after pregnancy, in order to avoid premature birth in the late stage, women should go to the hospital for a cervical length measurement. The accurate measurement value can check the condition of the cervical canal. If the cervical canal is too short, it will have a greater impact on pregnancy. Therefore, pregnant women do not need to be bothered and do not be lazy in doing any of the necessary examinations.

Finally, the condition of the fetus is changing throughout the pregnancy. Every prenatal checkup for pregnant women is to detect the growth and development symptoms of the fetus. Especially in the second half of the pregnancy, fetal heart rate monitoring is very important. It can directly reflect the physical and mental health level of the fetus and must not be ignored.
