Normally, the placenta attaches to the inner wall of the uterine cavity and peels off and delivers out of the uterine wall within 30 minutes of delivery of the fetus.
Placental abruption, as the name suggests, is when the placenta is partially or completely stripped from the uterine wall before the fetus is delivered.
The main function of the placenta is to provide nutrients and oxygen for the fetus, so small area of placental abruption can easily lead to fetal growth and development restrictions, and large areas of placental peeling are easy to cause fetal intrauterine hypoxia, fetal distress, premature birth, and even stillbirth, stillbirth and other serious consequences. This is also a major reason why babies of older pregnancy age are "stillborn intrauterine".
On the other hand, placental detachment is manifested as postplacental hematoma or bleeding, and when the amount of bleeding is excessive, it can cause hemorrhagic shock, disseminated intravascular coagulation (DIC), amniotic fluid embolism, multi-organ failure, etc. in pregnant women, endangering the life of pregnant women.
How to prevent placental abruption?
1. Regular obstetric examination
On the one hand, abnormalities can be detected in time; on the other hand, hospitals can give priority monitoring and early intervention to pregnant women with high risk factors, and if a critical situation occurs, they can also identify and treat them with emergency treatment as soon as possible.
2. Active treatment can easily lead to the primary disease of placental abruption
For example, pregnant women with hypertensive diseases in pregnancy and diabetes during pregnancy should control blood pressure and blood sugar during pregnancy, avoid frequent blood pressure is too high or fluctuate too much, and keep blood sugar stable.
3. Pay attention to safety
Avoid falling or causing the abdomen to be impacted and squeezed.
4. Avoid staying in the supine position for a long time in the third trimester
Not only is it prone to placental abruption, but it is also easy to form deep vein thrombosis.
5. Abdominal pain, vaginal bleeding or abnormal fetal movements, timely consultation!
This is very, very, very important!!!
