Watch out for supine syndrome in late pregnancy

supine hypotensive syndrome When pregnant women lie on their back in the third trimester of pregnancy, they are prone to dizziness, chest tightness, palpitations, pale complexion, blood pressure drop and other symptoms. If they change to the lateral position, all symptoms will disappear quickly.

During the third trimester of pregnancy, the fetus keeps growing, and the weight of the uterus itself is 20 times higher than that before pregnancy. With the weight of the fetus, placenta and amniotic fluid, the weight of the whole uterus is about 6 kg 。 In supine position, the enlarged and weight-bearing uterus will compress the abdominal aorta and inferior vena cava. The abdominal aorta is the main blood supply vessel in the body of pregnant women. Once pressed, it will lead to insufficient blood supply to heart, brain and other tissues and organs, resulting in the above symptoms.

Pregnant women should take the left lying position when sleeping

There are supine, prone, semi recumbent and side recumbent positions. According to scientific principles, it is most scientific for pregnant women to adopt the sleeping position of lying on the left side.

The sleeping posture during pregnancy is closely related to the fetus. For example, when lying on the right side or supine, the blood supply to the fetus will be reduced The left side lying position can supply more blood to the fetus, and then the baby will be more comfortable in the mother's belly. From the perspective of the health of the fetus and baby, pregnant mothers had better choose the left lying position.

If the pregnant woman has difficulty lying on the left side for a long time, When lying flat, cushion, pillow or quilt can be placed on the right hip to tilt the pelvis to the left , can also play the effect of lying on the left side.
