Turning the fetus in knee-chest position at 33 weeks is generally not recommended.
Fetal position check is one of the checkups for pregnant women during pregnancy. Normal fetal position is conducive to normal delivery of the baby. At 28 weeks of pregnancy, if abnormal fetal position is found, such as: breech position, transverse position, etc., if the fetus does not have umbilical cord around the neck, and the amniotic fluid and fetal heart are normal, knee-chest recumbency can be used to help turn the fetus into cephalic position.
However, if it is more than 32 weeks, the fetus is already relatively large, and then use the knee-chest position to turn the fetal position, the chances of success are relatively reduced, on the other hand, may also lead to fetal hypoxia, endangering the baby’s health. In addition, at this time the pregnant woman’s abdomen is already larger, the knee-chest position may cause pressure on the waist, resulting in lumbar muscle and bone damage. Therefore, 33 weeks of pregnancy is generally not recommended to carry out the above operation.
The specific situation needs to be decided by the clinician according to the actual situation of the pregnant woman.
