Disorders of maternal blood flow

In order to achieve optimal care of the child, it is essential that the mother’s blood flow functions in sufficient quantities, especially in her uterus. A known low blood pressure (hypotension) of the mother can lead to a reduced blood flow in the uterus and thus also to an undersupply of the child. It is worth mentioning, however, that first-time mothers usually have a uterus that is not as well supplied with blood as a multi-parent.

The contraction of the uterine muscles under a contraction also leads to a momentary interruption of the blood supply and thus to a temporary lack of oxygen for the child. Normally, however, the contractions are not too long and there are only short interruptions, so that the child is not harmed. Treatment as such a disorder depends on its cause.

Malposition of the placenta

If the placenta is too deep in the uterus, the birth can be blocked by the placenta. In this case a normal birth through the vagina becomes impossible. In most cases, the child lies in the uterus crosswise, at an angle or in the pelvic end position due to the placenta being displaced.Such a false deep-seated placenta is called placenta praevia.

Risk factors that lead to such a displacement through the placenta are a high age of the mother, several previous births, previous caesarean sections (Sectio ceasarea), multiple pregnancies as well as scrapings (curettage) and blood group incompatibilities (erythroblastosis). The mother’s consumption of cigrettes, especially of more than 20 cigarettes per day, also shows significant accumulations of placenta praevia and is considered an important risk factor. Placenta praevia can be noticed by varying degrees of mostly painless bleeding, especially in the last third of pregnancy.

The bleeding is caused by pre-birth reshaping and dilation of the uterus and cervix. This causes the deep-seated placenta to be detached somewhat, resulting in bleeding from the vagina. The exact location of the placenta and its deep-seated position is determined during an ultrasound examination.

Pregnancies in which a placenta praevia is detected are usually delivered with a caesarean section after the 37th week of pregnancy. If the pregnancy is before that, bed rest is ordered and the woman will be admitted to the clinic to avoid any stress. Medications are usually given to prevent the uterus from contracting and thus prevent further bleeding.

Here, the placenta (placenta), which is sitting properly, suddenly detaches itself partially or completely. Causes for such a solution are still unknown, but changes in arterial blood vessels are being discussed, resulting in a separation of the adherent surfaces of the uterine layer, as well as injuries on the abdomen or changes in pressure. Women with an early detached placenta have pain.

These can range from touch pain to back pain to abdominal pain that has been destroyed. Bleeding also occurs in this case. However, these are hidden in a quarter of cases and are therefore not noticed immediately.

Once the detached placenta has been detected with the help of an ultrasound and the doctor has gained an idea of the extent of the detachment, the child must be monitored continuously to ensure an adequate supply of oxygen. Here too, the pregnant woman is admitted to the clinic, where she is repeatedly examined in detail to detect any blood loss in time. Taking into consideration the maternal and fetal condition as well as the child’s maturity, a caesarean section is performed as soon as possible or the pregnancy is still monitored to give the child’s development more time, especially from the lungs.
