Amniotic fluid is essential for the survival of the baby in utero. When the mother-to-be lacks it, the consequences can be fatal. What are the risks for the baby? What are the treatments ? The point with Dr Caroline Verhaeghe, obstetrician gynecologist.
The amniotic liquid is the biological fluid in which the fetus evolves throughout pregnancy. Essentially composed of urine and pulmonary secretions, it essentially aims to protect the fetus and promote its development. He swallows it, then eliminates it by urinating. But it can happen that the pregnant woman does not have enough amniotic fluid.
The volume of amniotic fluid varies throughout pregnancy. At the beginning, it is only a few milliliters to reach up to 1000 ml at the 34th week of amenorrhea (SA) before decreasing to 800ml at term. ' The terms oligoamnios and anamnios refer to an insufficient amount of amniotic fluid. When there are not enough, we speak of oligomanias and when there are none left at all, we speak of anamnios “, says Dr. Caroline Verhaeghe.
'When there is not enough amniotic fluid, we speak of oligomanias and when there is none at all, we speak of anamnios'.
If in doubt, the obstetrician can assess the amount of amniotic fluid by measuring the large cistern of amniotic fluid. We speak of moderate oligohydramnios when the height is less than 30mm.
Severe oligohydramnios is defined by a height of less than 20mm.
The highlighting of a oligoamnios or an anamnios must systematically search for a It is premature rupture of membranes . ' This is the most common cause of amniotic fluid deficiency, and the diagnosis is quite easily made with a test or even sometimes with a clinical examination alone. , comments the obstetrician-gynecologist. Other possible causes may be:
The treatment is adapted according to the stage of the pregnancy and the cause at the origin of the oligoamnios or the anamnios. First, rest is recommended. 'In the event of a chromosomal abnormality or malformation detected early, a medical termination of pregnancy can be mentioned. If rupture of membranes occurs at an advanced stage of pregnancy permitting, labor can be induced ', report our interlocutrice.Thanks to Dr Caroline Verhaeghe, obstetrician gynecologistSource journaldesfemmes.fr
