Extra-amniotic administration is a route of administration to the space between the fetal membranes and endometrium inside the uterus of a pregnant woman. It can be used to administer drugs affecting uterus motility, such as oxytocin and prostaglandins , e.g. in labor induction or medical abortion .
Polyhydramnios is a medical condition describing an excess of amniotic fluid in the amniotic sac.It is seen in about 1% of pregnancies. [1] [2] [3] It is typically diagnosed when the amniotic fluid index (AFI) is greater than 24 cm. [4] [5] There are two clinical varieties of polyhydramnios: chronic polyhydramnios where excess amniotic fluid accumulates gradually, and acute polyhydramnios ...
Amnioinfusion is a method in which isotonic fluid is instilled into the uterine cavity.. It was introduced in the 1960s as a means of terminating pregnancy and inducing labor in intrauterine death, but is currently used as a treatment in order to correct fetal heart rate changes caused by umbilical cord compression, indicated by variable decelerations seen on fetal heart rate monitoring.

The amniotic fluid is the protective liquid contained by the amniotic sac of a gravid amniote. This fluid serves as a cushion for the growing fetus, but also serves to facilitate the exchange of nutrients, water, and biochemical products between mother and fetus. For humans, the amniotic fluid is commonly called water or waters (Latin liquor ...
The fetal membranes separate maternal tissue from fetal tissue at a basic mechanical level. The fetal membrane is composed of a thick cellular chorion covering a thin amnion composed of dense collagen fibrils. The amnion is in contact with the amniotic fluid and ensures structural integrity of the sac due to its mechanical strength.
The increased risks include breathing problems in the baby and amniotic fluid embolism and postpartum bleeding in the mother. [3] Established guidelines recommend that caesarean sections not be used before 39 weeks of pregnancy without a medical reason. [6] The method of delivery does not appear to have an effect on subsequent sexual function. [7]
Excessive amniotic fluid indicates that the fetus’ urine output is larger than expected, indicating a larger baby than normal; some symptoms of excessive amniotic fluid include shortness of breath; swelling of lower extremities & abdominal wall; uterine discomfort or contractions; fetal malposition, such as breech presentation.
