Pocket of water

The term pocket of water is used during the Accouchement or of a Avortement to indicate the part of the ovular Membranes (amnion and Chorion) and Amniotic liquid that it contains directly accessible to the touch Vagin Al

Its more or less flattened or projecting form is an indicator of forecast of the Accouchement. More the pocket of water is punt, approximately more it is difficult to perceive by the inspector plus the forecast of the Accouchement is good: that indicates a good accommodation between the presentation of the Fœtus and the maternal basin.

The respect of the pocket of water during the normal Accouchement is an important component to reduce the néo-native infections. Indeed the rupture of the pocket of water before the appearance of the contractions is called premature Rupture of the membranes. The infectious risk increases in a statistical way as soon as the time rupture of the pocket of water and Accouchement exceeds 12 hours. It is also advised to limit the touches Vagin to after the rupture of the pocket of water always because of the infectious risk.

But the rupture of the pocket of water is one of the treatments of the Dystocie of starting or the cervical dystocie. The rupture of the pocket of water is also used for the Déclenchement of the childbirth by production of Prostaglandine S. the rupture of the pocket of water is a simple gesture carried out with an instrument comprising a point indicated sometimes under the name of amniotome and the rupture is l'*amniotomie*. The immediate risk of the rupture is the Procidence of the cord. This risk is decreased if the presentation is fixed or if a person presses on the uterine bottom to fix the presentation manually. Amnion, contains the amniotic liquid and the Fœtus. The external membrane, the Chorion, contains the Amnion and belonged to the Placenta. It is called also amniotic bubble of air because of his resemblance to a bubble of air. With the light, the amniotic bag seems shining and very smooth, but it is too resistant to be transpierced. -->

Amniotic liquid

The amniotic liquid is the liquid environment saturated with water which surrounds and protects the Fœtus in the amniotic cavity during its growth. It enables him to be driven freely without the wall of the uterus being too tight against its body. It has thus what to play about.

The amniotic cavity grows and starts to fill, especially of water, approximately two weeks according to fecundation. After 10 weeks the liquid contains Protéine S, Carbohydrates, Lipide S and Phospholipide S, Urée and electrolyte S, all things which help the Fœtus in its growth. Most of the Amniotic liquid comes from the urine of the baby. During the second quarters the Fœtus can inhale water, which allows the lungs and the gastro-intestinal Tractus to grow and to develop normally.

The first water is released when the membranes break breaks, what is called commonly “loss of water” or spontaneous rupture of the membranes.

Complications related to the amniotic liquid

An insufficiency of Amniotic liquid (oligoamnios) or an excess (hydramnios) can be a cause or an indicator of problems for the mother and the baby. In both cases however, the majority of the Grossesse S is held in a normal way and the baby is born in good health. The Hydramnios is a risk factor which predisposes with the Procidence of the cord. The Hydramnios is associated with the Atrésie of the esophagus. The amniotic liquid is primarily produced by the mother until the sixteenth week of Grossesse.

The premature rupture before term of membranes (PR) is a case where the amniotic bag lets run out of the liquid before 38 weeks of Grossesse. It can be caused by an infection Bactérie or by a defect in the structure of the amniotic bag, the Utérus, or the collar of the Utérus. It happens that the escape cures spontaneously, but in the majority of the cases of PR, work starts during the 48 hours which follow the rupture of the membrane. When that occurs, it is necessary that the mother receives a treatment to avoid a possible infection of the newborn.

A complication obstétricale, rare but often fatal, is the amniotic embolism, which causes a disseminated intravascular coagulation.

Multiple pregnancies

Sometimes in the case of Grossesse S multiples the Fœtus divide the Amnion and the Chorion. One speaks about monoamniotic Grossesse when each Embryon or Fœtus coming from only one Zygote (Jumeaux monozygotes, called commonly identical twins) is in same Amnion which is itself inside one only Chorion (monochorionic). The diamniotic Grossesse consists of what there is more Amnion inside a Chorion or which each Fœtus has its clean Chorion (dichorionic). In the case of Jumeaux dizygotes (fraternal twins) each one has its clean Amnion and its clean Chorion and they can or not divide same a Placenta.

The fact of dividing same the Amnion (or same the Amnion and same the Placenta) can cause complications in the Grossesse. For example, the umbilical cords of twins monoamniotic can be gotten mixed up, which reduces or the blood food of the Fœtus stops some during their development. The twins monochorionic, who divide same the Placenta, usually share also the blood food of the Placenta. In rather rare cases, blood does not pass in the same proportion of a twin to other by the blood-vessels communicating inside their common Placenta, which causes the Syndrome transfuser-transfused.
