Rupture of membranes (ROM) or amniorrhexis is a term used during pregnancy to describe a rupture of the amniotic sac. [1] Normally, it occurs spontaneously at full term either during or at the beginning of labor. Rupture of the membranes is known colloquially as " breaking (one's) water," especially when induced rather than spontaneous, or as ...
Prelabor rupture of membranes (PROM), previously known as premature rupture of membranes, is breakage of the amniotic sac before the onset of labour. [2] Women usually experience a painless gush or a steady leakage of fluid from the vagina. [1] Complications in the baby may include premature birth, cord compression, and infection.
73.0. [edit on Wikidata] Artificial rupture of membranes (AROM), also known as an amniotomy, is performed by a midwife or obstetrician and was once thought to be an effective means to induce or accelerate labor. The membranes can be ruptured using a specialized tool, such as an amnihook or amnicot, or they may be ruptured by the proceduralist's ...
The amniotic sac, also called the bag of waters[1][2] or the membranes, [3] is the sac in which the embryo and later fetus develops in amniotes. It is a thin but tough transparent pair of membranes that hold a developing embryo (and later fetus) until shortly before birth. The inner of these membranes, the amnion, encloses the amniotic cavity ...
Ferning is now most commonly used as a test for prelabor rupture of membranes which refers to the rupture of the amniotic sac during pregnancy. The sodium chloride content of amniotic fluid secreted by the fetal kidneys may be indicative that membrane rupture has occurred, though the pattern of 'ferning' seen in amniotic fluid is distinct from ...
If the amniotic sac has not yet broken during labour the health care provider may break it in a technique called an amniotomy. In an amniotomy a thin plastic hook is used to make a small opening in the sac, causing the water to break. [25] If the sac breaks before labour starts, it's called a prelabour rupture of membranes. Contractions will ...
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.
There are also risks associated with membrane sweeping. The risks include irregular contractions, bleeding, and in 1 out of every 10 women an amniotic sac rupture, which can lead to a formal induction within 24 hours of the rupture if labor hasn't been induced. [4] The use of intrauterine catheters are also indicated.
