Chorioamnionitis, also known as amnionitis and intra-amniotic infection (IAI), is inflammation of the fetal membranes (amnion and chorion), usually due to bacterial infection. [1] In 2015, a National Institute of Child Health and Human Development Workshop expert panel recommended use of the term "triple I" to address the heterogeneity of this ...
The fetal membranes are the four extraembryonic membranes, associated with the developing embryo, and fetus in humans and other mammals. They are the amnion , chorion , allantois , and yolk sac . [ 1 ]
A premature rupture of membranes (PROM) is a rupture of the amnion that occurs at full term and prior to the onset of labor. [3] In cases of PROM, options include expectant management without intervention, or interventions such as oxytocin or other methods of labor induction, and both are usually accompanied by close monitoring of maternal and ...
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 finger.
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.
The amnion (pl.: amnions or amnia) is a membrane that closely covers human and various other embryos when they first form. It fills with amniotic fluid , which causes the amnion to expand and become the amniotic sac that provides a protective environment for the developing embryo.
The third membrane is the allantois, and the fourth is the chorion which surrounds the embryo after about a month and eventually fuses with the amnion. [ 6 ] Amniocentesis is a medical procedure where fluid from the sac is sampled during fetal development , between 15 and 20 weeks of pregnancy, to be used in prenatal diagnosis of chromosomal ...
In this procedure, a thin needle is inserted into the abdomen of the pregnant woman. [4] The needle punctures the amnion, which is the membrane that surrounds the developing fetus. [4] The fluid within the amnion is called amniotic fluid, and because this fluid surrounds the developing fetus, it contains fetal cells. [4]
