Amniotic fluid forms from the 12th day after conception, is made up of the fetus, amniotic membrane and blood of the pregnant woman. Amniotic fluid protects the fetus from the invasion of bacteria from the outside, at the same time regenerates energy, provides nutrients for the fetus, helps the fetus avoid the compression of uterine contractions, collisions. , trauma,... In addition, amniotic fluid also helps maintain a stable temperature of the fetus in the uterus, making the baby's muscles and bones stronger.
Outside the amniotic fluid is the amniotic membrane. Amniotic fluid inflammation is an infection of the amniotic sac membrane (occurs in the outer membrane and the amniotic membrane surrounding the fetus) and usually occurs in the later and late stages of pregnancy. The incidence of chorioamnionitis is quite low, only 2% of all births. Amniotic fluid inflammation occurs when bacteria from under the vagina invade the defenses of the uterus. Common bacteria are group B streptococcus, E.Coli and anaerobic bacteria. In addition, prolonged labor after amniotic fluid rupture, premature birth, lower genital tract infections (vaginal and vulvar infections), etc. also increase the risk of amnionitis.

2. How does amnionitis affect pregnancy health?


Amniotic fluid inflammation, if not detected and treated promptly, will lead to many serious complications for pregnant women and fetuses. Specifically:
Causes premature rupture of membranes: When the membranes rupture, it will stimulate labor to bring the baby out. Failure to go into labor increases the risk of infection of the amniotic fluid, causing fetal infection. At the same time, amniotic fluid will flow out, the fetus will not be protected and nourished. Therefore, inflammation of the membranes increases the risk of preterm birth. Premature babies are more likely to have serious complications or die from infections; Maternal Complications: If amniotic fluid is not treated, the mother can face complications such as sepsis, abdominal or pelvic infection, endometritis, and pelvic inflammatory disease. blood clots in the lungs,... In severe cases, the mother can have re-inflammation of the membranes in the next pregnancy or even lose the ability to be a mother; Complications in the fetus: About 95-97% of babies are infected with group B strep if the mother has amnionitis. If left untreated, a child can develop sepsis, respiratory illness, or meningitis (infection of the brain and spinal cord). In some cases, chorioamnionitis occurs at an early stage, and the infection can cause premature labor or stillbirth.
