water breaking
Introduction
Introduction to breaking water The membrane rupture before labor is called premature rupture of membranes, and the incidence rate is about 6-12% of the total number of births. Premature rupture of membranes often leads to premature birth, perinatal death, and increased intrauterine and postpartum infection rates. basic knowledge Probability ratio: The incidence of symptoms that must be experienced in a woman's pregnancy must be 100% in a specific population Susceptible population: pregnant women Mode of infection: non-infectious Complications: premature birth
Cause
Cause of water breakage
1. Trauma.
2, the internal cervix is slack.
3. Sexual intercourse during the late pregnancy produces mechanical irritation or causes fetal membrane inflammation.
4, lower genital tract infections, can be caused by bacteria, viruses or toxoplasma.
5, the pressure in the amniotic cavity is increased (such as multiple pregnancy, excessive amniotic fluid); the first exposed part of the fetus and the pelvic entrance are not well connected (such as the head basin is not called, abnormal fetal position, etc.).
6, fetal membrane dysplasia to fragile and so on.
Prevention
Water prevention
1. Insist on regular prenatal examination, check once every month for 4-6 months; check once every half month for 7-9 months; check once a week for 9 months or more; Do the inspection.
2. Do not engage in strenuous activities in the middle and late pregnancy. Life and work should not be too tired, keep a happy mood every day, and walk outside properly.
3. It is not advisable to take a long road or run. Be careful not to fall when walking, especially when going up and down the stairs, do not lift things and bump on the road for a long time.
4. Reduce sexual life during pregnancy, especially in the third trimester of pregnancy, the last month of pregnancy prohibits sex, so as not to stimulate the uterus to cause premature rupture of amniotic fluid.
Complication
Water-breaking complications Complications
Premature rupture of membranes is one of the complications of childbirth. Premature rupture of membranes often leads to premature birth, perinatal death, and increased intrauterine and postpartum infection rates.
Symptom
Symptoms of water breakage Common symptoms Deep gestation of late pregnancy or labor... Pregnancy with abdominal pain... False pregnancy
Pregnant women suddenly feel more fluid out of the vagina, followed by a small amount of intermittent discharge.
Premature rupture of membranes can affect the maternal mental burden of the mother and child, can induce premature birth and increase intrauterine infection and puerperal infection. After delivery for 48 hours, the maternal infection rate was 5% to 20%, the sepsis rate was 1:145, and the maternal mortality rate was approximately 1:5500. Infant inhalation of infected amniotic fluid can cause fetal pneumonia, fetal distress; asymptomatic, congenital neonatal pneumonia can also occur after delivery; increased chance of umbilical cord prolapse. The neonatal mortality rate of early rupture correction was reported to be 1.7%. The closer to the full term of pregnancy, the higher the rate of morbidity after rupture of the membrane. Membrane rupture generally does not affect the progress of labor.
Examine
Broken water check
1, the vaginal secretion PH value determination, can be determined by test paper method, such as PH> 7, more has broken the membrane, because the vaginal PH value is 4.5 ~ 5.5, and amniotic fluid is 7 ~ 7.5.
2, vaginal fluid smear, after dry microscopic examination, look at the fern-like crystals, with 0.5 Meilan staining to see pale blue or uncolored fetal epithelium and mane; stained with 0.1 ~ 0.5% Nile Sulfate , check the orange fetal epithelial cells, can diagnose premature rupture of membranes.
3, transabdominal amniocentesis injection of rouge such as by the vagina outflow, the diagnosis can be determined.
Diagnosis
Broken water diagnosis
Diagnosis can be confirmed based on clinical symptoms and examinations.
When the amniotic fluid breaks prematurely, many times the mother often thinks that she is urinating and wet the underwear. I don't know if the amniotic fluid is broken. However, it is very important to determine the premature rupture of amniotic fluid as soon as possible to prevent the bacteria from spreading along the vagina into the uterus. The fetus avoids complications such as umbilical cord prolapse.
When the mother is not sure whether she is prematurely broken or the urine is out, she can put a specific chemical test paper into the vagina. If the amniotic fluid breaks prematurely, the amniotic fluid flowing in the vagina will turn the orange test paper into dark green. Take the test paper to the hospital and observe it under the microscope. You can see small fat blocks and lanugo in the amniotic fluid. At this time, it can be determined that the amniotic fluid is broken.
