Oligohydramnios is a condition where the amniotic fluid less than normal, which is less than 500 cc.
Cause of Oligohydramnios
Cause of oligohydramnions can not be fully understood. The majority of pregnant women who are not sure what causes it. Cause of oligohydramnions that has been detected is the fetal congenital defects and leaking pouches / membrane of the amniotic fluid surrounding the fetus in the womb. Approximately 7% of infants of women who experienced oligohydramnions, suffered congenital defects, such as the kidney and urinary tract disorders, because the amount of urine produced by the fetus is reduced.
Other health problems are also associated with oligohydramnios is high blood pressure, diabetes, SLE, and problems with the placenta. Women who've had chronic high blood pressure should consult a health care professional before planning a pregnancy to ensure that their blood pressure remains well supervised and medications that they take are safe during their pregnancy.
Epidemiology of Oligohydramnios
Approximately 8% of pregnant women have too little amniotic fluid. Oligohydramnios can occur anytime during pregnancy, although in general often occurs in the last trimester of pregnancy. Approximately 12% of women whose pregnancies beyond the limits of the approximate time of birth (gestational age 42 weeks) was also oligohydramnios, because the amount of amniotic fluid was reduced by almost half of the normal amount during pregnancy at 42 weeks.
Risk Factors of Oligohydramnios
Women with these conditions have a high incidence of oligohydramnios:
- Congenital anomalies.
- Intrauterine growth restriction (IUGR).
- Premature rupture of membranes (PROM) (24-26 weeks).
- Post-maturity syndrome.
- Uterus looks smaller than gestational age and no ballottement.
- Pregnant women feel pain in the stomach at every movement of the fetus.
- Often ends with parturition prematurus.
- Fetal heart sound was heard starting in the fifth and heard more clearly.
- Labor longer than usual.
- When uterine contraction will be painful.
- When the membranes rupture, amniotic fluid very little, even no one came out.
- Acute pain r / t movements of the baby
- Impaired sleep pattern r / t pain
- Risk of injury: the fetus r / t reduction in amniotic fluid
- Anxiety
- Knowledge deficit r / t do not know information
