Fetal failure

Fetal failure's disease overview

The fetus can receive oxygen to maintain life and grow in the womb thanks to a circulation between the mother and the fetus that is the uterine-vegetable-fetus circulation. That is, oxygen -rich blood transmits the baby through the placenta in charge of providing oxygen to the fetus, if for a certain reason, this circulatory affects the reduction of blood to the lake, or from spikes to the fetus, will Reduce the amount of oxygen to the fetus and cause fetal failure .

Lack of oxygen can occur acute, which is a sudden deficiency of the fetus or slowly lasting for many days called chronic lack of oxygen. Whether the lack of acute or chronic oxygen, the fetus still has the ability to compensate in the early stages, to some extent the fetal body is no longer able to compensate for fetal failure and show in the forest. Sound.

The compensation mechanism in pregnancy: The lack of fetal body oxygen can be identified, thereby adjusting the blood distribution that is to increase blood to important organs such as brain, heart, liver and decrease The amount of blood to less important organs such as intestines, skin, and kidneys. Lack of oxygen or prolonged the fetus is no longer able to respond to brain oxygen, heart deficiency, organized oxygen deficiency leads to anaerobic metabolism, acidosis and can die in the uterus or die after lay.

Fetal failure is divided into 2 groups: acute fetal failure and chronic fetal failure seriously affects the mother and baby can lead to death

  • Acute pregnancy often occurs in the process of labor, maybe death immediately, mild can affect the mental and physical development of the baby in the future. If it is not detected and managed promptly. Acute pregnancy accounts for less than 20% of births.
  • Chronic fetal failure occurs slowly during pregnancy, there is no obvious manifestation, difficult to detect clinically and more dangerous than Can turn into acute fetal failure during labor can die in the womb, seriously affecting the uterus of the mother and the ability to be a mother later

    • If the fetal failure is diagnosed and treated promptly, the rate of the fetus is highly rescued, so mothers need basic insights about fetal failure to be hospitalized. and timely treatment to avoid unfortunate happening.

    Causes of Fetal failure's disease

    Can be divided into the following groups of causes of fetal failure:

    Causes from the mother : The causes of reducing the peripheral blood of the mother all lead to the amount of blood to the uterus

  • Mother's lying position: lying on your back as the uterus presses into the aorta causing a decrease in the mother's blood.
  • Anemia in the mother due to any cause: bleeding, chronic anemia, low blood pressure
  • Mothers suffer from chronic diseases such as diabetes, obesity, heart failure, bacterial infections, virus infections
    • uterine contractions: In each uterine contract, uterine circulation-each other is interrupted for 15-60 seconds, the amount of blood supply will be reduced by about 50%. Therefore, when the uterus occurs, the arteries are pinched, so the amount of blood to the blood lake decreases. The first phase of the fetus can compensate. If the frequency, the intensity of the contractions increase, the prolonged contraction time will increase the time of stopping blood circulation between mother and child, leading to fetal failure

    Causes from pregnancy:

  • Monthly pregnancy
  • Monthly pregnancy: Overcoming pregnancy often has calcified cake, the process of supplying oxygen is interrupted, causing the fetus to fail.

    • Anemia, infection, malformed fetus, developmental retardation, ..

    Causes from the appendage of the fetus:

  • striker, each other young, impaired, banh chemicals are calcified, ...
  • The umbilical cord or knots or umbilical cord abnormalities are the cause of obstructing the amount of oxygen transported to the fetus.
  • Early rupture: When the amniotic fluid is broken, reducing the volume of protective protection around the fetus, during labor transitions the uterus can compress the fetal head or wire. The navel, causing oxygen deficiency.
  • The umbilical cord, umbilical knot, umbilical cord or the abnormalities of the umbilical cord are the causes of pregnancy.

    • Other reasons:

  • Difficult laying such as: Immortal between fetus and pelvis, abnormal fetus or some reason leading to prolonged labor
  • Causes of drugs: anesthetic, pain relief, increased shrinkage. In particular, pay attention to the use of contraction drugs in labor in the wrong dose, incompetent, uncontrolled to disrupt uterine contractions leading to fetal failure.

    • Symptoms of Fetal failure's disease

    Signs of fetal failure:

    Change of amniotic fluid color : Normal amniotic fluid, amniotic fluid turns to another color may be a sign of fetal failure, monitoring the color of amniotic fluid helps detect pregnancy early .

  • amniotic fluid turns dark yellow during pregnancy, the fetus may have suffer from pregnancy, the mother needs to be treated immediately.
  • The amniotic fluid turns blue, the pregnant mother has shown signs of fetal failure. In this case, the mother needs to be closely monitored, and depending on the condition of the fetal heart, the stage of labor, the doctor will be treated appropriately for the mother and the fetus.
  • In amniotic fluid, there is a high risk of acute pregnancy failure during labor. This case also needs to be handled quickly, avoiding the situation of inhalation of feces when the fetus is born.

    • Change of fetal heart rate: fetal heart irregularly damaged due to lack of oxygen, fetal heart beating (> 160 beats/minute) in the early stages Or slow dam (<120 beats/ minute) in the period after warning signs of fetal failure. This sign is monitored through obstetric monitoring, so it should be done at regular antenatal check -ups to detect early pregnancy

    The fetus moves chaotic: Sometimes the pedal is strong and much, but sometimes the step is slow and the movement is less. If the fetus is not moved for a long time, it is likely that the fetus has died. One way that can be detected early is counting pregnancy movement . The mother can monitor the fetal movement by lying still in bed, counting the fetus with 4 movements in 30 minutes proves that the fetus is still healthy. Conversely, if within 4 hours and seeing that the fetus has less than 10 movements, the mother needs to go to the prenatal check immediately to check the condition of the fetus. Mother performed 3 times/ day

    these signs were only suggested, but the early signs of suspicion of pregnancy so when there were the above signs, it was necessary to go to a specialized medical facility for examination. and timely detection.

    People at risk for Fetal failure's disease

  • Mothers suffer from chronic diseases such as heart disease, kidney, hypertension, diabetes, respiratory failure, anemia ...
  • Frequently encountered abnormal manifestations such as the fetus, young amniotic fluid, amniotic fluid, striker vegetables, baked buns, toxic toxicity, prolonged labor ... pregnancy and labor.
  • The umbilical cord wrapped in fetal neck when ultrasound, can lead to acute fetal failure, fetal loss ...
  • Pregnant mother lying in the wrong posture, which can cause the uterus into the aorta, causing blood circulation to the uterus to be reduced, hindering the heart of the heart causing the fetus to fall down pressure. Therefore, during pregnancy should lie on the left to ensure safety for the fetus.

    • Prevention of Fetal failure's disease

  • Periodic health check
  • Treatment of chronic diseases before pregnancy
  • There are abnormal signs to be examined immediately

    • Diagnostic measures for Fetal failure's disease

    pregnancy during pregnancy

  • The height of the uterus is not the same as the gestational age (underdeveloped fetus)
  • Reducing pregnancy movements (from 23 hours onwards pregnancy movement less than 12 times in 2 hours) or changing pregnancy movement
  • Change fetal heart rate (over 160 times/minute or less than 120 times/minute)
  • Testing: Oh: amniotic fluid is blue (need to look multiple times)

    • obstetric monitor, oxytocin transmission or nipples appear dip I, dip II, fetal heart does not meet the test without lashes

    Ultrasound determines amniotic fluid index, other abnormal signs

    Insertia in labor

  • blue amniotic fluid (when rupture of amniotic fluid or amniotic fluid)
  • Listening to fetal heart rate (with wooden tubes) changes over 160 times/minute or less than 120 times/minute
  • Continuous monitoring of fetal heart rate with obstetric monitor, the appearance of late fetal heart rate (DIP II) or transforming fetal heart rate or fetal heart rate rang less than 5 spans
    • ultrasound: Determining the amount of amniotic fluid decreases (decreased amniotic fluid index)

    Fetal failure's disease treatments

    during pregnancy:

  • Monitoring of fetal heart rate (stethoscope) after the nipple in and after the contraction to detect a change of heart rate
  • Incarnity many times detected green amniotic fluid
  • Oxytocin test or nipple monitoring by obstetric monitor if any.
  • Determine the maturity of pregnancy to suspend pregnancy in case of indications
  • ultrasound: Mesopotamia diameter (over 90mm, fetus over 38 weeks), Average abdominal diameter (above 94mm, fetus weighing over 2500g), calcification of vegetable cakes with vegetable level 3, Amniotic fluid index (amniotic fluid) on pregnancy ≥ 42 weeks.
  • amniotic fluid index: ≤ 28mm usually requires cesarean section, 28-40mm must suspend pregnancy (causing labor, if the cesarean section is failed), 40-60mm closely monitoring, over 60mm is normal

    • during labor:

  • Detect pregnancy to get pregnant in time. Monitor the condition, the mother's disease, measure the fetal heart rate 10-15 minutes/time, monitor the uterine contractions suitable to the labor stage, if the intensity, the pace must use the CODS. P>
  • Monitor fetal heart rate continuously with obstetric monitor to detect dip II, transformed dip, fetal heart rate that fluctuates with more than 5 beats. If there is DIP II, the dip changes, the fetal heart fluctuates with little eligibility, then the forceps are indicated, not eligible for Forceps, the cesarean section.

    • Measuring amniotic fluid in cases of pregnancy over the date of birth, the amount of amniotic fluid decreases, there are density feces, so the cesarean section should not be challenged to give birth. P>
