Is it dangerous to do a foreign water puncture?

At each stage of pregnancy, the physical examinations that pregnant women need to undergo are different. When the pregnancy is about 15 weeks, some pregnant women will undergo amniocentesis. Amniocentesis can directly check the health of the baby in the mother's belly. The effect of this examination is much better than B-ultrasound. However, many pregnant women wonder whether amniocentesis is dangerous before doing it.

Is amniocentesis risky?

Amniocentesis is performed under the guidance of B-ultrasound. The doctor will choose a location with abundant amniotic fluid and will not harm the fetus for the puncture, so it is generally very safe.

With the continuous improvement of science and technology and clinical technology, the safety factor of amniocentesis has been greatly improved. Taking miscarriage, which is of greatest concern to expectant mothers, as an example, literature from the last century reported that the miscarriage rate was about 0.5% (1/200), while literature in recent years has reported that the miscarriage rate caused by it is only 1/1600. However, as an invasive examination, no one can guarantee that amniocentesis will not cause any impact on the fetus and the expectant mother. In addition, the main complications of amniocentesis include bleeding, infection, amniotic fluid leakage, respiratory distress, premature birth, fetal injury, miscarriage, etc.

Complications of Amniocentesis

1. Blood transmission: There is a certain chance that the blood of the expectant mother and the fetus will come into contact. When contact occurs, if the blood of the expectant mother is Rh-negative and the blood of the fetus is Rh-positive, there will be danger.

2. Infection: If the expectant mother has an infection, bacteria may be brought into the amniotic sac during amniocentesis. The infection can cause high fever, uterine contractions and/or abdominal pain, but this situation is very rare.

3. Water rupture: The incidence rate is 1%, and it will heal on its own within a few days.

4. Intra-amniotic inflammation: The incidence rate is 0.1%. It can cause symptoms such as lower abdominal pain and fever, and is very likely to lead to premature birth.

5. Vaginal bleeding: The incidence rate is 1%-2%, which will improve on its own within a few days.

6. Fetal puncture: This rarely happens under the guidance of ultrasound. Occasionally the fetus will move suddenly, and the doctor can usually avoid it immediately. If it is accidentally punctured, it will not have much impact and will heal on its own.

7. Respiratory distress: A few studies have found that fetuses that have undergone amniocentesis are more likely to have respiratory distress problems after birth, with an incidence rate of 1.1%, while fetuses that have not undergone amniocentesis are 0.5%.

Amniocentesis may bring certain risks to pregnant women and fetuses. Therefore, pregnant women are reminded to choose a large, regular public tertiary gynecological hospital when undergoing amniocentesis, and let experienced doctors perform amniocentesis for you to reduce the risks of amniocentesis and ensure that you can complete the amniocentesis smoothly and safely.
