Amniotic fluid aspiration is one of the methods for detecting the condition of the fetus during pregnancy. As it is a potentially traumatic examination, doctors will be particularly cautious when conducting an examination. They will strictly follow the operating methods to reduce the impact of amniotic fluid aspiration on women. So, how to operate amniotic fluid aspiration specifically? Let's take a look at the answer.
1. Perform ultrasound. Before doing amniocentesis, it is necessary to perform an ultrasound to determine the specific position of the placenta and the actual condition of the fetus. The purpose of this is to avoid accidental injury to the fetus during the examination process. In addition, the position of the fetus can also be clearly known by touching it with the hand.
2. Select the needle point. After determining the position of the fetus, it is necessary to choose a suitable needle insertion point. After finding it, the skin needs to be disinfected, some disinfectant wipes should be laid, and local anesthesia should be done. After treatment, the needle should be inserted into the female abdomen as carefully as possible, otherwise it may accidentally harm the fetus.
3. Remove amniotic fluid. After the needle enters the uterine cavity, it is necessary to use a syringe to remove the amniotic fluid according to the situation. The amount of amniotic fluid removed is generally controlled at around 2ml. After removal, the amniotic fluid needs to be sent to a biochemical laboratory for experiments or DNA needs to be extracted to see if the fetus has any abnormalities.
