Normal reactions after amniocentesis

There are many examinations to be done after pregnancy. Pregnancy examinations can not only check the physical and mental health of the pregnant woman, but also know the physical and mental health of the baby in the belly. Amniocentesis is a common maternal examination. It can be performed after 16 weeks of pregnancy. Some people will have some reactions after amniocentesis. So what are the normal reactions after amniocentesis? Many pregnant women need to have a certain understanding of this matter so that they can deal with the problem in a timely manner. Amniocentesis must be carried out in a regular hospital.

All normal reactions after amniocentesis

1. Mild pain

After all, amniocentesis does cause some pain, and some pregnant women feel very obvious pain, so after the amniocentesis, you will continue to feel some pain. However, this kind of pain is not very obvious, just a slight pain, which is a normal reaction. It may also be that the pregnant woman is too anxious when drawing amniotic fluid.

2. Bleeding from pus

Only a very small number of pregnant women will experience a small amount of vaginal bleeding, or find that the secretion is increasing, this phenomenon will naturally disappear within the next few days. If there is bleeding, you need to see how much bleeding there is. If the bleeding is small, there is no need to be too anxious. Just let yourself rest well and do not do strenuous exercise.

Key points of amniocentesis

Based on the typical clinical symptoms of amniotic fluid embolism, the diagnosis can be basically confirmed and treatment should be started first. Clinical symptoms: Typical clinical experience can be divided into three stages.

Shock: Heart failure and acute respiratory and circulatory failure due to pulmonary hypertension, or anaphylactic shock caused by hypersensitivity reaction. At the beginning, pregnant women will experience precursor symptoms such as anxiety, chills, nausea, vomiting, and shortness of breath. Then there will be choking cough, difficulty breathing, cyanosis, wet hiccups at the bottom of the lungs, increased heart rate, pale face, cold limbs, and low blood pressure.

Bleeding caused by DIC: After the patient passes the first stage, he will develop uncontrollable systemic bleeding, including vaginal bleeding, wound bleeding, systemic skin and mucous membrane bleeding, hematuria, and even bleeding in the digestive system. Pregnant women may die from exudative shock.

Subacute renal failure: The main symptoms of patients in the middle and late stages of amniotic fluid embolism are oliguria or anuria and uremia. The main reason is that renal ischemia caused by circulatory failure and venous thrombosis produced in the early stage of DIC block small blood vessels in the kidney, causing renal ischemia and oxygen deficiency, causing organic damage to renal function.

During treatment, blood is extracted from the inferior vena cava and microscopically examined to see if there is any amniotic fluid component from the pregnant woman as the basis for the diagnosis of amniotic fluid embolism. In addition, the following tests can be done: bedside chest X-ray, bedside electrocardiogram, coagulation factor deficiency test (platelet count, blood fibrinogen measurement, prothrombin time measurement, bleeding time measurement) and coagulation test. If the patient dies, an autopsy should be performed. This can lead to pulmonary edema and bronchial bleeding. Intracardiac blood can be checked for visible substances in the amniotic fluid of pregnant women, and the pulmonary arteries or capillaries are blocked by amniotic fluid components of pregnant women. Visible substances in the amniotic fluid of pregnant women can be found in the uterus or broad cruciate ligament blood vessels. The harm caused by amniotic fluid embolism is quite serious and can be life-threatening in severe cases.
