Beware of the ineffectiveness of anesthetics during caesarean section

The failure of anesthetics during cesarean section is relatively rare in clinical practice, but in recent years, there have indeed been media reports of such cases. If the anesthetic fails to work during a caesarean section, it can be extremely harmful to women. In mild cases, it can cause severe pain, and in severe cases, it can cause coma or even death. These are all anesthesia accidents, which can easily lead to vomiting, suffocation, and arrhythmia, and are relatively serious matters.

What is an anesthesia accident?

Anesthesia accident refers to a series of pathological reactions that occur during and after anesthesia. It is mainly reflected in the following aspects:

1. Respiratory system, mainly manifested in vomiting and suffocation, airway obstruction, insufficient ventilation and lung complications;

2. Circulatory system, mainly manifested in: hypotension, arrhythmia, cardiac arrest.

3. Central nervous system, mainly manifested in: high fever, shock and convulsions, slow awakening, etc. In addition, combustion and explosion of anesthetics may occur.

Since it is an accident, it does not happen often. We often encounter unexpected situations of one kind or another in our lives, and anesthesia is no exception. During the anesthesia process, the doctor will first try every possible means to avoid these accidents. Even if an anesthesia accident occurs, the doctor will have corresponding means to correct these accidents and restore the patient to normal. Only a very small number of patients, due to personal physical conditions and other problems, cannot avoid or correct anesthesia accidents despite the doctors' best efforts and ultimately die or suffer permanent disability.

The difference between cesarean section anesthesia and other surgical anesthesia

For many surgeries, the anesthesia method is not very demanding, as long as the patient does not feel pain. However, the anesthesia requirements for cesarean section are particularly stringent, which is determined by the pregnancy physiology of the expectant mother. We all know that the baby in the belly does not breathe by itself. All the oxygen the fetus needs is inhaled by the mother and then passes through the placenta before it can be used by the baby. Any inappropriate anesthesia method or excessive anesthetic drugs may affect this process and endanger the baby's life.

The requirements for anesthesia for cesarean section are:

1. Perfect analgesia and satisfactory muscle relaxation during surgery;

2. Ensure the safety of the mother;

3. Minimum inhibition on the baby;

4. Use drugs that affect uterine contraction with caution.

Why can anesthesia make mothers feel no pain?

The surgery causes pain, which not only brings great suffering to the expectant mother, but also has adverse effects on the central nervous, circulatory, respiratory, endocrine, digestive and autonomic nervous systems, directly threatening the safety of the mother and baby. Therefore, stopping pain is the key to ensuring the success of the operation!

Why can anesthesia prevent a mother who is undergoing surgery from feeling pain? This is because the pain signals need to be transmitted to the brain by nerve fibers to transmit the information that certain parts of the body are injured before the expectant mother can feel the pain. Therefore, the anesthesiologist only needs to use anesthetics to paralyze the peripheral sensory and transmitting nerve fibers in the area to be operated on, so that it temporarily loses the function of transmitting pain signals. In this way, the expectant mother will not feel pain when undergoing surgery in a certain part. This is the basic principle of anesthesia.
