Why does general anesthesia cause death_Why does general anesthesia cause death

General anesthesia is a type of anesthesia during surgery. It mainly uses anesthetics to make the patient feel no pain or sensation during the operation. Many times, general anesthesia is required for surgery for some serious diseases. However, some people die unexpectedly after being given general anesthesia. Is this caused by the animal that received the general anesthesia? Can general anesthesia really kill people? Let’s take a look together below.

1. Due to the patient's own disease and the impact of surgical anesthesia, there are deaths in patients undergoing anesthesia during the perioperative period. It is also possible that the time of death occurred during the peri-anesthesia period due to the original serious heart disease or other diseases. Death during the induction period of general anesthesia is often caused by failure of artificial ventilation, severe cardiovascular suppression by drugs, and mechanical failure. Intraoperative mortality is often related to the patient's underlying disease condition and unavoidable complications. Postoperative mortality is often related to the patient, surgery, and anesthesia, and requires specific analysis of specific cases. With the rapid development of the medical industry today, our surgical anesthesia accidents have been reduced to an extremely low point, providing real protection for surgical patients.

2. 1. The significance of local anesthesia

3. Local anesthesia in a narrow sense refers to the use of local anesthetics (Local anesthetics) to infiltrate and block the surgical site locally, thereby blocking the conduction of pain stimuli to sensory nerves. However, the application of this type of anesthesia is limited. It can only be used for some superficial and small-scale operations, such as some eye surgeries, local tumor resection, etc., but it is powerless for larger operations.

4. General anesthesia

5. General anesthesia is a special state achieved by using a series of drugs. In this state, the human body is sedated, and then loses consciousness and pain perception, and maintains a certain degree of muscle relaxation, which can facilitate almost all operations. It is easy to see that local anesthesia uses a single drug, has limited effects, and has little impact on the whole body. However, once the local anesthetic is absorbed into the blood in large quantities, it may still cause side effects in the central nervous system and circulatory system. The most serious ones may even cause cardiac arrest.

6. Therefore, the amount of local anesthetics used is conditional. For example, the safe dose of lidocaine is 3 mg/kg body weight (after adding adrenaline to reduce blood entry, it can be relaxed to 7 mg/kg body weight).

7. The use of general anesthesia is the combined effect of multiple drugs. The harm of general anesthesia to the body is also limited to a certain extent. If everything is within the acceptable range of the human body, then it will be harmless to the body! We must believe that the human body’s metabolic and repair capabilities are extremely powerful! The harm of general anesthesia to the body is only temporary. After the drug effect wears off and it is metabolized by the human body, it will no longer be harmful.
