The harm of anesthetics to the human body

During surgery, anesthesia needs to be injected. Many people are very afraid of anesthesia, fearing that it will affect their health, especially their intelligence. With the advancement of modern medical technology, this worry is becoming more and more unnecessary, because when injecting anesthesia, there will always be an anesthesiologist to do it. As long as the anesthesia is injected in a regular manner, the harm to the body is generally relatively small.

Are anesthetics harmful to the human body?

Patients undergoing general anesthesia enter the operating room. Once everything is ready, the anesthesiologist will put a mask on the patient, and then the patient will slowly "fall asleep". However, what really makes you fall asleep is the anesthetic injected into your body through the vein while you put on the mask, and the mask only provides oxygen. This process is called "anesthesia induction". Some anesthesia inductions are also given by inhaled anesthetics through a mask, allowing you to slowly fall asleep between breaths. After you fall asleep, the anesthesiologist will perform endotracheal intubation, connect the endotracheal tube to the anesthesia machine, control and manage your breathing, and may also give you inhaled anesthetic drugs through the endotracheal tube as needed.

The effect of local anesthetics is to block the transmission of local pain, while general anesthetics work by blocking the central nervous system. If it is a normal person, it can be said that people who are not in special circumstances, general anesthesia is harmless to the human body. Some complications may occur, which are largely caused by the doctor's irresponsibility and are completely avoidable. There is not much use in in-depth explanation. Let me tell you one thing, general anesthesia will not cause complications such as dementia, mental confusion, etc. on the human body as everyone thinks.

In terms of the effects of anesthetics, after general anesthetics are inhaled from the respiratory tract or injected into the human body, they quickly reach the brain through blood circulation, paralyze the central nervous system, and cause the patient to lose consciousness, resulting in general anesthesia. Local anesthetics refer to anesthetics used in the local area of ​​surgery to block local nerve conduction. This prevents the pain stimulation at the surgical site from being transmitted to the brain, achieving the effect of suppressing pain.

When talking about the harm of anesthetics to the human body, Director Chen said: Any drug has its advantages and disadvantages, and anesthetics are no exception. They are harmful to the human body. For example, general anesthetics can inhibit brain function, affect breathing, cause hypoxia, and even lead to circulatory failure and cardiac arrest. Although local anesthetics act locally, they are highly toxic. Once poisoning occurs, it can also lead to respiratory and cardiac arrest. This is just a side effect of the anesthetic itself.

You need to fast before general anesthesia, and you are not allowed to eat secretly

Generally speaking, there is no need for special attention for local anesthesia and topical anesthesia. The patient is conscious and can control swallowing, and will not choke due to vomiting. However, patients under general anesthesia and sleep anesthesia are in a sleeping state. Especially for general anesthesia, muscle relaxants need to be given. Once there is too much food in the stomach and it is not digested, it will reflux back and flow into the trachea by mistake. At this time, the patient is in a deep sleep state and cannot cough or swallow, which will cause danger. If the respiratory tract is blocked or seriously inflamed, and you lose your breath, your life will be in danger!
