Effects of general anesthesia on the brain

Anesthesia is an important way for doctors to relieve patients' pain during surgery. There are many ways of anesthesia, the more common ones are general anesthesia and local anesthesia. Although the use of anesthetics is helpful to the success of the operation, it will also have a certain impact on the human body. Too much or too little will cause pain to the patient! General anesthesia requires more caution. If used improperly, the damage to the brain cannot be underestimated, so everyone needs to be careful.

Will general anesthesia damage the brain?

General anesthesia is a common type of anesthesia during surgery. Most surgeries abroad use general anesthesia technology. As long as it is used properly and the patient pays attention to rest after the operation, it will not have any adverse effects on the patient, nor will it damage the brain. It is safe and reliable.

The dangers of general anesthesia

Some patients may experience dizziness and vomiting after surgery, but these are only temporary side effects and will disappear once the body metabolizes the anesthetic.

Some other patients who underwent general anesthesia experienced respiratory arrest and cardiac arrest during surgery. This was mainly due to the patients' own medical problems or obesity. It may also be because respiratory circulation was not controlled during general anesthesia, leading to this phenomenon.

Kind tips

All medicines are poisonous. Even though today's medicine is relatively advanced, the side effects and risks of anesthesia still exist, but they are all within controllable range. Finally, the editor reminds everyone to pay more attention to health preservation to reduce the occurrence of diseases and use less medicines.

What should patients pay attention to before receiving anesthesia?

Everyone feels nervous and at a loss when facing the challenge of surgical anesthesia, and is often confused about how to prepare to meet this challenge. In fact, there is no need to worry. The development of anesthesiology has established a complete system of preoperative evaluation, intraoperative management, and postoperative support, which can not only achieve painless surgery and painless postoperative period, but also help patients recover quickly and return to a healthy state.

If it is an elective surgery, before anesthesia, patients should pay attention to the following points:

1) Adjust your mindset, face the situation positively, and learn some knowledge about anesthesia and surgery;

2) Quit bad habits such as smoking and drinking, and do functional exercises to improve the body's self-recovery ability;

3) Follow the doctor's advice and strictly follow the preoperative preparations, such as abstaining from food;

4) Communicate boldly and communicate with the surgeon and anesthesiologist if you have any questions or concerns.

At present, many anesthesia disciplines have opened anesthesia clinics, which makes it easier for patients to communicate with anesthesiologists and allows anesthesiologists to better assess the patient's overall condition before surgery, which is very helpful for improving preoperative preparations.

Why is it necessary to abstain from food and drink before anesthesia for surgery?

If there is food in the stomach, vomiting or reflux may occur during anesthesia, and the patient loses consciousness after anesthesia. The pharyngeal reflex that normally protects us disappears, and the glottis at the entrance of the trachea cannot close, which will cause the stomach contents to be accidentally inhaled into the trachea, causing suffocation or aspiration pneumonia. The consequences are fatal! Therefore, in order to ensure the safety of the patient, it is generally required to abstain from food for a period of time before surgical anesthesia.

Is it the job of an anesthesiologist to just give an injection and be done with it?

Of course not. This is a misunderstanding caused by the public's lack of understanding of the nature and connotation of anesthesiologists' work. In fact, under anesthesia, all the patient's physiological functions have changed. During general anesthesia, the patient's breathing will completely stop under the effect of the drug, and the brain will enter a state of rest and unconsciousness. Various physiological functions of the whole body, including the body's self-protection function, will be inhibited, entering an extremely fragile state.

In this situation, the anesthesiologist must pay close attention to multiple aspects such as blood pressure, heart rate, respiration, consciousness, and internal environment, and adjust the drugs and techniques at any time according to the situation, so that the patient is in a safe and stable state during the operation and wakes up safely and smoothly after the operation. This kind of regulation is extremely delicate and individualized, and there can be no negligence for even a minute or a second, otherwise it will lead to extremely serious consequences.
