When it comes to “anaesthesia“, you are not unfamiliar. From the familiar “Hua Tuo San” developed by Hua Tuo, the “general anesthesia”, “local anesthesia”, and “lumbar hemp” that are used in daily life. Do you understand? Today Onion Class will explain the anesthesia to everyone, and answer some common questions about anesthesia for everyone.

Clinical anesthesia is roughly divided into general anesthesia, local anesthesia and spinal canal anesthesia according to its method of use.

Anesthesia is not a sleep with a needle, the work of the anesthesiologist runs through the perioperative period.

Adults undergoing elective surgery should fast for 8 hours and drink for 4 hours before surgery.

The application effect of painless gastrointestinal endoscopy is better than that of ordinary gastrointestinal endoscopy.

General anesthesia has little effect on intelligence.

First Anesthesia

Anesthesia is a reversible functional inhibition of the central nervous system and/or peripheral nervous system produced by drugs or other methods, causing the patient to temporarily lose sensation in whole or in part, thereby making surgery or diagnostic treatment painless. Clinical anesthesia can be roughly divided into three categories: general anesthesia, local anesthesia and intraspinal anesthesia according to the method of use.

general anesthesia

Anesthesia enters the body through inhalation, veins, etc., temporarily inhibits the central nervous system, and makes consciousness disappear. It is collectively called general anesthesia, referred to as general anesthesia. In simple terms, general anesthesia is to wake up (unconsciousness) + no pain )+ Weakness, because the whole body muscles relax, weak breathing, you need to use a ventilator, and the heart muscle has a special structure and can continue to beat. These three states are mainly caused by three different types of drugs. When the drug is metabolized or excreted from the body, the patient’s consciousness and various reflections gradually recover.

Local anesthesia

Use local anesthetics to block spinal nerves, nerve plexus, or nerve endings, and anesthetize the innervation area without affecting the patient’s consciousness. It is suitable for epidermal surgery, small area surgery, short surgery, etc., such as lipomaectomy, trauma debridement Suture, cosmetic surgery, etc.

Spinal anesthesia

Injecting anesthetic drugs into the subarachnoid space or epidural space of the spinal canal, the spinal nerve root is blocked, and the corresponding area innervated by the nerve root is anesthetized. Broadly speaking, it also belongs to “local anesthesia”, such as painless delivery Commonly used drug analgesia is intraspinal anesthesia (epidural block or combined lumbar and hard block).

Onions answer questions

Would you like to take a shot and get a nap if you are under anesthesia?

In addition to alleviating the patient’s discomfort such as pain during the operation, the anesthesiologist’s job runs through the entire preoperative, intraoperative and postoperative period. Before the operation begins, the anesthesiologist needs to perform a pre-anaesthesia assessment for the patient and perform anesthesia; during the operation, the anesthesiologist monitors and regulates the patient’s breath, heart rate, blood pressure, etc. to ensure the safety of the patient’s life during the operation and complete the operation successfully; Let the patient safely get rid of the anesthesia, perform postoperative analgesia on the patients in need, so that the patient can recover without pain, comfort and safety. Therefore, anesthesia is not as simple as taking a shot and going to sleep.

Why do anesthesiologists ask so many questions before the operation?

The primary responsibility of the anesthesiologist is to ensure the safety of the patient’s life. Most anesthesia drugs have a significant effect on the vital organs and system functions of the body, such as the respiratory and cardiovascular systems. Therefore, safe anesthesia begins before surgery. The pre-anaesthesia evaluation and preparation work can greatly resolve the risk of surgical anesthesia, ensure the smooth operation of the operation, and ensure the patient’s smooth recovery after surgery. Therefore, patients should actively cooperate with the anesthesiologist’s preoperative evaluation for their own health and safety.

Why not eat or drink before surgery?

The purpose of fasting before surgery is to avoid gastric reflux and vomiting during the perioperative period. The aspiration of reflux of gastric contents can cause acute respiratory tract obstruction and secondary pneumonia. Complications such as dyspnea and choking are threatened. life safety. Generally, for adults undergoing elective surgery, fasting for 8 hours, fasting for 4 hours, fasting for children (milk) for 4-8 hours and water for 2-3 hours are required. Everyone must follow the doctor’s advice.

Are painless gastrointestinal mirrors better than ordinary gastrointestinal mirrors?

During the application of common gastrointestinal endoscopy, the patient’s nausea, vomiting, pain and other reactions are more obvious, resulting in low compliance of the patient’s examination, and some patients will request to terminate the operation. In addition, for older patients, the degree of tolerance is lower and the risk is greater.

Painless gastrointestinal endoscopy generally uses intravenous general anesthesia (non-intubation), which can minimize the discomfort of the patient’s diagnosis and treatment and ensure the smooth progress of the diagnosis and treatment process. In addition, after the patient receives anesthesia, the gastrointestinal peristalsis will be further suppressed, which is The diagnosis and treatment of gastrointestinal endoscopy is more advantageous, therefore, the application effect of painless gastrointestinal endoscopy is better than ordinary gastrointestinal endoscopy.

Does general anaesthesia reduce people’s intelligence?

The general anesthesia drugs used in modern times have minimal impact on the human body, and the suppression of the central nervous system is reversible. After the operation, it is excreted by the human body metabolism, and the patient’s consciousness and various reflections gradually recover. Every year, millions of people worldwide use general anesthesia for surgery. Practice has proved that under the correct use of professionals, general anesthesia will have little effect on intelligence.
