Walking into the world of anesthesia.

Anaesthesia, as an integral part of modern medicine, plays a key role in surgery and in many medical procedures. Historically, the origin of anaesthesia dates back to ancient times. The use of plant extracts and special herbs to achieve anaesthesia began in ancient Egypt. But it was not until the middle of the nineteenth century that anaesthesia became a true independent subject. Since then, with advances in science and technology, the progressive development of narcotic technologies and drugs has provided strong support for advances in medicine. The types of anaesthesia are varied and consist mainly of general anesthesia and local anesthesia. The whole-body anesthesia, by injection or inhalation of a whole-sphere, causes a brief, reversible sensory disorder in the patient, leaving the body without pain, which applies to complex surgery and to a person in need of it completely unconscious, but may cause complications such as post-operative nausea and vomiting. Local anaesthesia is used around local nerves to give the patient an anaesthesia in a particular region, so that the patient can remain awake during the operation, with the advantage that pain management is well targeted but limited. In addition to the two above-mentioned, there is anaesthesia of the vertebrae, which is used mainly for lower abdominal and lower limb surgery, to achieve anaesthesia by disrupting neurotransmission by injecting the drug into a specific gap within the vertebrae. There is also a neuro-detoxification anaesthesia, which accurately accommodates a specific neuro-dry or neurological bushes, which applies to operations on upper limbs, shoulders, etc. The importance of anaesthesia can be seen in many ways. First, it provides a pain-free operating environment for patients with surgery, which greatly reduces their pain and fear and enables the operation to proceed smoothly. Secondly, anaesthesia ensures the safety of the patient during surgery, and professional anaesthesia doctors conduct an overall assessment of the patient prior to the operation, develop a personalized anaesthesia programme and closely monitor the vital signs of the patient during the operation, and deal with all emergencies in a timely manner. In addition, anaesthesia has important applications for pain management that can be used to alleviate chronic and acute pain and improve the quality of life of patients. However, there is also some misunderstanding about the anaesthesia. There are concerns about brain damage caused by anaesthesia, especially for children and the families of elderly patients. In fact, modern medical research shows that, under normal circumstances, narcotic drugs and methods have little irreversible effect on the human brain. Of course, some cognitive problems may arise when special groups of people, such as children under three years of age, undergo long-term surgical anesthesia or repeated use of whole-body anesthesia over a short period of time, as well as in old age or patients with severe brain disease, but this is not absolute, and the anesthesiologists are able to use and treat them accurately and on an individual basis. In short, anaesthesia is a complex and important medical discipline. It plays an irreplaceable role in alleviating the suffering of patients and ensuring the safety of operations. As medical technology continues to develop, and as narcotic technologies and drugs continue to improve, it is hoped that in the future, safer and more effective anaesthesia services will be provided to patients and that more people will benefit from modern medical care. We should also properly recognize anaesthesia, eliminate unnecessary fear and misunderstanding and actively cooperate with the treatment programmes of doctors to obtain better medical experience and treatment. In addition to surgical anaesthesia, pain management is also an important branch of anesthesia. For chronic pain patients, anaesthetists can use a combination of neurotic retardation, pain injection, drug treatment, etc., to identify the source of pain with precision, to direct the drug to the nerve end or pathology, to effectively relieve pain symptoms and to improve the quality of life of the patient.
