Anaesthesia – behind pain-free treatment.

Anaesthesia — behind pain-free treatment, medical anaesthesia is a subject of pain-free treatment and surgical safety. Since the development of medicine, the development of anaesthesia has greatly increased the success of surgery and improved the post-operative experience of patients. Today, anaesthesia is used not only for surgical anesthesia in clinical surgery, but also in a wide range of fields, such as medical diagnosis, pain management and intensive care, as an integral part of modern medicine.The methods of anaesthesia are broadly divided into three broad categories: general anesthesia, local anesthesia and regional anesthesia. The whole-body anaesthesia is a process of complete unconsciousness through intravenous injection or inhalation of anaesthesia. Often used for operations that require long and extensive operations. Local anaesthesia temporarily unconsciouss a particular part of the body through an narcotic drug. It applies to a smaller range of operations or treatments, and patients remain sober under local anesthesia but do not feel pain in the part of the operation. The regional anesthesia is used in larger areas of the body, usually for the lower part of the body, and patients are equally sober but do not feel pain in the area.The central mechanism of anaesthesia is to prevent pain through interference with the transmission of nerve signals. Anaesthesia acts on the brain, spinal cord or outer nerves, temporarily inhibiting the activity of neurons, thus preventing the transmission of pain signals to the brain.Although modern medical technology is very safe, there are risks to any medical intervention. The magnitude of the risk of anaesthesia is usually associated with the patient ‘ s health, age, complexity of the operation and the type of anaesthesia. Potential risks of anaesthesia include allergies, excessive anaesthesia, post-operative vomiting, respiratory inhibition, etc. However, with the development of anaesthesia and modern guardianship techniques, the risk of anaesthesia has been reduced to a low level. Anaesthetists play a crucial role throughout the operation, not only in controlling the use of narcotic drugs, but also in closely monitoring vital signs such as heart rate, breathing, blood pressure, etc. to ensure that the patient completes the operation in a safe, stable and appropriate environment.With advances in medical technology, the field of anaesthesia is moving towards more precision and personalization. The rate of infusion of narcotic drugs can be calculated accurately on the basis of the weight, age and metabolism of the patient, thus achieving more accurate implementation of anaesthesia control. In addition, the application of techniques such as electro-brain monitoring in surgery has enabled anesthetologists to better monitor the depth of the patient ‘ s anesthesia, further improving the safety of the operation and the comfort of the patient.As the patient ‘ s demand for post-operative pain management increases, the medical community is exploring ways to reduce the incidence of post-operative pain and to improve the patient ‘ s post-operative comfort by means of local anaesthesia, nervous retardation and multi-modal pain relief programmes. This not only increases patients ‘ post-operative experience and accelerates post-operative recovery, but also reduces the use of opioid painkillers and reduces the risk of drug dependence.With its unique medical specialization and complexity, the future of anaesthesia will be more precise and personalized through continuous improvements in narcotic drugs, technology and surveillance, helping patients to survive surgery and treatment with minimal pain. Advances in anaesthesia have made it possible to carry out many of the complex operations, which have greatly improved the safety and effectiveness of medical care, thus providing better treatment to patients.
