The anaesthesia science knows the effects and risks of anaesthesia.

In the medical field, anaesthesia plays an indispensable role, particularly in first aid and pain management. This paper will provide information on the importance and specific application of narcotic drugs in both areas. The application of anaesthesia in first aid First aid trauma: anaesthesia can help doctors to better examine and treat patients with severe trauma. To reduce the pain and discomfort of patients by using appropriate narcotic drugs and to reduce their stress and psychological stress, and to enable medical personnel to perform the necessary operations, such as clean-up, stitching, etc., more smoothly. Cardio-pulmonary resuscitation: In the case of CPR, some narcotic drugs can help patients restore a stable heart rate and increase recovery success. At the same time, anaesthesia can alleviate the pain that patients may feel as they recover. Emergency surgery: Anesthesia is of course essential for patients in need of emergency surgery. It not only allows patients to undergo surgery without suffering, but also creates a stable operating environment for surgeons and increases the success rate. Airway management: It is essential to keep the patient ‘ s airway open, usually during first aid. We anesthesiologists can use professional knowledge and skills to quickly and effectively conduct bronchial intubation or other air route management measures to ensure the flow of patients ‘ respiratory tracts. Application of anaesthesia in pain management Acute pain management: Anaesthesia can provide rapid and effective relief for acute pain, such as pain caused by post-operative or acute trauma. Through the use of local, regional or general anesthesia, the most suitable pain management programme can be selected according to the patient ‘ s specific circumstances. Chronic pain treatment: Anaesthesia can also play an important role for chronic pain patients. For example, certain types of chronic pain can be effectively mitigated through neuro-disturbance techniques and operations. In addition, some narcotic drugs can be used for long-term pain management to help patients improve their quality of life, and attention should be paid to addiction options for some drugs. Cancer pain control: Pain is often a great challenge for cancer patients. Anaesthesia can help to control cancer-related pain in a number of ways, including the use of opioids, neurodeficiency techniques, etc., to make cancer patients more comfortable with the treatment process. Pain at birth: The epidural anaesthesia (the popularly known pain-free) is a widely used method of pain-control, usually during childbirth. It can effectively alleviate the pain of the mother without affecting the process of delivery, so that she can more easily receive new life. The importance of anaesthesia in first aid and in pain management is self-evident. It not only alleviates the suffering of patients and improves the effectiveness of disease treatment, but also creates a better working environment for health workers. As medical technology progresses, the field of anaesthesia is also evolving, and the following are some of the more developed trends: Smart monitoring: Real-time accurate monitoring of patients ‘ anesthesia and vital signs using artificial intelligence techniques. New types of narcotic drugs: development of safer and more effective narcotic drugs, reduction of side effects and addiction. Microcreative technology: Combining micro-surgery with micro-surgery, developing more sophisticated local anaesthesia methods to provide more comfortable treatment for more diseases. In short, anaesthesia plays a crucial role in first aid and pain management. It not only alleviates the suffering of patients and improves the effectiveness of treatment, but also creates a better working environment for health-care workers. As medical technology progresses, we have reason to believe that there will be more innovations and breakthroughs in the field of anaesthesia, which will bring better quality medical care to patients.
