The scope of anesthesia mainly includes 4 aspects: 1. Clinical anesthesia Involves all the management of the perioperative period before and after anesthesia. Make good preparations for anesthesia, such as understanding the condition and choosing the most appropriate anesthesia and drugs in combination with surgery. In order to reduce the patient’s preoperative mental tension and ensure that anesthesia and surgery proceed smoothly, preanesthetic drugs such as sedatives, analgesics and anticholinergics can be given appropriately. Fasting before anesthesia is necessary to prevent vomiting, aspiration and other comorbidities during anesthesia and surgery. After the patient is received in the operating room, anesthesia is administered according to the operational requirements. During anesthesia and surgery, the patient should be closely observed for changes and necessary treatment. After anesthesia, the patient will be safely transported back to the hospital room or anesthesia recovery room and continue monitoring and treatment until the patient resumes normal physiological function. Make anesthesia records during and after anesthesia. For special problems, discussion should be organized to summarize the lessons learned. 2.Critical care patients or patients with serious complications during anesthesia surgery, such as serious disorders of circulation, respiration, nerves, liver, kidney, metabolism, etc., can be concentrated in intensive care units with precise and valuable instruments and equipment, and be carefully and well monitored and treated by professionally trained medical and nursing staff, in which the anesthesia profession plays an important role and is involved in shock treatment and respiratory therapy, etc. 3.Emergency resuscitation Sudden cardiac and respiratory arrests can occur during surgical anesthesia, and circulatory and respiratory failure can also occur in emergency rooms and wards for various reasons
(such as disease, trauma, drowning, electrocution, traffic accidents, etc.), the need for immediate cardiac and pulmonary resuscitation, which requires the participation of anesthesia workers to rescue. 4.Pain treatment For a variety of acute and chronic pain (such as post-traumatic pain, low back pain, neuralgia, tumor pain, central pain) treatment.
