Background
The conscious analgesic anesthesia (MAC) refers to a process of performing monitoring, appropriate support and treatment by intravenous injection of one or more intravenous anesthetics for anxiolytic, sedative and analgesic enhancement, according to the condition of a patient, in order to overcome discomfort and psychological fear caused by surgery or other treatment, when local anesthesia or no anesthesia is performed. Is one of the hot spots of the clinical work research of anesthesia in recent years. The conscious analgesia anesthesia can increase the comfort level of a patient, eliminate fear and anxiety feeling of local anesthesia and the like to the patient, and the patient forgets and resists anxiety by a sedation technology so as to go through an operation or treatment period in comfortable and peaceful sleep. And compared with general anesthesia, the dosage is less, the anesthesia quality is improved, the stress response is reduced, the hemodynamics is stable, and the patient is conscious after the operation or treatment is finished. Because the patient is awake after the operation, the labor intensity of nursing is reduced, the complication is less, and the hospitalization time is short.
However, most of the current sedation and analgesia anaesthesia, especially intravenous sedation injection, is performed by experienced anesthesiologists. However, the anesthesia doctors have very insufficient manpower, so that the patient-controlled sedation technology appears, but the existing technology needs to set complicated injection parameters, and the setting of the injection parameters is very dependent on the experience of the anesthesia doctors because the individual difference of the patients is objective. Therefore, the existing self-control sedation technology cannot solve the problem of individual administration and achieve the purpose of reducing the working intensity of anesthetists.
