It is also possible to learn general anesthesia. Generally speaking, learning anesthesia requires the background knowledge and experience of related medical majors in order to better understand and apply anesthesia-related knowledge and skills. Therefore, in some countries and regions, the anesthesia refresher program requires the applicant to have a surgical or related professional background. However, not all countries and regions have clear requirements for the professional background of the applicants studying anesthesia. In some cases, general practitioners also have the opportunity to participate in anesthesia training programs and obtain the qualification of anesthesiologists through relevant training.
