This 23 block (1 block = 4 weeks) stage covers broad-based competencies that every trainee must acquire before moving on to more advanced, discipline-specific competencies. This stage is comprised of nine modules: airway and ENT, perioperative medicine, surgery, obstetrics, pediatrics, cardiovascular, pain and regional anesthesia, emergency and critical care, and other. Each module helps the resident to focus on basic assessment and knowledge of anatomy, physiology and pharmacology combined with their application to anesthesia. For example, the airway and ENT module includes one block on ENT surgery and two blocks of airway anesthesia. The obstetrics module includes one block of obstetrics and one block of obstetrical anesthesia. The rotation designated as "other" can be used for research, elective or remediation and allows for flexibility within the program.
