Medical-Surgical
Chemists who create or isolate new drugs in the laboratory are the key players in drug research surgery; The role of the clinician is secondary at best. Clinicians play a larger role in the development of new surgical procedures, though laboratory scientists and others in the background may also play a significant role. Advances in anesthesia have made many new procedures possible, which in turn rely on engineers who have made machines and chemists who have made new drugs. New materials, like the alloys and plastics used to make artificial hip and knee joints, make other operations possible.
