Hello..i Am A Nurse Of Many Years, I Recently Have

hello..i am a nurse of many years, I recently have been given a chance to go study with a plastic surgeon in my village who runs a clinic/hospital out of his large house, who says he needs so much medical equiptment/supplies/misc....want to know with the exceptions of narcotics ingested or taken in orally, what are some other ways that fresh wounds or minor surgeries can be done with patients being in little pain, meaning what are some numbing or analgesic agents that can be used locally to debrie wouds or do minor surgies?
