Answer:
Lister added hygienic practices before conducting any operation, making sure that his hands were clean and his clothes fresh.Lister changed the treatment of compound fractures from amputation to limb preservation and opened the way for abdominal and other intracavity surgery.
Step-by-step explanation:
Joseph Lister was the Queen’s surgeon for many years, and introduced the use of rubber drainage tubes after trying it on her. He also showed that sterilized materials could be left inside a patient’s body as needed and used and left sterilized silver wire inside the body to keep broken bones together. And since the silk thread used in internal stitching causes more damage when pulled out after some time, Lister started using sterilized catgut, as this would eventually dissolve.He became the Vice President of the Royal College of Surgeons and President of the Royal Society. He was also President of the British Association for the Advancement of Science.
