(2026四川广安前锋区高二上期中)

In the mid-19th century,a simple operation could often be a death sentence.Even if a patient survived the surgeon’s knife,they frequently fell victim to deadly infections afterwards.Hospitals were filled with the smell of decay(腐烂),and surgeons saw infection as an unavoidable part of surgery.

Joseph Lister,a British surgeon,was deeply troubled by the high death rates from post-surgical infections.He refused to accept that they were unavoidable.While studying wound inflammation,he learned about the work of Louis Pasteur,who proposed that germs(tiny,invisible organisms) caused decay and disease.This was a revolutionary idea at the time.

Lister made a brilliant connection.He reasoned that if germs in the air were causing wounds to decay,then the solution was to kill these germs before they could enter the wound.He began experimenting with carbolic acid,a chemical used to treat waste water.He

developed a system where he would spray a fine mist of carbolic acid in the air around the operating area,clean surgical tools with it,and soak wound dressings in it.The results were dramatic.The death rate from infection following his surgeries plummeted.

Despite his success,Lister faced significant resistance from the medical community.Many senior surgeons believed that Lister was accusing them of being dirty.They were unwilling to change their old ways.However,Lister persisted,patiently publishing his findings and demonstrating his methods.

Gradually,as other surgeons adopted his antiseptic techniques,the evidence became undeniable.Surgery was transformed.Lister’s principles of killing germs to prevent infection laid the foundation for modern antiseptic surgery.His work,built on Pasteur’s germ theory,saved countless lives and forever changed the course of medicine,turning surgery from a dreaded last resort into a safe,life-saving practice.
