Deep dives
The Birth and Evolution of Sepsis
The term sepsis has its origins back in ancient times and has evolved over centuries to represent a systematic immunological response to infections. The modern definition of sepsis emerged in the early 19th century, accompanied by advancements in surgery and the growth of hospitals. Surgeons like Joseph Lister played crucial roles in understanding and treating infections post-surgery.
The Challenging Treatment of Sepsis
Sepsis treatment involves early identification, source control, antibiotics administration, and fluid resuscitation to manage the overwhelming immune response. Mortality rates vary across regions and cases, making sepsis a complex and challenging condition to treat. Research continues to improve outcomes and reduce mortality rates.
The Historical Context of Sepsis
Historically, sepsis has been associated with putrefaction and decomposition. Early medical texts like those by Hippocrates referenced the effects of sepsis. The evolution of surgery, the rise of hospitals, and the introduction of germ theory by pioneers like Joseph Lister have transformed our understanding and management of sepsis.
Germ Theory and Sanitation Revolution
Joseph Lister's contributions to the sanitation revolution and germ theory had a profound impact on the field of surgery and infection control. His use of carbolic acid and acceptance of germ theory transformed surgical practices and paved the way for modern infection control methods.
Conclusion
The history and treatment of sepsis have evolved over time, with advancements in medical knowledge and surgical practices shaping our understanding of this complex condition. From ancient recognition to modern treatment approaches, sepsis remains a significant challenge in healthcare, driving ongoing research and innovations to improve patient outcomes.
Lister's Observations and Experiments
Lister began his medical career by observing the high mortality rates in hospitals due to deadly infections haunting every hospital wing. He noticed that wounds treated meticulously with caustic mercury per nitrate healed well and wondered about the nature of the substances in the wounds. Conducting experiments with living animals, he discovered that inflammation was a normal part of the healing process and sepsis did not always follow.
Lister's Revolutionary Contribution to Medicine
Lister's groundbreaking work on antiseptic practices and germ theory revolutionized surgery and medicine. After experimenting with carbolic acid to prevent infections, he achieved remarkable success in decreasing post-surgical mortality rates. This led to the acceptance of his antiseptic techniques, significantly reducing hospital sepsis cases and mortality rates, marking a monumental advancement in medical practices.
Over the years of the podcast, we have often struggled with questions of why: why pathogens act the way they do, why certain people get sick while others don’t, or why we know little about some diseases. This episode is no exception - sepsis certainly inspires many “whys”. But for perhaps the first time on the pod, we find ourselves grappling not only with “why?” but also with “what?”. What, indeed, is sepsis? Ask a dozen doctors and you may get a dozen different answers. Our first goal for this episode is to sift through the various definitions of sepsis and what we know about its pathology to get a firm handle on this deadly consequence of infection. We then turn our sights to a thrilling period of sepsis history - Joseph Lister and his carbolic acid spray - before attempting to address the status of sepsis around the world today. By the end of the episode, your picture of sepsis may not be crystal clear, but hopefully the edges are a little less blurry.
And helping us to de-blur the edges of sepsis is the wonderful Katy Grainger, leading sepsis and amputee advocate and on the Board of Directors of Sepsis Alliance, who shares with us her harrowing sepsis experience.
