HISTORY OF SEPSIS
HIPPOCRATES (460-370 BC)
Greek word sipsi = make rotten
IBN SINA (979-1037 BC) - the coincidence of blood putrefaction (septicaemia) and fever
HERRMAN BOERHAVE (1668-1738), a doctor in Leyden, thought that toxic substances in the air were the cause for sepsis.

“It is not by chance that a single obstetrician has 16 fatal cases in a single month - I can only dispel the sadness which falls upon me by gazing into that happy future when the infection will be banished”
1840’s:Lying-in Hospital Vienna
Divided into two clinics- alternating admissions every 24 hours:
1. Doctors and medical students-did autopsies between deliveries
2. Second Clinic: Midwives-came in off the street to deliver-wore gloves outside

Semmelweis’ Hand Hygiene Intervention
Hand antisepsis reduces the frequency of postpartum sepsis
(Hosp Epidemiol Infect Control, 2nd Edition, 1999)
First clinic
2nd clinic
The Intervention:Hand scrub with chlorinated lime solution: removed the putrefying smell from the hands of students and doctors
Hand hygiene basin Vienna, 1847
What was Semmelweiss’s reward in 1848 for this major contribution? - Fired by the hospital board for enforcing handwashing requirement for doctors
LOUIS PASTEUR (1822-1895)
Bacteria / microbes caused
putrefactionKilled by heating – sterilisation
JOSEPH LISTER (1827-1912)
Post amputation mortality – 50%Skin & instrument disinfection
with carbolic acid – antiseptic method
HUGO SCHOTTMULLER (1867-1936)
Modern definition of sepsis(1914): "Sepsis is present if a focus has developed from which pathogenic bacteria, constantly or periodically, invade the blood stream in such a way that this causes subjective and objective symptoms.”
“Therapy should not be directed against bacteria in the blood but against the released bacterial toxins”
ROGER C. BONE (1941-1997)
Helped develop the multi-disciplinary subspecialty of modern Critical Care Medicine
Promoted evidence-based approach to sepsis
"Sepsis is defined as an invasion of microorganisms and/or their toxins into the bloodstream, along with the organism's reaction against this invasion.“ (1989)
EPIDEMIOLOGYSepsis > 200,000 deaths/year in the USIncidence is > 700,000/ annumMortality for septic shock – 30% die within
first month & 50% dying within 6 months of diagnosis
Rising incidence of severe sepsis :1.Aging of the population2.Longevity of patients with chronic diseases3.Increase in people with AIDS4.Widespread use of antimicrobials,
immunosuppressives, indwelling catheters, mechanical ventilation
1344 admissions in ICU
Regional data
SURVIVING SEPSIS CAMPAIGNIn 2002, spearheaded by the ESICM (European Society of Intensive Care
Medicine), ISF (International Sepsis Forum) and SCCM (Society of Critical Care Medicine)
Aim : improving the diagnosis, survival, and management of patients with sepsis by addressing the challenges associated with it.
TERMINOLOGY
