HISTORY OF WOUND CARE
A long and eventful history that traces its origins to ancient Egypt and Greece
The Ebers Papyrus, circa 1500BC, details the use of lint, animal grease, and honey as topical treatments for wounds - lint provided a fibrous base that promoted wound site closure - animal grease provided a barrier to environmental pathogens - honey as an antibiotic agent.
THE EGYPTIANS :
Ulcerating lesions were bound with figs containing papainWine, vinegar, and hot water were used to clean woundsAfter cleansing, dry powder consisting of a mixture of copper, mercury, zinc and silver were used to prevent inflammationSilver was used as an ingredient in plasters to cover open wounds, as well as to purify waterSeaweed, which contains iodine, was used for sunburns
THE ROMANS De Medicina written by Celcus ( 25 BC – 50 AC ) -- described the 4 fundamental signs of infection ( rubor, color, dolor, tumor ) & addressed the importance of wound cleansing“Clean the wound of old blood because this can
change into pus, which inhibits healing”
THE GREEKS
The first to differentiate between acute and chronic wounds, calling them "fresh" and “nonhealing” respectively
Claudius Galen of Pergamun (120-201 AD) , a Greek surgeon in the Roman empire discovered the importance of maintaining wound moisture to ensure healing of the wound
17th CENTURY :Invention of microscope by Anton von Leeuwenhook (1632-1723) of Netherland
19th CENTURY :Development of MICROBIOLOGY & PATHOLOGY
Ignaz Philipp Semmelweis ( 1818-1865), a Hungarian obstetrician developed sterile surgical procedures using chlorinated lime solutions Louis Pasteur ( 1822-1895), a French scientist known as the “father of microbiology” --- “Germ Theory Of Disease”
Rudolf Virchow ( 1821-1902 ) of Germany discussed his ideas on formation, proliferation and regeneration of cells
PROGRESS BEYOND ANCIENT WOUND CARE PRACTICES IS A RECENT PHENOMENON
EARLY 20th CENTURY
20th CENTURY & THE WARS :
Surgeons used full-strength phenol in war patients developing gangrene due to infections
French surgeon Alexis Carrel ( 1873-1944) from New York & who was awarded the Noble Prize for Physiology & Medicine in 1912, bathed wounds in Dakin’s Solution
[ Sodium Hypochloride + Boric Acid ]
1 month before introduction of Dakin’s Solution, Professor J Lorraine Smith introduced Edinburgh University Solution Of Lime ( EUSOL), ), [[chlorinated lime + boric acid ] for use in wounds of war soldiers
Davies, a physician in Hertford, used iodine solution to disinfect wound in 1839 which was used extensively during American Civil War ( 1863) and WW1 to treat wounds and to scrub hands before surgery
Nevertheless, iodine disinfection failed to gain general acceptance till 1870s when French bacteriologist Casimir Davaine ( 1812-1882) confirmed that iodine solution could kill a wide variety of micro-organisms
In 1878, iodoform was introduced as a hospital disinfectant by Apollinaire Bouchardat, a pharmacist in Paris
William Stewart Halsted (1852-1922) : silver foil dressing for infected wounds which were used extensively during
WWII
Chlorhexidine was discovered in 1946 & introduced into clinical practice in 1954 for washing hands and as surgical scrub
Other antiseptic used included alcohol, hydrogen peroxide, hexachlorophene, thimerosal, gentian violet and permanganet
After the war, in vitro research indicated that these substances were cytotoxic to human cells and have adverse effects on wound healing
The discussion on the toxicity of these agents, started by Alexander Fleming in 1914, still continues today, almost 100 years later
1968, Dr Charles L Fox Jr, a bacteriologist in Columbia University combined silver nitrate and sulfadiazine to create a synergistic compound that is extremely effective against infection
Silver sulfadiazine (SSD) quickly became the drug of choice due to its effectiveness at controlling bacterial infection and pain-free application.
It was used extensively during the Vietnam War Since then, various silver-coated dressings which use
metallic silver, ionic silver etc combined with various carriers ( polyurethane, alginates, carboxymethyl cellulose, knitted fabrics ) were gradually introduced

WOUND CARE NOT A PART OF MEDICAL SCHOOL CURRICULUM ---- not before and not even now !
DOCTORS ARE EXPECTED TO LEARN ON THEIR OWN
Most have no idea HOW TO DO IT, WHAT TO USE, WHEN TO DO WHAT
Majority just “DO IT THE WAY IT HAS BEEN DONE OVER THE YEARS” or just “LEAVE IT TO THE NURSE”
MODERN WOUND CARE
EVIDENCE-BASED
Convert dirty to clean woundHealing without infectionHealing without painRapid healing Cost-effective wound management
Combining your experience, patient’s situation and the best scientific evidence

Autolysis is a natural process, uses the body own enzymes. Autolysis as a selective type of debridement.Gently rehydrates dry and softens necrotic tissue and sloughProvides moist wound healing environment
The use of topically applied enzymatic agent to stimulate the break down of non-viable tissue.
Faster debridement compared autolytic
Painless and less bleeding.
Does not effect intact epithelium, granulation tissue, fatty tissue or muscle.

Slow release Slow release iodine: kills iodine: kills bacteria / prevent bacteria / prevent infection (broad infection (broad spectrumspectrum))
Used for centuries to prevent and treat infection
Reduces the risk of colonization and acts to kill micro – organisms which can cause infection and prevent or retard healing
Broad spectrum – inactivates almost all known bacteria including MRSA and VRE
Silver is first choice antimicrobial dressing.
