Joe + Sathya Flashcards
(30 cards)
Are hands sterile?
no they are aseptic
What is asepsis?
absence of microbes that cause disease
What is surgically clean?
destruction of all accessible microorganisms on the surface
What is contaminated?
a surface or structure where microbes are present
When is an infection considered a surgical infection?
30 days after regular surgery, 1 year after implant
HOw does anesthesia enourage infection?
hypotension and hypothermia decrease perfusion and reduce defence against infection
How much does each hour increase infection chance?
30%. higher risk for contamination and more suppressed immune system
How much does each hour increase infection chance?
30%. higher risk for contamination and more suppressed immune system
What % of gloves have holes to start? after surgery?
1.5% before, 26% after.
What % of gloves have holes to start? after surgery?
1.5% before, 26% after.
What are adhesions?
scar tissue that forms between organs and tissue after an abdominal surgery.
why aren’t small animals prone to adhesions?
they have an active fibrolytic system
What causes adhesions
fibrin deposition after an abdominal inflammatory response.
Most common reason to get a horse back in sugary?
adhesion
Most common reason to get a horse back in sugary?
adhesion, specifically small intestine lesion adhesions (which cause death)
What are the risk factors for adhesions?
SMALL INTESTINAL LESIONS! prolonged post-op ilius Repeated exploratories Young animals peritonitis and abscesses inflammation ischemia foreign material Tight sutures Intestinal distention
What are the risk factors for adhesions?
SMALL INTESTINAL LESIONS! prolonged post-op ilius Repeated exploratories Young animals peritonitis and abscesses inflammation ischemia foreign material Tight sutures Intestinal distention
Adhesion formation is the balance between:
coagulation and fibrinolysis - if we increase coagulation (as in inflammation) we decrease fibrinolysis
what factor breaks down fibrin?
Tissue plasminogen activator (TPA)
When do adhesions become permanent (fibrer)
1-2 weeks after surgery.
Which adhesions rarely cause clinical problems
fibrinous, omental,
which adhesions cause clinical problems?
fibrous adhesions
Adhesions: omentum, intestine to mesentary/peritoneium, intestine to intestine, multiple intestine to intestine. Rank from worst to best.
ometum, intestine to peritoneum, intestine to intestine, multiple. (massive fiberous)
How do you prevent adhesions?
minimize inflammation, enhance fibrinolysis, stimulate intestinal motility.
