Tissue Handling + Suture Patterns Flashcards
Who is William Stewart Halsted?
Human surgeon; came up with the basic principles of aseptic surgery
What are the seven Halsted’s principles?
Strict asepsis Good hemostasis Decreased Dead Space Minimize tissue trauma Maintain blood supply Avoid too much tension Apposition of tissue
What are the three types of biomaterials?
Suture + Metals/alloys + Polymers
What happens with physical-induced response w/ polymers?
Fibrous tissue formation
What happens with chemical-induced response w/ polymers?
Acute but mild inflammatory response or chronic response
What is the ideal response to polymers?
Minimal, thin layer of fibrous tissue
What are the four big things that suture materials need to be?
Non-electrolytic
Non-capillary
Non-allergenic
Non-carcinogenic
What are the three ways to classify sutures?
Degradable + Composition + Filaments
What is the strength of the wound dependent on?
Ability of the tissue to hold the suture
How strong should the suture be?
As strong as the tissue you are placing it in
Why is elastic suture material good?
to give room for edema
If wound is under tension what is the best method to handle it?
Increase suture number not size
What is important to do with the knot in a simple interrupted?
Offset
What determines the distance from the incision that you will place your simple interrupted?
Thickness of skin
What is one problem you can get with simple interrupted?
Too much tension leads to wound inversion
