Flashcards in Principles Of Operative Surgery Deck (14)
What is oscopy?
Examination of a hollow viscus
Repair of tissues
An artificial communication between a hollow viscus and the skin
Surgical access, incisions and management of wounds:
Only shave if necessary.
Skin prep 0.5% chlorhexidine in 70% alcohol
Double thickness linen sheets
Disposable fabrics allow less penetration
Good incision takes into account:
Orientation of skin tension lines
Strength and healing potential of the tissues
Anatomy of underlying structure
What are the principles of haemostasis?
Clipping, ligation under running water
Diathermy (electrically induced heat)
Tourniquet and exangination
What are the three modes of diathermy?
1. Coagulating monopolar diathermy: bleeding point is picked up by diathermy forceps and coagulates. Current flows through patients body.
2. Cutting monopolar diathermy. Current passes through patients body.
3. Bipolar diathermy: current flows down one blade of forceps through tissue between blades and up the other side.
What are the different types of suture material?
What are the common skin closure techniques?
Simple interrupted sutures.
Vertical mattress sutures.
Subcuticular sutures (used for cosmetic appearance)
What's the excision technique for removing a cyst?
Incision extends beyond edge of lesion, plane of dissection around cyst by blunt dissection, remove cyst intact with overlying skin and then suture up the skin.
