What is oscopy?

Examination of a hollow viscus

1

Orraphy?

Repair of tissues

2

Ostomy?

An artificial communication between a hollow viscus and the skin

3

Otomy?

Cutting open

4

Plasty?

Reconstruction

5

Pexy?

Relocation

6

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

7

Good incision takes into account:

Good access
Orientation of skin tension lines
Strength and healing potential of the tissues
Anatomy of underlying structure
Cosmetic considerations

8

What are the principles of haemostasis?

Clipping, ligation under running water
Diathermy (electrically induced heat)
Tourniquet and exangination
Pressure
Hypotension anaesthesia

9

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.

10

What are the different types of suture material?

Absorbable
Slowly absorbed
Non absorbable

11

What are the common skin closure techniques?

Simple interrupted sutures.
Vertical mattress sutures.
Skin staples.
Subcuticular sutures (used for cosmetic appearance)

12

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.

13

What are dressings for?

To maintain the wound in a moist state.
To absorb or contain any superficial bleeding or inflammatory exudate.
To protect delicate healing tissue.
To apply pressure to prevent haematoma.
To conceal wounds from view.
