difference between sharp and blunt dissection
sharp dissection: using scissors, scalpel etc
blunt dissection: cleaving soft tissues apart, eg using mosqiito forceps
what is diathermy
a medical and surgical technique involving the production of heat in a part of the body by high-frequency electric currents, to stimulate the circulation, relieve pain, destroy unhealthy tissue, or cause bleeding vessels to clot.
types of diathermy, describe each and potential problems
- monopolar (coagulation or cutting): charge in to patient and out through remote plate. BUT stimulates other muscles, nerves in pt at the same time
- bipolar: charge moves from 1 side of forceps to the other. much more common
3 main categories of suture and types of each
- absorbable: dexon (polygycolic acid), vicryl (polyglactin)
- slowly absorbed: PDS (polydioxanone)
- non-absorbable: silk, nylon, polypropylene
why is silk not often used for sutures
irritant
