Treatment of Wounds Flashcards
How wound you initially prevent further contamination of a wound?
Fill with a water based ointment
Eg KY jelly, hydrogel etc
How can you minimise hair contamination into a wound?
Clip away from the wound edges!
What type of surgical scrubs must you avoid when initially preparing a wound?
Those containing detergents (cytotoxic)
What is meant by hydrodynamic debridement?
What are our aims in using this technique? (x5)
Lavage!
- Decrease the number of bacteria in the wound
- Remove debris
- Prevent further contamination
- Prevent development of an infected wound
- Make contaminated/clean-contaminated wounds fit for surgical closure
An optimum lavage pressure of 8psi can be achieve using which pieces of equipment?
19G needle
35 ml syringe
What concentration of povidone-iodine is toxic to fibroblasts?
>1%
Describe hydromechanical debridment.
Using a hydrogel causes hydration and sloughing of necrotic tissue. Also contains propylene glycol which is bacteriostatic.
Moisture also promotes cell migration adn proliferation
What features are used to assess tissue viability?
- Colour
- Pulse
- Bleeding
How woud you manage a wound reassessed as clean/clean-contaminated after initial management?
Primary closure - immediated suture without tension
How woud you manage a wound reassessed as contaminated/ not sure of tissue viability after initial management?
Delayed closure (after 1-5 days).
Lavage daily and assess granulation/ devitalisation of tissues
How woud you manage a wound reassessed as dirty/ contaminated after initial management?
Secondary closure >5 days old
Allow grandulation tissue to form they excise wound edges and close
Second intention healing
Healing without surgical interference
