Wound Healing/Management Flashcards
1
Q
Obj: Understand the predominant cellular events that occur in each phase of wound healing
A
- Decreased requirement for inhalation anesthetics
- improved muscle relaxation
- Preemptive analgesia
2
Q
Obj: Understand how our interventions, medicine, bandaging, ancillary therapies must change to meet the needs of the wound healing environment
A
3
Q
What are some important facts to remember about wound healing?
A
- all wounds heal by the same processes
- Consequences of healing depend on the function of the injured part
4
Q
What are the stages of healing in surgical wounds?
A
- Traumatic inflammation
- Destructive phase
- Proliferative phase
- Maturation phase
5
Q
how are the phases of wound healing differentiated?
A
- ID by the predominant cellular events
6
Q
What happens during the Traumatic inflammation phase of healing?
A
- Lasts 0-3 days (or longer w/ poor management)
- Physiologically:
- Increased blood flow
- vasodilation - mast cell + Histamine, Seratonin
- Increased Capillary permeability
- allows prostaglandins and leukotrienes
- Exudation and wound edema
- Fibrin deposition
- Increased blood flow
7
Q
What is the Starling Equation? How can it be altered? how does a bandage alter it? How would NSAIDS?
A

8
Q
What surgical techniques influence the inflammatory response?
A
- Strict Asepsis
- Preservation of blood supply
- Obliteration of dead space
- Careful approximation of tissues
- Accurate hemostasis
- Absence of tension
- Gentle tissue handling
