A

about 1 month after graft

32
Q

How do you treat hypertrophic scarring

A

Pressure garments 25 mmHG

takes 6 months - 2 years to mature

33
Q

Describe the physiologic effects of Estim for wound healing

A

Attracts reparative cells
Modifies cell membrane permeability
Restoration of cell structures
Jump starts wound healing

34
Q

What polarities are indicated for the different phases of healing

A

Inflammatory: + for macrophage activity, - for inflammation reduction
Proliferative: - for increased fibroblast activity
Maturation / remodeling: + for decreased scar thickness and decreased mast cells

A

Monopolar

39
Q

Describe diathermy

A

increase tissue temperature
Autolytic debridement
