Guest guest Posted May 31, 2001 Report Share Posted May 31, 2001 Would anyone please be willing to share what electrical stim parameters you use for wound care? We see pressure decubiti and wounds secondary to diabetes. Thank you. Fern Striffler, PT Quote Link to comment Share on other sites More sharing options...
Guest guest Posted May 31, 2001 Report Share Posted May 31, 2001 Parameters we use: Frequency = average around 100 pps (128 for stage 111/WV ulcers and 64 for stage II) Amplitude = 75 - 200 V Pulse duration 60 - 100 microseconds Intensity - submotor sensory Duration = 45 - 60 minutes 3-5 days a week Polarity - Negative polarity bacteriocidal (used with inflammation or infection); it causes pH changes and attracts neutrophils It helps to soften eschar Promotes increased circulation (stimulates granulation tissue formation) Positive polarity Attracts neutrophils and macrophages for autolytic debridement (but is not intended to have the same effects with inflammation or infection) Attracts epidermal cells to promote wound resurfacing Repels mast cells SO: you have a patient come into your clinic - the wound is inflammed, could be infected. You decide to use high volt on (-) polarity. A couple of days later, the wound STILL has necrotic tissue present, but there are no signs of inflammation or infection, you switch to (+) polarity. Once the wound is clean and you need to promote granulation, you switch to (-) polarity. As the wound fills in and you need only to epithelialize, you switch back to (+) polarity (of course, you could stop HVPC at any point in this process).
