Question 7

What are good dressing options for wound infection?

Answer 7

avoid occlusive… rebandage daily… can use gauze, alginate, semipermeable foam

Question 8

What are the e-stim parameters for wound care? Direct, Immersion, Periwound

Answer 8

Frequency: 80-115 Hz
Intensity: 75-200 V (submotor)
Interpulse Interval: 50-100 microsec
Active cathode for infected
Active anode for granulation/epithelialization
Time 45-60 min
Frequency 3-7 days/wk

Question 9

What are the ultrasound parameters for wound care? Direct, Immersion, Periwound

Answer 9

Frequency: 3.0 for superficial, 1.0 for deep
Intensity: .5-1.0 pulsed, continuous

Question 10

What are the ultrasound parameters for wound care? Noncontact low frequency

Answer 10

Frequency: 25-40 kHz
Time: 20-60 sec be cm2, minimum of 4 min for wounds

Question 11

What are the hyperbaric oxygen parameters for wound care?

Answer 11

100% oxygen at 1.5-2.5 ATM
90-120 min
2x/day 3x/wk
10-60 sessions
if not 50% decrease in 10 treatments, wound is unlikely to respond
