Electric Band-Aids
Omni, Unknown date (1983-1986 range, probably)
Electricity speeds up the rate at which broken bones knit. But what
would happen if you electrified a skin wound? That's the question
biochemist Oscar M. Alvarez and colleagues at the University of
Pittsburgh Medical School asked themselves recently. The answer: a
30 percent reduction in healing time.
The new procedure involves dipping a nylon cloth in silver, which
acts as an electrical conductant. The cloth is then connected to a
battery, energized with a tiny electric current, and placed on the
wound.
The Pittsburgh group treated minor surface abrasions on the skin of
several domestic pigs, and the results found that the electrified
wounds healed in an average of 2.9 days.
This compared with 4.1 days for wounds treated with the silver cloth
but without electricity, and 4.6 days for those wounds left open to
the air.
According to Alvarez, tests indicate that both silver AND the
electricity are responsible for the rapid healing. "It is fairly
apparent," he explains, "that the electrical-silver complex
stimulates cells from surrounding tissue to aggregate at the wound
site, increasing protein production and enhancing the healing
process."
Manufactured by the Sybron Corporation, the silver-coated bandage
has recently been classified as a drug (of course.. has as much to
do with drugs as, say, vitamins..).
Approval by the Food and Drug Administration should follow on the
heels of human tests, now being conducted by Dr. James Albright,
chief of orthopedic surgery for the St. Louis Medical Center, in
Shreveport, Louisiana. If all goes well, you'll find the bandages
on your pharmacy shelf in a few years. (Damn, I can't find them,
and its been a few years...) -Rick Boling
