NEW YORK (Reuters Health) – An advanced bandage that generates mild electrical current can help heal wounds four times faster, according to a recent study.
Researchers at the University of Wisconsin-Madison tested the electronic device on the body of mice suffering from back injuries.
With each mouse breath, an electric pulse is generated that speeds up the healing process. Skin healing cells, called fibroblasts, enter the infected area, promoting the production of collagen and new skin cells.
Electrophysiological stimulation was recognized as an accelerator of wound healing for the first time in the 1960s, in order to reduce swelling, increase blood flow and stimulate new tissue growth.
Once the personal domain was established, the researchers tested it on groups of mice with 1 cm of lesions on the back. Two days later, the mice were cured with "complete" closure of the wound within 3 days.
It should be noted that the low level of electricity generated means that the rodents showed no signs of pain or discomfort.
The researchers hope that a similar device will be used someday to improve healing of smallpox and acne scars. They say that existing methods to promote healing, such as dressings and oxygen therapy, are generally less effective.
