[The significance of low-frequency magnetotherapy for local treatment of burns. An experimental comparative approach (author's transl)].

Under standardized experimental conditions 3rd degree burns were produced on the neck of 241 Wistar-rats. The process of wound-healing was documented by means of planimetric, histologic and microbiologic methods. In comparison to an untreated control-group the effectiveness of low-frequency magnetotherapy (system magnetodyn 5 by W. Krauss) as well as coagulation of necrosis according to Grob and autologous skin-transplantation were studied. The results obtained indicate that only early debridement of necrosis and subsequent autologous skin-grafting guarantees sufficient acceleration of wound healing. The low-frequency magnetotherapy according to Krauss showed no effect of therapeutic value. With the coagulation of necrosis, as described by Grob, a germfree status under the necrosis was obtained for nearly 2 weeks.
