METHOD OF TREATING VAST PURULENT WOUNDS OF SOFT TISSUES Russian patent published in 2010 - IPC A61N5/67 A61K31/409 A61K31/717 A61K31/765 A61P17/02 

FIELD: medicine.

SUBSTANCE: invention refers to medicine also can be used for treating vast purulent wounds of soft tissues. That is ensured by exposure of a wound surface to high-energy semiconductor lasing after opening of a suppurative focus and detritus evacuation. Then the wound is irrigated with an antiseptic and exposed to defocused CO₂-laser beam of power 20 Wt, light spot diametre 1 cm in the continuous mode. On the 2 day after the beginning of treatment, provided no secondary necroses observed, a session of photodynamic therapy follows. Herewith, the wound surface is coated with Photoditazine modified gel of methyl hydroxyethyl cellulose esters containing 0.5-1.5% dimethylglucamine salt of chlorine E6. Before applications, gel is mixed with 25% aqueous polyethylene oxide in the volumetric ratio gel: polyethylene oxide 10:2-3. Then it is exposed to semiconductor lasing of wave length 0.66±0.03 mcm, power density 0.5 to 1.0 Wt/cm² and energy density 20 J/cm². If detecting the signs secondary necrosis, before photodynamic therapy, the wound is processed with defocused CO₂-laser beam one more time. Another session of photodynamic therapy is required, when on the 2^nd day after photodynamic therapy, perifocal inflammatory manifestations remain in the wound.

EFFECT: method allows preventing development of secondary necroses and growth of residual microflora in the purulent wound, stimulating reparative processes, reducing length of treatment of vast purulent wounds and pyoinflammatory diseases of soft tissues.
