New drug ambipor that is an immobilized antibacterial agent with local prolonged therapeutic activity was developed for prophylaxis of wound suppuration. In ambipor A drugs gentamicin, dioxidin, kephzol and riphampicin are immobilazed, in iodopor - iodine. Experimental studies on 455 white rats showed that ambipor prevents suppuration, abscess formation around ligatures, improve regeneration and fibrillogenesis. In clinical practice ambipor A and iodopor were used in 562 patients. Rate of suppuration decreased from 11.7 to 2.3% compared with control group of patients.
