Opraclean dressing materials help cleanse wounds by absorbing wound exudate, cell debris and bacteria. Opraclean works very well for packing even deep wound pockets and cavities. At the same time, the iodoform-saturated dressings exert an antimicrobial effect. When it comes in contact with wound secretions, iodoform breaks down and releases small amounts of iodine from the dressing. Iodine is known for its broad therapeutic spectrum of action against numerous gram-negative, gram-positive, aerobic and anaerobic bacteria, as well as against fungi and viruses. One more advantage: there is no known pathogen resistance to iodine.
