Similarly, patients with diabetes who are taking sulphonamides or sulphonylureas, which inhibit thyroid hormone synthesis, should be observed for possible toxic effects and it may be necessary to check their thyroid hormone levels.
Severe cutaneous reactions are rare, but nurses should always stop using iodine if they occur. There is no strong evidence that products that contain PVP-I pose any hazard to wound healing, but because of its broad antimicrobial properties it appears that it may play an important role in the prevention and treatment of wound infection Mayer and Tsapogas, Iodine is diluted and can soon be broken down if it comes into contact with exudate and proteins on the wound surface.
This reduces any long-term effects it may have. The benefits of PVP-I generally last for a few hours, but subsequent dilution usually makes it necessary to change dressings at least once a day.
PVP-I is therefore recommended for use on infected wounds with low levels of exudate and wounds that need frequent dressing changes. Cadexomer iodine is a three-dimensional starch lattice formed into spherical microbeads containing 0. These beads are highly absorbent and the pores of the lattice increase in size when they are exposed to exudate, allowing the gradual release of iodine Sundberg and Meller, All three proprietary forms of cadexomer iodine are made up of the same formulation and are available as a powder, paste dressing or ointment Thomas and Leigh, The slow release of the iodine in these preparations allows the wound to remain in continuous contact with it, whereas with a single exposure to a product such as PVP-I tulle the iodine is soon broken down Sundberg and Meller, The beads also absorb debris and can therefore be used to remove it from the wound bed, making cadexomer iodine a useful debriding agent.
In a study of 28 patients with venous leg ulcers, Steele et al found that it was effective in dirty, odorous ulcers and Apelqvist et al found it useful in controlling exudate in diabetic foot ulcers.

Even though these treatments have been passed down through the generations, experts caution against these and many other DIY home remedies for treating wounds. A recent article by the Los Angeles Times got the input from Dr. The use of hydrogen peroxide on wounds seems logical at first: the bubbling action removes debris from the wound that could potentially lead to an infection.
However, experts agree that hydrogen peroxide is too harsh and irritating for an open wound. According to wound specialist Dr. Rubbing alcohol, or isopropyl alcohol, it a topical antiseptic. Betadine, also known as povidone-iodine PVP-I or iodopovidone , is an antiseptic used for skin disinfection before and after surgery. Betadine works by releasing iodine which results in the death of a range of microorganisms. Hence, iodine deserves to retain its place among the modern antiseptic agents.
