RESUMO
Objective To study the hemostasis activity of iodine complex with carboxymethyl chitosan .Methods The polymers were prepared with azodiisobutyronitrile as the initiating agent and sodium acrylate ,N‐vinylpyrrolidone ,carboxym‐ethyl chitosan and N ,N′‐methylene diacrylamide as the raw materials .It was then complexed with iodine to generate iodine complex with carboxymethyl chitosan ,and the hemostasis activity was tested at the same time .Results The polymers could absorb water with the value of 103g/g and showed potent hemostasis activity for auricular veins and femoral veins .Conclusion The results showed that hemostatic effect of polymers was better than that of hemostatic sponge and Quikclot .
RESUMO
Maxillofacial gunshot wounds are usually contaminated with a large number of pathogenic microorganisms which are difficult to be cleared out thoroughly by the routine surgical debridement alone. In 12 dogs, we observed the effect of application of l% CIC in debridement on the infected gunshot wounds of the mandible contaminated with numerous different bacteria 72 h after gunshot. After the debridement of the routine method, bacterial cultures were positive in 10 of 12 dogs while all cultures were negative for the wounds treated with 1% CIC.We suggest that l% CIC, as a wound irrigating agent, is suitable for early debridement of the oral and maxillofacial injuries,especially for that of gunshot wounds.
