Absorbable threads cannot be soaked off by iodophor. The main components of iodophor are simple iodine and polyvinylpyrrolidone, which are mainly used for sterilization and disinfection. Iodophor can kill bacteria, fungi and some viruses. It has a wide range of disinfection effects and can be used for pre-operative skin disinfection of patients, disinfection of skin areas during mucosal disinfection injections, and disinfection of gynecological procedures. The use of iodophor is more acceptable to patients than the use of alcohol because it is much less irritating than alcohol, and the absorbable thread is a new type of surgical suture material. After being sewn into the body, it can be absorbed by the body on its own, so that the stitches do not need to be removed at a later stage and the patient does not have to suffer from the pain of stitch removal, and it is now widely used.
