Saline and iodophor are two different substances with different roles and efficacy, so they cannot be compared, and there is no good or bad. When a wound is contaminated and needs to be cleaned, patients can choose to use sterilized saline. Saline can flush out dirt, wood chips, dust and other filth inside the wound, whether it is fresh or already infected, patients can use sterilized saline for flushing. Iodine volt has a strong anti-inflammatory and bactericidal effect, which can kill viruses and bacteria, but patients in the case of wounds that have been contaminated, it is recommended that it is best not to use iodine volt directly for disinfection, patients need to rinse with sterilized saline and then apply iodine volt, so as to play the role of anti-inflammatory and bactericidal, which can better promote wound healing.
