What disinfectant is usually used for babies is a frequent problem for parents. Iodine volts are relatively less irritating, so newborns are generally treated with iodine volts instead of alcohol for umbilical cord disinfection. One disadvantage of iodophor is that it can easily cause local pigmentation, so alcohol is generally used for disinfection of the face instead of iodophor. For special areas such as the perineum, which is more sensitive, it is recommended to disinfect with diluted iodophor by doubling the iodophor and then doing local disinfection, and alcohol can be used for skin disinfection before intramuscular injection.
