Mupirocin ointment can be used to treat abrasions, but it is important to be clear that the purpose of mupirocin for the treatment of abrasions is not to promote tissue healing, but to prevent wound infection. Because tissue abrasions are usually superficial skin as well as subcutaneous soft tissue injuries, they are prone to small amounts of oozing blood and exudate as the abrasion may be accompanied by skin breakage. At this time, timely cleaning and disinfection is required, otherwise the oozing blood and exudate can be used as a good bacterial medium, and there are a large number of bacteria in the external environment, which can easily grow and multiply in it and lead to bacterial infection. So for superficial abrasions, you can disinfect with iodophor in time and use mupirocin ointment after disinfection. Because mupirocin ointment as a kind of antibiotic drugs, can play a role in killing bacteria, so as to prevent wound infection. Therefore, mupirocin ointment can be used to treat abrasions, but its purpose is to prevent secondary bacterial infections, not to promote wound healing.
