Erythromycin ointment is a commonly used antibiotic ointment in clinical practice. Erythromycin ointment can be applied externally to wounds that are clearly infected. In fact, the vast majority of traumatic wounds in clinical practice do not have an obvious tendency to become infected, and there are many patients who, after regular disinfection and dressing, can quickly undergo a relatively good healing process, and the wounds are often relatively clean and fresh. The application of erythromycin ointment for external rubbing at this time may not significantly help the healing of traumatic wounds. Therefore, it is not recommended that patients apply erythromycin ointment to routinely apply with trauma, but of course, if you want to promote wound healing, you can apply drugs such as recombinant human epidermal growth factor gel.
