In cases of acute mastitis, the specific situation must be considered. If it is a simple case of acute mastitis without a significant abscess, without particularly high white blood cell counts, and without pronounced fever, then it is not necessarily required to administer IV fluids. Local applications of magnesium sulfate compresses can be used, and in colder weather, these can be heated for a warm compress. Alternatively, traditional Chinese medicine such as Jin Huang powder can be applied externally and is often sufficient to resolve the issue. However, if the acute mastitis is accompanied by an increase in neutrophilic leukocytes, which requires verification through blood tests, and systemic symptoms such as fever and pain, then antibiotic treatment is necessary, typically administered through IV or orally, though IV is often faster. When acute mastitis is complicated by a breast abscess, not only is IV treatment needed, but also procedures for abscess drainage or incision and drainage. Currently, many minimally invasive methods for draining abscesses and other treatments are employed.
