Numerical Rating Scale(NRS).

ObjectiveTo analyze the efficacy and safety of dexamethasone in the treatment of non-puerperal mastitis (NPM), providing a new idea for the treatment of NPM.MethodsFrom August 1, 2017 to August 30, 2024, case data were collected from 552 patients with NPM. After grouping according to different treatment options, the SPSS statistical software was used for retrospective analysis of the collected data.ResultsThe number of days of drug treatment before operation in group B was less than other groups (p 0.05).The side effects of nausea (vomiting) and skin pigmentation in group E were higher than other groups(p ConclusionDexamethasone combined with levofloxacin/Metronidazole in the treatment of NPM has many advantages: first of all, it can significantly relieve the pain symptoms caused by the disease and effectively reduce the size of the lesion. Meanwhile, for the patients who plan to undergo surgery, the number of days of preoperative drug treatment can be reduced, and the overall effective rate is the highest. Secondly, the short-term application of drugs to treat side effects less, high safety; in the meantime, the risk of recurrence of the ipsilateral breast was less and the satisfaction of the patients was higher. The overall significant efficiency and recovery rate of GLM patients were higher than those of PCM patients.
