Endometritis, as the name suggests, is the inflammation of the endometrium caused by pathogens, so it is necessary to use sensitive antibiotics for treatment. Endometritis generally manifests as purulent vaginal discharge, or an increase in purulent bloody discharge, tenderness in the uterine body, accompanied by increased temperature or slight fever. For endometritis, choosing a vaginal secretion smear or bacterial culture and drug sensitivity test, and using the corresponding sensitive antibiotics for infusion therapy, results in better outcomes, to avoid the progression to chronic pelvic inflammatory disease.
