Bacterial vaginitis cannot be aborted. Bacterial vaginitis is a mixed infection caused by the decrease of Lactobacillus in the vagina and the increase of Gardnerella and other anaerobic bacteria. Whether it is an early abortion or a medical abortion, the uterine opening has to be dilated and the dilated uterine cavity is connected to the vagina. At this time, if there are pathogenic bacteria in the vagina, they may enter the uterine cavity and cause artificial retrograde infection. The treatment of bacterial vaginitis is still relatively simple. Generally, anti-anaerobic drugs are used, mainly metronidazole, tinidazole, clindamycin, etc. Metronidazole can inhibit the growth of anaerobic bacteria without affecting the growth of lactobacillus, which is a more ideal treatment drug. The procedure can be performed only after a course of medication and a review of the routine leucorrhea indicates normal.
