The common reasons for unclean postnatal discharge include lack of uterine contraction after delivery, resulting in the placenta or meconium and other tissues failing to be completely discharged. Infections in the uterine cavity caused by early pelvic bathing, sexual intercourse or the use of unclean sanitary napkins, and weak uterine contractions after delivery are recommended to inject intramuscular or intravenous hysteronin to promote uterine contractions and promote the complete expulsion of the placenta and meconium. For infection-induced failure to cleanse, it is recommended that cephalosporins, quinolones and tinidazole be fed intravenously for anti-infective treatment, which needs to be used continuously for about 5-7 days, and about 10-15 days for severe symptoms. During the period of treatment of postnatal discharge, it is recommended to take a light diet, avoid eating hot, spicy and stimulating food, so as not to aggravate the symptoms of postnatal discharge. During the period of discharge, it is recommended to wash the vulva every night and pay attention to personal hygiene.
