Positive leucorrhea peroxide in pregnant women generally indicates a significant decrease of lactobacilli in the vagina of pregnant women, which may lead to an imbalance of vaginal micro-ecological balance and easy proliferation of pathogenic bacteria, thus causing vaginal inflammation, such as bacterial vaginitis, trichomonas vaginitis or mixed infections, which will increase the risk of infection or water breaking during delivery. Pregnant women may also experience increased leucorrhea with odor and vulvar itching, which should be treated with medication under the guidance of a doctor, not blindly on their own, to avoid adverse effects on the fetus. If a pregnant woman’s leukorrhea is positive for hydrogen peroxide, during vaginal delivery, bacteria or viruses inside the vagina may retrograde into the uterine cavity through the cervical opening, and the mother may have fever after delivery. In a woman who has given birth by cesarean section, bacteria from the vagina may also retrograde into the uterine cavity and cause pelvic inflammatory disease. Therefore, pregnant women found to have positive leucorrhoea peroxide must be treated actively. It can be treated with intravaginal application of nifurtimoxazole vaginal suppositories under the guidance of a doctor, paying attention to washing hands before using the medicine. The symptoms will be significantly improved after 1-2 weeks of treatment. You can stop the medication for 3 days and recheck the white belt routine again. You should also pay attention to the fetal heartbeat and fetal movement during the course of medication, and stop the medication in time if there is any abnormality, and visit the doctor for examination if necessary. Pregnant women should pay attention to the cleanliness of the vulva, you can wash your vulva with water every day, and wash and change your underwear regularly to reduce the breeding of pathogenic bacteria.
