If the cervix localized cryotherapy, the following matters should be paid attention to after the operation: 1, to keep the vulva clean, wash the vulva twice a day with a solution of 30% of the cleansing gel to avoid pathogenic bacteria infection. 2, in the second day after cryotherapy, due to the localization of a large amount of exudation, it will be manifested as an increase in the vaginal secretion. At this time, we must change the sanitary napkin diligently to avoid long time without changing the sanitary napkin, which will lead to the infection of pathogenic bacteria. 3, you can’t have sex for 3 months after the operation, because after the freezing, the cervix is gradually recovering, which will take 3 months. 4, you can’t take a sitz bath when you are taking a bath, and you should take a shower, to avoid the bath water entering into the vagina, which will lead to the infection.
