A little bit of nightmare is not clean, first of all, we should observe the duration of nightmare, the normal duration of nightmare is 4-6 weeks, if it is not long, it may be normal nightmare discharge. If the nightmare lasts for a long time, or continuous bloody nightmare is abnormal, it may be caused by puerperal infection, lack of uterine contraction, poor healing of the incision, etc., and can be treated after clarifying the cause. 1, puerperal infection: puerperal infection, wound healing in the reproductive tract is slow, manifested as a little bit of nightmare is not clean, but also accompanied by odor and color change of nightmare, abdominal pain, fever and other symptoms. The symptoms may include odor and color change, abdominal pain, fever, etc. The diagnosis can be clarified through vaginal discharge and blood tests, and targeted treatment can be carried out after identifying the causative microorganism and the site of infection. In case of secondary puerperal infection caused by residual necrosis of the placenta and fetal membranes, oral uterine shrinkage drugs combined with anti-infective drugs can be used to treat the problem. 2. Lack of contraction of the uterus: lack of rest, multiple births, scarring of the uterine wall, etc. can lead to lack of contraction of the uterus and slow discharge of malodex, which is manifested as dripping malodex. After the diagnosis is confirmed by abdominal ultrasound and gynecological internal examination, oral or intramuscular injection of uterine contraction drugs can be used. At the same time, appropriate breastfeeding, sucking of the baby’s nipple and massage of the uterus can stimulate uterine contraction and accelerate the discharge of malodex; 3. Poor healing of the incision: When the wound formed by the damage to the reproductive tract during labor heals poorly, the blood flowing out of the vagina is similar to the discharge of malodex. If the amount of bleeding is small, you can use hemostatic and anti-inflammatory drugs and observe the changes in the amount of bleeding temporarily. If the bleeding is heavy, surgical stitches and oral hemostatic and anti-inflammatory medications may be required. It is important to pay attention when you find that a little bit of malodex is not clean. If it is caused by puerperal infection and is not treated in time, it may cause local and systemic infections, and in serious cases, sepsis may occur. At the same time, we should pay attention to care, prevent the infection from worsening, and exercise properly to speed up the discharge of malodorous fluid.
