Longer or even puerperal infections are more harmful to the mother. What are the causes of abnormal body temperature? If the body temperature exceeds 38℃ twice in a row within 10 days after delivery, it is called “sick puerperium” (also called “postpartum sickness rate”), and timely consultation should be made to identify the causes in order to reduce the occurrence of puerperal infection. If the temperature continues to rise after delivery and is accompanied by redness, swelling and tenderness on the surface of the breast, it is a sign of breast infection (i.e. acute mastitis, mostly seen in first-time mothers) and should be treated promptly. What are the causes of abnormal malignant dew? Abnormal malignant dew can be a change in the duration and nature of malignant dew. If the uterus is poorly regenerated or if there is placenta or fetal membranes left in the uterus, there will be a lot of bloody malignant fluid and it will last for a long time. If there is a combination of infection, it can also manifest as purulent malodour with a putrid smell. The puerperium is a critical period for the recovery of the mother’s body after childbirth, and scientific menstruation is of great significance to the health care of both mother and child. I hope that through the above introduction to help mothers to sit correctly on the moon, both “sit” well, but also do a good job.
