Poor contraction of the uterus refers to the clinical manifestations such as malignant dew and bleeding as a result of the uterus not regenerating properly after abortion or delivery. After the delivery of the fetus, the uterus will generally contract strongly, and a hard mass shaped like a large triangle can be felt in the lower abdomen at this time, which is a better contracted uterus. The contraction of the uterus is not good due to long labor and fatigue, and the uterus is soft and large to the touch from the lower abdomen. Due to the heavy bleeding, the mother often has acute symptoms of blood loss such as indifference, pallor, poor mental health and weakness. In order to avoid excessive accumulation of urine in the bladder to affect the contraction of the uterus and prevent bleeding caused by poor uterine contraction, it is important to urinate within 4 hours after delivery, and family members can help massage the uterine body below the patient’s navel, which can effectively help the uterus contract. After abortion due to a long period of bed rest may also lead to accumulation of blood in the uterine cavity or the tissue left behind by the abortion may also lead to poor uterine contraction. Power therapy instrument or bioelectric stimulation pelvic floor therapy instrument and other devices have good effect on poor contraction of the uterus; in addition, injection of uterine contraction, taking motherwort punch and other drugs also have good effect on the treatment of poor contraction of the uterus.
