Encouragement of early post-partum mobility, especially after caesarean section, facilitates the drainage of blood from the uterine cavity; encouragement of breastfeeding stimulates the release of endogenous oxytocin, which promotes uterine contraction; and may be supplemented by medication. The blood is in a hypercoagulable state after delivery and is prone to thrombosis. Especially for cesarean section mothers with elective surgery, the uterine opening is not open, and the blood in the uterus is not easy to flow out of the uterus when they are lying in bed after the surgery. Therefore, encourage the mothers to leave the bed as early as possible after delivery to facilitate the discharge of the evil discharge, promote physical recovery and uterine contraction, and prevent the formation of thrombus, especially for fat mothers. Encourage the baby to suckle the breast as early as possible and frequently as effectively as possible, especially in the 3 days after delivery. Although there is not much milk, it is colostrum, which is the baby’s first vaccine in the world, and it is very valuable! When the baby sucks on the breast, it can stimulate the release of oxytocin in the body and promote uterine contraction, so the mother will often feel that when the baby sucks on the breast, there will be pain in the lower abdomen, accompanied by a small amount of vaginal bleeding. Therefore, insisting on exclusive breastfeeding is the best way to promote uterine contraction. When the uterus does not contract well after delivery, it can be supplemented with hysteronin. If there is a lot of bleeding after delivery, you can use hysteronin 20 units intravenously once a day or intramuscularly injected hysteronin twice a day, 10 units each time to promote contraction. Poor uterine contraction after delivery can also be supplemented with proprietary Chinese medicines, such as motherwort capsules or granules, biochemical soup pills, etc. Commonly used traditional Chinese medicines, such as biochemical soup, whose medicines include Angelica sinensis, Rhizoma Ligustici Chuanxiong, peach kernel, roasted licorice, etc., and usually can be added with some hawthorn, Citrus sinensis, etc., which are shown to have a role in promoting uterine contraction in pharmacological research. Therefore, poor uterine contraction after delivery can be promoted through appropriate activities, breastfeeding, supplemented by Chinese and Western medicines, while at the same time pay attention not to be too strenuous.
