Postpartum blood accumulation in the uterine cavity usually does not need to be cleared if there is no residual tissue. If there is a lot of blood in the uterine cavity after delivery, you can use uterotonin under doctor’s supervision, breastfeeding diligently to promote uterine contraction, and appropriate activities to help the blood to be discharged slowly. If there is residue in the uterine cavity, such as retained placenta or membranous tissue, uterine evacuation may be necessary. After delivery, if there is residue in the uterine cavity and at the same time there is more vaginal bleeding, it is necessary to remove the residual tissue in the uterine cavity in time, which is conducive to uterine contraction, reducing bleeding and preventing postpartum hemorrhage. In addition, attention should be paid to checking the placenta and fetal membranes after delivery to prevent uterine cavity residue. Postpartum also need to pay attention to the vaginal bleeding situation, if the bleeding is more, to find out the reason in time. Meanwhile, you need to pay attention to enhance nutrition after delivery to help your body recover.
