Uterine hemorrhage is actually the category of obstetrics. There are many causes of uterine hemorrhage, including the inability of the uterus itself to contract, or abnormal coagulation caused by placental abruption or stillbirth, as well as more serious amniotic fluid embolism can cause uterine hemorrhage, and some intraoperative ligation or poor vascularity is also a cause. The occurrence of uterine haemorrhage first requires anti-shock treatment. Haemorrhage is considered to be massive if the amount of blood loss exceeds a certain value for a short period of time, such as 500ml or more. The solution to this situation is as follows: 1. First of all, the blood volume needs to be corrected and replenished; 2. Anti-shock treatment, if the effect is still not obvious in the case of rehydration, it is necessary to use some pressure-raising drugs, such as medical dopamine or norepinephrine can achieve the effect of pressure-raising; 3. The key is how to stop bleeding, and the first measure to stop bleeding is to replenish the clotting factor, because the patient often to the late stage will appear the clotting factor If these measures are not effective in conservative treatment, it is also necessary to consider whether to do hysterectomy to stop the development of DIC. In general, comprehensive treatment is needed. Only one hemostatic drug cannot achieve the effect, and general hemostatic drugs cannot achieve the effect of hemostasis, but some special treatment is needed.
