Excessive bleeding depends on what part of the body is causing the bleeding and the amount of bleeding. If a female patient has excessive menstruation and excessive menstrual bleeding, she may not need to worry too much for the time being. She needs to observe the changes in her vital signs, whether she has dizziness or nausea, and can go to the hospital for examination and check the blood count to see if there is any anemia. If the decrease in hematocrit is not very obvious, you can continue to observe. If it is nosebleed and bleeding excessively, you can try to use conservative treatment first, such as cold compresses, if the bleeding does not stop, you need to come to the hospital for treatment. If there is excessive bleeding from the intra-abdominal drainage tube after surgery, first observe the patient’s vital signs and the color of the drainage tube. If the vital signs are stable and the rate of bleeding is not very fast, conservative treatment can be continued. If the bleeding rate is very fast, bleeding 400 ml per hour or even 500 ml or more of bright red blood, another operation may be required.
