In general, a 1g drop in hematocrit results in about 400-500ml of bleeding in the body, because hematocrit is hemoglobin, which is normally 12-16g/L for adult males and 11-15g/L for adult females, so a 1g drop in hematocrit results in about 400-500ml of bleeding. Because of this, the patient’s blood loss can often be roughly judged by the degree of the patient’s hematocrit drop. For example, if an adult woman has ruptured bleeding from ectopic pregnancy and her hematocrit drops to about 6g, the patient’s blood loss is roughly judged to be about 2400ml, which is prone to severe hypovolemia, leading to hemorrhagic shock and even threatening the patient’s life. The most effective way is to give active blood transfusion treatment, and at the same time, find the ruptured fallopian tube through surgery and give it a repair. After the fallopian tube is repaired, the bleeding stops and the patient’s life can be saved through massive blood transfusion.
