How do doctors stop internal bleeding?

What is the most effective procedure when there is lethal amounts of internal bleeding within a patient?

Surgery. In most cases bleeding can be managed with administration of fluids, blood transfusions and correction of any underlying coagulopathy. However, some organs can bleed profusely if injured. If the spleen and its capsule are ruptured we do a splenectomy. If a lobe of the liver is lacerated we do a hepatic lobectomy. If a major vessel (aorta or vena cava) is bleeding we do an exploratory laparotomy and ligate/suture the bleed. If a non-vital organ like the urterus is bleeding they can also do embolization. This is where they go in with a catheter and artificially induce a clot upstream from the bleed. It leads to necrosis of the tissue and isn't ideal, but it can save the patient from bleeding to death. Surgery and other invasive procedures are not without risk, and at the end of the day it's a risk/benefit calculation.
