Firstly, it is necessary to administer IV fluids to the patient and establish two venous accesses to urgently replenish blood volume. Then, it is important to manage breathing to ensure the patient's airway is clear, and provide oxygen if necessary. Patient's vital signs should also be checked for any abnormalities. Additionally, treatment should be given based on the cause of bleeding. If the bleeding is due to poor uterine contraction, it is crucial to promptly enhance uterine contractions to quickly stop the bleeding. At this time, uterotonic agents can be used, or manual uterine massage can be employed to stem the bleeding. If the bleeding is caused by a surgical incision, then the incision needs to be sutured properly.
