What to do about a hematoma should generally start with identifying the location of the hematoma. If a patient has a hematoma, it is located in the epidermis of the body. For subcutaneous hematomas, it is necessary to first control the development of the hematoma by applying pressure bandages, resting, reducing activities, and observing changes in the size of the hematoma. If the hematoma is controlled and slowly subsides and reduces, symptomatic treatment is sufficient. If the subepidermal hematoma becomes heavier and larger, or even secondary to painful infection, a dieting skin incision is required to give removal of the hematoma followed by compression bandaging. In this case, internal gauze and oil gauze strips should also be filled to stop bleeding by compression. If the hematoma can recover slowly is the best case, and as much as possible without surgery. In the case of intra-abdominal hematoma, it is also observed by checking ultrasound and CT to understand the change in the condition of the hematoma, which requires absolute bed rest. If the hematoma becomes heavier and heavier, or even ruptures leading to increased bleeding, emergency surgery is also required.
