In the hospital, the emergency department and the operating room are always the busiest and most critical departments, bearing the greatest responsibility.
When a trauma patient is rushed to the hospital, the first department they encounter is the emergency department. After a series of exams and tests, if the patient's condition is stable, they will either stay in the emergency department or be observed in a related department such as orthopedics or general surgery for conservative treatment. However, if the patient's condition is severe, emergency surgery is required to remove the factors threatening their life.
Emergency surgery is a high-risk medical procedure. Take a spleen rupture for example. Once diagnosed upon admission, the patient must undergo immediate splenectomy. The spleen is a significant blood storage organ in the body, and the greatest risk during surgery is massive bleeding, which necessitates urgent blood preparation for the operation.
