Hypovolemic shock, including hemorrhagic shock and traumatic shock. In hemorrhagic shock, treatment requires active blood volume replacement and management of the primary disease. Care should be taken to stop the bleeding at the same time to avoid further development of the disease and cause organ damage. Traumatic shock, also classified as hypovolemic shock, treatment also requires volume expansion. It is treated essentially the same as hemorrhagic shock, but because there may be clots, plasma and inflammatory exudate that accumulate in body cavities and deep tissues, a detailed examination must be performed to accurately estimate the amount lost. For post-traumatic painful irritation, analgesics and sedatives can be applied and the injured area can be properly and temporarily immobilized. For life-threatening trauma, such as open pneumothorax, tension pneumothorax, and hypothorax, necessary emergency treatment should be done.
