The gut bacteria make vitamin K and are killed by antibiotics. This decreases vitamin K levels and therefore the production of these clotting factors. Deficiencies of platelet function may require platelet transfusion while deficiencies of clotting factors may require transfusion of either fresh frozen plasma or specific clotting factors, such as Factor VIII for patients with hemophilia. Infection
Infectious diseases such as Ebola, Marburg virus disease and yellow fever can cause bleeding. Diagnosis/Imaging
Dioxaborolane chemistry enables radioactive fluoride (18F) labeling of red blood cells, which allows for positron emission tomography (PET) imaging of intracerebral hemorrhages. Classification
Blood loss
Hemorrhaging is broken down into four classes by the American College of Surgeons advanced trauma life support (ATLS). Class I Hemorrhage involves up to 15% of blood volume. There is typically no change in vital signs and fluid resuscitation is not usually necessary. Class II Hemorrhage involves 15-30% of total blood volume. A patient is often tachycardic (rapid heart beat) with a reduction in the difference between the systolic and diastolic blood pressures. The body attempts to compensate with peripheral vasoconstriction. Skin may start to look pale and be cool to the touch. The patient may exhibit slight changes in behavior. Volume resuscitation with crystalloids (Saline solution or Lactated Ringers solution) is all that is typically required. Blood transfusion is not usually required. Class III Hemorrhage involves loss of 30-40% of circulating blood volume. The patients blood pressure drops, the heart rate increases, peripheral hypoperfusion (shock) with diminished capillary refill occurs, and the mental status worsens.
