       hai
       trauma triad of death
       it is imp to know what ultimately causes death after severe
       trauma
       a phrase ,  i feel an orthopod should be aware
       Trauma triad of death
       From Wikipedia, the free encyclopedia
       
       
       Triad of death
       The Trauma triad of death is a medical term describing the
       combination of hypothermia, acidosis and coagulopathy.[1] This
       combination is commonly seen in patients who have sustained
       severe traumatic injuries and results in a significant rise in
       the mortality rate.[2]
       The three conditions share a complex relationship; each factor
       can compound the others, resulting in high mortality if the
       cycle continues uninterrupted.
       Severe hemorrhage in trauma diminishes oxygen delivery, causing
       the patient's body temperature to drop (hypothermia). This in
       turn can halt the coagulation cascade, preventing blood from
       clotting (coagulopathy).
       In the absence of blood-bound oxygen and nutrients
       (hypoperfusion), the body's cells burn glucose anaerobically for
       energy (lactic acidosis), which in turn increases the blood's
       acidity (metabolic acidosis). Such an increase in acidity can
       reduce the efficiency of the heart muscles (myocardial
       performance), further reducing the oxygen delivery and hence
       triggering a deadly cycle.
