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. |
