It is thought that it may be caused by the body's inflammatory response to surgery, stress hormone release during surgery, ischemia, or hypoxaemia. [5] [6] Post-operative cognitive dysfunction can complicate a person's recovery from surgery, delay discharge from hospital, delay returning to work following surgery, and reduce a person's quality ...

Signs of death or strong indications that a human is no longer alive are: Respiratory arrest (no breathing); Cardiac arrest (no pulse); Brain death (no neuronal activity); The heart and lungs are vital organs for human life due to their ability to properly oxygenate human blood (lungs) and distribute this blood to all vital organs (heart).
Critics of this system point out that perioperative mortality may not reflect poor performance but could be caused by other factors, e.g. a high proportion of acute/unplanned surgery, or other patient-related factors. Most hospitals have regular meetings to discuss surgical complications and perioperative mortality.
Other causes include unfamiliarity with techniques used, e.g. intravenous anesthetic regimes, and inexperience. Most cases of awareness are caused by inexperience and poor anesthetic technique, which can be any of the above, but also includes techniques that could be described as outside the boundaries of "normal" practice.
Without special treatment after circulation is restarted, full recovery of the brain after more than 3 minutes of clinical death at normal body temperature is rare. [6] [7] Usually brain damage or later brain death results after longer intervals of clinical death even if the heart is restarted and blood circulation is successfully restored ...
The word apoplexy was sometimes used to refer to the symptom of sudden loss of consciousness immediately preceding death. Strokes , ruptured aortic aneurysms , and even heart attacks were referred to as apoplexy in the past, because before the advent of biomedical science , the ability to differentiate abnormal conditions and diseased states ...
The condition results from infection, injury (accident, surgery), hypoperfusion and hypermetabolism. The primary cause triggers an uncontrolled inflammatory response. [citation needed] Sepsis is the most common cause of multiple organ dysfunction syndrome and may result in septic shock.
