The Coma is the morbid condition characterized by loss of consciousness with reduced o absent responsiveness to sensory stimuli and preservation of function vegetative. Four levels of coma are distinguished: awake coma, mild coma, coma medium and deep coma. Symptoms are variable depending on the cause and the coma level.
Immediate procedures are needed to intervene: check motor response, pupils, and verbal response. Regarding the medical history, one needs to assess the time and mode of onset, past or coincidental trauma, past or current illnesses taking drugs or toxicants. Laboratory tests such as CBC, blood glucose, azotemia, electrolytes, transaminases, amylasemia, creatininemia, and urinalysis should be performed.
