AbstractThe clinical examination of a comatose patient may be divided into neurological ang general. The neurological examination aims at determining all that is proper to the state of coma, its complication, whatever they origin (mostly cerebral oedema and herniation) and its focal signs. As for the coma itself, one may distinguish between disorders of consciousness or perceptivity and disorders of wakefulness. Specific reactivity and reactivity to pain. This must be combined with a study of muscle tone (reactions in flexion and extension, reflexes). Reflexes of the brain stem, nowadays better known, provide for a better assessment of severity and a better evaluation of tiered suffering. Vegetative symptoms, including respiration, cardiovascular system, temperature, trophicity, sphincteral function, must be studies in all comas. The classification of comas into stages of severety and the relevant scores (Glasgow, Liège) must be known with their advantages and limitations. The general clinical evaluation, including past history and associated signs, may suggest an aetiological diagnosis and point to the necessary paraclinical explorations.
