[The use of evoked potentials in the follow-up and prognosis of patients in coma following severe traumatic brain injury].

Introduction: When dealing with patients in coma, it can be very useful to have early access to objective tests that provide information about their clinical status and can help to establish a prognosis for survival and functional recovery. The value of evoked potentials (EP) in such cases is already well known, although only techniques that assess the neurological status have been used.

Aim: To determine the usefulness of different types of evoked potentials as a means of reaching a short and medium term prognosis for survival and functional recovery in patients in coma as a result of traumatic brain injury (TBI).
