Doctors induce a coma to prevent inflammation and pressure in the brain, according to Everyday Health. Induced coma is applicable when all other methods fail to be effective, but not all doctors are convinced that it is effective.
To perform a medically induced coma, an anesthesiologist administers a barbiturate or a sedative to the patient, which induces the coma, explains Everyday Health. This limits much of the brain's activity, thus allowing it to rest. The patient is totally unresponsive. To avoid post-coma complications, such as immobility, muscle paralysis and muscle weakness, the doctor determines the coma duration by monitoring the patient's intracranial pressure.
