Chapter 8 - Management of the comatose patient

Abstract

Coma has many causes but there are a few urgent ones in clinical practice. Management must start with establishing the cause and an attempt to reverse or attenuate some of the damage. This may include early neurosurgical intervention, efforts to reduce brain tissue shift and raised intracranial pressure, correction of markedly abnormal laboratory abnormalities, and administration of available antidotes. Supporting the patient's vital signs, susceptible to major fluctuations in a changing situation, remains the most crucial aspect of management. Management of the comatose patient is in an intensive care unit and neurointensivists are very often involved. This chapter summarizes the principles of caring for the comatose patient and everything a neurologist would need to know. The basic principles of neurologic assessment of the comatose patient have not changed, but better organization can be achieved by grouping comatose patients according to specific circumstances and findings on neuroimaging. Ongoing supportive care involves especially aggressive prevention of medical complications associated with mechanical ventilation and prolonged immobility. Waiting for recovery-and many do- is often all that is left. Neurorehabilitation of the comatose patient is underdeveloped and may not be effective. There are, as of yet, few proven options for neurostimulation in comatose patients.
