Chronic disorders of consciousness (DOC) develop after severe traumatic and non-traumatic brain damage and are characterized by the restoration of wakefulness in a patient after a coma without the recovery of consciousness. To optimize the diagnosis and treatment of patients with chronic DOC, a Russian working group on the problems of chronic DOC was organized, which included specialists in various areas, primarily anesthesiologists, critical care physicians and neurologists. While discussing the terminology of chronic DOC, the group identified that currently there is no definition for the state that falls into the period from the recovery of wakefulness and until 28 days after the brain damage when vegetative state/unresponsive wakefulness syndrome (VS/UWS) or minimally conscious state (MCS) may be diagnosed. In the intensive care unit (ICU) setting, there is often no consultant to provide critical care physicians with the correct diagnosis of the latter clinical syndromes, and neurophysiological tests are not feasible either. Therefore, there is a need to create a set of simple, understandable and easily reproducible strategies for managing this category of patients in the ICU. Thus, the working group proposed the term “prolonged disorders of consciousness” to be used for the patients with the signs of VS/UWS or MCS syndromes during their stay in the ICU until 28 days after initial brain damage and/or until the correct differential diagnosis of a type of chronic DOC is made. With the introduction of prolonged disorders of consciousness definition, the regular ICU staff will better understand how to provide an optimal set of supportive therapy and early rehabilitation activities in the lack of specific diagnostics techniques and dedicated specialists. Allocation of this category of patients allows us to create an algorithm for their better diagnosis and management and ensures consistent and effective interdisciplinary care at various levels. On the one hand, this approach will help us allow to free up ICU beds that are in high demand, while on the other, it will maximize the opportunity to realize the rehabilitation potential of DOC patients due to timely transfer to specialized centers. Conclusions. If the term “prolonged disorder of consciousness” is accepted by professional communities of specialists (critical care physicians, neurologists, neurosurgeons, etc.), it will be used in guidelines for the management of DOC patients.
