Medication Algorithm (to be used by physicians making decisions regarding Pharmacological Management of Agitation and Aggression following TBI).For patients with LCFS scores of 3 to 5 who are in a PTA state, the care environment must be able to provide a low stimulation environment with structure and consistency of care including consistent staffing as well as orienting information and materials for patients. The use of a tilt table or other mechanical device will likely be required and should be available in any centre that cares for patients with low levels of consciousness (LCFS 1-2). The team may need to do prolonged observations and multiple trials to determine true responsiveness of those in prolonged VS. The degree of stimulation and mobilization needs to be monitored as the optimal balance of stimulation and rest is not known. There must be frequent reassessment using standardized assessments. As such, not all centres may be able to provide this level of specialized care, even with adequate resources to monitor and rehabilitate these challenging patients. Patients with disorders of consciousness, in particular coma or a minimally conscious state, require ongoing access to interdisciplinary and specialized care. Further, clinical care should focus on an orienting, structured, less stimulating environment with efforts focussed on minimizing use of restraints and sedating medications. Formal evaluation with validated tools is necessary given the fluctuating course of recovery associated with poor awareness typical at this level of recovery. Families can frequently play an important role.įor patients who are in a state of post-traumatic amnesia (PTA), it is necessary to document their progression to identify patterns of recovery and also to plan for when patients may be ready to progress to active sub-acute rehabilitation. Carefully and gradually mobilizing these patients helps reduce the potential adverse effects associated with immobilization. Close observation of responses to controlled stimuli allows for monitoring of progress. Multi-modal stimulation may improve outcomes but too much stimuli may be more than the injured brain can handle. Sensory stimulation in particular has been promoted as a means to facilitate recovery and counter the negative impact of sensory deprivation often present in institutional care. 50% of vegetative survivors of severe brain injuries are able to regain consciousness within one year of injury and up to 40% subsequently improve to a higher level of the GCS. This is important as treatment and prognosis is highly dependent on accurate differentiation of the type of disorders of consciousness (DOC). Clinicians must be aware that although the GCS is very useful for some aspects of traumatic brain injury (TBI) care, it is not a valid diagnostic tool for prolonged disorders of consciousness (PDOC), and more sensitive and refined assessment is required to categorize prolonged disorders of consciousness (PDOC). The Glasgow Coma Scale (GCS) is widely used in acute settings to evaluate the level of consciousness. The mainstay of diagnosis is clinical evaluation for evidence of localizing or discriminating behaviours indicating awareness of self or the environment. Research suggests that the responsiveness and environmental awareness of people in vegetative state (VS) or minimally conscious state (MCS) is often underestimated by clinicians. One in eight patients with severe closed head injury has been reported to suffer from prolonged coma and vegetative state as a consequence of the head injury. ![]()
