The aim of this study is to identify the predictive indexes for post-traumatic coma prognosis, which is important to better direct acute and subacute treatments and rehabilitation efforts. The pattern of sleep organization is a potential prognostic marker, but its role has not been established yet in the context of modern critical care. In the present study, we used a new protocol to evaluate the prognostic value of the different levels of sleep-wake organization recorded at the subacute stage of post-traumatic coma. ⋯ Our study demonstrates that the sleep-wake organization pattern based on 24h polysomnographic recordings at the subacute stages of post-traumatic coma is a reliable prognostic marker, both for survival and for functional recovery.
