Résumé
Refractory intracranial hypertension (RIH) refers to a dramatic increase in intracranial pressure (ICP) that cannot be controlled by treatment and leads to patient death. Detrimental sequelae of raised ICP in acute brain injury (ABI) are unclear because the underlying physiopathological mechanisms of raised ICP have not been sufficiently investigated. Recent reports have shown that autonomic activity is altered during changes in ICP. The aim of our study was to evaluate the feasibility of assessing autonomic activity during RIH with our adopted methodology. We selected 24 ABI patients for retrospective review who developed RIH. They were monitored based on ICP, arterial blood pressure, and electrocardiogram using ICM+ software. Secondary parameters reflecting autonomic activity were computed in time and frequency domains through the continuous measurement of heart rate variability and baroreflex sensitivity. The results of the analysis will be presented later in a full paper. This preliminary analysis shows the feasibility of the adopted methodology.
