Monitoração Invasiva Versus Não Invasiva da Pressão Intracraniana no Traumatismo Cranioencefálico Marshall III

Intracranial pressure monitoring (ICP) has been the main axis of clinical support for patients with severe brain injury, since intracranial hypertension (ICH) is a frequent cause of secondary injury in neurocritical patients. Monitoring of ICP by invasive and non-invasive methods represents an essential modality in the clinical care of neurological conditions at risk of developing ICH. The objective of this study is to compare the results obtained through the invasive and non-invasive monitoring of ICP and to correlate with the literature data. We report a case of severe TBI, Marshall III, whose patient underwent implantation of intraparenchymal PIC catheter and transcranial Doppler (TCD) with bilateral cerebral artery insonation bilaterally during his ICU hospitalization. TCD is able to estimate the value of the ICP, besides allowing the analysis of the changes in the wave morphology of the blood flow velocity, since it presents a positive correlation with the increase of the ICP. It is an important tool in the ICU that can be used in cases of unavailability of invasive methods, however, it is more accurate when performed in conjunction with the invasive monitoring of ICP.
