Comparison of Automated and Manual Recording of Brief Episodes of Intracranial Hypertension and Cerebral Hypoperfusion and Their Association with Outcome After Severe Traumatic Brain Injury

Abstract : Adult admissions to a Level I urban trauma center between 2008 and 2010 were reviewed to seek patients with concurrent intraventricular catheter (IVC) and intraparenchymal (IPM) intracranial pressure (ICP) monitor placements. Time periods when ICP data were recorded from both devices were analyzed and compared. While IPM ICP measurements were autonomously recorded at 6-second intervals, IVC ICP values were abstracted from nursing chart recordings. Our study revealed that in this retrospective cohort of 81 adult severe traumatic brain injury patients, IVCs used routinely with only intermittent ICP measurements undervalued ICP when compared to a continuous IPM device.
