Telemetric ICP Measurement with the First CE-Approved Device: Data from Animal Experiments and Initial Clinical Experiences

摘要: The objective was to evaluate the qualification of new telemetric intracranial pressure (ICP) measurement (t-ICP) device Raumedic® NEUROVENT P-Tel and S-Tel. proof concept examined in a pilot animal study measuring intraperitoneal with conventional ICP probe at five rates for 1 h each. Moderate external load allowed values between 0 40 mmHg. To estimate long-term performance 18 t-ICP devices were implanted subdurally or intraparenchymally into minipigs. Reference measurements performed regularly using probes. From short-term as well from perspective proved have excellent dynamic signal components perception (e.g. pulse amplitude). Some zero drift static found, ranging 5 8 While all telemetric, intraparenchymal probes kept their functionality throughout follow-up, 33% subdurals failed reasons detailed another paper. Raumedic’s NEUROVENT® P-Tel/S-Tel provide reliable data over periods up months. Minor can be tolerated is measured stability. Clinicians should focus more on such information than when longer follow-up periods.
