“…Another factor that could explain the differences in absolute ICP values is the zero drift of both measuring methods. A zero-point drift of the NEUROVENT ® -P-tel probe of ±2,5 mmHg has already been described in the literature [2,5,20]. However, the tendency of the ICP dynamics of both systems is largely synchronous in the present study despite the difference between the absolute ICP values.…”

“…An increase in ICP leads to a stretching of the membrane. These resistance changes are registered by a pressure transducer and converted into ICP values [2,18]. In this case, measurements are performed in the brain parenchyma at a depth of approx.…”

“…NEUROVENT ® -P-tel probe has been proven to be safe and effective in telemetric ICP monitoring and is used as reference in acute therapy of elevated ICP as well as for the diagnosis of neurological diseases such as pseudotumor cerebri and idiopathic normal pressure hydrocephalus (iNPH)[1,2,4,5,8,10,11].The sensor reservoir ® (Miethke, Aesculap, Germany) is available to determine pressure conditions continuously within a shunt system and thus to assess over-or under-drainage during shunt therapy. Radiation exposure of CT scan or long and expensive MRI for the diagnosis of over-or under-drainage symptoms can thus be avoided.…”

Objectives: Measurement of intracranial pressure (ICP) plays an important role in long-term monitoring and neuro-intensive treatment of patients with a cerebral shunt. Currently, only two complete telemetric implants with different technical features are available worldwide. This prospective pilot study aims to examine patients who had both probes implanted at overlapping times for clinical reasons and represents the first in vivo comparison of both measurement methods.Materials and methods: Patients with a primary subarachnoid hemorrhage or a spontaneous intracerebral hemorrhage with ventricular hemorrhage who had received a telemetric ICP probe (Raumedic® NEUROVENT®-P-tel) were included in the study. Conventional external ventricular drainages (EVD) and ventriculoperitoneal shunts with a telemetric ICP probe (Miethke Sensor Reservoir) were implanted in patients with hydrocephalus who required CSF (cerebrospinal fluid) drainage. ICP values from all systems were obtained. Due to the overlapping implantation time, parallel ICP measurements were performed via two devices simultaneously. ICP measurements via the sensor reservoir were repeated after three, six and twelve months. Differences between the ICP values measured via the NEUROVENT®-P-tel probe, the Miethke sensor reservoir®, and the EVD were analyzed.Results: Sixteen patients were included in the present study between 2016 and 2018. 63% of all patients were male. In 11 patients the ICP measurements were followed up with both devices for 3 months. ICP measurements of the sensor reservoirs showed corresponding trends in 9 cases compared to ICP measurement via the telemetry probe or EVD. Difference in ICP values ranged between 14,5 mmHg and 0,0 mmHg. The average difference of the ICP values in 8 cases was ≤ 3,5 mmHg.Conclusion: ICP measurements with both systems continuously showed synchronous ICP values, however absolute values of ICP measurement with the different systems did not match.

“…The advantage of telemetric ICP monitoring in comparison with conventional ICP monitoring, besides a lower infection rate due to the closed system used, is the possibility to record the ICP within greater time intervals, at any time and for longer periods [1][2][3][4][5][6][7][8]12].…”
