“…In previous investigations (38,39), complication rates were similar to those of cabled ICP sensors (40)(41)(42). Another telemetric device (Miethke/Aesculap Sensor Reservoir) has also been developed to measure ICP through an implanted ventricular shunt system (43,44). In principle, this could also be coupled to an EVD, but so far there are no reports testing the device in a neuro-intensive care setting.…”

Purpose of Review: Monitoring of intracranial pressure (ICP) is an important and integrated part of the treatment algorithm for children with severe traumatic brain injury (TBI). Guidelines often recommend ICP monitoring with a treatment threshold of 20 mmHg. This focused review discusses; (1) different ICP technologies and how ICP should be monitored in pediatric patients with severe TBI, (2) existing evidence behind guideline recommendations, and (3) how we could move forward to increase knowledge about normal ICP in children to support treatment decisions.

“…Technical errors might be another reason for diverging measurements. Antes at al, registered a technical error rate of the sensor reservoir ® of 8 % [8]. Several authors found error rates between 3 and 16 % for the parenchymatous ICP probes [1,2,8,19,20].…”

“…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].…”

“…However, since the introduction of the Sensor Reservoir by Miethke Company in 2015, there is another telemetric ICP system available for verification of subtle drainage-related shunt failure and controlling and optimizing valve setting adjustment [4,7]. Opposite to the p-Tel probe which has to be explanted after 3 months, the shunt sensor does not have to be explanted.…”
