项目摘要

PROJECT SUMMARY Present day multimodal monitoring for traumatic brain injury (TBI) is limited in its implementation as it necessitates multiple invasive probes to measure intracranial pressure (ICP), intracranial EEG (icEEG), intracranial temperature (icT), and brain tissue oxygen (PBTO2), the majority of which require their own instrumentation and monitors. While there is increasing evidence to support multimodal monitoring in TBI and other acute brain injuries, the present cumbersome systems make it nearly impossible to use outside of major Level 1 trauma centers. The challenges include the need for expertise with both probe placement and data interpretation as well as the integration of multiple electronic units from different vendors with diverse software systems, each requiring training, IT and biomedical engineering support. Coupled with this is an increased risk of bleeding and infection from the multiple entry points into brain parenchyma. Our objective is to develop a single source brain monitoring solution for the management of severe TBI. We will integrate the modalities indicated for severe TBI (ICP, icEEG, icT, PBTO2) in a brain implantable device called the NeuroProbe with a target diameter which is equivalent to, or smaller than, individual current probes. We will develop a single interface device called the NeuroLink to acquire the multi-modal intracranial data from the NeuroProbe as well as scalp EEG and patient physiological data including systemic blood pressure (SBP), heart rate (HR), mean arterial pressure (MAP) and blood oxygen (SpO2) and transmit these sensor signals to monitors as a time- locked single digital data stream. We will develop a display unit called the NeuroMonitor to analyze and display the acquired multimodal data in a synchronized real-time manner. We call the composite solution created by the NeuroProbe, NeuroLink, and NeuroMonitor devices the NeuroProbe Solution. The technological development of the NeuroProbe Solution dramatically expands the capabilities of the existing icEEG depth electrodes developed at Yale University and multimodal probes currently on the market. The key innovations of the NeuroProbe Solution are: 1. Integration of multiple physiologic sensors on a single intracranial probe (NeuroProbe). 2. Simplification of NeuroProbe to allow placement at bedside in a civilian or military facility. 3. Development of a multimodal interface device (NeuroLink) to store and relay time-locked digital data acquired from the NeuroProbe and extracranial sensors to the NeuroMonitor and other clinical monitors. 4. Development of an iPad sized monitor (NeuroMonitor) to analyze and display multimodal data. 5. Time-locked multi-stream data transfer which allows for real-time and post-hoc data review and analysis. This innovative solution allows acquisition and integration of data from multiple physiological parameters through a standard small tablet creating a simple single end-to-end solution from sensors to multimodal data analysis and display in an otherwise fragmented and complex domain.
