Overview

Performance Assessment of the PMD-200, a Novel Pain Monitor, in Subjects at Neurointensive Care Unit.

The proposed study is design to further demonstrates the performance of the Nociception Level (NoL) Index in neurological impaired anesthetized patients under general anesthesia, by evaluating its response to controlled changes in the levels of noxious stimuli/analgesia, and to correlate the NoL response to the EEG derived pain score. Validating the performance of the NoL Index may provide a tool to monitor the pain/nociception in this population. In this study, the PI plan to demonstrate that the NoL Index is a continuous index. It is anticipated that a higher level of nociception will correspond to a higher NoL index. On the other hand, it is anticipated that higher levels of analgesic agent for the same noxious stimulus will lead to a lower NoL index. The participants will be monitored as in a typical ICU and according to the local guidelines by various types of monitoring devices, such as: vital signs, pulse oximeter, Bispectral Index (BIS), Electroencephalography (EEG) etc.

Interventions

PMD-200DEVICE

the patients will be monitored by PMD-200. The technology consists of measurements of a number of nociception-related physiological parameters that corresponds with the autonomic nervous system's response to noxious stimuli, and using the company's proprietary algorithms, 'translating' these measurements into an index that represents the nociceptive response, the NoL™ (Nociception Level) Index. The NoL index is a relative index from 0 to 100, while 0 is "no pain/nociception" and 100 is "extreme pain/nociception".

EEG monitorDEVICE

An EEG device will be connected to the patient and display the Spectral Edge Frequency (SEF) signals and values on the subject monitor.

Outcomes

Primary Outcomes

Correlation between changes in the nociception levels of the subject (NoL Index value) prior and following a noxious stimuli

To demonstrate that the NoL Index is correlates with changes in the nociception levels of the subject prior and following a noxious stimuli.

Time frame: Through study completion, about one year

Secondary Outcomes

Correlation between changes in the nociception levels of the subject (NoL Index value) to other nociception predictors (HR, NIBP)

The NoL values can be correlate to other nociception predictors (e.g heart rate, blood pressure) following a noxious stimuli.

Time frame: Through study completion, about one year

Correlation between the NoL index and the EEG derived pain score

To assess the correlation between the NoL index and the EEG derived pain score during arousal response caused by noxious stimuli

Time frame: Through study completion, about one year
