NCT04362423

Brief Summary

This is a three-phase pilot prospective study to develop a devise capable of detecting changes in cortical blood volume and oxygenation due to noxious stimuli. The hypothesis of the study is that optical signal changes corresponding to blood volume and oxygenation will be detected with functional near infrared spectroscopy in the prefrontal cortex of children under general anesthesia in response to peripheral noxious stimuli produced from the neurophysiological monitoring (SSEP).

Outcome Measures

Primary Outcomes (1)

  • the changes of oxy-, deoxy-, total-hemoglobin

    during stimulation (16 minutes)

Study Arms (3)

propofol+fNIRS

During data collection, only propofol is used to maintain the anesthesia. Peripheral noxious stimuli produced from the neurophysiological monitoring (SSEP)

Device: fNIRS

sevoflurane+fNIRS

During data collection, only sevoflurane is used to maintain the anesthesia. Peripheral noxious stimuli produced from the neurophysiological monitoring (SSEP)

Device: fNIRS

neuro-stimulator+fNIRS

During data collection, we use neuro-stimulator to give the stimulation.

Device: fNIRS

Interventions

fNIRSDEVICE

Near infrared spectroscopy (NIRS) is a non-invasive, portable, relatively inexpensive optical technology similar to pulse oximetry except that it measures total hemoglobin, oxy-hemoglobin, and deoxyhemoglobin in brain tissue (capillaries) rather than arteries.

Also known as: Functional Near Infrared Spectroscopy
