[A preliminary study of synchronous evoked potential in newborn-infant auditory and visual function test].
OBJECTIVE
The purpose of this study is to bring out the consultable laboratory values of synchronous evoked potential in normal neonates and infants, investigate the characteristic of the electric response waveform, and explore its feasibility on applying to newborn auditory and visual function test as an electric physiology detection method.


METHODS
It was applied to go on measuring 19 cases of mature normal neonate (< or =4 days) and 11 cases of infants (< or =5 months), also comparing with the study of ABRs, FVEPs independently.


RESULTS
Get the electric response wave form results of synchronous electric evoked potential in both groups of newborn-infants, through comparing with the result of independent ABRs and FVEPs, the monitoring result demonstrated that there were an extreme significant changes of the corresponding parameters (wave I, III, V latency) (P<0.01), and there were no significant changes of I-III, III-V interwave latency (P>0.05); it also shows that ABRs impact on FVEPs in N2 wave latency of newborn group and P1 wave latency of infant group (P<0.01).


CONCLUSIONS
Auditory and vision pathway may be had communicated information by the neuron in the center. The technology of the auditory and visual synchronous evoked potential brings out the whole new electric physiology detection tools, it will definitely offer powerful technical support in step for newborn-infant auditory and visual function test.
