Abstract:
Objective To investigate neonatal cerebral oxygenation after hypoxia.Methods Cerebral oxygenation of 39 babies with perinatal hypoxia and 42 neonates without hypoxia was ob- served under quiet state and stimulation of sound by Near Infrared Spectroscopy(NIRS) and com- paired with the findings of EEG and image studies.Results In normal neonates cerebral oxygena- tion was steady under quiet state,where as it increased after sound stimulation.However,newborns with hypoxia showed inhibited brain activities with little changes in cerebral oxygenation in response to sound stimuli.Episodes of deoxygenation were found in 13 cases during monitoring.Conclusion After perinatal hypoxic brain damage,the function of cerebral oxygenation can be still abnomal for a certain period,which is related to the degree of brain damage.
