Short-latency cortical somatosensory evoked responses of preterm infants with ultrasound abnormality of the brain.
Somatosensory evoked response (SER) testing was carried out on 30 neonates with abnormality of the brain diagnosed by ultrasound, and the results were compared with previously defined normal ranges. The N1 peak latencies of the cortical SER were significantly different from normal, but peripheral nerve conduction velocities were not. Early neurological follow-up of these infants suggests that the cortical SER shows good correlation with neurological and developmental outcome, and may provide useful additional diagnostic information to cranial ultrasound for these high-risk infants.
