Eeg polysomnography as a powerful diagnostic and prognostic methodin evaluation of brain damage in neonates and infants

EEG polysomnography is a powerful tool for the diagnosis and the prognosis of brain injuries in premature and full term neonates and infants. This method includes EEG /electroencephalography/, EOG /electrooculography/, EMG /electromyography/, ECG /electrocardiography/, respiration monitoring and video recording. We utilize polysomnographic montage that represents specific modification of electrode placement. We use silver/silver chloride disc recording electrodes with 1 metre anti-tangle, flexible, silicone leads in six different colours. Respiration has been detected on two levels: nasal and thoracal. EEG recording has been done in natural sleep (without any premedication), in interfeeding interval during at least one sleep cycle. EEG polysomnography is indicated in high risk neonates and infants. This method has an important role in evaluation of brain maturation, early detection of brain damage and in long-term neuromotor and developmental prognosis in high risk children. The prognostic value of EEG polysomnography is more sensitive when it is used as early as possible after brain damage and in serial EEG recordings.
