Amplitude-integrated electroencephalograms (aEEGs) recorded by cerebral function monitors (CFMs) are used increasingly to monitor the cerebral activity of newborn infants with encephalopathy. Recently, new CFM devices became available which also reveal the original EEG signals from the same leads. To date it was unclear whether this single-lead EEG provides additional information towards interpreting the aEEG traces more accurately. Our report deals with three cases in which the single-lead EEG from the CFM device did indeed reveal important additional information not provided by the aEEG alone. In cases 1 and 3, the aEEGs showed drifting of the baseline to higher amplitudes. The single-lead EEG revealed that this was due to muscle artefacts, high-frequency oscillation ventilation and the electrocardiogram rather than to cerebral activity. Hence, without knowledge of the EEG, the aEEG trace might have been misinterpreted as being fairly normal. Case 2 showed paroxysmal elevation of the lower margin of the amplitude on the aEEG which looked like epileptic activity. However, additional information from the single-lead EEG revealed that it was due to muscle artefacts. Thus, simultaneously recorded EEG can help to interpret seizure-like episodes on the aEEG. CONCLUSION: Simultaneously recorded single-lead EEGs can help to interpret aEEG traces more accurately. |
