Reduced effectiveness of hypothermia in patients lacking the wave V in auditory brainstem responses immediately following resuscitation from cardiac arrest

The absence of the ABR wave V in the early phase after ROSC wave indicated a reduced effect of therapeutic hypothermia, even in cases that underwent hypothermia promptly after out-of-hospital CPA. Measurement of ABRs appears to be useful as a predictor of effectiveness and as a criterion for determining the indication for therapeutic hypothermia.
