Abstract

Prediction of neurological function in post cardiac arrest patient with ROSC (return of spontaneous circulation) is a challenge for emegency physician. Although many modern methods to maintain the circulation, relatively lack of tools to evaluate the mental status, beside the clinical judgement and radiology. The BIS score (bispectral index) provide a EEG variation information is an option alternatively. We conducted a study measured the BIS score in 31 patients with ROSC to predict the outcome of recovery at day 30 aftermatch. We used the CPC (Cerebral Performance Category) range from 1 to 5, regarding of fully recovery to death. The result revealed that: the BIS score on admission had the AUC of 0,827, cutoff point 43,5 with the sensitivity of 79,2%, the specificity of 85,7%. If the cutoff reduce to 23, the sensitivity chang to 33,3%, but the specificity reach 100%. The BIS score at 72 hour after cardiac arrest demonstrated the AUC of 0,888, cutoff point of 53, sensitivity 92,9%, specificity of 71,4%. Two patients have experienced the BIS score of 0 in the first 24 hour, they all died inhospital. Conclusion: BIS score has been proven to be a predict factor for neurologic outcome in post cardiac arrest patient with ROSC.
