57 Review neuromonitoring Timing TCD Results Mortality (%) Limitations Grade TCD at pre hypothermia, Hypothermia and rewarming measuring bilateral MCA (peak flow velocity , end diastolic velocity, mean flow velocity and pulsatility index) -All pts with reversal diastolic flow or undetectable flow died. -Normal pulsatility index led to better outcome during hypothermia and rewarming (P= 0.002 and 0.0003) -Normal mean flow velocity during rewarming led to better outcome (P=0.009) 29% -Retrospective -Small cohort -Probable impaired autoregulation with influence on TCD. -Non blinded clinicians -Only 1 TCD operator -Confounders not investigated -Crude outcome scale 2B 2
