• Mechanism of Injury
    • Cerebral Hyperthermia (>37 degrees C) following rewaming during cardiopulmonary bypass and early post-CPB period may increase cerebral metabolic rate increasing risk for cerebral desaturation([FOOTNOTE=Kawahara F, Kadoi Y, Saito S, Goto F, Fujita N. Slow rewarming improves jugular venous oxygen saturation during rewarming. Acta anaesthesiologica Scandinavica. 2003;47(4):419-424.],[ANCHOR=View Abstract],[LINK=/content/covidien/websites/medtronic/com/en/covidien/support/clinical-evidence.html?id=883109])
    • Evidence suggests that hyperthermia also impairs cerebral autoregulation, potentially exacerbating the potential for neurological injury([FOOTNOTE=Joshi B, Brady K, Lee J, et al. Impaired autoregulation of cerebral blood flow during rewarming from hypothermic cardiopulmonary bypass and its potential association with stroke. Anesthesia and analgesia. 2010;110(2):321-328.],[ANCHOR=],[LINK=])
  • Associated Outcome
    • Uncontrolled hyperthermia following rewarming during cardiopulmonary bypass and early post-CPB period may lead to worse neurocognitive outcomes([FOOTNOTE=Grigore AM, Murray CF, Ramakrishna H, Djaiani G.
