Cerebral desaturation results from an imbalance between cerebral oxygen supply and demand resulting from either limited cerebral blood supply, inadequate oxygen content, or unmet cerebral metabolic demand.
A greater degree of intraoperative cerebral desaturation is associated with:
Cerebral desaturation is a common occurrence during cardiac surgery that may adversely affect clinical outcome([FOOTNOTE=Murkin JM, Adams SJ, Novick RJ, et al. Monitoring brain oxygen saturation during coronary bypass surgery: a randomized, prospective study. Anesthesia and analgesia. 2007;104(1):51-58.],[ANCHOR=],[LINK=]) and the cost of care.([FOOTNOTE=Goldman SM, Sutter FP, Wertan MA, Ferdinand FD, Trace CL, Samuels LE. Outcome improvement and cost reduction in an increasingly morbid cardiac surgery population. Semin Cardiothorac Vasc Anesth. 2006;10(2):171-175.],[ANCHOR=],[LINK=])
The INVOS cerebral/somatic oximeter provides clinicians with a trend of intraoperative regional cerebral oxygenation. The data obtained from rSO2 monitoring may be used to reverse decreasing cerebral perfusion and avert prolonged cerebral desaturation.2
INVOS-guided detection and correction of cerebral desaturation may assist clinicians in improving patient outcomes.6
