Cerebral Desaturation during Cardiac Surgery

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.

Up to 37% of patients experience cerebral desaturation during cardiac surgery¹

Three quarters of patients experience cerebral desaturation during high-risk cardiac surgery²

A greater degree of intraoperative cerebral desaturation is associated with:

• Increased incidence of postoperative cognitive dysfunction³
• Increased incidence of postoperative delirium⁴
• Increased hospital length of stay in high risk patients⁵
• Increased ICU length of stay in high risk patients⁵

Cerebral desaturation is a common occurrence during cardiac surgery that may adversely affect clinical outcome⁶ and the cost of care.⁷

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

Compared to controls, INVOS-guided reduction of cerebral desaturation:

• Reduced mean cerebral desaturation time by 39%⁸
• Reduced permanent stroke by 51.74%⁹
• Reduced the incidence of prolonged postoperative mechanical ventilation by 35.85%⁹
• Reduced ICU length of stay by 30.74%⁶
• Reduced post-operative cognitive decline by 46.15%¹⁰
• Reduced major organ morbidity and mortality by 72.72%⁶
