MECHANISM OF INJURY, ASSOCIATED OUTCOME AND INTERVENTION
Learn more about cannula misplacement causing cerebral desaturation:
Mechanism of Injury
Misplacement of cerebral perfusion cannula occurs more frequently than clinicians may be aware. Without continuous monitoring of cerebral regional oxygen saturation, there may be no mechanism to diagnose it.1
In 35 consecutive patients undergoing surgical repair of aortic arch aneurysm, cerebral oximetry detected acute cerebral desaturation due cannula malposition in 11.4% of patients. Cannula malposition was confirmed via orbital ultrasound.2
In patient undergoing aortic arch surgery, Rubio et al determined that incorrect placement of the arterial cannula was correlated with cerebral desaturation.1
Associated Outcome
Cannula malposition, if undetected, may lead to cerebral ischemia and potentially irreversible brain damage.2
