Key result
Severe unilateral rSO2 decrease after anesthesia induction does not result in postoperative neurological abnormalities.
Case Report (n=1)
NIRS-measured regional cerebral oxygen saturation decreases do not always correlate with postoperative neurological complications in cardiac surgery.
Unilateral NIRS desaturation after induction should not yet change practice; leaves open its prognostic value in larger prospective cohorts.
Measurement of regional cerebral oxygen saturation (rSO2) using near-infrared spectroscopy (NIRS) in cardiac surgery is known to be useful in reducing postoperative neurological complications. We here present a case of a 71-year-old man in whom severe decrease in unilateral rSO2 was observed after induction of general anesthesia for percutaneous mitral valve clipping, although no neurological abnormalities were found. NIRS does not always predict postoperative neurological complications.

Honda et al. (2023) conducted a case report in percutaneous mitral valve clipping (n=1). Measurement of regional cerebral oxygen saturation (rSO2) using near-infrared spectroscopy (NIRS) was evaluated on postoperative neurological complications. A severe decrease in unilateral regional cerebral oxygen saturation measured by NIRS after induction of general anesthesia did not result in postoperative neurological abnormalities.
