“…This study has some limitations. First, the changes in cerebral hemodynamics measured by NIRS are in the frontal lobe just beneath the sensor on the forehead 7 . The middle cerebral artery supplies blood to that part of frontal lobe.…”

“…First, we can noninvasively measure cerebral oxygenation (ScO 2 ) by NIRS. Currently, ScO 2 monitoring is widely used to detect cerebral perfusion abnormalities in cardiac and non‐cardiac surgeries 6,7 . In addition, it was reported that the intraoperative decrease in ScO 2 was related to postoperative delirium and/or cognitive dysfunction, especially in cardiac surgery 6,7 .…”

Aim To measure the changes in cerebral oxygenation indices by near infrared time‐resolved spectroscopy and the cerebral blood flow simultaneously after spinal anesthesia for cesarean section. Methods This prospective observational study was conducted for 25 pregnant women scheduled for elective cesarean section under spinal anesthesia. During a period of 15 min after spinal anesthesia, cerebral oxygenation (ScO2), and the total cerebral hemoglobin concentration (tHb) were measured using near infrared time‐resolved spectroscopy and mean cerebral blood flow velocity (Vm) was measured using transcranial Doppler ultrasonography. Next, in the women who had nausea during the observed period, we compared these values when nausea was detected with those when it was not. Results Mean arterial pressure (MAP) decreased to around 60 mmHg (by 25% compared to the control) 6 min after spinal anesthesia. Compared to the control, ScO2 decreased by about 3% after 6 min and then gradually increased. The tHb, which reflects cerebral blood volume started to decrease just after spinal anesthesia and this continued until 12 min (the decrease was about 12%). Vm decreased by about 7%. In the 14 women who had nausea, MAP, Vm, and ScO2 values when nausea was detected were significantly lower than when it was not. Conclusion The changes in cerebral hemodynamics may be small after spinal anesthesia in ordinary cesarean section compared to the reduction of systemic arterial blood pressure. There might be greater decreases in cerebral blood flow and oxygenation when nausea occurred in the pregnant women who experienced it after spinal anesthesia.

“…Unlike conventional fingertip pulse oximetry, ScO 2 does not rely on a pulsating flow, and reflects the balance between oxygen supply and demand in the arteriolar, capillary and venular beds of the brain cortex underlying the prefrontal area over the sensor is located. Detailed cerebral oximetry guidelines have recently been drawn up by the Japanese Society of Cardiovascular Anesthesiologists [12].…”

SummaryTakayasu's arteritis is a rare vasculitis affecting the aorta and its branches. Disease progression can result in arterial stenosis and subsequent organ dysfunction. Estimating organ perfusion by measuring the peripheral blood pressure can be challenging because it may be altered by arterial stenosis. We report the case of a 61‐year‐old woman with Takayasu's arteritis with aortic and mitral regurgitation who presented for aortic valve replacement and mitral valvuloplasty. Peripheral arterial pressure was considered a less reliable surrogate for organ perfusion because the patient had diminished blood flow in both the lower and upper extremities. In addition to the bilateral radial arterial pressure, the blood pressure in the ascending aorta was monitored to estimate the patient's organ perfusion pressure during cardiopulmonary bypass. The initial target blood pressure was determined based on the pre‐operative baseline and modified by measurement of the aortic pressure. Cerebral oximetry using near‐infrared spectroscopy and mixed venous saturation was monitored to estimate oxygen supply‐demand balance, which helped evaluate cerebral perfusion and determine the transfusion threshold. The entire procedure was uneventful, and no organ dysfunction was observed postoperatively.
