Prohovnik I, et al.

HD

7

Cerebral rSO₂ in HD patients was lower than healthy control, and cerebral rSO₂ was negatively correlated with dialysis duration.

[19]

Papadopoulos G, et al.

HD&PD

23 (HD), 9 (PD)

Cerebral rSO₂ in HD patients was lower than that in PD patients at preoperative condition.

[22]

Hoshino T, et al.

HD

18

Cerebral rSO₂ in HD patients was lower than healthy control, and cerebral rSO₂ did not change during HD.

[20]

Ito K, et al.

HD

54

Cerebral rSO₂ in HD patients was lower than healthy control, and cerebral rSO₂ was independently correlated with pH, dialysis duration, serum albumin, and diabetes mellitus.

Ito K, et al.

HD

16

Cerebral rSO₂ in HD patients with severe anemia was lower than that in Hb well-controlled HD patients, and blood transfusion improved cerebral rSO₂.

MacEwen C, et al.

HD

58

Cerebral rSO₂ was linearly dependent blood pressure below mean arterial pressure 60 mmHg.

[23]

Malik J, et al.

HD

17

Cerebral rSO₂ was drop in the minimum value during the first 35 min, but cerebral rSO₂ did not change between before HD and after HD.

[24]

Ito K, et al.

HD

108

Cerebral rSO₂ was correlated with aortic arch calcification by chest X-ray.

Matsukawa S, et al.

HD

9

Cerebral rSO₂ in HD patients was lower than that in non-HD patients, although SpO₂ did not differ between HD and non-HD patients.

Kovarova L, et al.

HD

39

Decreased cerebral rSO₂ was associated with cognitive impaired.

Ookawara S, et al.

HD

44

Cerebral rSO₂ did not change during HD, and it was lower than liver rSO₂ from HD initiation to the end.
