Neither Desflurane nor Isoflurane Alters Aβ40 to Tau Ratio in Human CSF at 2 Hours after the Anesthesia

	S (N = 35)	SD (N = 33)	SI (N = 38)	F Values	P Values
Aβ40/Tau—2 h	27.45 ± 9.94	25.88 ± 9.63	27.10 ± 11.14	3.48	0.04
Aβ40/Tau—24 h	24.75 ± 8.53	29.07 ± 9.87	30.11 ± 10.25	2.43	0.09

The Aβ40 to tau ratio in human CSF is not significantly different among the surgery under S (N = 35), SD (N = 33), and SI (N = 38) anesthesia groups at 2 or 24 h after the surgery under anesthesia.

Aβ = β-amyloid protein; CSF = cerebrospinal fluid; S = spinal; SD = spinal plus desflurane; SI = spinal plus isoflurane.
