Why the study?
How do blood pressure decreases during general anaesthesia compare to physiological decreases during natural sleep?
How do blood pressure decreases during general anaesthesia compare to physiological decreases during natural sleep?
Intra-operative blood pressure decreases are comparable to, though slightly greater than, physiological decreases seen during natural sleep, providing context for defining intra-operative hypotension.

Offers physiological context for intra-operative hypotension definitions; leaves open whether thresholds warrant revision.
